微信登录接口调用步骤
WX开放平台申请网站应用,获得APPID和SECRET,第三方应用接入WX登录
APPID:xxxxxxxxxxxxxx
SECRET:yyyyyyyyyyyyyyy
第一步:调用微信登录接口,用户扫码登录,生成code
https://open.weixin.qq.com/connect/qrconnect?appid=xxxxxxxxxxxxxx&redirect_uri=https%3A%2F%2Fp7yrpa.natappfree.cc&response_type=code&scope=snsapi_login&state=200
结果:
http://79n8s3.natappfree.cc/?code=0610Xey313BXSQ15G6v31H6wy310Xeyv&state=200
第二步:请求以下路径通过code获取access_token 参数:appid=APPID,secret=SECRET,code=填写上一步生成的code,grant_type=“authorization_code”,生成access_token
https://api.weixin.qq.com/sns/oauth2/access_token
https://api.weixin.qq.com/sns/oauth2/access_token?appid=xxxxxxxxxxxxxx&secret=yyyyyyyyyyyyyyy&code=061OWZMX1Rl7LZ0qICMX1I9CMX1OWZMK&grant_type=authorization_code
https://api.weixin.qq.com/sns/oauth2/access_token?appid=xxxxxxxxxxxxxx&secret=SECRETyyyyyyyyyyyyyyy&code=0610Xey313BXSQ15G6v31H6wy310Xeyv&grant_type=authorization_code
结果:
{
"access_token":"ACCESS_TOKEN", 接口调用凭证
"expires_in":7200, access_token接口调用凭证超时时间，单位（秒）
"refresh_token":"REFRESH_TOKEN", 用户刷新access_token
"openid":"OPENID", 授权用户唯一标识
"scope":"SCOPE", 用户授权的作用域，使用逗号（,）分隔
"unionid": "o6_bmasdasdsad6_2sgVt7hMZOPfL" 当且仅当该网站应用已获得该用户的userinfo授权时，才会出现该字段。
}
第三步:请求以下链接进行refresh_token 参数:appid=APPID,grant_type=‘refresh_token’,refresh_token=填写上一步获取到的refresh_token参数
https://api.weixin.qq.com/sns/oauth2/refresh_token?appid=APPID&grant_type=refresh_token&refresh_token=23_ivXL7QsljTjYUJaifpGajw6DaWu3N-2A5-GewcFpSEK_xZ_CSBGBJ35HpXS-qa4GwbsvrEHbibwJWma3OKpYr73m3ZnAi25_V3pezwRSO10
https://api.weixin.qq.com/sns/oauth2/refresh_token?appid=APPID&grant_type=refresh_token&refresh_token=REFRESH_TOKEN
结果:
{
"access_token":"ACCESS_TOKEN", 接口调用凭证
"expires_in":7200, access_token接口调用凭证超时时间，单位（秒）
"refresh_token":"REFRESH_TOKEN", 用户刷新access_token
"openid":"OPENID", 授权用户唯一标识
"scope":"SCOPE" 用户授权的作用域，使用逗号（,）分隔
}
第四步:请求以下连接查询用户基本信息 参数:access_token=填写上一步获取的access_token,openid=填写上一步获取的openid
https://api.weixin.qq.com/sns/userinfo
