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;
}
$a = _curl("https://blog.wm404.com/",false,true,false,'https://blog.wm404.com/',true,true);
第二种:
适合请求获取txt这类文本等等
第三种:
比较全面的php curl封装类
<?php
function teacher_curl($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']) {
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $paras['ctime']);
} else {
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
} if (@$paras['rtime']) {
curl_setopt($ch, CURLOPT_TIMEOUT, $paras['rtime']);
} if (@$paras['post']) {
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $paras['post']);
} if (@$paras['header']) {
curl_setopt($ch, CURLOPT_HEADER, true);
} if (@$paras['cookie']) {
curl_setopt($ch, CURLOPT_COOKIE, $paras['cookie']);
} if (@$paras['refer']) { if ($paras['refer'] == 1) {
curl_setopt($ch, CURLOPT_REFERER, 'http://m.qzone.com/infocenter?g_f=');
} else {
curl_setopt($ch, CURLOPT_REFERER, $paras['refer']);
}
} if (@$paras['ua']) {
curl_setopt($ch, CURLOPT_USERAGENT, $paras['ua']);
} else {
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36");
} 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);
$body = substr($result, $headerSize);
$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;
}
get访问
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com");
post访问
echo teacher_curl("https://api.oioweb.cn/api/beian.php",[
'post'=>[
'url'=>'qq.com'
]
]);
携带Cookie访问
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com",[
'cookie'=>'cookie内容'
]);
模拟访问来源Refer
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com",[
'refer'=>'https://api.oioweb.cn'
]);
模拟UseaAgent
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.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://api.oioweb.cn/api/beian.php?url=qq.com",[
'post'=>[
'file'=>new CURLFile(realpath("Curl.jpg"))
]
]);
或
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com",[
'post'=>new CURLFile(realpath("Curl.jpg"))
]);
获取301跳转地址
echo teacher_curl("https://mmbizurl.cn/s/RNHSo6Dek",[
'loadurl'=>1
]);
查看返回Header信息
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com",[
'header'=>1
]);
设置请求头信息
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.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POST以后返回的Header、Body、Cookie内容
echo teacher_curl("https://api.oioweb.cn/api/beian.php?url=qq.com",[
'post'=>[
'user'=>123456,
'pwd'=>123
],
