HttpLink

HttpLink is a builder-pattern HTTP client wrapping Unity's UnityWebRequest. It handles GET/POST requests, JSON deserialization, custom headers, and timeouts concisely.

GET Request

var result = await new HttpLink.Builder()
    .SetUrl("https://api.example.com/users/1")
    .AddHeader("Authorization", "Bearer token123")
    .SetTimeout(10)
    .GetAsync<UserData>();

if (result != null)
    Debug.Log($"User: {result.Name}");

POST Request

string json = JsonConvert.SerializeObject(new LoginRequest { UserId = "abc", Password = "pw" });

bool success = await new HttpLink.Builder()
    .SetUrl("https://api.example.com/login")
    .SetJsonBody(json)
    .PostAsync();

Debug.Log(success ? "Login succeeded" : "Login failed");

Raw Send (SendAsync)

Use Build().SendAsync() to inspect the response directly.

var link = await new HttpLink.Builder()
    .SetUrl("https://api.example.com/data")
    .SetMethod(UnityWebRequest.kHttpVerbGET)
    .Build()
    .SendAsync();

if (link.Success)
    Debug.Log(link.ReceiveDataString);
