有没有办法告诉curl不使用缓存 [英] Is there a way to tell curl to not use cache

问题描述

我想要找出网址的档案大小：

  $ url1 ='www.google.com'; 
 $ curl1 = curl_init（）; 
 curl_setopt（$ curl1，CURLOPT_URL，$ url1）; 
 curl_setopt（$ curl1，CURLOPT_RETURNTRANSFER，TRUE）; 
 curl_exec（$ curl1）; 
 $ file_size = curl_getinfo（$ curl1，CURLINFO_SIZE_DOWNLOAD）; 
 $ file_size_kb = $ file_size / 1000; 
 echo $ file_size_kb; 
  

输出 43331 。我认为它太低，因为我有google缓存。这是真的吗？

解决方案

你可以使用

code> CURLOPT_FRESH_CONNECT 为此。从 curl_setopt

CURLOPT_FRESH_CONNECT TRUE可强制使用新的连接， >

  curl_setopt（$ curl1，CURLOPT_FRESH_CONNECT，TRUE）; 
  

I am trying to find out file size of an url:

$url1 = 'www.google.com';
$curl1 = curl_init();
curl_setopt($curl1, CURLOPT_URL, $url1); 
curl_setopt($curl1, CURLOPT_RETURNTRANSFER, TRUE);
curl_exec($curl1);
$file_size = curl_getinfo($curl1, CURLINFO_SIZE_DOWNLOAD ); 
$file_size_kb = $file_size / 1000;
echo $file_size_kb;

The output is 43331. I think its too low because i have google cached. Can this be true? Also i tested google on some other site that calculates size of url, and it was twice as big.

解决方案

You can use CURLOPT_FRESH_CONNECT for this. From curl_setopt

CURLOPT_FRESH_CONNECT TRUE to force the use of a new connection instead of a cached one.

curl_setopt($curl1, CURLOPT_FRESH_CONNECT, TRUE);
