The URL of the U method is automatically updated based on the route configuration.

Provides various official and user-released code examples. For code reference, you are welcome to exchange and learn about the U method and automatically update the address based on the route configuration.
You can see it on the Internet. I don't know about Mars.
Modify Common \ functions. php If (! Empty ($ vars) {// Add Parameters
Foreach ($ vars as $ var => $ val ){
If (''! = Trim ($ val) $ url. = $ depr. $ var. $ depr. urlencode ($ val );
}Add the following code: (replace GROUP_NAME with MODULE_NAME in version 3.2) /*
* When tp enables a route entry, the next route entry becomes invalid. Paging URL assembly

*/
// If routing is enabled
If (C ('url _ ROUTER_ON ')){
Foreach (C ('url _ ROUTE_RULES ') as $ zhaolg => $ zlig) {// traverse the route
If (strstr ('/'. GROUP_NAME. $ url, $ zlig) {// find routing rules from the url
$ Lg = strstr ($ zhaolg, '/:'); // does the analysis rule contain parameters?
If ($ lg) {// if the rule contains Parameters
$ Tempzlg = str_replace ('/:', ', $ lg); // obtain the Parameter
// Dump ($ tempzlg );
If ($ tempzlg ){
If (C ('app _ SUB_DOMAIN_DEPLOY ')){
$ Zlgurl = str_replace ($ zlig, $ zhaolg, '/'. GROUP_NAME. $ url); // Replace the url with the routing rule
} Else {
$ Zlgurl = str_replace ($ zlig, $ zhaolg, $ url); // Replace the url with the routing rule
}
// Note/s/: c/4/p/_ PAGE __
// Dump ($ zlgurl );
$ Url = str_replace ($ lg. '/'. $ tempzlg, '', $ zlgurl); // replace routing rule parameters with URLs

}
} Else {// The analysis rule does not contain parameters
If (C ('app _ SUB_DOMAIN_DEPLOY ')){
$ Url = str_replace ($ zlig, $ zhaolg, '/'. GROUP_NAME. $ url); // Replace the url with the routing rule
} Else {
$ Url = str_replace ($ zlig, $ zhaolg, $ url); // Replace the url with the routing rule
}

}
}
}
}After the preceding modification, you do not need to manually modify the U method based on the routing rules. This makes it easier to update routing rules without modifying the template file.
According to my test, nginx is invalid and apache is valid.
