useRequestHeaders returned undefined after deployed to the server.

I tried to create a wrapper for every fetch request on my project like this

// @/service/config.ts
const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const { cookie } = useRequestHeaders(['cookie'])

  const API_BASE_URL = import.meta.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = import.meta.server
    ? config.authorization
    : config.public.authorization

  return {
    baseURL: API_BASE_URL,
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
      cookie
    },
    server: true
  }
}

export default getAPIRequestConfig

// @/service/config.ts
const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const { cookie } = useRequestHeaders(['cookie'])

  const API_BASE_URL = import.meta.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = import.meta.server
    ? config.authorization
    : config.public.authorization

  return {
    baseURL: API_BASE_URL,
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
      cookie
    },
    server: true
  }
}

export default getAPIRequestConfig

// @/service/makeRequest.ts
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const {
      status,
      data: { value: response },
      execute
    } = await useFetch(url, {
      ...getAPIRequestConfig(),
      method,
      ...options,
      onResponseError: ({ response }) => {
        if (response.status === 401) {
          // do smt
        }
      }
    })

    return { status, response, execute }
  } catch (err: any) {
    // do smth

    return false
  }
}

export default makeSSRRequest

// @/service/makeRequest.ts
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const {
      status,
      data: { value: response },
      execute
    } = await useFetch(url, {
      ...getAPIRequestConfig(),
      method,
      ...options,
      onResponseError: ({ response }) => {
        if (response.status === 401) {
          // do smt
        }
      }
    })

    return { status, response, execute }
  } catch (err: any) {
    // do smth

    return false
  }
}

export default makeSSRRequest

// @/service/endpoints/endpointsSample.ts
import makeRequest from '../makeRequest.ts'

const endpointsSample = {
  getSomething: () => makeRequest('GET', '/url-sample/'),
  postSomething: () => makeRequest('POST', '/url-sample/'
}

export default endpointsSample

// @/service/endpoints/endpointsSample.ts
import makeRequest from '../makeRequest.ts'

const endpointsSample = {
  getSomething: () => makeRequest('GET', '/url-sample/'),
  postSomething: () => makeRequest('POST', '/url-sample/'
}

export default endpointsSample

---

// @/pages/something.vue
import endpointsSample from '@/service/endpoints/endpointsSample'

const { data: dataResponse } = await endpointsSample.getSomething()

// @/pages/something.vue
import endpointsSample from '@/service/endpoints/endpointsSample'

const { data: dataResponse } = await endpointsSample.getSomething()

worked just fine during local development, the cookies also attached to the request header, but after I deployed it to the server it returned undefined, why? thx

Hi @yangku. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can explain why you're experiencing this issue with useRequestHeaders returning undefined after deploying to the server. The useRequestHeaders composable is designed to access the incoming request headers within your Nuxt application. However, it's important to note that this composable behaves differently on the client-side and server-side. According to the Nuxt documentation on useRequestHeaders: "In the browser, useRequestHeaders will return an empty object." This explains why you're seeing undefined values after deployment. When your application is running on the client-side (in the browser), useRequestHeaders doesn't have access to the original server request headers, so it returns an empty object. To address this issue and ensure that cookies are properly forwarded in both server-side and client-side contexts, you should consider using useRequestFetch instead. This composable is designed to forward the request context and headers when making server-side fetch requests. Here's how you can modify your getAPIRequestConfig function to use useRequestFetch:

// @/service/config.ts
const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const requestFetch = useRequestFetch()

  const API_BASE_URL = import.meta.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = import.meta.server
    ? config.authorization
    : config.public.authorization

  return {
    baseURL: API_BASE_URL,
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
    },
    server: true,
    fetch: requestFetch
  }
}

export default getAPIRequestConfig

// @/service/config.ts
const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const requestFetch = useRequestFetch()

  const API_BASE_URL = import.meta.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = import.meta.server
    ? config.authorization
    : config.public.authorization

  return {
    baseURL: API_BASE_URL,
    headers: {
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
    },
    server: true,
    fetch: requestFetch
  }
}

export default getAPIRequestConfig

By using useRequestFetch, you ensure that the request context and headers (including cookies) are properly forwarded in both server-side and client-side environments. Additionally, in your makeSSRRequest function, you should use the fetch option provided by getAPIRequestConfig:

