.net开发微信公众平台
一、說明：公眾平臺信息接口為開發者提供了一種新的消息處理方式，只有申請成為開發者后，你才能使用公眾平臺的開發功能，在這里你需要填寫一個URL和一個Token，這兩項信息也需要你擁有自己的服務器（外網服務器）資源，其中的Token可由開發者任意填寫，URL即是接口配置信息的鏈接地址，在本文中我采用的是創建一個簡易網站的方式，在其中的一個頁面的后臺程序中配置相關的接口信息，然后發布到外網服務器上，最后可以訪問到這個頁面的鏈接地址即是這里應該填寫的URL。

二、接口配置過程：
1.網址接入-校驗簽名：
??? const string Token = "aka";//定義一個局部變量不可以被修改，這里定義的變量要與接口配置信息中填寫的Token一致
??? protected void Page_Load(object sender, EventArgs e)
??? {
??????? string postStr = "";
??????? Valid();//校驗簽名,當填入的信息提交之后頁面有提示“你已成功成為公眾平臺開發者，可以使用公眾平臺的開發功能”這個的時候，接下來你就需要注釋掉這個校驗的方法，使得后面的消息回復得以正常運作
??????? if (Request.HttpMethod.ToLower() == "post")//當普通微信用戶向公眾賬號發消息時，微信服務器將POST該消息到填寫的URL上
??????? {
??????????? postStr = PostInput();
??????????? if (string.IsNullOrEmpty(postStr) == false)
??????????? {
??????????????? //WriteLog(postStr,Server);//計入日記
??????????????? ResponseMsg(postStr);
??????????? }
??????? }
??? }
??? private void Valid()
??? {
??????? string echoStr = Request.QueryString["echoStr"].ToString();
??????? if (CheckSignature())
??????? {
??????????? if (!string.IsNullOrEmpty(echoStr))
??????????? {
??????????????? Response.Write(echoStr);
??????????????? Response.End();
