前言

分享几种很好用的php进行url访问的curl封装方法，可以自定义请求头，十分友好，本人不长记这些工具类，因此放到博客以便自己实用，也可以分享给大家使用。

第一种：

适合请求第三方api获取json等等

function _curl($url,$post=0,$header=0,$cookie=0,$referer=0,$ua=0,$nobaody=0){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $httpheader[] = "Accept:*/*";
    $httpheader[] = "Accept-Encoding:gzip,deflate,sdch";
    $httpheader[] = "Accept-Language:zh-CN,zh;q=0.8";
    $httpheader[] = "Connection:close";
    curl_setopt($ch, CURLOPT_HTTPHEADER, $httpheader);
    if($post){
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    }
    if($header){
        curl_setopt($ch, CURLOPT_HEADER, TRUE);
    }
    if($cookie){
        curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    }
    if($referer){
        curl_setopt($ch, CURLOPT_REFERER, $referer);
    }
    if($ua){
        curl_setopt($ch, CURLOPT_USERAGENT,$ua);
    }else{
        curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.167 Safari/537.36');
    }
    if($nobaody){
        curl_setopt($ch, CURLOPT_NOBODY,1);
    }
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    $ret = curl_exec($ch);
    curl_close($ch);
    return $ret;
}
//使用示例：
$a = _curl("https://blog.wm404.com/",false,true,false,'https://blog.wm404.com/',true,true);

第二种：

适合请求获取txt这类文本等等

$f='https://xxxxxxx.com/abc.txt';
$opts = [
    "http" => [
        "method" => "GET",
        "header" => 
            "Accept-language: zh\r\n" .
            "referer: https://blog.wm404.com/\r\n"
    ]
];

$context = stream_context_create($opts);
$file = file_get_contents($f, false, $context);

$arr = explode("\r\n", $file);//转换成数组
//去除值中的空格
foreach ($arr as &$row) {
    $row = trim($row);
}
unset($row);

$n=count($arr); //获得总行数
$rnd=rand(0,$n);    //产生随机行号
$rnd_line=$arr[$rnd]; //获得随机行

第三种：

比较全面的php curl封装类

function teacher_curl($url, $paras = array()){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);    if (@$paras['Header']) {
        $Header = $paras['Header'];
    } else {
        $Header[] = "Accept:*/*";
        $Header[] = "Accept-Encoding:gzip,deflate,sdch";
        $Header[] = "Accept-Language:zh-CN,zh;q=0.8";
        $Header[] = "Connection:close";
    }
    curl_setopt($ch, CURLOPT_HTTPHEADER, $Header);    if (@$paras['ctime']) { // 连接超时
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $paras['ctime']);
    } else {
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
    }    if (@$paras['rtime']) { // 读取超时
        curl_setopt($ch, CURLOPT_TIMEOUT, $paras['rtime']);
    }    if (@$paras['post']) {
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $paras['post']);
    }    if (@$paras['header']) {

    }    if (@$paras['cookie']) {

    }    if (@$paras['refer']) {        if ($paras['refer'] == 1) {
            curl_setopt($ch, CURLOPT_REFERER, 'http://m.qzone.com/infocenter?g_f=');
        } else {

    }    if (@$paras['nobody']) {
        curl_setopt($ch, CURLOPT_NOBODY, 1);
    }
    curl_setopt($ch, CURLOPT_ENCODING, "gzip");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    if (@$paras['GetCookie']) {
        curl_setopt($ch, CURLOPT_HEADER, 1);
        $result = curl_exec($ch);
        preg_match_all("/Set-Cookie: (.*?);/m", $result, $matches);
        $headerSize = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
        $header = substr($result, 0, $headerSize); //状态码
        $body = substr($result, $headerSize); //响应内容
        $ret = [            "Cookie" => $matches, "body" => $body, "code" => $header
        ];
        curl_close($ch);        return $ret;
    }
    $ret = curl_exec($ch);    if (@$paras['loadurl']) {
        $Headers = curl_getinfo($ch);
        $ret = $Headers['redirect_url'];
    }
    curl_close($ch);    return $ret;
}
