unitywebrequest 有哪些用法

UnityWebRequest是Unity中用于进行网络请求的类，它提供了一些常用的方法和属性来发送和处理网络请求。下面是一些UnityWebRequest的常见用法：

1. 发送GET请求：

string url = "https://www.example.com/api/data";
UnityWebRequest request = UnityWebRequest.Get(url);
yield return request.SendWebRequest();

if (request.result != UnityWebRequest.Result.Success) {
    Debug.Log(request.error);
} else {
    string responseText = request.downloadHandler.text;
    // 处理响应数据
}

2. 发送POST请求：

string url = "https://www.example.com/api/data";
List<IMultipartFormSection> formData = new List<IMultipartFormSection>();
formData.Add(new MultipartFormDataSection("key1", "value1"));
formData.Add(new MultipartFormDataSection("key2", "value2"));

UnityWebRequest request = UnityWebRequest.Post(url, formData);
yield return request.SendWebRequest();

if (request.result != UnityWebRequest.Result.Success) {
    Debug.Log(request.error);
} else {
    string responseText = request.downloadHandler.text;
    // 处理响应数据
}

3. 设置请求头信息：

string url = "https://www.example.com/api/data";
UnityWebRequest request = UnityWebRequest.Get(url);
request.SetRequestHeader("Authorization", "Bearer token123");
request.SetRequestHeader("Content-Type", "application/json");

yield return request.SendWebRequest();

// 处理响应数据

4. 下载文件：

string url = "https://www.example.com/images/image.jpg";
UnityWebRequest request = UnityWebRequest.Get(url);
yield return request.SendWebRequest();

if (request.result != UnityWebRequest.Result.Success) {
    Debug.Log(request.error);
} else {
    byte[] fileData = request.downloadHandler.data;
    // 保存文件数据
}

这些只是UnityWebRequest的一些常见用法，还有其他更多的方法和属性可以根据需求进行使用。详细的用法可以参考Unity官方文档或者其他网络教程。
