用Java代码取一个网名 java昵称( 二 )


;secret=SECRETjs_code=JSCODEgrant_type=authorization_code
appid是你小程序的appid,secret是你小程序的appsercet,js_code是前台登陆成功后返回给你的code,grant_type为固定值authorization_code.
appid跟secret的查看在微信公众平台:
注意:appid跟secret只有小程序的管理员可以看到,如果只是有权限的话,还是看不到,必须管理员扫码才可以看到,进去之后就在 设置→→→开发设置
controller中涉及到三个类,CommonUtil是用来请求微信接口的,TrustManager是管理器,WxConfig是配置一些你的小程序信息
