注意。此URL的域名,必须全然匹配企业应用设置项中的‘可信域名‘。否则获取用户信息时会返回50001错误码。
可信域名设置不包括"http://",仅仅需域名或IP就可以。
OAuth2验证能够使用多种方式,此处使用注解方式。设计思路是在须要获取用户信息的GET请求上加入注解。然后在调用的时候推断是否包括此注解,然后做处理流程。
每次请求包括2种情况:
1.不须要获取用户信息,直接跳转到指定视图;
2.须要获取用户信息,此处分2种情况:
a.session中存储了之前获取的用户信息,则直接跳转到指定视图。
b.session中不包括用户信息。则须要构造带回调參数的URL去微信APIserver获取code參数,然后通过code參数调用API换取Userid并保存到session。然后再次跳转到初始请求的视图页面。
详细处理流程例如以下图:

创建拦截器:OAuth2Interceptor
