php curl的几种用法

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 bodycurl_setopt($ch, CURLOPT_NOBODY, 0);curl_setopt($ch, CURLOPT_HEADER, 0); // make sure we get the bodycurl_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
