三方授权登陆（oauth）

基于Oauth2.0

oauth2.0四种授权模式

隐世授权模式

授权码授权模式（最完善）

密码模式

客户端凭证模式

1.vue请求跳转的微博的url发送给django端

2.django拼接url返回给vue端

3.vue通过url跳转到微博

4.微博完成授权返回code给vue

5.vue将code转发给django

6.django拿code去微博换取token

7.微博返回uid和token给django

8.django拿到uid判断微博用户是否存在本地

8.1存在直接登录  8.2不存在需要绑定本地用户

8.2.1有本地用户直接绑定  8.2.2没有注册后绑定

生成跳转到微博的url
