1.获取参数，指定文件绝对路径

private string getCommand()        {            return string.Format(" -F media=@\"{0}\" \"https://api.weixin.qq.com/cgi-bin/media/upload?access_token={1}&type=images\""                , this.FileName                , this.config.Access_Token                );        }

2.执行命令

/// 
        /// 运行cmd命令        /// 不显示命令窗口        /// 
        /// 指定应用程序的完整路径        /// 执行命令行参数       public static string RunCmd2(string cmdStr)        {            try            {                using (Process myPro = new Process())                {                    //指定绝对路径                    // myPro.StartInfo.FileName = @"I:\AppSolution\curl_pkg\curl-7.57.0-win64-mingw\bin\curl.exe";                    //使用环境变量路径                    string enPath = Environment.GetEnvironmentVariable("CURL_HOME");                    LogOperate.Write("当前命令的环境变量："+enPath);                    myPro.StartInfo.FileName = enPath + @"\curl.exe";                    myPro.StartInfo.UseShellExecute = false;                    myPro.StartInfo.RedirectStandardInput = true;                    myPro.StartInfo.RedirectStandardOutput = true;                    myPro.StartInfo.RedirectStandardError = true;                    myPro.StartInfo.CreateNoWindow = true;                    myPro.StartInfo.Arguments = cmdStr; //指定参数                    myPro.Start();                    myPro.StandardInput.AutoFlush = true;                    //获取cmd窗口的输出信息                    string output = myPro.StandardOutput.ReadToEnd();                    myPro.WaitForExit();                    myPro.Close();                    return output;                }            }            catch (Exception ex)            {                return ex.Message;            }        }

3.解析curl相应结果

#region 远程调用        /// 
        /// 上传图片返回图片id        /// 
        ///         /// 
           public string PostImage(string filename)        {            try            {                this.FileName = AppDomain.CurrentDomain.BaseDirectory + "data/" + filename;                string command = getCommand();                LogOperate.Write("PostImage:" + command);                //执行命令获取mediaid                string backdata = RunCmd2(command);                LogOperate.Write("backdata:" + backdata);                JObject obj = JObject.FromObject(backdata);                JToken media_id = obj.SelectToken("media_id");                if (media_id == null)                    throw new Exception($"获取media_id失败，" + backdata);                return media_id.ToString();            }            catch (Exception ex)            {                LogOperate.Write("上传素材出错：" + ex.Message + "|" + ex.StackTrace);            }            return string.Empty;        }        #endregion
