From HttpClient, can I save/copy the request to share with someone?

Is there a way to copy raw request details? For example, I'm looking for a similar output like: - in Bruno you right-click a request and click "Generate Code" - in Postman you click the "view code" button on a request Thanks

No, HttpClient is neither Postman nor Bruno It's used to make HTTP requests to fetch or send some data Not to share those requests in a human-readable or reproductible format You can maybe code this functionality yourself, if you want

i know HttpClient is neither Postman or Bruno, it was an example of what data I want

The only way I can think of is to construct the HttpRequestMessage and use that to find info before using HttpClient to send https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httprequestmessage?view=net-8.0

HttpRequestMessage Class (System.Net.Http)

Represents a HTTP request message.

I believe HttpClient disposes the request on send, so make sure you pull out info before you do that

yeah ok, I thought maybe I was overlooking some helpful inbuilt function like .DumpRequest() or something

that gets the response, not the request

cowOP•9mo ago

oh woops didnt read it close enough

lycian•9mo ago

but you basically can do the same with HttpRequestMessage

cowOP•9mo ago

ill give it a try, thanks tbh i really thought there would be a native function

Angius•9mo ago

You're the first person I heard of that would use it lol

cowOP•9mo ago

really? i've had plenty of requests from support teams and such to share the raw request sometimes i use wireshark or fiddler to get it, but that's an annoying extra step I was trying to reduce

you can intercept the request before it goes down the pipeline with a DelegatingHandler it will give you headers, verb, version, url, body etc something like this:

HttpClient client = new HttpClient(new LoggingHandler(new HttpClientHandler()));

//ADD CODE BELOW - Use client



//ADD CODE ABOVE - Use client

public class LoggingHandler : DelegatingHandler
{
    public LoggingHandler(HttpMessageHandler innerHandler) : base(innerHandler)
    {
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        Console.WriteLine("Request:");
        Console.WriteLine(request.ToString());
        if (request.Content != null)
        {
            Console.WriteLine(await request.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        Console.WriteLine("Response:");
        Console.WriteLine(response.ToString());
        if (response.Content != null)
        {
            Console.WriteLine(await response.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        return response;
    }
}

HttpClient client = new HttpClient(new LoggingHandler(new HttpClientHandler()));

//ADD CODE BELOW - Use client



//ADD CODE ABOVE - Use client

public class LoggingHandler : DelegatingHandler
{
    public LoggingHandler(HttpMessageHandler innerHandler) : base(innerHandler)
    {
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        Console.WriteLine("Request:");
        Console.WriteLine(request.ToString());
        if (request.Content != null)
        {
            Console.WriteLine(await request.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        Console.WriteLine("Response:");
        Console.WriteLine(response.ToString());
        if (response.Content != null)
        {
            Console.WriteLine(await response.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        return response;
    }
}
