目前正在自製一個IP池，但在驗證IP時使用了兩種方法，卻發現兩種方法得出的結果會不一樣！（方法1驗證成功，方法2卻失敗）

想請各位大大看一下是哪邊有問題<(_ _)>

方法1:

def parse(self, response):
...
  meta = {
    'port': port,
    'proxy': proxy,
    'dont_retry': True,
    'download_timeout': 5,
    '_proxy_scheme': scheme,
    '_proxy_ip': ip,
    'update': update
    }
  yield scrapy.Request('https://httpbin.org/ip',callback=self.proxy_check_available, meta=meta, dont_filter=True,errback = lambda x: self.download_errback(x,meta['proxy']))

def proxy_check_available(self, response):
  json_data = json.loads(response.text)['origin']
  proxy_ip = response.meta['_proxy_ip']+', '+response.meta['_proxy_ip']
  item = GetProxyItem()
  if proxy_ip == json.loads(response.text)['origin']:
    item['scheme'] = response.meta['_proxy_scheme']
    item['proxy'] = response.meta['proxy']
    item['port'] = response.meta['port']
    item['update'] = response.meta['update']
    yield item

方法2:

url = 'https://httpbin.org/ip'
headers = {
          "User_Agent" : "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/22.0.1207.1 Safari/537.1"
          # "Referer" : "http://www.xicidaili.com/nn/1"
        }
res = requests.get(url,proxies=proxies,headers=headers)
json_data = json.loads(res.text)['origin']
if proxy_ip == json_data:
  print('pass : '+ x['proxy'])
else:
  print('delete : ' + x['proxy'])
