.net 微信接口（如何使用微信接口--做过的请进）

[段传涛]

想做一个程序通过微信发信息。
有人做过吗？是怎么实现的。
-------------------------------------------------------------------------------------------------------
我找的参考代码，有人知道实现不步骤吗？

[微工程]

楼主的代码是用来接收的，不是发送的。
如果想通过电脑发出信息到对方手机的微信上。那么需要知道微信的通信协议和地址。否则连待接收手机的地址都不能知道，实现不了发送。另外微信的协议是加密的。
需要知道这些

不管是消息推送还是消息回复都应该是xml把，我也没做过

关注中，希望这个帖子有个好的结果！！

[大渣吼吾系渣渣辉]

前几天做这个了， 整体流程是： 1.用户发消息给微信服务器》2.微信服务器收到用户消息》3.微信服务器把消息发给你》4.你解析消息》5.返回给微信服务器》6.微信服务器发消息给用户

[大渣吼吾系渣渣辉]

先把说明文档看一遍，其实也不是很难了 你发送给微信服务器的内容基本上都是xml格式的 当用户发送消息给微信，微信会以xml格式把内容发给你，xml里面包裹了发送信息用户的id（fromuser）、接受者id、消息类型等信息，你接受到消息之后根据“消息类型”来回复，其实你可以先统一回复成“文本消息”的内容（也就是说不管用户给你发什么，你都回复成文本，至于回复的格式，看文档）

例

        /// <summary>
        /// 处理文本消息
        /// </summary>
        /// <param name="xml"></param>
        /// <returns></returns>
        private static string DoTextMsg(XmlDocument xml)
        {
            //微信服务器发过来xml
            //TODO 取出内容
            string touser = xml.SelectSingleNode("xml/ToUserName").InnerText;
            string fromuser = xml.SelectSingleNode("xml/FromUserName").InnerText;
 
            //下面就是如何处理xml
            xml.SelectSingleNode("xml/ToUserName").InnerText = fromuser;//设置接受消息的用户
            xml.SelectSingleNode("xml/FromUserName").InnerText = touser;//消息来自谁
            xml.SelectSingleNode("xml/Content").InnerText = "这是回复的内容";//这里是你回复的内容，字符串的怎么写都可以
 
            return xml.OuterXml;//以字符串形式返回
        }
