How to Efficiently Handle HTTP GET and POST Requests in Unity with C#?

Efficiently handle HTTP GET and POST requests in Unity C#

In Unity, making HTTP requests is a common task for various web-based applications. This article explores how to efficiently send HTTP GET and POST requests using C# in Unity.

GET request

To perform a GET request, use Unity’s UnityWebRequest as follows:

IEnumerator getRequest(string uri)
{
    UnityWebRequest uwr = UnityWebRequest.Get(uri);
    yield return uwr.SendWebRequest();

    if (uwr.isNetworkError)
    {
        // 处理网络错误
    }
    else
    {
        // 处理响应
    }
}

POST request

Form data POST

To send form data in a POST request, create an instance of WWWForm:

WWWForm form = new WWWForm();
form.AddField("field1", "value1");
...
UnityWebRequest uwr = UnityWebRequest.Post(url, form);

JSON POST

To send JSON data, set the Content-Type header and use UploadHandlerRaw:

var uwr = new UnityWebRequest(url, "POST");
byte[] jsonToSend = Encoding.UTF8.GetBytes(json);
uwr.uploadHandler = new UploadHandlerRaw(jsonToSend);
uwr.SetRequestHeader("Content-Type", "application/json");

Multipart/Form Data POST

For multipart data, use MultipartFormDataSection and MultipartFormFileSection:

List<IMultipartFormSection> formData = new List<IMultipartFormSection>();
formData.Add(new MultipartFormDataSection("field1=value1"));
formData.Add(new MultipartFormFileSection("file", "file.txt"));
UnityWebRequest uwr = UnityWebRequest.Post(url, formData);

Other HTTP methods

Similarly, for PUT, DELETE and other methods, use UnityWebRequest.Put, UnityWebRequest.Delete, etc.
