前提需要php 安装 curl 扩展

curl GET 方法

    $ch = curl_init();//初始化curl
    curl_setopt($ch, CURLOPT_URL, $url);//设置url属性
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1)；
    curl_setopt($ch, CURLOPT_HEADER, 0);
    $output = curl_exec($ch);//获取数据
    curl_close($ch);//关闭curl
    return $output;

curl POST 方法

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;

如果你post和get同时使用 那就封装成一个函数来使用吧~

public function curlGet($url,$method,$post_data = 0){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    if ($method == 'post') {
        curl_setopt($ch, CURLOPT_POST, 1);

        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    }elseif($method == 'get'){
        curl_setopt($ch, CURLOPT_HEADER, 0);
    }
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
