PHP CURL采集百度搜寻结果图片不显示问题的解决方法

1.根据关键字采集百度搜寻结果

根据关键字采集百度搜寻结果,可以使用curl实现,代码如下:

<?php
function doCurl($url, $data=array(), $header=array(), $timeout=30){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
$response = curl_exec($ch);
if($error=curl_error($ch)){
die($error);
}
curl_close($ch);
return $response;
}
$wd = '仙剑奇侠传';
$url = 'http://www.baidu.com/s?wd='.urlencode($wd);
$data = array();
$header = array();
$response = doCurl($url, $data, $header, 5);
echo $response;
?>

输出后发现有部分图片不能显示

2.采集后的图片不显示原因分析

直接在百度中搜寻,页面是可以显示图片的。使用firebug查看图片路径,发现采集的图片域名与在百度搜寻的图片域名不同。

采集返回的图片域名 t11.baidu.com

正常搜寻的图片域名 ss1.baidu.com

查看采集与正常搜寻的html,发现有个域名转换的js是不一样的

采集

var list = {
"graph.baidu.com": "http://graph.baidu.com",
"t1.baidu.com":"http://t1.baidu.com",
"t2.baidu.com":"http://t2.baidu.com",
"t3.baidu.com":"http://t3.baidu.com",
"t10.baidu.com":"http://t10.baidu.com",
"t11.baidu.com":"http://t11.baidu.com",
"t12.baidu.com":"http://t12.baidu.com",
"i7.baidu.com":"http://i7.baidu.com",
"i8.baidu.com":"http://i8.baidu.com",
"i9.baidu.com":"http://i9.baidu.com",
};

正常搜寻

var list = {
"graph.baidu.com": "https://sp0.baidu.com/-aYHfD0a2gU2pMbgoY3K",
"t1.baidu.com":"https://ss0.baidu.com/6ON1bjeh1BF3odCf",
"t2.baidu.com":"https://ss1.baidu.com/6OZ1bjeh1BF3odCf",
"t3.baidu.com":"https://ss2.baidu.com/6OV1bjeh1BF3odCf",
"t10.baidu.com":"https://ss0.baidu.com/6ONWsjip0QIZ8tyhnq",
"t11.baidu.com":"https://ss1.baidu.com/6ONXsjip0QIZ8tyhnq",
"t12.baidu.com":"https://ss2.baidu.com/6ONYsjip0QIZ8tyhnq",
"i7.baidu.com":"https://ss0.baidu.com/73F1bjeh1BF3odCf",
"i8.baidu.com":"https://ss0.baidu.com/73x1bjeh1BF3odCf",
"i9.baidu.com":"https://ss0.baidu.com/73t1bjeh1BF3odCf",
};

因此可以断定是,百度根据来源地址、IP、header等参数,判断如果是采集的,则返回不同的js。

3.采集后图片不显示的解决方法

把采集到的html,根据定义的域名做一次批量转换即可。

<?php
function doCurl($url, $data=array(), $header=array(), $timeout=30){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
$response = curl_exec($ch);
if($error=curl_error($ch)){
die($error);
}
curl_close($ch);
return $response;
}
// 域名转换
function cdomain($str){
$baidu_domain = '{
"http://graph.baidu.com": "https://sp0.baidu.com/-aYHfD0a2gU2pMbgoY3K",

}';
$domain = json_decode($baidu_domain, true);
foreach($domain as $k=>$v){
$str = str_replace($k, $v, $str);
}
return $str;
}
$wd = '仙剑奇侠传';
$url = 'http://www.baidu.com/s?wd='.urlencode($wd);
$data = array();
$header = array();
$response = doCurl($url, $data, $header, 5);
echo cdomain($response); // 调用域名转换
?>

增加域名转换后,所有的图片都可以正常显示。
