reCaptcha keys are tied to a certain domain + localhost (when you got your private/public keys from them). You can use it on another domain by requesting new private/public keys or by using a global key.
reCaptcha 密钥绑定到某个域 + 本地主机（当您从它们那里获得私钥/公钥时）。您可以通过请求新的私钥/公钥或使用全局密钥在另一个域上使用它。
From their website:
从他们的网站：
By default, your reCAPTCHA key is restricted to the specified domain, and any subdomains for additional security. A key for foo.com works on test.foo.com.
If you wish to use your key across a large number of domains (e.g., if you are a hosting provider, OEM, etc.), select the global key option. You may want to use a descriptive domain name such as "global-key.mycompany.com"
If you own multiple domain names (foocars.com and footrucks.com), you can sign up for multiple keys, or use a global key.
默认情况下，您的 reCAPTCHA 密钥仅限于指定的域和任何子域以提高安全性。foo.com 的密钥适用于 test.foo.com。
如果您希望在大量域中使用您的密钥（例如，如果您是托管服务提供商、OEM 等），请选择全局密钥选项。您可能希望使用描述性域名，例如“global-key.mycompany.com”
如果您拥有多个域名（foocars.com 和 footrucks.com），您可以注册多个密钥，或使用全局密钥。

It seems that Google has removed the Global Key for reCaptcha, as you can see here.
谷歌似乎已经删除了 reCaptcha 的全局密钥，你可以在这里看到。
In your localhost it works fine because your are using the keys provided to your domain. But when you upload the code you your production server, it seems that you are using the same keys to multiple domains (even though localhost might not be considered a domain). So you got that error. I fixed that creating new keys to another domain of mine and adding them to my localhost script. And to the production script, I kept the keys for that domain.
在您的本地主机中它工作正常，因为您使用的是提供给您的域的密钥。但是，当您将代码上传到您的生产服务器时，您似乎对多个域使用了相同的密钥（即使 localhost 可能不被视为域）。所以你得到了那个错误。我修复了为我的另一个域创建新密钥并将它们添加到我的本地主机脚本的问题。对于生产脚本，我保留了该域的密钥。
