C#代码中，实现Http/Https 中的POST请求，可以有很多种方式，下面就梳理下我常用的几种方式，给大家借鉴

1.首先是基础的参数

	//请求地址string url = $"https:/pczd.com/api/swj/auto/buildSln";//请求头Dictionary<string, string> header = new Dictionary<string, string>();//添加Tokenheader.Add("Authorization", "Token");//请求参数  这边使用JSONJToken param = new JObject();param["SlnCode"] = "Number01";param["SlnName"] = "一号上位机";param["SlnFramework"] = "Net461";//添加数组JArray jArray = JArray.FromObject(codeList);param["list"] = jArray;//得到JSON字符串string data = param.ToString();

2.使用RestClient  

使用RestClient  需要在项目中使用Nuget 引用 RestSharp包

//创建请求对象var client = new RestClient(url); //创建Requestvar request = new RestRequest();//设置请求类型 POSTrequest.Method = Method.Post;//添加请求头request.AddHeader("Authorization", "Token");request.AddHeader("Content-Type", "application/json");//添加请求体request.AddParameter("application/json", data, ParameterType.RequestBody);//发送请求var response = client.Execute(request);if(response.StatusCode==HttpStatusCode.OK){var result = string.Empty;//接收返回内容result = response.Content;//JSON 解析var resJson = JToken.Parse(result);var code = Convert.ToInt32(resJson["code"]);var msg = Convert.ToString(resJson["msg"]);if (code != 200){return new BaseResult(false, $"[{code}]{msg}");}return BaseResult.Successed;}else{return new BaseResult(false, $"[{response.StatusCode}]");}

3.使用封装库  

我自己封装的，需要Nuget引用 LS.Helper

做好一些方法的封装，在使用的过程中就能简化很多代码，和减少很多工作量

	//直接传请求头参数 和 请求JToken对象，再给个编码var resJson= LS.Helper.HttpJsonHelper.HttpPostRequest(url, header, param,dataEncoding);//返回的JToken对象，直接使用名称获取值var code = Convert.ToInt32(resJson["code"]);var msg = Convert.ToString(resJson["msg"]);if (code != 200){GlobalData.ProcessCtrl.AddOtherAlarm("MES041", $"绑定盒子码[{packingQrcode}]发生异常,接口返回信息【[{code}]{msg}】");return new BaseResult(false, $"[{code}]{msg}");}return BaseResult.Successed;

4.使用微软原生库进行请求

var request = (HttpWebRequest)WebRequest.Create(url);request.Method = "POST";              request.ContentType = "application/json";request.ContentLength = data.Length;request.Headers.Add("Authorization", token.Token);request.Headers.Add("Accept-Encoding", "gzip, deflate, br");//将请求体内容写入流中byte[] paramJsonBytes;paramJsonBytes = Encoding.ASCII.GetBytes(data);request.ContentLength = paramJsonBytes.Length;Stream writer = request.GetRequestStream();writer.Write(paramJsonBytes, 0, paramJsonBytes.Length);//发送请求var response = (HttpWebResponse)request.GetResponse();if (response.StatusCode == HttpStatusCode.OK){var result = string.Empty;//使用流接收数据using (var streamReader = new StreamReader(response.GetResponseStream())){//读取流中的内容result = streamReader.ReadToEnd();//JSON序列化，返回JToken对象var resJson = JToken.Parse(result);var code = Convert.ToInt32(resJson["code"]);var msg = Convert.ToString(resJson["msg"]);if (code != 200){GlobalData.ProcessCtrl.AddOtherAlarm("MES041", $"绑定盒子码[{packingQrcode}]发生异常,接口返回信息【[{code}]{msg}】");return new BaseResult(false, $"[{code}]{msg}");}return BaseResult.Successed;}}else{return new BaseResult(false, $"[{response.StatusCode}]");}

5.使用HttpClient进行请求

using (var httpClient = new HttpClient()){//添加请求头httpClient.DefaultRequestHeaders.Add("Authorization", token.Token);//创建请求体对象var content = new StringContent(data, dataEncoding, "application/json");     //发情POST请求  此处为异步请求var task = httpClient.PostAsync(url, content);//同步方法中需要等待task.Wait();var response = task.Result;if (response.IsSuccessStatusCode){//获取返回结果，一样是异步方法var res_task = response.Content.ReadAsStringAsync();//同步方法中需要等待res_task.Wait();var result = res_task.Result;//JSON序列化JToken resJson = JObject.Parse(result);var code = Convert.ToInt32(resJson["code"]);var msg = Convert.ToString(resJson["msg"]);if (code != 200){GlobalData.ProcessCtrl.AddOtherAlarm("MES041", $"绑定盒子码[{packingQrcode}]发生异常,接口返回信息【[{code}]{msg}】");return new BaseResult(false, $"[{code}]{msg}");}return BaseResult.Successed;}else{return new BaseResult(false, $"[{response.StatusCode}]");}}
