Unity开发Http post请求
public void LuaPost(string url, Action<object,object,object> callback, string fields = null, bool isEncodFields = true, string header = null, int timeout = 5){ StartCoroutine(_Post(url, delegate(long code, HttpHelperRequests requests, HttpHelperResponses rsponse) { callback?.Invoke(code, requests, rsponse); }, fields, isEncodFields, header, timeout));}IEnumerator _Post(string url, HttpHelperPostGetCallbacks callback, string fields, bool isEncodFields, string header, int timeout){ using (UnityWebRequest webRequest = UnityWebRequest.Post(url, fields)) { webRequest.timeout = timeout; //设置请求头根据实际需求来 webRequest.SetRequestHeader("Authorization", ""); //处理请求头设置 if (!string.IsNullOrEmpty(header)) { JObject json = (JObject)Newtonsoft.Json.JsonConvert.DeserializeObject(header); if (json != null) { foreach (KeyValuePair<string, JToken> item in json) { webRequest.SetRequestHeader(item.Key, item.Value.Value<string>()); } } } //不自动encode if (!string.IsNullOrEmpty(fields) && !isEncodFields) { byte[] bodyRaw = System.Text.Encoding.UTF8.GetBytes(fields); if (bodyRaw != null) webRequest.uploadHandler = new UploadHandlerRaw(bodyRaw); } //开始与远程服务器通信 //等待通行完成 yield return webRequest.SendWebRequest(); //组装请求信息 HttpHelperRequests requests = new HttpHelperRequests(); requests.url = url; requests.fileds = fields; requests.headers = header; //组装返回信息 HttpHelperResponses responses = new HttpHelperResponses(); responses.code = webRequest.responseCode; responses.message = webRequest.error; responses.headers = webRequest.GetResponseHeaders(); responses.text = webRequest.downloadHandler.text; responses.bytes = webRequest.downloadHandler.data; //调用委托 callback?.Invoke(webRequest.responseCode, requests, responses); //结束 处理占用资源 //尽快停止UnityWebRequest webRequest.Abort(); //默认值是true，调用该方法不需要设置Dispose()，Unity就会自动在完成后调用Dispose()释放资源。 webRequest.disposeDownloadHandlerOnDispose = true; //不再使用此UnityWebRequest，并应清理它正在使用的任何资源 webRequest.Dispose(); }}<hr>注：请求体不使用encode，重新赋值webRequest.uploadHandler即可。有的服务器计算sing时可能用非encode的串计算
