How does Yii ensure the uniqueness of a URL?

How does Yii ensure the uniqueness of a URL?

For example, we have the following rules:

1	'Post/ '=> 'Post/read ',

The following URLs are valid:

123	Post/read/id/5 post/read? Id = 5 post/5

If we have a suffix, for example. Html, The following URL is valid,

123	Post/read/id/5.html post/read.html? Id = 5 post/5.html

There are 6 URLs in total, which does not match SEO,

The solution is simple. you only need to write the code in your Controller:

12345678

PublicfunctionbeforeAction ($ action) {if (Yii: app ()-> request-> url! = CHtml: normalizeUrl (array_merge (array ($ this-> route), $ _ GET) $ this-> redirect (CHtml :: normalizeUrl (array_merge (array ($ this-> route), $ _ GET), true, 301); returnparent: beforeAction ($ action );}

This will redirect all URL addresses to a specified 'valid Address'. replacing 301 with 302 will make the browser (google robot) know the correct address.

You can write a base class for implementation:

1234567891011121314151617

Request-> url! = CHtml: normalizeUrl (array_merge (array ($ this-> route), $ _ GET) $ this-> redirect (CHtml :: normalizeUrl (array_merge (array ($ this-> route), $ _ GET), true, 301); returnparent: beforeAction ($ action );}}

Tip | you should not use this rule in actionError and actionIndex. Therefore, if you want to use a unique URL for actions in siteController, you should not inherit the base class mentioned above, otherwise, you will use a special method to handle the exceptions generated by both of them.
