Curl request C# Unity3D-CodePudding

I have an API Curl request, that returns a link:

curl https://api.openai.com/v1/images/generations \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
  "prompt": "A cute baby sea otter",
  "n": 2,
  "size": "1024x1024"
}'

How can I request the link through Curl in my C# script in Unity Engine? Thanks!

This is what I have so far:

void Start () {
     StartCoroutine ("FillAndSend");
        }

public IEnumerator FillAndSend() {
 #Curl request here
}

As Dai stated out, you can use UnityWebRequest for this. You have few options to send it with. This is one way of doing it;

private const string YourApiKey = "3152-6969-1337";

void Start()
{
    var json = "{\"prompt\": \"A cute baby sea otter\",\"n\": 2,\"size\": \"1024x1024\"}";
    StartCoroutine(FillAndSend(json));
}

public IEnumerator FillAndSend(string json)
{
    using (var request = new UnityWebRequest("https://api.openai.com/v1/images/generations", "POST"))
    {
        request.SetRequestHeader("Content-Type", "application/json");
        request.SetRequestHeader("Authorization", $"Bearer {YourApiKey}");
        request.SetRequestHeader("Accept", " text/plain");

        request.uploadHandler = new UploadHandlerRaw(Encoding.UTF8.GetBytes(json));
        request.downloadHandler = new DownloadHandlerBuffer(); // You can also download directly PNG or other stuff easily. Check here for more information: https://docs.unity3d.com/Manual/UnityWebRequest-CreatingDownloadHandlers.html

        yield return request.SendWebRequest();

        if (request.isNetworkError || request.isHttpError) // Depending on your Unity version, it will tell that these are obsolote. You can try this: request.result != UnityWebRequest.Result.Success
        {
            Debug.LogError(request.error);
            yield break;
        }

        Debug.Log(request.downloadHandler.text);
        var response = request.downloadHandler.data; // Or you can directly get the raw binary data, if you need.
    }
}

You can also use UnityWebRequest.Post(string uri, string postData) method, or you can use WWWForm class to post with form, instead of JSON etc.

You can also create a model class for your data, then put prompt, n, and size properties in it. Afterwards, you can convert it to JSON with JsonUtility.ToJson(dalleRequest). Or if you want, you can take those values as parameters for the method, then create the string while sending the request.
