c# .net对接企业微信小助手 接口请求时长预警

一、企业微信入参   

企业微信配置 机器人助手 : https://work.weixin.qq.com/api/doc/90000/90136/91770

    /// <summary>
    /// 企业微信机器人入参
    /// </summary>
    public class WebHookInput
    {
        /// <summary>
        /// 消息类型，此时固定为text
        /// </summary>
        public string msgtype
        {
            get
            {
                return "text";
            }
        }
        /// <summary>
        /// 文本内容
        /// </summary>
        public WebHookTextInput text { get; set; }
    }
    public class WebHookTextInput
    {

        /// <summary>
        /// 文本内容，最长不超过2048个字节，必须是utf8编码
        /// </summary>
        public string content { get; set; }
    }

 

二、post请求公共方法

        public static Toutput PostRequest<Toutput, Tinput>(string url, Tinput input)
        {
            Toutput output = default;
            if (string.IsNullOrEmpty(url)) return output;
            try
            {
                string inputParam = JsonConvert.SerializeObject(input);
                string result = GetPostUrl(url, inputParam);
                if (!string.IsNullOrEmpty(result))
                {
                    output = JsonConvert.DeserializeObject<Toutput>(result);
                }
            }
            catch (Exception ex)
            {
            }
            return output;
        }

//post
private static string GetPostUrl(string url, string postData, Dictionary<string, string> heardsDic = null)
        {
            string result = string.Empty;
            try
            {
                HttpWebRequest request = null;
                if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))
                {
                    request = WebRequest.Create(url) as HttpWebRequest;
                    ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
                    request.ProtocolVersion = HttpVersion.Version11;
                    // 这里设置了协议类型。
                    ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;// SecurityProtocolType.Tls1.2; 
                    request.KeepAlive = false;
                    ServicePointManager.CheckCertificateRevocationList = true;
                    ServicePointManager.DefaultConnectionLimit = 100;
                    ServicePointManager.Expect100Continue = false;
                }
                else
                {
                    request = (HttpWebRequest)WebRequest.Create(url);
                }

                request.Method = "POST";    //使用get方式发送数据
                request.ContentType = "application/json";
                request.Referer = null;
                request.AllowAutoRedirect = true;
                request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
                request.Accept = "*/*";
                #region 请求头数据
                if (heardsDic != null)
                {
                    foreach (var item in heardsDic)
                    {
                        SetHeaderValue(request.Headers, item.Key, item.Value);
                    }
                }
                #endregion 请求头数据
                byte[] data = Encoding.UTF8.GetBytes(postData);
                Stream newStream = request.GetRequestStream();
                newStream.Write(data, 0, data.Length);
                newStream.Close();

                //获取网页响应结果
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                Stream stream = response.GetResponseStream();
                using (StreamReader sr = new StreamReader(stream))
                {
                    result = sr.ReadToEnd();
                }
            }
            catch (Exception ex)
            {
            }
            return result;
        }
        private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            return true; //总是接受  
        }
        private static void SetHeaderValue(WebHeaderCollection header, string name, string value)
        {
            var property = typeof(WebHeaderCollection).GetProperty("InnerCollection", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
            if (property != null)
            {
                var collection = property.GetValue(header, null) as NameValueCollection;
                collection[name] = value;
            }
        }

三、发送企业微信消息封装

        /// <summary>
        /// 发送企业微信机器人消息
        /// </summary>
        /// <param name="param"></param>
        public void SendQYApiMessage(WebHookInput param)
        {
            var data =PostRequest<dynamic, WebHookInput>(“https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=693axxx6-7aoc-4bc4-97a0-0ec2sifa5aaa”, param);
        }

四、api接口的统一处理，告警超过1秒钟接口

    
 public class ExterApiFilter : ActionFilterAttribute
    {
      private Stopwatch _Stopwatch { get; set; }
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            base.OnActionExecuting(filterContext);
            _Stopwatch = new Stopwatch();
            _Stopwatch.Start();
        }

        /// <summary>
        /// 出接口
        /// </summary>
        /// <param name="filterContext"></param>
        protected override void OnActionExecuted(ActionExecutedContext filterContext)
        {
            base.OnActionExecuted(filterContext);
            _Stopwatch.Stop();
            int totalMill = (int)_Stopwatch.Elapsed.TotalMilliseconds;//接口处理时间：毫秒
            string logdata = $"Controller={filterContext.RouteData.Values["Controller"].ToString()},Action={filterContext.RouteData.Values["Action"].ToString()},接口处理时间：{totalMill}毫秒";
            #region 企业微信消息通知
            //写入发送消息
            duration = 10000;
            if (totalMill > duration)
            {
                string contents = $"接口请求响应超一秒," + logdata;
                SendQYApiMessage(WebHookInput() { text = new WebHookTextInput() { content = contents } });
            }
            #endregion 企业微信消息通知
        }
    }
