我是Django的新手,现在在从当前视图重定向到另一个URL时遇到一些问题。在这种情况下,我想重定向到Spotify登录页面。
这是我的观点:
#############################################################################
client_id = 'somestring'; # Your client id
client_secret = 'anotherstring'; # Your secret
redirect_uri = 'http://127.0.0.1:8000/callback/'; # Your redirect uri
stateKey = 'spotify_auth_state'
#############################################################################
def generateRandomString(length):
text = ''
possible = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'
for i in range(0,length):
text += possible[math.floor(random.random() * len(possible))]
return text
##############################################################################
def login_process(request):
if request.method == 'GET':
state = generateRandomString(16)
print(str(state))
HttpResponse.set_cookie(stateKey, state)
#your application requests authorization
scope = 'user-top-read user-read-email'
return HttpResponseRedirect(request, 'https://accounts.spotify.com/authorize?' + urllib.parse.urlencode({
response_type: 'code',
client_id: client_id,
scope: scope,
redirect_uri: redirect_uri,
state: state
}), {})
def login_view(request, *args, **kwargs):
print(args, kwargs)
print(request.user)
#return HttpResponse("<h1>Hello world</h1>")
return render(request, "login.html", {})
def callback_view(request, *args, **kwargs):
return render(request, "callback.html", {})
这是我应该点击以重定向的链接:
<a href="login/">Login with spotify</a>
这是我的urls.py
urlpatterns = [
path('admin/', admin.site.urls),
path('', login_view, name='login_view'),
path('login/', login_process, name = 'login'),
path('callback/', callback_view, name = 'callback_view'),
]
我得到的错误是“ / login /'str'对象的AttributeError没有属性'cookies'”,我什至不知道方法“ return HttpResponseRedirect”是否是完成所有这些事情的正确方法。你能帮我吗?
答案 0 :(得分:1)
这里:
HttpResponse.set_cookie(stateKey, state)
您是在类本身而不是实例上调用HttpResponse.set_cookie
,因此您将获得一个将实例作为第一个参数的未绑定方法。正确的方法实际上是先实例化响应,然后在其上调用set_cookie
:
qs = urllib.parse.urlencode({
"response_type": 'code',
"client_id": client_id,
"scope": scope,
"redirect_uri": redirect_uri,
"state": state
})
url = 'https://accounts.spotify.com/authorize?{}'.format(qs)
response = HttpResponseRedirect(request, url)
reponse.set_cookie(whatever)
return response
