项目问题接触了写webSocket的一些东西,先记录下来(功能是pc端添加一条数据然后微应用端(h5)接受数据,需要在pc端打开websocket服务器把参数传过去,然后微应用端链接webSocket服务器后服务器再把参数传给微应用端)

这里是pc端添加数据后执行的打开webSocket服务器的代码

using System.Transactions;
//using 挺多需要哪些用哪些吧

            Thread ta = new Thread(new ThreadStart(delegate ()
            {
                try
                {

                    HF.Cloud.BLL.Common.Logger.Error("webSocket调试start!");
                    //string rootPath = @"D:\dingding\bin\HF.Clound.DingDingForm.exe";
                    string rootPath = @"D:\易维客\AssetCloudSolutionV1.5\HF.Clound.DingDingForm\bin\Release\HF.Clound.DingDingForm.exe";
                    string fileName = rootPath;
                    Process pro = new Process();
                    //pro.StartInfo.CreateNoWindow = true;
                    pro.StartInfo.UseShellExecute = true;//true显示应用窗口,false不显示窗口
                    pro.StartInfo.FileName = fileName;
                    pro.StartInfo.Arguments = "121 dfs";//用空格来分割参数

                    HF.Cloud.BLL.Common.Logger.Error("webSocket调试:" + pro.StartInfo.Arguments);

                    pro.Start();
                    pro.WaitForExit();//一直打开不会退出
                    HF.Cloud.BLL.Common.Logger.Error("webSocket调试结束");
                }
                catch (Exception ex)
                {
                    throw ex;
                }


            }));
            ta.Start();


这里是webSecket服务器端的代码,通过pro.Start();可以打开此exe服务端应用
