微信企业号开发,微信企业号开发—发送消息

开始回调模式后我们就要实现聊天功能了。平时使用 微信聊天可以发送文本消息、语音、图片、视频等,这里只实现了其中的一些功能和大家分享。

一、与微信企业号建立连接

 1、企业应用调用企业号提供的接口,管理或查询企业号后台所管理的资源、或给成员发送消息等,以下称主动调用模式

 2、企业号把用户发送的消息或用户触发的事件推送给企业应用,由企业应用处理,以下称回调模式

 3、用户在微信中阅读企业应用下发的H5页面,该页面可以调用微信提供的原生接口,使用微信开放的终端能力,以下称JSAPI模式

          这是微信企业号的开发文档中写的,但是我们一般使用前两种方式。

          其实主动调用和回调都是相对的,这是站在微信服务器的角度,微信服务器通过企业号给微信客户端发送消息是主动调用,微信客户端主动发送消息去调用微信服务器相对服务器来说就是被动调用(回调)。

 

二、主被动调用微信服务器处理的数据格式

1.主调:服务器向微信客户端发送json格式的数据,数据不需要加密

2.回调:微信客户端发送的消息需要AES加密,服务器接受的消息是xml格式

     这两条用一张图表示如下:

三、聊天原理图

微信企业号开发—发送消息

          首先微信客户端发送消息到服务器处理,数据以xml格式传输到第三方服务器后,第三方服务器再将数据转为json格式,传送给微信服务器,发送给客户端。

三、代码实现

    有了上面的原理基础,下面是代码部分

package com.hyd.smarthome.util.qq;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URL;
