asp.net微信開發(fā)（開發(fā)者接入)
更新時間：2015年11月12日 11:57:45 作者：將哥
這篇文章主要介紹了asp.net微信開發(fā)中有關(guān)開發(fā)者接入的相關(guān)內(nèi)容，需要的朋友可以參考下
先上圖，看一看需要進行哪些項目的操作：
在項目的根目錄或者特定的文件夾內(nèi)，創(chuàng)建一個ashx文件(一般處理程序文件)，如圖
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string postString = string.Empty;
if (HttpContext.Current.Request.HttpMethod.ToUpper() == "POST")
{
using (Stream stream = HttpContext.Current.Request.InputStream)
{
Byte[] postBytes = new Byte[stream.Length];
stream.Read(postBytes, 0, (Int32)stream.Length);
postString = Encoding.UTF8.GetString(postBytes);
}
if (!string.IsNullOrEmpty(postString))
{
ResponseXML(postString);//返回給微信用戶信息
}