// @/service/makeRequest.ts
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const config = getAPIRequestConfig()
    const {
      status,
      data: { value: response },
      execute
    } = await useFetch(url, {
      ...config,
      method,
      ...options,
      onResponseError: ({ response }) => {
        if (response.status === 401) {
          // do smt
        }
      }
    })

    return { status, response, execute }
  } catch (err: any) {
    // do smth

    return false
  }
}

export default makeSSRRequest

// @/service/makeRequest.ts
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const config = getAPIRequestConfig()
    const {
      status,
      data: { value: response },
      execute
    } = await useFetch(url, {
      ...config,
      method,
      ...options,
      onResponseError: ({ response }) => {
        if (response.status === 401) {
          // do smt
        }
      }
    })

    return { status, response, execute }
  } catch (err: any) {
    // do smth

    return false
  }
}

export default makeSSRRequest

These changes should help ensure that your cookies and headers are properly forwarded in both development and production environments. For more information on this topic, you can refer to the following Nuxt documentation: - useRequestFetch - Passing Headers and Cookies These resources provide additional context on how to handle headers and cookies in Nuxt applications, especially in server-side rendering scenarios. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

unfortunately the solution you provided not working kapa.ai, thx for helping me tho , maybe a real human can provide solution or any clue ? it does not work @kapa.ai

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize that the previous suggestion did not resolve your issue. Let's try to troubleshoot this further. Based on the knowledge sources provided, there are a few more approaches we can consider to address the problem of passing cookies and headers in Nuxt, especially after deployment. 1. Using event.$fetch:
According to the Stack Overflow post, you can try using event.$fetch to ensure cookies are properly passed. Here's an example of how you might modify your code:

   const event = useRequestEvent();

   const makeSSRRequest = async (
     method: keyof APIMethodType,
     url: string,
     options?: APIOptions
   ): Promise<any> => {
     try {
       const response = await event.$fetch(url, {
         method,
         ...options,
         headers: useRequestHeaders(['cookie']),
         onResponse({ response }) {
           const cookies = response.headers.getSetCookie();
           if (cookies.length && event) {
             cookies.forEach((cookie) => {
               appendResponseHeader(event, 'set-cookie', cookie);
             });
           }
         },
       });

       return { status: response.status, response, execute: () => {} };
     } catch (err: any) {
       // Handle error
       return false;
     }
   };

   const event = useRequestEvent();

   const makeSSRRequest = async (
     method: keyof APIMethodType,
     url: string,
     options?: APIOptions
   ): Promise<any> => {
     try {
       const response = await event.$fetch(url, {
         method,
         ...options,
         headers: useRequestHeaders(['cookie']),
         onResponse({ response }) {
           const cookies = response.headers.getSetCookie();
           if (cookies.length && event) {
             cookies.forEach((cookie) => {
               appendResponseHeader(event, 'set-cookie', cookie);
             });
           }
         },
       });

       return { status: response.status, response, execute: () => {} };
     } catch (err: any) {
       // Handle error
       return false;
     }
   };

2. Using a custom fetch function:
The Nuxt documentation on data fetching suggests creating a custom fetch function to handle cookies. You could adapt this approach:

   import { appendResponseHeader } from 'h3'
   import type { H3Event } from 'h3'
export const fetchWithCookie = async (event: H3Event, url: string, options: any) => {
     const res = await $fetch.raw(url, options)
     const cookies = res.headers.getSetCookie()
     for (const cookie of cookies) {
       appendResponseHeader(event, 'set-cookie', cookie)
     }
     return res._data
   }

   // In your makeSSRRequest function:
   const event = useRequestEvent();
   const response = await fetchWithCookie(event, url, {
     method,
     ...options,
     headers: useRequestHeaders(['cookie'])
   });

   import { appendResponseHeader } from 'h3'
   import type { H3Event } from 'h3'
export const fetchWithCookie = async (event: H3Event, url: string, options: any) => {
     const res = await $fetch.raw(url, options)
     const cookies = res.headers.getSetCookie()
     for (const cookie of cookies) {
       appendResponseHeader(event, 'set-cookie', cookie)
     }
     return res._data
   }

   // In your makeSSRRequest function:
   const event = useRequestEvent();
   const response = await fetchWithCookie(event, url, {
     method,
     ...options,
     headers: useRequestHeaders(['cookie'])
   });

3. Ensure server-side execution:
Make sure that your getAPIRequestConfig function is actually running on the server when you expect it to. You can add a console.log to verify:

   const getAPIRequestConfig = (): RequestConfigType => {
     console.log('Running on server:', import.meta.server);
     // ... rest of your function
   }

   const getAPIRequestConfig = (): RequestConfigType => {
     console.log('Running on server:', import.meta.server);
     // ... rest of your function
   }

4. Check Nuxt configuration:
Ensure that your Nuxt configuration is set up correctly for server-side rendering. In your nuxt.config.ts, you should have:

   export default defineNuxtConfig({
     ssr: true,
     // other configurations...
   })

   export default defineNuxtConfig({
     ssr: true,
     // other configurations...
   })

