前端和后端的电子邮件验证解决方案

[英]Email validation solution for front and backend

原文 2014-12-01 12:48:15 4 1 java/ javascript/ regex/ validation/ email

We have to do email validation and there are a large number of solution. 我们必须进行电子邮件验证，并且有大量解决方案。 The email is not the primary email we are using across site so we are not planning on sending a email and verifying the account. 该电子邮件不是我们跨站点使用的主要电子邮件，因此我们不打算发送电子邮件并验证帐户。 Hence we we are relying on regex based validation solution. 因此，我们依赖于基于正则表达式的验证解决方案。

Now doing regex based validation in server-side(java) is generally discouraged and we are advised to use existing solution like EmailValidator or existing libraries. 现在，一般不建议在服务器端（java）中进行基于正则表达式的验证，建议您使用现有的解决方案，例如EmailValidator或现有的库。 Now the problem is to achieve consistency between front end validation(which would be regex based and implemented in javascript) and backend implementation (which will be in java). 现在的问题是要实现前端验证（将基于正则表达式并在javascript中实现）和后端实现（将在java中）之间的一致性。

Is there a solution to achieve consistency between these validation on front-end and backend automatically. 是否有解决方案可以自动实现前端和后端验证之间的一致性。

1 个解决方案

I see two solutions, that might not the most optimal but that are certainly worth a try. 我看到了两个解决方案，这些解决方案可能不是最理想的，但肯定值得一试。

1) You could implement a web-service that would return the result returned by EmailValidator and then call this webservice in your javascript to do the checks. 1）您可以实现一个Web服务，该服务将返回EmailValidator返回的结果，然后在您的JavaScript中调用此Web服务进行检查。

2) Try to find the regex used by EmailValidator (assuming they use a regex), and use the same in your javascipt. 2）尝试查找EmailValidator使用的正则表达式（假设他们使用的是正则表达式），并在您的javascipt中使用相同的正则表达式。
