已发送邮件中的动态链接 [英] dynamic link inside Sent mail

问题描述

我有一个邀请页面，该页面的成员可以向任何人发送简历
受邀者会收到带有某些链接的电子邮件
一个链接用于接受此邀请
另一个名为(取消订阅)的链接
我想在使用点击时更改此链接文本

问题是我无法做到这一点，因为已发送的邮件是作为文件后面的代码内部的字符串完全创建的，因此我真的需要帮助，示例代码

非常感谢

推荐答案

我将这样进行:
-由于每条邀请都是在服务器上生成的，因此我会为其生成一个长而唯一的随机ID
-我会将ID与被邀请者数据一起存储在数据库中，并存储一个"subscribed"标志
-我会将这个ID作为参数添加到链接中，例如:
<a href="http://www.site.com/?subscribe=thegeneratedid">Subscribe</a>
<a href="http://www.site.com/?insubscribe=thegeneratedid">Unsubscribe</a>
当被邀请者单击订阅链接时，服务器将为他设置标志和欢迎消息.如果他已经被订阅，它将显示一条正确的消息.对于取消订阅链接，它的工作原理类似，但是效果相反.
但是我不会在同一封邮件中添加两个链接.邀请只能包含订阅链接，订阅确认邮件可以包含取消订阅链接.

I would proceed like this:
- As every invitation is generated on server, I would generate a long, unique, random ID for them
- I would store the ID in the database along with the invitee data, and a "subscribed" flag
- I would add this id as parameter in the links, like this:
<a href="http://www.site.com/?subscribe=thegeneratedid">Subscribe</a>
<a href="http://www.site.com/?insubscribe=thegeneratedid">Unsubscribe</a>
When the invitee clicks on the subscription link, the server would set the flag for him, and a welcome message. If he is already subscribed, it would display a proper message. And it would work similary for the unsubscribe link, but of course with opposite effect.
But I would not add both links in the same mail. The invitation could contain only the subscribe link, and the subscription confirmation mail could contain the unsubscribe link.
