　　例子, 模拟登陆

代码如下

/**
* 模拟登陆
* $url 请求地址
* $post 需要POST的数据
* $cookie 登陆时取的的COOKIE
* $cookiejar cookie要存到的位置例如/tmp/test.cookie
* $referer 上页地址
*
**/
function vcurl($url, $post = '', $cookie = '', $cookiejar = '', $referer = ''){
$tmpInfo = '';
//用来存放cookie的文件
//初始化curl
$curl = curl_init();
//设定目标网址
curl_setopt($curl, CURLOPT_URL, $url);
//使用目前所用的浏览器代理
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
//curl_setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
//如果有Ref参数，则设置Referer头，否则自动设置Referer头
if($referer) {
curl_setopt($curl, CURLOPT_REFERER, $referer);
} else {
curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
}
//如果有post数据参数，则方法为POST，并且设置数据，否则为GET
if($post) {
//发送一个常规的POST请求，默认类型为：application/x-www-form-urlencoded，www.111cn.net表单提交
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
}
//如果有cookie参数，则设置
if($cookie) {
curl_setopt($curl, CURLOPT_COOKIE, $cookie);
}
//如果有cookie文件参数，则设置存取Cookie文件名
if($cookiejar) {
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookiejar);
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookiejar);
}
//如果是302转移，则返回转移后的网址及内容
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
//设置执行的最大秒数
curl_setopt($curl, CURLOPT_TIMEOUT, 100);
//返回内容中是否包含头信息
curl_setopt($curl, CURLOPT_HEADER, 0);
//把返回的结果存在文件或者变量中，而不是直接显示在浏览器
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//执行函数后的返回结果
$tmpInfo = curl_exec($curl);
//如果出错，显示错误信息
if (curl_errno($curl)) {
$tmpInfo = '

<b>错误:</b><br>'.curl_error($curl);<br>
            }<br>
            //关闭curl对象<br>
            curl_close($curl);<br>
            //返回结果<br>
            return  $tmpInfo;<br>
            }

Copy after login

　　例子、soap

代码如下

function vcurlsoap($url, $SoapRequest, $SoapAction) {
$ch = curl_init (); //initiate the curl session
curl_setopt ( $ch, CURLOPT_URL, $url ); //set to url to post to
curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 ); // return data in a variable
curl_setopt ( $ch, CURLOPT_HEADER, 0 );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt ( $ch, CURLOPT_POSTFIELDS, $SoapRequest ); // post the xml
curl_setopt ( $ch, CURLOPT_TIMEOUT, 60 ); // set timeout in seconds
curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, 0 );
$header = array ("Content-Type: text/xml" );
$header [] = "Content-Length: ".strlen($SoapRequest);
if (! is_null ( $SoapAction ))
$header [] = 'SOAPAction: "' . $SoapAction . '"';
curl_setopt ( $ch, CURLOPT_HTTPHEADER, $header );
$xmlResponse = curl_exec ( $ch );
curl_close ( $ch );
return $xmlResponse;
}
