Question

我正在将reCaptcha从谷歌添加到我的表单。问题是即使我按照谷歌的说明。我仍然可以按下提交按钮而不进行重新接收。任何想法请继续相关的代码片段。

<div class="g-recaptcha" data-sitekey="xxxxxxmyapikeyxxxxxxx_xxxxxxmyapikeyxxxxxxx"></div>  
                    <li class="buttons">
                <input type="hidden" name="form_id" value="1136056" />

                <input id="saveForm" class="button_text" type="submit" name="submit" value="Submit" />
        </li>
            </ul>

        </form>

此网页的表单部分中的此片段

[QUOTE]
When your users submit the form where you integrated reCAPTCHA, you'll     
get as part of the payload a string with the name "g-recaptcha-response". 
In order to check whether Google has verified that user, 
send a POST request with these parameters:

URL: https://www.google.com/recaptcha/api/siteverify
secret (required)   xxxxxmysecretkeyxxxxxxx
response (required) The value of 'g-recaptcha-response'.
remoteip    The end user's ip address.
[/QUOTE]

据我所知，我已将代码放在网页的指定区域。一个在HTML模板上的结束标记之前，以及我想要显示reCAPTCHA小部件的末尾的代码段。

我在提交按钮之前放了recaptcha。有一部分是关于服务器端集成的，我不明白。

因此我们设置表单并确保包含您的库，我阻止在recaptcha尚未完成时单击提交按钮并显示工具提示以通知用户需要继续。然后在使用回调方法完成后启用它。

<强>的login.php

<div class="formContainer">
    <script src='https://www.google.com/recaptcha/api.js'></script>
    <form action="loginHandler.php" method="post" name="login_form" id="loginForm" class="loginForm">  
        <h2>Login</h2>
        <p><input type="text" required placeholder="Email" name="email"></p>
        <p><input type="password" required placeholder="Password" name="password" id="password"></p>
        <div class="g-recaptcha" data-callback="captcha_filled"
                 data-expired-callback="captcha_expired" 
                 data-sitekey="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX">
        </div>
        <div>
            <p class="show-tt" data-toggle="tooltip" title="Complete the reCAPTCHA to login." data-placement="bottom">
                <input id="submitLogin" type="submit" value="Login">
            </p>
        </div>
    </form>
</div>

<script>
    //prevent submit and show tooltip until captch is complete.
    var submit = false;
    $("#submitLogin").prop('disabled', true);

    function captcha_filled() {
        submit = true;
        $("#submitLogin").prop('disabled', false);
        $(".show-tt").tooltip('destroy');
    }
    function captcha_expired() {
        submit = false;
        $("#submitLogin").prop('disabled', true);
        showTooltip();
    }
    function showTooltip () {
        $(".show-tt").tooltip('show');
    }
</script>

现在我们发布到loginHandler.php，或者您的表单提交的地方，然后我们将分配您的密钥，然后通过谷歌验证请求。

<强> loginHandler.php

$secret = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";

if (isset($_POST["g-recaptcha-response"])) {

    $url = 'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secret) .
            '&response=' . urlencode($_POST['g-recaptcha-response']) . '&remoteip=' . urlencode($_SERVER['REMOTE_ADDR']);
    //ip address is optional
    $result = json_decode(file_get_contents($url), true);

    if ($result != null && $result['success'] === true) {

        //success, handle login/submit data or whatever

    } else {
        //response is bad, handle the error
        header('Location: login.php?error=4');
    }
} else {
    //captcha response is not set, handle error
    header('Location: login.php?error=5');
}

即使已完成reCaptcha，提交按钮也会发送电子邮件
