google技术牛牛地，我无可奈何了。晕倒。。。。。。

这个页面地址可以在ie当中打开。
我想通过以下代码远程获取其页面源代码，但是不成功，不知道原因请高手指教。
<?php

我自己用curl和file_get_contents测试了一下，得到的结果很奇怪，file_get_contents响应是200 bad request, 而curl得到的响应头却是400，但内容不完整，body内容为空。。
以下是我测试代码和结果，希望对LZ有点用吧。虽然没能解决任何问题。curl的<?php$url = "http://googleads.g.doubleclick.net/pagead/sdo?client=dist-aff-pub-8581564299250417&output=html&dt=1246957659171&format=js_sdo&h=35&w=500&correlator=1246957659171&same_win=2&logo=left&rl_pos=right&cts_mode=rs&num_cts=2&box_h=26&box_w=215&u_h=768&u_w=1024&u_ah=738&u_aw=1024&u_cd=32&u_tz=480&u_his=0&u_java=true&u_nplug=0&u_nmime=0&frm=0&lmt=1246957658&url=http://127.0.0.1/search.html&dtd=0";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);$a = curl_exec($ch); //输出结果保存在$a中
$info = curl_getinfo($ch); //响应的headercurl_close($ch);
var_dump($a); //输出，可以看到结果里是 string(603) "<html><body style="background-color:transparent"></body></html> echo '<pre>';
print_r($info); //输出响应的header，可以看到[http_code] => 400
echo '</pre>';
?>
file_get_contents的<?php$url = "http://googleads.g.doubleclick.net/pagead/sdo?client=dist-aff-pub-8581564299250417&output=html&dt=1246957659171&format=js_sdo&h=35&w=500&correlator=1246957659171&same_win=2&logo=left&rl_pos=right&cts_mode=rs&num_cts=2&box_h=26&box_w=215&u_h=768&u_w=1024&u_ah=738&u_aw=1024&u_cd=32&u_tz=480&u_his=0&u_java=true&u_nplug=0&u_nmime=0&frm=0&lmt=1246957658&url=http://127.0.0.1/search.html&dtd=0";echo file_get_contents($url);//出错echo '<pre>';
print_r($http_response_header);//输出响应header，400 bad request
echo '</pre>';?>
以上2段代码的输出结果
curl的
string(603) "<html><body style="background-color:transparent"></body></html> "

我是7楼，弄错了，curl也是400 bad request,2个都一样，不过curl会输出一段代码。只不过body标签对里内容为空
<?php$url = "http://googleads.g.doubleclick.net/pagead/sdo?client=dist-aff-pub-8581564299250417&output=html&dt=1246957659171&format=js_sdo&h=35&w=500&correlator=1246957659171&same_win=2&logo=left&rl_pos=right&cts_mode=rs&num_cts=2&box_h=26&box_w=215&u_h=768&u_w=1024&u_ah=738&u_aw=1024&u_cd=32&u_tz=480&u_his=0&u_java=true&u_nplug=0&u_nmime=0&frm=0&lmt=1246957658&url=http://127.0.0.1/search.html&dtd=0";$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);$a = curl_exec($ch); //输出结果保存在$a中

print_r($info); //输出响应的header，可以看到[http_code] => 400
echo '</pre>';
?>
我完全能获取到,只是要伪装成浏览器就行.
这个是我这个结果:

12楼是对的，学习了，设置下httpheader,将自己伪装成浏览器就可以了。把代码整了下，是这样的<?php
$url = "http://googleads.g.doubleclick.net/pagead/sdo?client=dist-aff-pub-8581564299250417&output=html&dt=1246957659171&format=js_sdo&h=35&w=500&correlator=1246957659171&same_win=2&logo=left&rl_pos=right&cts_mode=rs&num_cts=2&box_h=26&box_w=215&u_h=768&u_w=1024&u_ah=738&u_aw=1024&u_cd=32&u_tz=480&u_his=0&u_java=true&u_nplug=0&u_nmime=0&frm=0&lmt=1246957658&url=http://127.0.0.1/search.html&dtd=0";$ch = curl_init();//使目标服务器认为请求方是浏览器
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.0.11) Gecko/2009060215 Firefox/3.0.11"
));curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);$a = curl_exec($ch); //输出结果保存在$a中curl_close($ch);echo $a; //输出结果
?>
