PHP使用Curl函数进行远程请求案例，爬虫，可保存账户登录状态 CURL简介：CURL可以使用URL的语法模拟浏览器来传输数据，因为它是模拟浏览器，因此它同样支持多种协议，FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE 以及 LDAP等协议都可以很好的支持，包括一些：HTTPS认证，HTTP POST方法，HTTP PUT方法，FTP上传，keyberos认证，HTTP上传，代理服务器，cookies，用户名/密码认证，下载文件断点续传，上传文件断点续传，http代理服务器管道，甚至它还支持IPv6，scoket5代理服务器，通过http代理服务器上传文件到FTP服务器等等。本文主要介绍的是php远程请求CURL（爬虫、保存登录状态）的相关内容，下面话不多说了，来一起看看详细的介绍吧GET案例：<?php /** * curl_get * @param $url * @param null $param * @param null $options * @return array */ function curl_get($url, $param = null, $options = null) { if (empty($options)) { $options = array( 'timeout' => 30, // 请求超时 'header' => array(), // 数据格式如array('Accept: */*','Accept-Encoding: gzip, deflate, br') 'cookie' => '', // cookie字符串，浏览器直接复制即可 'cookie_file' => '', // 文件路径,并要有读写权限的 'ssl' => 0, // 是否检查https协议 'referer' => null ); } else { empty($options['timeout']) && $options['timeout'] = 30; empty($options['ssl']) && $options['ssl'] = 0; } $result = array( 'code' => 0, 'msg' => 'success', 'body' => '' ); if (is_array($param)) { $param = http_build_query($param); } $url = strstr($url, '?') ? trim($url, '&') . '&' . $param : $url . '?' . $param; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); // 设置url !empty($options['header']) && curl_setopt($ch, CURLOPT_HTTPHEADER, $options['header']); // 设置请求头 if (!empty($options['cookie_file']) && file_exists($options['cookie_file'])) { curl_setopt($ch, CURLOPT_COOKIEFILE, $options['cookie_file']); curl_setopt($ch, CURLOPT_COOKIEJAR, $options['cookie_file']); } else if (!empty($options['cookie'])) { curl_setopt($ch, CURLOPT_COOKIE, $options['cookie']); } curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); //curl解压gzip页面内容 curl_setopt($ch, CURLOPT_HEADER, 1); // 获取请求头 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 输出转移，不输出页面 !$options['ssl'] && curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $options['ssl']); // 禁止服务器端的验证ssl !empty($options['referer']) && curl_setopt($ch, CURLOPT_REFERER, $options['referer']); //伪装请求来源，绕过防盗 curl_setopt($ch, CURLOPT_TIMEOUT, $options['timeout']); //执行并获取内容 $output = curl_exec($ch); $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE); $header = substr($output, 0, $header_size); $output = substr($output, $header_size); //对获取到的内容进行操作 if ($output === FALSE) { $result['code'] = 1; // 错误 $result['msg'] = "CURL Error:" . curl_error($ch); } $result['header'] = $header; $result['body'] = $output; //释放curl句柄 curl_close($ch); return $result; } ?>POST案例：<?php /** * curl_post * @param $url 请求地址 * @param null $param post参数 * @param array $options 配置参数 * @return array */ function curl_post($url, $param = null, $options = array()) { if (empty($options)) { $options = array( 'timeout' => 30, 'header' => array(), 'cookie' => '', 'cookie_file' => '', 'ssl' => 0, 'referer' => null ); } else { empty($options['timeout']) && $options['timeout'] = 30; empty($options['ssl']) && $options['ssl'] = 0; } $result = array( 'code' => 0, 'msg' => 'success', 'body' => '' ); if (is_array($param)) { $param = http_build_query($param); } $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); // 设置url !empty($options['header']) && curl_setopt($ch, CURLOPT_HTTPHEADER, $options['header']); // 设置请求头 if (!empty($options['cookie_file']) && file_exists($options['cookie_file'])) { curl_setopt($ch, CURLOPT_COOKIEFILE, $options['cookie_file']); curl_setopt($ch, CURLOPT_COOKIEJAR, $options['cookie_file']); } else if (!empty($options['cookie'])) { curl_setopt($ch, CURLOPT_COOKIE, $options['cookie']); } curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); //curl解压gzip页面内容 curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $param); curl_setopt($ch, CURLOPT_HEADER, 1); // 获取请求头 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 输出转移，不输出页面 !$options['ssl'] && curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $options['ssl']); // 禁止服务器端的验证ssl !empty($options['referer']) && curl_setopt($ch, CURLOPT_REFERER, $options['referer']); //伪装请求来源，绕过防盗 curl_setopt($ch, CURLOPT_TIMEOUT, $options['timeout']); //执行并获取内容 $output = curl_exec($ch); $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE); $header = substr($output, 0, $header_size); $output = substr($output, $header_size); //对获取到的内容进行操作 if ($output === FALSE) { $result['code'] = 1; // 错误 $result['msg'] = "CURL Error:" . curl_error($ch); } $result['header'] = $header; $result['body'] = $output; //释放curl句柄 curl_close($ch); return $result; } ?>关于php远程请求CURL(爬虫，保存登录状态)的这篇文章到此结束。其他请求类型行请参考这篇文章：PHP进行各种网络请求的方式和实现函数总结

