❔ how to make an API call

I have tried looking up tutorials but they ended up making me more confused. I want to take a string, generate an API call from that, then download the response. The API takes a URL-encoded string, and returns a link to a wav file, which I'd like to download. Is that possible? here's the link to the API I'd like to try using: https://tts.cyzon.us/ https://github.com/calzoneman/aeiou/blob/master/docs/usage-guidelines.md

someone sent me this, which is what they personally use to interact with a different API. Could this potentially be adapted for my use? I've tried understanding it but I can't...

public bool Execute()
    {
        string url = "URL here";
        
        var ttsRequest = (HttpWebRequest)WebRequest.Create(url);
        ttsRequest.ContentType = "application/json";
        ttsRequest.Method = "POST";
        
        JObject postJson = new JObject(); //"{text:\"This is a test message\", voice:\"en_us_001\"}";
                postJson["text"] = args["rawInput"].ToString(); //This is another test message.";
                postJson["voice"] = "en_male_m03_lobby";

        using (var client = new StreamWriter(ttsRequest.GetRequestStream())) 
            {
            client.Write(postJson.ToString());
            }

        var ttsResponse = (HttpWebResponse)ttsRequest.GetResponse();
        using (var streamReader = new StreamReader(ttsResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            JObject ttsData = JObject.Parse(result);

        Byte[] audioBytes = Convert.FromBase64String(ttsData.Value<string>("data"));
        File.WriteAllBytes("./tts.mp3", audioBytes);
        CPH.Wait(1000);
        CPH.PlaySound("./tts.mp3", 1.0f, true);
        }
        return true;
    }

public bool Execute()
    {
        string url = "URL here";
        
        var ttsRequest = (HttpWebRequest)WebRequest.Create(url);
        ttsRequest.ContentType = "application/json";
        ttsRequest.Method = "POST";
        
        JObject postJson = new JObject(); //"{text:\"This is a test message\", voice:\"en_us_001\"}";
                postJson["text"] = args["rawInput"].ToString(); //This is another test message.";
                postJson["voice"] = "en_male_m03_lobby";

        using (var client = new StreamWriter(ttsRequest.GetRequestStream())) 
            {
            client.Write(postJson.ToString());
            }

        var ttsResponse = (HttpWebResponse)ttsRequest.GetResponse();
        using (var streamReader = new StreamReader(ttsResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            JObject ttsData = JObject.Parse(result);

        Byte[] audioBytes = Convert.FromBase64String(ttsData.Value<string>("data"));
        File.WriteAllBytes("./tts.mp3", audioBytes);
        CPH.Wait(1000);
        CPH.PlaySound("./tts.mp3", 1.0f, true);
        }
        return true;
    }

if you know it downloads a wav file, why are you saving it as an mp3 lol

HttpClient client = new();
var response = await client.GetAsync(url);
var bytes = await response.Content.ReadAsBytesAsync();
// ...

HttpClient client = new();
var response = await client.GetAsync(url);
var bytes = await response.Content.ReadAsBytesAsync();
// ...

ero•2y ago

using on the first 2

Thinker•2y ago

afaik you shouldn't be using an HttpClient

ero•2y ago

you should that's why it implements idisposable so you can dispose it

Thinker•2y ago

anyway, that's how you should do it

ero•2y ago

the idea is to not create a new client every time if you do a lot of requests so you create one static long running client for the whole app

Pobiega•2y ago

Very bad idea to phrase it like this. MS docs repeatedly show that you should not be using HttpClient client = new(), as that pattern is never the correct one for httpclients. You should have a static one, or use the factory.

Chris TCCOP•2y ago

huh? just declaring it like this works? I thought you had to call a method or something

Pobiega•2y ago

there are method calls in that snippet

Thinker•2y ago

Well you still call a method

FusedQyou•2y ago

I think the reason why they advice against is is because it is bad performance wise do constantly make a new HttpClient, and you should reuse the same client. Because it does stuff in the background when you create one But don't quote me on that

Pobiega•2y ago

no, it has to do with connection pool exhaustion its not performance related

ero•2y ago

the usage guideline they sent says it's just a get?

which is why I'm asking for help lol... this is my first time doing anything related to API https://tts.cyzon.us/tts?text=hello+world like this

Pobiega•2y ago

well start out small, with a console app that just makes a request and shows the response

Chris TCCOP•2y ago

the link generates a wav file

Pobiega•2y ago

then go from there

Chris TCCOP•2y ago

I'm integrating this into another app - the C# code is just a script so idk how to even open a console

Pobiega•2y ago

start out small dont start with going for the end goal learn the components first

Chris TCCOP•2y ago

uh huh? so I make a standalone C# script first? or how does that work

Unknown User•2y ago

Message Not Public

Pobiega•2y ago

sure, a standalone console app.

Chris TCCOP•2y ago

I've only ever used C# as a scripting language so... for unity and now for an app called StreamerBot

Pobiega•2y ago

perhaps a good time to learn how to use it properly then?

Thinker•2y ago

Also for one, you cannot make a "standalone C# script"

Chris TCCOP•2y ago

uh... I wonder if I have the patience to learn it properly at this point tbh I've been using C# for years now in unity

Pobiega•2y ago

I mean, its not hard to make a blank console app its... 3-4 button clicks in VS

Chris TCCOP•2y ago

I use notepad

Pobiega•2y ago

stop using notepad

Thinker•2y ago

or like two console commands how tf do you get anything done...?

Chris TCCOP•2y ago

it works fine darkmode, autocomplete, that is sufficient for me

Thinker•2y ago

you'e been missing out if you've been using that for years

Chris TCCOP•2y ago

oh nah nah I use notepad for my Streamerbot scripting since the in-app editor stinks it doesn't even properly handle [tab] inputs

Thinker•2y ago

How fun is it to fix errors in Notepad?

