PHP - Validate the recaptcha v2 response

本文关键字：v2 响应 recaptcha 验证 PHP | 更新日期: 2023-09-27

#form.php
if(isset($_POST['g-recaptcha-response'])){
    $captcha=$_POST['g-recaptcha-response'];
    $captcha=$_GET["g-recaptcha-response"];
    $response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=__1234__&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
    echo $response;

的回报:

注意:未定义的索引:g-recaptcha-response在/var/www/clients/qmax/app/controllers/job_application_controller.php第114行{"success": false， "error-codes": ["missing-input-response"]}

echo $response->success;

的回报:

注意:试图获得非对象的属性/var/www/clients/qmax/app/controllers/job_application_controller.php在第119行

我只需要得到"成功"对象，然后我可以测试它是真还是假，我就完成了。

删除这一行:

$captcha = $_GET["g-recaptcha-response"];

然后你需要解码json谷歌像这样:

$g_response = json_decode($response);

然后检查if/else:

if ($g_response->success === true) echo "success!";
