asp.net开发微信验证消息的实例详解
验证消息的真实性
在MVC Controller所在项目中添加过滤器,在过滤器中重写
public override void OnActionExecuting(ActionExecutingContext filterContext)方法
新建数据模型
注:服务器接收消息时,不再是signature而是msg_signature
微信服务器推送消息到服务器的HTTP请求报文示例
POST /cgi-bin/wxpush? msg_signature=477715d11cdb4164915debcba66cb864d751f3e6×tamp=1409659813&nonce=1372623149 HTTP/1.1
Host: qy.weixin.qq.com
方法重写,实现对消息的验证
调用微信接入时验证的方法,不过参数需要小改动一下,采用新建的数据模型
在Action方法或在Controller上添加过滤器属性
代码示例
Model/// <summary>/// 微信推送消息模型/// </summary>public class WeChatMsgRequestModel{public string timestamp { get; set; }public string nonce { get; set; }public string msg_signature { get; set; }}Filterpublic class WeChatRequestValidAttribute : ActionFilterAttribute{private const string Token = "StupidMe";public override void OnActionExecuting(ActionExecutingContext filterContext){//参数适配Model.FormatModel.WeChatMsgRequestModel model = new Model.FormatModel.WeChatMsgRequestModel() { nonce= filterContext.HttpContext.Request.QueryString["nonce"],msg_signature= filterContext.HttpContext.Request.QueryString["msg_signature"],timestamp= filterContext.HttpContext.Request.QueryString["timestamp"] };//验证if (CheckSignature(model)){base.OnActionExecuting(filterContext);}}private bool CheckSignature(Model.FormatModel.WeChatMsgRequestModel model){string signature, timestamp, nonce, tempStr;//获取请求来的参数signature = model.msg_signature;timestamp = model.timestamp;nonce = model.nonce;//创建数组,将 Token, timestamp, nonce 三个参数加入数组string[] array = { Token, timestamp, nonce };//进行排序Array.Sort(array);//拼接为一个字符串tempStr = String.Join("", array);//对字符串进行 SHA1加密tempStr = FormsAuthentication.HashPasswordForStoringInConfigFile(tempStr, "SHA1").ToLower();//判断signature 是否正确if (tempStr.Equals(signature)){return true;}else{return false;}}}Controller Code/// <summary>/// 日志助手/// </summary>private static Common.LogHelper logger = new Common.LogHelper(typeof(HomeController));[Filters.WeChatRequestValid]public void Valid(Model.FormatModel.WeChatMsgRequestModel model){if (ModelState.IsValid){try{//判断是否是POST请求if (HttpContext.Request.HttpMethod.ToUpper() == "POST"){//从请求的数据流中获取请求信息using (Stream stream = HttpContext.Request.InputStream){byte[] postBytes = new byte[stream.Length];stream.Read(postBytes, 0, (int)stream.Length);string postString = System.Text.Encoding.UTF8.GetString(postBytes);Handle(postString,model);}}}catch (Exception ex){logger.Error("发生异常,异常信息:" + ex.Message + ex.StackTrace);}}}以上就是asp.net开发微信验证消息的实例详解的详细内容,更多请关注小潘博客其它相关文章!
