基于OAuth2.0协议方式

什么是OAuth

OAuth： OAuth（开放授权）是一个开放标准，允许用户授权第三方网站访问他们存储在另外的服务提供者上的信息，而不需要将用户名和密码提供给第三方网站或分享他们数据的所有内容。

OAuth2.0

对于用户相关的OpenAPI（例如获取用户信息，动态同步，照片，日志，分享等），为了保护用户数据的安全和隐私，第三方网站访问用户数据前都需要显式的向用户征求授权。

QQ登录OAuth2.0采用OAuth2.0标准协议来进行用户身份验证和获取用户授权，相对于之前的OAuth1.0协议，其认证流程更简单和安全。

OAuth2.0总体处理流程

1 第一步：用户同意授权，获取code

2 第二步：通过code换取网页授权access_token

3 第三步：刷新access_token（如果需要）

4 第四步：拉取用户信息(需scope为 snsapi_userinfo)

实现微信授权获取信息

微信网页授权地址

https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login

1.填写网页授权回调地址权限

2.生成网页授权地址

3.跳转到回调地址获取授权码

4. 通过code换取网页授权access_token

https://api.weixin.qq.com/sns/oauth2/access_token?appid=wx5c43fde3c9733d9e&secret=b8b217126c33a5fb7074927d5e72a81a&code=061WfM4E0TABnc2Cv04E02Lb5E0WfM4b&grant_type=authorization_code

4. 拉取用户信息(需scope为 snsapi_userinfo)

准备工作：生成授权链接

https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect 若提示“该链接无法访问”，请检查参数是否填写错误，是否拥有scope参数对应的授权作用域权限。

https://open.weixin.qq.com/connect/oauth2/authorize?appid= wx5c43fde3c9733d9e &redirect_uri=http://127.0.0.1:8080/callback&response_type=code&scope= snsapi_userinfo &state=STATE#wechat_redirect

1 第一步：用户同意授权，获取code

2 第二步：通过code换取网页授权access_token

3 第三步：刷新access_token（如果需要）

4 第四步：拉取用户信息(需scope为 snsapi_userinfo)

5 附：检验授权凭证（access_token）是否有效
