PHPCurl实现登陆采集

注意事项：
1、网页编码问题，如果对方的网页编码与你的不一致，请自行使用iconv或mb_string进行编码转换。
2、COOKIE保存的路径必须是绝对路径，一开始测试的时候，在WINDOWS上怎么也保存不上COOKIE，请确认你的路径。

废话不多说，直接看代码：

'coldstar','password'=>'123456.');
$COOKIEpath = $_SERVER["DOCUMENT_ROOT"] .'\\' .MD5($UserURL);	//以登陆域名的MD5值设置为COOKIE文件名
$html = curl_post_contents($UserURL,$UserData,$COOKIEpath);	//模拟登陆
if($html){
	if(stripos($html,'登陆成功')){
		$html = curl_get_contents($testURL,True,$COOKIEpath);	//获取真正的内容
	}else{
		$html = '登陆失败';
	}
}
echo $html;


function curl_get_contents($url,$useCOOKIE = 0,$COOKIEpath = ''){
	$userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)';
	$referer = $url;
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);				//设置访问的url地址
	curl_setopt($ch, CURLOPT_TIMEOUT, 10);				//设置超时
	curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);	//用户访问代理 User-Agent
	curl_setopt($ch, CURLOPT_REFERER, $referer);		//设置 referer
	if($useCOOKIE){
		curl_setopt($ch, CURLOPT_COOKIEFILE, $COOKIEpath);	//COOKIE的存储路径,传送时使用
	}
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);		//跟踪301
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);		//返回结果
	$r = curl_exec($ch);
	curl_close($ch);
	return $r;
}

function curl_post_contents($url,$data = array(),$COOKIEpath = ''){
	$userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)';
	$referer = $url;
	if(!is_array($data) || !$url) return '';
	foreach($data as $key=>$value){$post .= urlencode($key).'='.$value.'&';}
	rtrim($post ,'&');
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);				//设置访问的url地址
	curl_setopt($ch, CURLOPT_TIMEOUT, 10);				//设置超时
	curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);	//用户访问代理 User-Agent
	curl_setopt($ch, CURLOPT_REFERER, $referer);		//设置 referer
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);		//跟踪301
	curl_setopt($ch, CURLOPT_POST, 1);					//指定post数据
	curl_setopt($ch, CURLOPT_POSTFIELDS, $post);		//添加变量
	curl_setopt($ch, CURLOPT_COOKIEJAR, $COOKIEpath);	//COOKIE的存储路径,返回时保存COOKIE的路径
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);		//返回结果
	$r = curl_exec($ch);
	curl_close($ch);
	return $r;
}
