C#手写http监听

在应用程序中有时需要一个http接口来与第三方通讯。

下面是个简单的代码示例：

 public async void StartHttpListener(string url) 
{
   HttpListener httpListener=new HttpListener();
   httpListener.Prefixes.Add(url);
   httpListener.Start();
   while(true)
   {
    var requestinfo=await httpListener.GetContextAsync();
      if(requestinfo.Request.HttpMethod=="POST")
       {
         var requestEntity=await requestinfo.ReadFromJsonAsync<RequestEntityClass>();//json转为对象
        if(requestEntity!=null)
          {

           }
          else
           {
             await requestinfo.WriteAsJsonAsync(new ResponseInfo{ code="2",message="error"});
           }
       }
     request.Response.ContentType = "application/json";
                request.Response.ContentEncoding = Encoding.UTF8;
                request.Response.OutputStream.Flush();
                request.Response.OutputStream.Close();
                request.Response.OutputStream.Dispose();
    }
 }
