oAuth2.0 第三方登录（Github+QQ+新浪微博）django开发

痛定思痛。 2022-06-01 09:09 364阅读 0赞

# oAuth2.0开发流程 #

OAuth（开放授权 Open Authorization）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。  
**处理流程包括：**

*  获取授权Code
 *  利用Code请求Access Token (令牌)
 *  利用令牌请求用户的Openid及其他用户用户信息 **（每个用户拥有唯一的Openid，因此可以通过Openid标识用户）**  
    ![这里写图片描述][format_png]  
    **回调地址**就是你接受code的url，要在第三方登录平台上填写，这样才能把code传递给你的网站，我这里填写的是http://127.0.0.1:8000/ 用于测试。

# 获取应用Id和秘钥 #

开发之前，需要前往第三方登录的开发者平台[QQ][]、[新浪微博][Link 1]、[Github][]，注册账号并填写信息申请接入，成功后会给你一个ID和秘钥，以后你就通过该ID和秘钥来获取令牌，从而实现第三方登录。申请ID和秘钥时Github不需要审核，很简单，而QQ和新浪微博需要审核，稍微麻烦一点。

# settings设置 #

#Oauth
    
    #github
    GITHUB_APP_ID = '************'
    
    GITHUB_KEY = '************'
    
    GITHUB_CALLBACK_URL = 'http://127.0.0.1:8000/oauth/github_check'  #填写你的回调地址
    
    #QQ
    QQ_APP_ID = '************'
    
    QQ_KEY = '*******************8'
    
    QQ_CALLBACK_URL = 'http://127.0.0.1:8000/oauth/qq_check'    #填写你的回调地址
    
    #新浪微博
    WEIBO_APP_ID = '************'
    
    WEIBO_KEY = '*****************'
    
    WEIBO_CALLBACK_URL = 'http://127.0.0.1:8000/oauth/weibo_check'    #填写你的回调地址

# 模型 #

from django.db import models
    from users.models import User
     
    #用户登录的类型
    type=(
    	('1','github'),
    	('2','qq'),
    	('3','weibo')
    )
    
    class OAuth_ex(models.Model):
    	user = models.ForeignKey(User)           #User为本网站的用户模型，每个第三方账号都要绑定本站账号
    	openid = models.CharField(max_length=100,default='')
    	type = models.CharField(max_length=1,choices=type)

# url配置 #

from django.conf.urls import url
    from . import views
    
    app_name='oauth'
    
    urlpatterns=[
    	url(r'github_login',views.git_login,name='github_login'),
    	url(r'github_check',views.git_check,name='github_check'),
    	url(r'qq_login',views.qq_login,name='qq_login'),
    	url(r'qq_check',views.qq_check,name='qq_check'),
    	url(r'weibo_login',views.weibo_login,name='weibo_login'),
    	url(r'weibo_check',views.weibo_check,name='weibo_check'),
    	url(r'bind_email',views.bind_email,name='bind_email'),   #通过邮箱将第三方账户绑定到本站账号
    ]

# 辅助类 #

因为三种登录方式都遵循相似的处理流程，因此我们新建一个文件，将登录所需要的方法都封装到对应的类中，减少代码冗余，也方便理解。
