unity使用HTTP中post方式哀求调用接口

 unity自带的UnityWebRequest提供了构成 HTTP 哀求和处置惩罚 HTTP 响应。
构造函数：
public UnityWebRequest();
public UnityWebRequest(Uri uri);
public UnityWebRequest(string url);
public UnityWebRequest(Uri uri, string method);
public UnityWebRequest(string url, string method);
public UnityWebRequest(string url, string method, DownloadHandler downloadHandler, UploadHandler uploadHandler);
public UnityWebRequest(Uri uri, string method, DownloadHandler downloadHandler, UploadHandler uploadHandler);
简朴的例子：

1. using FF = StarEngineTec.Generic.FormatFunc;
3. string url="";//请求地址
4. string jsonData="";//需要上传的json数据
6. IEnumerator UploadPost()
7. {
8.     UnityWebRequest uwr = new UnityWebRequest(url, "POST");
9.     uwr.uploadHandler = new UploadHandlerRaw(FF.StringToBytes(jsonData));
10.     uwr.downloadHandler = new DownloadHandlerBuffer();
12.     //如果有请求头，根据具体字段要求设置
13.     uwr.SetRequestHeader("Content-Type", "application/json");
14.     uwr.SetRequestHeader("app-version", "V1");
16.     yield return uwr.SendWebRequest();
18.     if (uwr.isHttpError || uwr.isNetworkError)
19.     {
20.          Debug.LogError("Login Error: " + uwr.error);
21.     }
22. }

复制代码

其他常用方法：
public static UnityWebRequest Post(Uri uri, Dictionary<string, string> formFields);
public static UnityWebRequest Post(Uri uri, WWWForm formData);
public static UnityWebRequest Post(string uri, WWWForm formData);
public static UnityWebRequest Post(Uri uri, string postData);
public static UnityWebRequest Post(string uri, string postData);
public static UnityWebRequest Post(string uri, Dictionary<string, string> formFields);

1. IEnumerator Upload(string str)
2. {
3.        WWWForm form = new WWWForm();
4.        form.AddField("data", str);
6.        UnityWebRequest webRequest = UnityWebRequest.Post(url, form);
8.        yield return webRequest.SendWebRequest();
10.        if (webRequest.isHttpError || webRequest.isNetworkError)
11.            Debug.Log(webRequest.error);
12.        else      
13.            Debug.Log(webRequest.downloadHandler.text);
14. }

复制代码

一样平常上传完数据会返回条消息，可以根据code值判断乐成与否，以及哀求失败的缘故起因
