PHP之模拟https协议POST请求

    $cookie ="123456789abcdefg";
    $url = "https://www.abc.com/";
    $data='{"username":"123","datetime":"2019-08-27"}';
    //return_code是http状态码
    list($return_code, $return_content) = http_post_data($url, $data, $cookie);
    if($return_code==200) print_r($return_content);
    exit;

    /**
     * @param $url
     * @param $data_string
     * @param $cookie
     * @return array
     * 模拟https协议POST请求
     */
    function http_post_data($url, $data_string, $cookie) {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);// 跳过证书检查，为true则从证书中检查SSL加密算法是否存在
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie:".$cookie, "Content-Type: application/json"));
        ob_start();
        curl_exec($ch);
        $return_content = ob_get_contents();
        ob_end_clean();
        $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        return array($return_code, $return_content);

注意点： 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  //跳过证书检查，为true则从证书中检查SSL加密算法是否存在
