获取用户信息，需要获取 [access\_token][access_token]、[openid][access_token]

然后调用接口[https://api.weixin.qq.com/cgi-bin/user/info?access\_token=ACCESS\_TOKEN&openid=OPENID&lang=zh\_CN][access_token]

[access\_token][access_token]:公众号的全局唯一票据,

获取[access\_token][access_token]，需要调用[https://api.weixin.qq.com/cgi-bin/token?grant\_type=client\_credential&appid=APPID&secret=APPSECRET][https_api.weixin.qq.com_cgi-bin_token_grant_type_client_credential_appid_APPID_secret_APPSECRET]

[openid：普通用户的标识，对当前公众号唯一][access_token]

获取openid需要先获取*code*，

获取code需要调用接口

https://open.weixin.qq.com/connect/oauth2/authorize?appid=appid&redirect\_uri=现在访问的方法的url&response\_type=code&scope=snsapi\_userinfo&state=STATE

获取code后，

再调用接口https://api.weixin.qq.com/sns/oauth2/access\_token?appid=appid&secret=secret&code=code&grant\_type=authorization\_code以获取openid
