2019/6/30 15:24:00
本文主要是介绍php下通过curl抓取yahoo boss 搜索结果的实现代码,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
1.编写curl类,进行网页内容抓取
class CurlUtil
{
private $curl;
private $timeout = 10;
/**
* 初始化curl对象
*/
public function __construct()
{
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
curl_setopt($this->curl, CURLOPT_HEADER, false); //设定是否显示头信息
curl_setopt($this->curl, CURLOPT_NOBODY, false); //设定是否输出页面内容
curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT, $this->timeout);
curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($this->curl, CURLOPT_AUTOREFERER, true);
}
/**
* 注销函数 关闭curl对象
*/
public function __destruct()
{
curl_close($this->curl);
}
/**
* 获取网页的内容
*/
public function getWebPageContent($url)
{
curl_setopt($this->curl, CURLOPT_URL, $url);
return curl_exec($this->curl);
}
}
2.创建curl对象
$CurlUtil = new CurlUtil();
3.抓取yahoo搜索结果
function getYahooSearch(CurlUtil $curl, $key)
{
$key = urlencode($key);
$searchUrl = "http://boss.yahooapis.com/ysearch/web/v1/$key?appid=你的雅虎appid&lang=tzh®ion=hk&abstract=long&count=20&format=json&start=0&count=10";
$josnStr = $curl->getWebPageContent($searchUrl);
$searchDataInfo = json_decode($josnStr, true);
$searchData = $searchDataInfo['ysearchresponse']['resultset_web'];
$returnArray = array();
if (!empty($searchData)) {
foreach ($searchData as $data) {
$returnArray[] = array("url" => $data['url'], "date" => $data['date'], 'title' => strip_tags($data['title']), 'description' => strip_tags($data['abstract']));
}
}
return $returnArray;
}
4.测试结果
var_dump(getYahooSearch($CurlUtil, "百度"));
复制代码 代码如下:
class CurlUtil
{
private $curl;
private $timeout = 10;
/**
* 初始化curl对象
*/
public function __construct()
{
$this->curl = curl_init();
curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($this->curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)");
curl_setopt($this->curl, CURLOPT_HEADER, false); //设定是否显示头信息
curl_setopt($this->curl, CURLOPT_NOBODY, false); //设定是否输出页面内容
curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT, $this->timeout);
curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($this->curl, CURLOPT_AUTOREFERER, true);
}
/**
* 注销函数 关闭curl对象
*/
public function __destruct()
{
curl_close($this->curl);
}
/**
* 获取网页的内容
*/
public function getWebPageContent($url)
{
curl_setopt($this->curl, CURLOPT_URL, $url);
return curl_exec($this->curl);
}
}
2.创建curl对象
复制代码 代码如下:
$CurlUtil = new CurlUtil();
3.抓取yahoo搜索结果
复制代码 代码如下:
function getYahooSearch(CurlUtil $curl, $key)
{
$key = urlencode($key);
$searchUrl = "http://boss.yahooapis.com/ysearch/web/v1/$key?appid=你的雅虎appid&lang=tzh®ion=hk&abstract=long&count=20&format=json&start=0&count=10";
$josnStr = $curl->getWebPageContent($searchUrl);
$searchDataInfo = json_decode($josnStr, true);
$searchData = $searchDataInfo['ysearchresponse']['resultset_web'];
$returnArray = array();
if (!empty($searchData)) {
foreach ($searchData as $data) {
$returnArray[] = array("url" => $data['url'], "date" => $data['date'], 'title' => strip_tags($data['title']), 'description' => strip_tags($data['abstract']));
}
}
return $returnArray;
}
4.测试结果
var_dump(getYahooSearch($CurlUtil, "百度"));