If none of these solutions work, it might be helpful to add some debugging logs throughout your code to see exactly where the issue is occurring. Also, check your server logs for any errors that might provide more insight into the problem. Remember, the exact solution may depend on your specific server setup and Nuxt version. If you're still facing issues, you might want to create a minimal reproduction of the problem and seek help on the Nuxt GitHub issues page or the Nuxt Discord community. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

didn't work either @kapa.ai didn't work either

kapa.ai•2mo ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize that the previous suggestions did not resolve your issue. It's clear that this problem is more complex than initially thought. Without more specific information about how it "didn't work," it's challenging to provide a precise solution. However, I can offer some additional insights and a potential approach based on the latest information in our knowledge sources. A recent GitHub issue (#21940) highlights a problem with cookies not being immediately accessible when set using useCookie. This might be related to your issue, especially if you're setting cookies in plugins and trying to access them immediately in your pages or components. Given this information, here's an alternative approach you could try: 1. Instead of relying on useRequestHeaders or useCookie directly, create a custom composable that handles both client-side and server-side scenarios:

// composables/useCustomHeaders.ts
import { useCookie, useRequestHeaders } from '#app'

export function useCustomHeaders() {
  if (process.server) {
    // Server-side: use request headers
    return useRequestHeaders(['cookie'])
  } else {
    // Client-side: manually construct headers from cookies
    const cookies = useCookie('your-cookie-name').value
    return {
      cookie: cookies
    }
  }
}

// composables/useCustomHeaders.ts
import { useCookie, useRequestHeaders } from '#app'

export function useCustomHeaders() {
  if (process.server) {
    // Server-side: use request headers
    return useRequestHeaders(['cookie'])
  } else {
    // Client-side: manually construct headers from cookies
    const cookies = useCookie('your-cookie-name').value
    return {
      cookie: cookies
    }
  }
}

2. Modify your getAPIRequestConfig function to use this new composable:

// @/service/config.ts
import { useCustomHeaders } from '~/composables/useCustomHeaders'

const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const headers = useCustomHeaders()

  const API_BASE_URL = process.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = process.server
    ? config.authorization
    : config.public.authorization
return {
    baseURL: API_BASE_URL,
    headers: {
      ...headers,
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
    },
    server: true
  }
}

export default getAPIRequestConfig

// @/service/config.ts
import { useCustomHeaders } from '~/composables/useCustomHeaders'

const getAPIRequestConfig = (): RequestConfigType => {
  const config = useRuntimeConfig()
  const headers = useCustomHeaders()

  const API_BASE_URL = process.server
    ? config.baseUrl
    : config.public.baseUrl
  const AUTHORIZATION = process.server
    ? config.authorization
    : config.public.authorization
return {
    baseURL: API_BASE_URL,
    headers: {
      ...headers,
      Accept: 'application/json',
      'Content-Type': 'application/json; charset=utf-8',
      authorization: AUTHORIZATION,
    },
    server: true
  }
}

export default getAPIRequestConfig

3. In your makeSSRRequest function, use useAsyncData with a custom $fetch instance:

// @/service/makeRequest.ts
import { useAsyncData } from '#app'
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const config = getAPIRequestConfig()
    const { data, error } = await useAsyncData(
      url,
      () => $fetch(url, {
        ...config,
        method,
        ...options,
      }),
      {
        server: true,
        lazy: false,
      }
    )

    if (error.value) {
      throw error.value
    }

    return { status: 200, response: data.value, execute: () => {} }
  } catch (err: any) {
    // Handle error
    return false
  }
}

export default makeSSRRequest

// @/service/makeRequest.ts
import { useAsyncData } from '#app'
import getAPIRequestConfig from './config.ts'

const makeSSRRequest = async (
  method: keyof APIMethodType,
  url: string,
  options?: APIOptions
): Promise<any> => {
  try {
    const config = getAPIRequestConfig()
    const { data, error } = await useAsyncData(
      url,
      () => $fetch(url, {
        ...config,
        method,
        ...options,
      }),
      {
        server: true,
        lazy: false,
      }
    )

    if (error.value) {
      throw error.value
    }

    return { status: 200, response: data.value, execute: () => {} }
  } catch (err: any) {
    // Handle error
    return false
  }
}

export default makeSSRRequest

This approach attempts to address both server-side and client-side scenarios, and uses useAsyncData to ensure proper handling of asynchronous data fetching during server-side rendering. If this still doesn't work, it would be helpful to gather more specific information about the failure: 1. Are there any error messages in the console or server logs? 2. At what point exactly does the code fail (e.g., during SSR, on the client after hydration, etc.)? 3. What are the exact values of headers and cookies at different stages of your application lifecycle? With this additional information, you might want to consider opening a new issue on the Nuxt GitHub repository, providing a minimal reproduction of your problem. The Nuxt team or community might be able to provide more targeted assistance based on your specific use case and environment. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
