#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'
