微信企业号验证/发送/接收消息

1. 内网映射

由于微信企业号回调模式的URL尽支持域名方式访问,估需要注册花生壳,做一个内网穿透(需要花16块钱,购买一个免费版,购买之后,第二天才能添加上域名)

2. 微信企业号

注册微信企业号:https://qy.weixin.qq.com/ (选择团队,团队不需要认证)

通讯录:新建组织 - > 关注成员

企业号 -> 应用中心 -> 新建应用 -> 消息型应用 -> 模式选择(回调模式) -> 开启微信消息转发,
回调模式说明:http://qydev.weixin.qq.com/wiki/index.PHP?title=%E5%9B%9E%E8%B0%83%E6%A8%A1%E5%BC%8F
回调模式加密解密代码:http://qydev.weixin.qq.com/wiki/index.php?title=%E5%8A%A0%E8%A7%A3%E5%AF%86%E5%BA%93%E4%B8%8B%E8%BD%BD%E4%B8%8E%E8%BF%94%E5%9B%9E%E7%A0%81

如图1:

自定义菜单: 开发应用的请求路径如图2:

设置 -> 功能设置 -> 权限管理 -> 新建管理组 -> 应用权限( Secret )

3. 利用Jersey开发web Service服务

3.1 在类中定义token, 随机密码43位,公司corpId, secret

3.2 验证方法

/* 
* ------------使用示例一:验证回调URL---------------企业开启回调模式时,企业号会向验证url发送一个get请求 
* 假设点击验证时,企业收到类似请求: GET 
* /cgi-bin/wxpush?msg_signature=5c45ff5e21c57e6ad56bac8758b79b1d9ac89fd3 
* ×tamp 
* =1409659589&nonce=263014780&echostr=P9nAzCzyDtyTWESHep1vC5X9xho% 
* 2FqYX3Zpb4yKa9SKld1DsH3Iyt3tP3zNdtp%2B4RPcs8TgAE7OaBO%2BFZXvnaqQ%3D%3D 
* HTTP/1.1 Host: qy.weixin.qq.com 
* 
* 接收到该请求时,企业应 
* 1.解析出Get请求的参数,包括消息体签名(msg_signature),时间戳(timestamp),随机数字串(nonce 
* )以及公众平台推送过来的随机加密字符串(echostr), 这一步注意作URL解码。 2.验证消息体签名的正确性 3. 
* 解密出echostr原文,将原文当作Get请求的response,返回给公众平台 第2,3步可以用公众平台提供的库函数VerifyURL来实现。 
*/ 
/** 
* 回调URL,微信调用此方法进行验证 
* 
* @return 
*/ 
@GET 
@Path("station") 
public String verify() { 
String msgSignature = request.getParameter("msg_signature"); 
String timeStamp = request.getParameter("timestamp"); 
String nonce = request.getParameter("nonce"); 
System.out.println(timeStamp + " " + nonce); 
String echostr = request.getParameter("echostr"); 
String sEchoStr = null; 
try { 
sEchoStr = wxcpt.VerifyURL(msgSignature, timeStamp, nonce, echostr); 
} catch (Exception e) { 
e.printStackTrace();// 验证URL失败,错误原因请查看异常 
} 
return sEchoStr; 
}

3.3 接收用户信息,并解密

/* 
* ------------对用户回复的消息解密--------------- 
* 用户回复消息或者点击事件响应时,企业会收到回调消息,此消息是经过公众平台加密之后的密文以post形式发送给企业,密文格式请参考官方文档 
* 假设企业收到公众平台的回调消息如下: POST /cgi-bin/wxpush? 
* msg_signature=477715d11cdb4164915debcba66cb864d751f3e6 
* ×tamp=1409659813&nonce=1372623149 HTTP/1.1 Host: qy.weixin.qq.com

* <AgentID><![CDATA[218]]></AgentID> </xml> 
* 
* 企业收到post请求之后应该 
* 1.解析出url上的参数,包括消息体签名(msg_signature),时间戳(timestamp)以及随机数字串(nonce) 
* 2.验证消息体签名的正确性。 
* 3.将post请求的数据进行xml解析,并将<Encrypt>标签的内容进行解密,解密出来的明文即是用户回复消息的明文,明文格式请参考官方文档 
* 第2,3步可以用公众平台提供的库函数DecryptMsg来实现。
