[置顶] django实现qq一键登录（qq互联）

#在login登录url下留出qq登录url
#eg:www.323.com/login?type=qq

tp = request.GET.get('type',None)
if tp:
code_url = 'https://graph.qq.com/oauth2.0/authorize'
parm = {
'response_type':'code',
'client_id':'你的appid',
'redirect_uri':'www.323.com/qq',
'state':'test'
}
auth_url = '%s?%s'%(code_url, urlencode(parm))
return HttpResponseRedirect(auth_url)
else:
return render(request, 'login.html', locals())

#其中redirect_uri为回调url，qq服务器收到登录请求后调用你的后台实现
#www.323.com/qq  指向如下实现

#流程如下：
#1.www.323.com/login?type=qq
#2.--->跳转qq登录页面
#3.--->qq调用后台www.323.com/qq
#4.--->映射处理登录验证
#qq = QQ(^$#%%$)
#access_token = qq.get_access_token()
#openid = qq.get_openid(access_token)
#user_info = qq.get_userinfo(access_token,openid) #返回字典
#5.保持用户信息到本地数据库
#成功登录后跳转到登录前页面

#QQ登录
#token_url = 'https://graph.qq.com/oauth2.0/token'
#auth_url = 'https://graph.qq.com/oauth2.0/me'
