问题描述
我正在尝试即时更改 cakephp 3 中使用的数据库连接.我发现的该问题的每个答案都指向 cakephp 2 ( 实例).
I'm trying to change the database connection used in cakephp 3 on the fly. Every answer to this question that I found refers to cakephp 2 (These three for instance).
这个家伙找到了针对 cakephp 3 的解决方案具有有限数量的数据库，并专门定义哪个Table文件将使用哪个数据库.
This guy found a solution for cakephp 3 having a finite number of databases, and specifically defining which Database would be used by which Table file.
问题是，我想为每个新用户创建一个新数据库，并在他登录时更改为他的数据库.我无法事先知道将存在的所有数据库，都必须将其写入文件.
The thing is that I want to create a new database for every new user, and change to his database when he logs in. I can't know in advance all the databases that will exist, to write it in the config/app.php file.
而且我无法在每个/src/Model/Table文件中设置默认数据库，因为每个数据库中的表都相同.
And I can't set the default database in each /src/Model/Table file, because the tables are the same in every database.
推荐答案
使用ConnectionManager::config()函数动态创建连接，并使用ConnnectionManager::alias()方法使所有Table类默认使用它.
Use the ConnectionManager::config() function to create connections on the fly and the ConnnectionManager::alias() method to make all your Table classes use it by default.
这里有一篇很好的文章介绍了该过程:
There is a very good article describing the process here:

唯一的区别是您可以动态创建连接配置，而不是像该文章中所示那样手动声明分片.
The only difference is that you can create the connection config on the fly instead of declaring the shards manually as it was shown in that article.
