什么是url:
curl是利用URL语法在命令行方式下工作的文件传输工具。
php教程实例:
set_time_limit(0);
@date_default_timezone_set('Asia/Shanghai');
function curlrequest($url,$postfield,$proxy=""){
$proxy=trim($proxy);
$user_agent ="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)";
$ch = curl_init();????// 初始化CURL句柄
if(!empty($proxy)){
curl_setopt ($ch, CURLOPT_PROXY, $proxy);//设置代理服务器
}
curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL
//curl_setopt($ch, CURLOPT_FAILONERROR, 1); // 启用时显示HTTP状态码,默认行为是忽略编号小于等于400的HTTP信息
//curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);//启用时会将服务器服务器返回的“Location:”放在header中递归的返回给服务器
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);// 设为TRUE把curl_exec()结果转化为字串,而不是直接输出
curl_setopt($ch, CURLOPT_POST, 1);//启用POST提交
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfield); //设置POST提交的字符串
//curl_setopt($ch, CURLOPT_PORT, 80); //设置端口
curl_setopt($ch, CURLOPT_TIMEOUT, 25); // 超时时间
curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);//HTTP请求User-Agent:头
//curl_setopt($ch,CURLOPT_HEADER,1);//设为TRUE在输出中包含头信息
//$fp = fopen("example_homepage.txt", "w");//输出文件
//curl_setopt($ch, CURLOPT_FILE, $fp);//设置输出文件的位置,值是一个资源类型,默认为STDOUT (浏览器)。
curl_setopt($ch,CURLOPT_HTTPHEADER,array(
'Accept-Language: zh-cn',
'Connection: Keep-Alive',
'Cache-Control: no-cache'
));//设置HTTP头信息
$document = curl_exec($ch); //执行预定义的CURL
$info=curl_getinfo($ch); //得到返回信息的特性
//print_r($info);
if($info[http_code]=="405"){
echo "bad proxy {$proxy}\n";??//代理出错
exit;
}
//curl_close($ch);
return $document;
}
//请求URL
$url="http://example.cn/getInfo.php";
//POST提交数据,可用HTTPWATCH查看
$postfield="userName=test&year=2008&passWord=123456&Submit=%CC%E1%BD%BB";
//代理服务器
$proxy = '';
//请求
$str=curlrequest($url,$postfield,$proxy);
//输出结果
echo $str;