Chris TCCOP•2y ago

I don't get any I mean - the errors I get are very minor ones like typos I use notepad to write the code then I copy paste it into the streamerbot editor

Thinker•2y ago

ah, write everything correctly the first time catsip

Chris TCCOP•2y ago

and that has a built-in compiler hell naw I make worse code than anyone I know

Thinker•2y ago

well you're only doing yourself a disservice by not using any kind of IDE, but you do you I guess

Chris TCCOP•2y ago

basically, C# is used as a scripting language with its own methods but if you import other stuff you can do stuff normal C# can like open new windows I got someone else's script which opens an admin window

Chris TCCOP•2y ago

message.txt

Chris TCCOP•2y ago

that's besides the point here - I'm just curious if I could make an API call, and if anyone would be able to help me learn the fundimentals because online tutorials ain't making it clear to me consider me baby at understanding this crap...

Pobiega•2y ago

well, if you make a new blank hello world console app as step 1 and then make THAT make the request... then you should be able to tweak it so your bot or whatever can do it

Chris TCCOP•2y ago

I don't think I have the time for this...

Thinker•2y ago

Thrn how do you expect to learn anything...? That's the absolute basics though, but it's kind of unclear what exactly you're looking for

Pobiega•2y ago

certainly feels like they want spoonfeeding

Chris TCCOP•2y ago

I mean... my way of learning so far was to try and figure out things as I go I was using arrays before I knew what a class was still kinda don't know what it is

Pobiega•2y ago

then go right ahead, you've been given all the information you need already

Chris TCCOP•2y ago

this?

Pobiega•2y ago

you need to make a HttpClient instance and use the methods on that thats the basics

Chris TCCOP•2y ago

https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient?view=net-8.0 I'll try and base my code off this I guess

HttpClient Class (System.Net.Http)

Provides a class for sending HTTP requests and receiving HTTP responses from a resource identified by a URI.

Thinker•2y ago

(and also maybe look into async and await a bit)

Chris TCCOP•2y ago

I'll give it a shot and get back with my attempt

ero•2y ago

i mean we also have to consider what version of .net this streamerbot thing supports right

Chris TCCOP•2y ago

I have absolutely no idea

Pobiega•2y ago

its gonna be .net 4.7 or later, so httpclient will still be the way to go

Thinker•2y ago

What are you even running your code through? You said it was some "Streamerbot" program?

Chris TCCOP•2y ago

yup

Thinker•2y ago

Do you have a link to this program/service?

Chris TCCOP•2y ago

Chris TCCOP•2y ago

usually the scripts I make are to clean up logic, because logic via the GUI sucks so it's just a simple if/else or switch script of around 40 lines or so then return true this is my first time doing something this complex here

sorry I linked the docs page

ero•2y ago

ero•2y ago

??? .Parse in one example, Convert in the other

Thinker•2y ago

that page reads like it itself doesn't know what it's talking about

Chris TCCOP•2y ago

I am confused myself at how the variables get converted from SB to C# variables but it's worked so far so...

ero•2y ago

no clue what it does, but it seems like an ambitious project by a single person?

Thinker•2y ago

What's SB?

ero•2y ago

so it's gonna be rough

Thinker•2y ago

Ah just StreamerBot

ero•2y ago

streamerbot lol

Thinker•2y ago

yea

Chris TCCOP•2y ago

yep I can understand that the C# implementation is very wonky but it's the most powerful thing that's available

Thinker•2y ago

The project unfortunately doesn't seem to be open-source

Chris TCCOP•2y ago

the GUI is super restrictive - if/else blocks can only either break out of the current action, or call another action meaning in code you have if then else, but in the GUI variant you must have 3 different methods that it jumps between so I always prefer code because it's cleaner afaik it's closed-source

Thinker•2y ago

oof

Chris TCCOP•2y ago

man... I'll just pray the guy inside the SB help channel is able to come to my rescue he's the one who made his own TTS via API system, and he's the one who shared the above code with me that's what he uses and it works

Thinker•2y ago

Also since I assume this is for Twitch or something, you can make Twitch bots in C# without this thing

Chris TCCOP•2y ago

I guess... but then you'd have to re-write it for youtube

Thinker•2y ago

yeah ig :/

Chris TCCOP•2y ago

also I'd have no idea how to listen to the api calls and stuff that twitch fires out and ofc they keep changing their API so keeping up with that is a pain, SB does that for me with app updates

Chris TCCOP•2y ago

this is what he told me about the API thing from streamerbot

Pobiega•2y ago

Execute is a sync method. ouch

Thinker•2y ago

oof

Pobiega•2y ago

big oof

Thinker•2y ago

ambitious project developed by a single person with mediocre docs, bad practices, and supposedly not very good code sounds about right

Chris TCCOP•2y ago

sounds about right but it's the most powerful but still user-friendly thing I could find going custom takes a lot of upkeep and knowhow, and is difficult to develop

Thinker•2y ago

yeah :/ I feel your pain

Chris TCCOP•2y ago

but most of em do their stuff like this

Chris TCCOP•2y ago

very few actually code in C# so I guess that's why the implementation might be wonky... not enough people use it to warrant making it proper, but just keep it up-to-date and functional enough wellp, someone from the SB discord helped me out and I got something that works still don't know how it works though, I don't understand most of what was written here:

            var task = GetAudioFile();
            task.Wait();

            var task = GetAudioFile();
            task.Wait();

should just be

await GetAudioFile();

await GetAudioFile();

and the Execute method should be async Task<bool>

i don't think that's possible unfortunately
