I'm just trying to fetch the yahoo web page. www.yahoo.com
If I run my simple script from my hosted site, it works.
If I try it from my localhost. All I get is a header res开发者_如何转开发ponse with: "w32.fp.re1.yahoo.com uncompressed/chunked Wed Apr 27 15:13:48 PDT 2011"
Here is my code:
<?php
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Set a referer
curl_setopt($ch, CURLOPT_REFERER, "http://www.example.org/yay.htm");
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
print curl_download('http://www.yahoo.com/');
?>
Actually, the result starts with
HTTP/1.1 302 Found
which means there's a Location header in there. And there is:
Location: http://nl.yahoo.com/?p=us
This is just the response body:
<!-- w20.fp.ird.yahoo.com uncompressed/chunked Wed Apr 27 17:08:09 PDT 2011 -->
You need to tell cURL to follow Location headers. That's it.
The name of the option is CURLOPT_FOLLOWLOCATION. Set it to true:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
PS
After following 1 Location header, this is the start of the response body when I run your code + FOLLOWLOCATION:
<!DOCTYPE html>
<html lang="nl-NL" class="y-fp-bg y-fp-pg-grad bkt732">
