Question

php curl get内容多大

Answer 1

总结一下项目中用到curl的几种方式
1. php curl的默认调用方法，get方式访问url
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); //设置http头
curl_setopt($ch, CURLOPT_ENCODING, "gzip" ); //设置为客户端支持gzip压缩
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30 ); //设置连接等待时间
curl_setopt($ch, CURLOPT_URL, $url );
curl_exec( $ch );
if ($error = curl_error($ch) ) {//出错处理return -1;}fclose($fp);
$curl_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //获取http返回值
if( $curl_code == 200 ) {
//正常访问url}//异常
2. 设置http header支持curl访问lighttpd服务器Java代码$header[]= 'Expect:';
$header[]= 'Expect:';
3. 设置curl，只获取http header，不获取body：Java代码curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
或者只获取body：Java代码curl_setopt($ch, CURLOPT_HEADER, 0); // make sure we get the body
curl_setopt($ch, CURLOPT_NOBODY, 0);
curl_setopt($ch, CURLOPT_HEADER, 0); // make sure we get the body
curl_setopt($ch, CURLOPT_NOBODY, 0);
4. 访问虚拟主机，需设置Host
$header[]= 'Host: '.$host;
5. 使用post, put, delete等REStful方式访问urlpost:curl_setopt($ch, CURLOPT_POST, 1 );
put, delete:
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE"); //或者PUT，需要服务器支持这些方法。6. 保存下载内容为文件
