在我的網絡應用程序中發送http請求，在werkzeug

中，我使用werkzeug來偵聽和處理請求。在其中一個功能中，我需要聽取請求（從A發出）併發送http請求到另一個服務器（B），然後在我得到B的響應後，我回應A的迴應。在我的網絡應用程序中發送http請求，在werkzeug

我對werkzeug不是很熟悉，也不確定它是否有發送請求的能力，所以我用httplib發送請求。

但我收到錯誤。

有很多運動部件的，我想知道以下幾點：1。確實WERKZEUG都有向外發送請求 2.什麼是錯誤

事業得到任何幫助的能力。

代碼：

def complete(self, request): 
    if request.method == 'GET': 
     location_id = self.extract_param_value(request,'location_id'); 
     status_code = self.extract_param_value(request,'status_code'); 

     req_url = something; 
     jsonData = { 'data' : {'status' : status_code, 'id': location_id}}; 
     jsonDataDump = json.dumps(jsonData); 
     #send request to B 
     connection = httplib.HTTPConnection(HOST, timeout=5); 
     body_content = jsonDataDump; 
     headers = {"Content-type": "application/json", "Accept": "text/plain"}; 
     connection.request('PUT', req_url, body_content, headers); #error occurs here 
     result = connection.getresponse(); 
     connection.close(); 
     #return response to A 
     response = Response(status=200); 

     return response;

錯誤：

WERKZEUG不是HTTP請求庫，使用httplib的（如你的例子）
檢查，捲曲，如果請求從主機成功排除網絡問題。您收到的錯誤是一般網絡錯誤。
