使用方法

GET访问

echo teacher_curl("https://kuaidi.jsonin.com/JT5124806639322.html");

POST访问

echo teacher_curl("https://kuaidi.ipip5.com",[
    'post'=>[
        'dh'=>'JT5124806639322'
    ]
]);

或

echo teacher_curl("https://kuaidi.jsonin.com/",[
    'post'=>'dh=JT5124806639322'
]);

携带Cookie访问

echo teacher_curl("https://www.xiaodoubi.com/",[
    'cookie'=>'cookie内容'
]);

模拟访问来源Refer

echo teacher_curl("https://www.xiaodoubi.com/",[
    'refer'=>'https://www.xiaof.com'
]);

模拟UseaAgent

echo teacher_curl("https://www.xiaodoubi.com/",[
    'ua'=>'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'
]);

文件上传

echo teacher_curl("https://www.ipip5.com/",[
    'post'=>[
        'file'=>new CURLFile(realpath("Curl.jpg"))
    ]
]);

或

echo teacher_curl("https://www.ipip5.com/",[
    'post'=>new CURLFile(realpath("Curl.jpg"))
]);

获取301跳转地址

echo teacher_curl("https://www.xiaof.com",[
    'loadurl'=>1
]);

设置请求头信息

echo teacher_curl("https://www.ipip5.com/",[
    'Header'=>[
        'accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3
accept-encoding: gzip, deflate, br
accept-language: zh-CN,zh;q=0.9
cache-control: max-age=0'
    ]
]);

获取请求的全部信息

echo teacher_curl("https://www.ipip5.com/today/api.php?type=json",[
    'post'=>[
        'user'=>123456,
        'pwd'=>123
    ],
    'GetCookie'=>1
]);

我自用的

function curl($url){ //Curl GET
    $ch = curl_init();     // Curl 初始化
    $timeout = 30;     // 超时时间：30s
    $ua='Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36';// 伪造抓取 UA
    $ip = mt_rand(11, 191) . "." . mt_rand(0, 240) . "." . mt_rand(1, 240) . "." . mt_rand(1, 240);
    curl_setopt($ch, CURLOPT_URL, $url);// 设置 Curl 目标
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);// Curl 请求有返回的值
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);// 设置抓取超时时间
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// 跟踪重定向
    curl_setopt($ch, CURLOPT_REFERER, 'https://www.baidu.com/');//模拟来路
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip));  //伪造IP
    curl_setopt($ch, CURLOPT_USERAGENT, $ua);// 伪造ua
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);// https请求 不验证证书和hosts
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);//强制协议为1.0
    curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );//强制使用IPV4协议解析域名
    $content = curl_exec($ch);
    curl_close($ch);// 结束 Curl
    return $content;// 函数返回内容
}
$url = 'https://www.xiaodoubi.com/';
echo curl($url);
