Python 代理服務(wù)器

代理服務(wù)器用于通過另一臺服務(wù)器瀏覽到某些網(wǎng)站，以便瀏覽保持匿名。它也可以用來繞過特定IP地址的阻止。

我們通過傳遞代理服務(wù)器地址作為參數(shù)，使用urllib模塊中的urlopen方法訪問網(wǎng)站。

示例在下面的示例中，使用代理地址訪問網(wǎng)站twitter.com進(jìn)行匿名訪問。OK的響應(yīng)狀態(tài)證明已成功通過代理服務(wù)器訪問。

import urllib
 URL = 'http://www.xntutor.com'
 PROXY_ADDRESS = "202.54.11.6:8088"
 if __name__ == '__main__':
     resp = urllib.urlopen(URL, proxies = {"http" : PROXY_ADDRESS})
 print "Proxy server returns response headers: %s " %resp.headers
  
 

當(dāng)運(yùn)行上面的程序時，得到類似以下輸出：
