Question

我有一个云功能，可以发送自定义电子邮件验证电子邮件，该电子邮件包含一个重定向到我的网站的链接。我的问题是，当我在localhost上进行测试时，重定向URL转到生产站点。我知道这是预期的行为。

是否可以使用https可调用函数接收的context数据获取原始URL来生成更特定的重定向URL？

我无法对context对象进行字符串化处理，而没有收到TypeError: Converting circular structure to JSON错误，但是当我将其记录到控制台时，在firebase控制台中的cloud函数日志中，我在JSON的深处看到了原始URL。对象。

Is the origin value here guaranteed and reliable? Is there a better way to implement this?

Answer 1

您似乎可以发送context.rawRequest.headers.origin的值。无需发送整个对象。
