php利用curl爬虫爬取微信公众号，防止ip封锁

前段时间遇到一个需求，是定向抓取一批微信公众号，于是找到了搜狗搜索引擎比较好，下面贴出源代码，各位可以试下

public function test(){

//搜狗抓取微信公众号

$url="http://weixin.sogou.com/weixin?type=1&s_from=input&query=农产品&ie=utf8";

$ifpost = 0;

$datafields = '';

$cookiefile = '';

$v = false;

//构造随机ip

$ip_long = array(

array('607649792', '608174079'), //36.56.0.0-36.63.255.255

array('1038614528', '1039007743'), //61.232.0.0-61.237.255.255

);

$rand_key = mt_rand(0, 9);

$ip= long2ip(mt_rand($ip_long[$rand_key][0], $ip_long[$rand_key][1]));

//模拟http请求header头

curl_setopt($ch, CURLOPT_URL, $url);