PHP进行各种网络请求的方式和实现函数总结首先，分析php发送网络请求的方法对于php发送网络请求，我们最常用的请求是curl。有时候我们也会使用file_get_contents函数来发送网络请求，但是file_get_contents只能完成一些间接的网络请求，稍微复杂一点的是无法完成的，比如文件上传、cookies、验证、表单提交等。php中的Curl可以使用url的语法来模拟浏览器传输数据。因为是模拟浏览器，所以也支持多种协议。FTP，FTPS，http，httpS，Gopher，Telnet，Dict，File，LDAP都可以很好的支持，包括一些:HTTPS认证，HTTP POST方法，Put方法，FTP上传，keyberos认证，HTTP上传，代理服务器，cookies，用户名/密码认证，下载文件断点续传，上传文件断点续传，HTTP代理服务器管道，甚至它支持IPv6，scoket5代理服务器，通过HTTP代理服务器上传文件到FTP服务器等。，所以我们在开发中尽量使用curl做网络请求，不管是简单的还是复杂的。二、file_get_contents发送网络请求示例file_get_contents(path,include_path,context,start,max_length);参数描述path必需。规定要读取的文件。include_path可选。如果也想在 include_path 中搜寻文件的话，可以将该参数设为 "1"。context可选。规定文件句柄的环境。context 是一套可以修改流的行为的选项。若使用 null，则忽略。start可选。规定在文件中开始读取的位置。该参数是 PHP 5.1 新加的。max_length可选。规定读取的字节数。该参数是 PHP 5.1 新加的。一般用file_get_contents或者fopen, file , readfile等函数读取url的时候会创建一个$http_response_header变量保存HTTP响应的报头,使用fopen等函数打开的数据流信息可以用stream_get_meta_data获取$html = file_get_contents('http://www.baidu.com'); print_r($http_response_header); $fp = fopen('http://www.baidu.com', 'r'); print_r(stream_get_meta_data($fp)); fclose($fp);摸拟post请求：$url = 'http://192.168.1.1/test.php'; $data = array( 'keyword' => 'test data', ); $content = http_build_query($data); $content_length = strlen($content); $options = array( 'http' => array( 'method' => 'POST', 'header' => "Content-type: application/x-www-form-urlencoded\r\n" . "Content-length: $content_length\r\n", 'content' => $content ) ); echo file_get_contents($url, false, stream_context_create($options));三、PHP通过curl方法发送网络请求curl可以支持https认证、http post、ftp上传、代理、cookies、简单口令认证等等功能,使用前需要先在你的PHP环境中安装和启用curl模块，这里有两种写法供大家参考：<?php function geturl($url){ $headerArray =array("Content-type:application/json;","Accept:application/json"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_HTTPHEADER,$headerArray); $output = curl_exec($ch); curl_close($ch); $output = json_decode($output,true); return $output; } function posturl($url,$data){ $data = json_encode($data); $headerArray =array("Content-type:application/json;charset='utf-8'","Accept:application/json"); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,FALSE); curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); curl_setopt($curl,CURLOPT_HTTPHEADER,$headerArray); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return json_decode($output，true); } function puturl($url,$data){ $data = json_encode($data); $ch = curl_init(); //初始化CURL句柄 curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); 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_CUSTOMREQUEST,"PUT"); //设置请求方式 curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//设置提交的字符串 $output = curl_exec($ch); curl_close($ch); return json_decode($output,true); } function delurl($url,$data){ $data = json_encode($data); $ch = curl_init(); curl_setopt ($ch,CURLOPT_URL,$put_url); curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "DELETE"); curl_setopt($ch, CURLOPT_POSTFIELDS,$data); $output = curl_exec($ch); curl_close($ch); $output = json_decode($output,true); } function patchurl($url,$data){ $data = json_encode($data); $ch = curl_init(); curl_setopt ($ch,CURLOPT_URL,$url); curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json')); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PATCH"); curl_setopt($ch, CURLOPT_POSTFIELDS,$data); //20170611修改接口，用/id的方式传递，直接写在url中了 $output = curl_exec($ch); curl_close($ch); $output = json_decode($output); return $output; } ?>一个函数片时各种请求：function sendCurl($url, $data = null,$method='POST') { $method=strtoupper($method); $start_wdmcurl_time = microtime(true); $header = array(' application/x-www-form-urlencoded'); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_FAILONERROR, false); // https 请求 if (strlen($url) > 5 && strtolower(substr($url, 0, 5)) == "https") { curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); } if($method=='GET'){ if($data && is_array($data) && count($data)>0 ){ $url.="?".http_build_query($data); } curl_setopt($ch, CURLOPT_URL, $url); }elseif($method=='POST'){ curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); if (is_array($data) && count($data)>0) { curl_setopt($ch, CURLOPT_POST, true); $isPostMultipart = false; foreach ($data as $k => $v) { if ('@' == substr($v, 0, 1)) { $isPostMultipart = true; break; } } unset($k, $v); if ($isPostMultipart) { curl_setopt($ch, CURLOPT_POSTFIELDS, $data); } else { curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data)); } } }elseif(in_array($method,['PUT','DELETE','PATCH'])){ curl_setopt($ch, CURLOPT_CUSTOMREQUEST,$method); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); } curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_HTTPHEADER,$header); $reponse = curl_exec($ch); curl_close($ch); return $reponse; }四、使用PHP Composer的扩展库guzzlehttpcomposer require guzzlehttp/guzzle$client = new \GuzzleHttp\Client(); $response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle'); echo $response->getStatusCode(); // 200 echo $response->getHeaderLine('content-type'); // 'application/json; charset=utf8' echo $response->getBody(); // '' // Send an asynchronous request. $request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org'); $promise = $client->sendAsync($request)->then(function ($response) { echo 'I completed! ' . $response->getBody(); }); $promise->wait();平常开发中尽量使用方法三，自定义curl处理网络请求，或者composer的guzzlehttp扩展库，用起来也很方便。
