我想在后端使用 Django 和 Django-REST 框架来对本机 android 应用程序上的用户进行身份验证。我目前正在使用基于令牌的身份验证系统。（更多细节）

我已经实施了指南中列出的完全相同的过程来设置令牌身份验证。

现在我希望我的用户能够获取令牌以换取凭据。我使用以下代码发出 POST 请求：

      JSONObject cred = new JSONObject();

            try {
                cred.put("password",mPassword);
                cred.put("username",mEmail);
            } catch (JSONException e) {
                e.printStackTrace();
            }

            try {
               
                HttpClient httpClient = new DefaultHttpClient();

                HttpPost httpPost = new HttpPost(Common.getServerUrl()+"/api-token-auth/");
                StringEntity credentials = new StringEntity( cred.toString());
                credentials.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                httpPost.setHeader("Accept", "application/json");
                httpPost.setHeader("Content-type", "application/json");
                httpPost.setEntity(credentials);
                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();

                // Read content & Log
                inputStream = httpEntity.getContent();
                Log.i("Asynctask", cred .toString());
...

但是，当我将其发布到“views.obtain_auth_token”的 django 后端时，我总是出现此错误：

在服务器上：

"POST …

为 Django 编写的两个 JWT 包都给我带来了文档不佳的问题，所以我尝试了 DRF-auth_token 包。这是我遵循的一个很好的例子，Django Rest Framework Token Authentication。理论上你应该能够去

localhost:8000/api-token-auth/

网址.py：

from django.conf.urls import url, include
from django.contrib import admin
from django.contrib.auth.models import User
from rest_framework.authtoken import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^api/', include('api.urls', namespace='api')),
    url(r'^orders/', include('orders.urls', namespace='orders')),
    url(r'^api-token-auth/', views.obtain_auth_token, name='auth-token'),

]

为用户获取令牌不起作用，所以我自己重写了它以使其工作：

@api_view(['POST'])
def customer_login(request):
    """
    Try to login a customer (food orderer)
    """
    data = request.data

    try:
        username = data['username']
        password = data['password']
    except:
        return Response(status=status.HTTP_400_BAD_REQUEST)

    try:
        user = User.objects.get(username=username, password=password)
    except:
        return …
