企业微信回调事件java工具类 企业微信接口调用

企业微信回调接口开发

1、从企业微信api获取加解密方法

地址：企业微信api

注意事项：这里肯定会出现下面说的异常，按照说明下载jar替换jdk原来的jar就能解决问题，如果不行那就重启电脑。

2、企业微信操作

这里首先需要网页登录企业微信，并且要以管理员身份登录，因为下面的操作都需要管理员授权操作。

3、本地代码

1、首先要获取corpid，参照下面的操作即可；

2、配置自定义配置：

wechat:
   sCorpID: ww92e8a0cb0975b937
   sToken: Qq4dP7M
   sEncodingAESKey: LJ81CzFpS2xUPLtSOyRxK0OakUIHwn9mvHjEIVAD6sp

3、引入微信加解密方法

这里把前面下载的直接放到自己的项目下面就行；

4、本地接收接口

这里需要两个接口，接口地址是一样的，一个get一个post；get用于验证回调是否有效；post才是微信回调用的；

直接上代码：

5、配置回调地址

这里填入你自己的毁掉地址就行，前提你的地址要实现外网可以访问。

token和key和你在配置文件里的一致就行，点击保存，看到返回配置成功就OK了。

到此完美解决企业微信回调接口开发。欢迎大家评论留言！
