URL引用向前self.assertRedirects斜槓（響應，expected_url，STATUS_CODE = 302，target_status_code = 200）

Question

，我有以下的TestCase

def testNoAccessWithoutLogin(self): 
    """ 
    Tests that redirected to the login page if you are not logged in 
    """ 
    response = self.client.get(reverse('expenseList'), follow=True) 
    expected_url = reverse('login') + "?next=" + reverse('expenseList') 
    self.assertRedirects(response, expected_url, status_code=302, 
     target_status_code=200) 
    expected_url = reverse('login') + "?next=" + reverse('purchaseList') 
    response = self.client.get(reverse('purchaseList'), follow=True) 
    self.assertRedirects(response, expected_url, status_code=302, 
     target_status_code=200) 
# end testNoAccessWithoutLogin 

而且我得到以失敗

==================================================================== FAIL: testNoAccessWithoutLogin (procurement.tests.expenseTests) ---------------------------------------------------------------------- Traceback (most recent call last): File "/Users/jason/public_html/activity/project/procurement/tests.py", line 66, in testNoAccessWithoutLogin target_status_code=200) File "/Users/jason/.virtualenvs/activity/lib/python2.7/site-packages/django/test/testcases.py", line 304, in assertRedirects (url, expected_url)) AssertionError: Response redirected to ' http://testserver/login/?next=%2Fprocurement%2FexpenseList%2F ', expected ' http://testserver/login/?next=/procurement/expenseList/ '

我認爲這是因爲「％2F」不等於「/」，但爲什麼url被引用？

被測試裝飾有

@login_required

的next查詢參數值的作用是URL編碼;所以你必須這樣做來驗證重定向。

response = self.client.get(reverse('expenseList'), follow=True) 
expected_url = reverse('login') + "?next=" + urllib.quote(reverse('expenseList'), "") 
self.assertRedirects(response, expected_url, status_code=302, 
    target_status_code=200) 

注意的第二個參數是urllib.quote""，如

urllib.quote(string[, safe]) 

Replace special characters in string using the %xx escape. Letters, digits, and the characters '_.-' are never quoted. By default, this function is intended for quoting the path section of the URL.The optional safe parameter specifies additional characters that should not be quoted — its default value is '/'.
