我无法在我的网站上使用reCAPTCHA v3。我已经从Google reCAPTCHA v3网站中输入了正确的代码，但是它在右下角显示“网站所有者错误：无效的网站密钥”。
我只有7岁，如果我错过了一些事情，请放轻松
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Recaptcha test</title>
<script src="https://www.google.com/recaptcha/api.js"></script>
<script>
function onSubmit(token) {
document.getElementById("demo-form").submit();
}
</script>
<script src="https://www.google.com/recaptcha/api.js?render=reCAPTCHA_site_key"></script>
<body>
<button class="g-recaptcha"
data-sitekey="reCAPTCHA_site_key"
data-callback='onSubmit'
data-action='submit'>Submit</button>
<script>
function onClick(e) {
e.preventDefault();
grecaptcha.ready(function() {
grecaptcha.execute('reCAPTCHA_site_key', {action: 'submit'}).then(function(token) {
// Add your logic to submit to your backend server here.
});
});
}
</script>
</head>
</body>
</html>
然后，我尝试了reCAPTCHA v2复选框，发生了同样的事情。虽然，“网站所有者错误：无效的网站密钥”现在位于左上方：
<!DOCTYPE html>?
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Recaptcha test</title>
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit"
async defer>
</script>
<body>
<form action="?" method="POST">
<div class="g-recaptcha" data-sitekey="your_site_key"></div>
<br/>
<input type="submit" value="Submit">
</form>
<script type="text/javascript">
var onloadCallback = function() {
alert("grecaptcha is ready!");
};
</script>
</head>
</body>
</html>
我已经尝试过您提到的reCAPTCHA v3代码。
reCAPTCHA_site_key位于三个位置，请检查是否在标题"COPY SITE KEY"下用正确的站点密钥替换了它。
原因是显示“网站所有者错误：无效的网站密钥”，原因是您可能正在尝试文件系统访问该密钥。它在文件系统上不起作用，即，这将不起作用：file:///E:/Personal%20Data/stackoverflow/recapcha.html
将您的站点托管在IIS / Node等本地服务器上，并在Recaptcha的域配置中添加相同的域。
for example if your website is: https://www.testingrecapcha.com/ then add testingrecapcha.com in domains of rechapcha configurations. (to reach admin console of recapcha, use this: https://www.google.com/recaptcha/admin and select your relevant site and click on settings icon).
