Python封装 HTTP POST和Get请求方法

get请求方法

    def get(self, url, params):
        params = urllib.parse.urlencode(eval(params))  # 将参数转为url编码字符串
        url = 'http://' + self.host + ':' + str(self.port)  + url + params
        request = urllib.request.Request(url, headers=self.headers)

        try:
            response = urllib.request.urlopen(request)
            response = response.read().decode('utf-8')  ## decode函数对获取的字节数据进行解码
            json_response = json.loads(response)  # 将返回数据转为json格式的数据
            return json_response
        except Exception as e:
            print('%s' % e)
            return {}

post请求方法

    def post(self, url, data):
        data = json.dumps(eval(data))
        data = data.encode('utf-8')
        url = 'http://' + self.host + ':' + str(self.port)  + url
        try:
            request = urllib.request.Request(url, headers=self.headers)
            response = urllib.request.urlopen(request, data)
            response = response.read().decode('utf-8')
            json_response = json.loads(response)
            return json_response
        except Exception as e:
            print('%s' % e)
            return {}
