Question

php 获取 远程 内容

目标：http://www.lecai.com/lottery/draw/ajax_get_latest_draw_html.php?lottery_type=544
file_get_contents 用这个方法不行

$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$contents = curl_exec($ch);
curl_close($ch);
echo $contents;
用这个方法没有出现错误，但是没有输出任何内容

Answer 2

<?php
$url="http://www.lecai.com/lottery/draw/ajax_get_latest_draw_html.php?lottery_type=544";

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 5);
$code = curl_exec($ch);
$code=preg_replace("#\\\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'GBK', pack('H4', '\\1'))", $code);
$code=str_replace("\\","",$code);
curl_close($ch);
print_r($code);

?>

Answer 3

curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)');
加上这句,伪装成浏览器会增加成功率.
