OAuth2.0认证授权

认证授权过程

  • 服务提供方(provider),用户使用服务提供方来存储受保护的资源,如照片,视频,联系人列表
  • 用户,存放在服务提供方的受保护的资源的拥有者
  • 客户端,要访问服务提供方资源的第三方应用,通常是网站,如提供照片打印服务的网站。在认证过程之前,客户端要向服务提供者申请客户端标识使用OAuth进行认证和授权的过程如下所示:

用户想操作存放在服务提供方的资源。用户登录客户端向服务提供方请求一个临时令牌。服务提供方验证客户端的身份后,授予一个临时令牌。客户端获得临时令牌后,将用户引导至服务提供方的授权页面请求用户授权。在这个过程中将临时令牌和客户端的回调连接发送给服务提供方。用户在服务提供方的网页上输入用户名和密码,然后授权该客户端访问所请求的资源。授权成功后,服务提供方引导用户返回客户端的网页。客户端根据临时令牌从服务提供方那里获取访问令牌。服务提供方根据临时令牌和用户的授权情况授予客户端访问令牌。客户端使用获取的访问令牌访问存放在服务提供方上的受保护的资源。目录结构主目录basicauth

开发人员可以使用任何第三方包添加自定义cookie编码器/解码器。// 在这个例子中,我们将使用gorilla的securecookie:// 获取包 go get github.com/gorilla/securecookie// securecookie的示例可以在“sessions / securecookie”示例文件夹中找到。// 注意://

  • 去Github设置第三方授权登录,设置回调路径,把key,secret填入上面代码指定位置
  • 执行程序选择github 即可看到想要的效果
