python - Django 不在重定向到其他 View 之间保存 session

Question

我正在使用 django session 数据来验证 oauth_2 身份验证是否成功。但是，django 不会在 View 之间保存 session 数据。

@never_cache
def login(request):

    microsoft = OAuth2Session(client_id,scope=scope,redirect_uri=redirect_uri)
    global state
    authorization_url, state = microsoft.authorization_url(authorization_base_url)
    # State is used to prevent CSRF, keep this for later.
    request.session['oauth_state'] = state

    return HttpResponseRedirect(authorization_url)  
@never_cache
def authorization(request):
    print(request.session.get('oauth_state')) ##This is where I'm having a problem. 'oauth_state' prints none!

    microsoft = OAuth2Session(client_id,scope=scope,redirect_uri=redirect_uri)
    token = ""
    try:
         users = 'https://graph.microsoft.com/v1.0/me' ##msgraph query url- 
                                                          ##This query is purelyjust used to 
                                                          ##authenticate user!
         token = microsoft.fetch_token(token_url, client_secret=client_secret,code=request.GET.get('code', ''))
         header = {'Authorization': 'Bearer ' + token['access_token']}
         response = requests.get(url = users, headers = header)
         print(response.text)
         print(response.status_code)
         if int(response.status_code) != 200: ##if status code is not 200, then authentication failed. Redirect to login.
             print ('Not validated. Return to login.')
             return redirect('http://localhost:8000/login')
         check_for_authorized = True
         print(token)
    except Exception as e:
       print ('User not does not have authentication rights')
       return redirect('http://localhost:8000/login')

    return HttpResponseRedirect('http://localhost:8000/search')

在第一行授权下看我打印状态旁边的注释。你为什么认为这是？ session 数据不应该在 View 之间共享。

保存 session 后使用它 request.session.modified = True

request.session['oauth_state'] = state
request.session.modified = True
