瓶測試 - 功能測試錯誤 - 響應流[400不良請求]

Question

我試圖用瓶客戶端測試瓶應用程序。

我的應用途徑處理如下

@app.route('/', methods=['post', 'get']) 
@app.route('/index', methods=['post', 'get']) 
def index(): 

    login_form = LoginForm(request.form) 
    logout_form = LogoutForm(request.form) 
    short_url_form = ShortURLForm(request.form) 


    if request.method == 'POST' and short_url_form.validate(): 
     url = short_url_form.url.data 
     url_shortener_handler = urlShortener() 

     app.logger.debug('in post method to shorten Url(%s)', url) 

     # TODO have a mechanism for handling duplicate key error 
     short_url = url_shortener_handler.generateShortUrl() 

     if url_shortener_handler.saveUrl(short_url, url): 
      app.logger.debug('value of short url(%s) for url is (%s)', short_url, url) 
      return render_template('index.html', 
           login_form=login_form, 
           logout_form=logout_form, 
           shorturl_form=short_url_form, 
           shortURL=SITE_URL + '/' + short_url) 
     else: 
      app.logger.critical('Error in saving short url(%s) for url is (%s)', short_url, url) 
      flash('Internal error try again') 

    return render_template('index.html', 
         login_form=login_form, 
         logout_form=logout_form, 
         shorturl_form=short_url_form, 
         shortURL=None) 

而且short_url_form定義如下

class ShortURLForm(Form): 

    url = StringField('url', validators=[url(), data_required()]) 
    submit = SubmitField('Shorten') 

    def __init__(self, *args, **kwargs): 
     Form.__init__(self, *args, **kwargs) 

    def validate(self): 
     """ performs validation of input """ 
     if not Form.validate(self): 
      return False 
     return True 

，我與測試情況如下

class TestBasicUrlShortener(unittest.TestCase): 
    def setUp(self): 
     self.client = app.test_client() 
     self.baseURL = 'http://localhost:5000' 

    def create_app(self): 
     """ this is one of the functions that must be implemented for flask testing. """ 
     app = Flask(__name__) 
     app.config['TESTING'] = True 
     app.config['WTF_CSRF_ENABLED'] = False 
     WTF_CSRF_ENABLED = False 
     app.debug = True 
     self.baseURL = 'http://localhost:5000' 
     return app 

和測試當我使用客戶端發送郵件請求時，我收到400個錯誤的請求。

 def test_post_to_urlshortener(self): 
     """ When we send a post we expect it to return a output 
     containing the baseURL and short url """ 

     # monkeypatch the generate shortURL so that we know 
     # the correct value to expect and perform validation 
     # accordingly 
     from app.models import urlshortener 

      urlshortener.urlShortener.generateShortUrl = self.generate_shortURL 
     data = dict(url='http://www.google.com/', submit='Shorten') 

      rv = self.client.post('/', 
          data=data, 
          follow_redirects=False) 
      print rv 
      self.assertEqual(rv.status_code, 200) 
      shorturl = self.baseURL + '/' + self.generate_shortURL() 
      # print rv.data 
      assert shorturl in str(rv.data) 

      # cleanup so next time it works 
      urlshort = urlshortener.urlShortener() 
      urlshort.removeUrl(self.generate_shortURL()) 

代碼工作時，我用瀏覽器進行測試，即從測試失蹤，瀏覽器CSRF token.However我可以使用配置禁用CSRF保護的唯一參數（希望如此）

歡迎任何幫助縮小問題的指針。

的問題似乎是，即使在csrf_token被禁用，WTF-形式的問題https://github.com/lepture/flask-wtf/issues/208

的工作圍繞提到的是引發錯誤我所做的是爲了使代碼，解析輸出和提取物csrf_token。代碼如下

def getcsrf_value(self): 

    """ get csrf token """ 

    rv = self.client.get('/') 

    soup = BeautifulSoup(rv.data, 'html.parser') 
    tag = soup.body.find('input', attrs={'name' : 'csrf_token'}) 
    return tag['value']
