php远程请求CURL案例（爬虫、保存登录状态）

GET案例

/**
 * curl_get
 * @param $url
 * @param null $param
 * @param null $options
 * @return array
 */
function curl_get($url,$param = null,$options = null){
    if(empty($options)){
        $options = array(
            'timeout' 		=> 30,// 请求超时
            'header' 		=> array(),// 数据格式如array('Accept: */*','Accept-Encoding: gzip, deflate, br');直接复制浏览器请求头改成一维数组即可
            'cookie' 		=> '',// cookie字符串，浏览器直接复制即可
            'cookie_file'   => '',// 文件路径,并要有读写权限的
            'ssl' 			=> 0,// 是否检查https协议
            'referer' 		=> null
        );
    }else{
        empty($options['timeout']) && $options['timeout'] = 30;
        empty($options['ssl']) && $options['ssl']	= 0;
    }
    $result = array(
        'code'      => 0,
        'msg'       => 'success',

    }

}

POST案例

/**
 * curl_post
 * @param $url              请求地址
 * @param null $param       get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, 0);// 不获取请求头
    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);
    //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['body'] = $output;
    //释放curl句柄
    curl_close($ch);
    return $result;
}

其他请求类型请自己参考封装处理
