在我的网络应用程序中发送http请求，在werkzeug

中，我使用werkzeug来侦听和处理请求。在其中一个功能中，我需要听取请求（从A发出）并发送http请求到另一个服务器（B），然后在我得到B的响应后，我回应A的回应。在我的网络应用程序中发送http请求，在werkzeug

我对werkzeug不是很熟悉，也不确定它是否有发送请求的能力，所以我用httplib发送请求。

但我收到错误。

有很多运动部件的，我想知道以下几点：1。确实WERKZEUG都有向外发送请求 2.什么是错误

事业得到任何帮助的能力。

代码：

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;

错误：

WERKZEUG不是HTTP请求库，使用httplib的（如你的例子）
检查，卷曲，如果请求从主机成功排除网络问题。您收到的错误是一般网络错误。
