PHP curl请求常用类库
在使用PHP工作中,经常会用到Curl的请求,下面是拿了一个比较适合的类库作为Curl工具使用
直接上源码,可以直接保存到自己的文件中
class HttpService
{
/**
* 错误信息
* @var string
*/
private static $curlError;
/**
* header头信息
* @var string
*/
private static $headerStr;
/**
* 请求状态
* @var int
*/
private static $status;
/**
* @return string
*/
public static function getCurlError()
{
return self::$curlError;
}
/**
* @return mixed
*/
public static function getStatus()
{
return self::$status;
}
/**
* 模拟GET发起请求
* @param $url
* @param array $data
* @param bool $header
* @param int $timeout
* @param string $cookie
* @return bool|string
*/
public static function getRequest($url, $data = array(), $header = false, $timeout = 10, $cookie = '')
{
if (!empty($data)) {
$url .= (stripos($url, '?') === false ? '?' : '&');
$url .= (is_array($data) ? http_build_query($data) : $data);
}
return self::request($url, 'get', array(), $header, $timeout, $cookie);
}
/**
* curl 请求
* @param $url
* @param string $method
* @param array $data
* @param bool $header
* @param int $timeout
* @param string $cookie
* @return bool|string
*/
public static function request($url, $method = 'get', $data = array(), $header = false, $timeout = 15, $cookie = '')
{
self::$status = null;
self::$curlError = null;
self::$headerStr = null;
$curl = curl_init($url);
$method = strtoupper($method);
//请求方式
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
//携带参数
if ($method == 'POST') {
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
} elseif ($method == 'GET' && count($data)) {
$url .= '?' . http_build_query($data);
curl_setopt($curl, CURLOPT_URL, $url);
}
//超时时间
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
//设置header头
if ($header !== false) curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_FAILONERROR, false);
//返回抓取数据
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
//输出header头信息
curl_setopt($curl, CURLOPT_HEADER, true);
//TRUE 时追踪句柄的请求字符串,从 PHP 5.1.3 开始可用。这个很关键,就是允许你查看请求header
curl_setopt($curl, CURLINFO_HEADER_OUT, true);
//https请求
if (1 == strpos("$" . $url, "https://")) {
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
}
//设置cookie
if ($cookie != '') curl_setopt($curl, CURLOPT_COOKIE, $cookie);
self::$curlError = curl_error($curl);
list($content, $status) = [curl_exec($curl), curl_getinfo($curl), curl_close($curl)];
self::$status = $status;
self::$headerStr = trim(substr($content, 0, $status['header_size']));
$content = trim(substr($content, $status['header_size']));
return (intval($status["http_code"]) === 200) ? $content : false;
}
/**
* 模拟POST发起请求
* @param $url
* @param array $data
* @param bool $header
* @param int $timeout
* @param string $cookie
* @return bool|string
*/
public static function postRequest($url, $data = array(), $header = false, $timeout = 10, $cookie = '')
{
return self::request($url, 'post', $data, $header, $timeout, $cookie);
}
/**
* 获取header头字符串类型
* @return mixed
*/
public static function getHeaderStr()
{
return self::$headerStr;
}
/**
* 获取header头数组类型
* @return array
*/
public static function getHeader()
{
$headArr = explode("\r\n", self::$headerStr);
return $headArr;
}
