What is the purpose of the change

fix incorrect handling of the URLBuilder caused the wrong URL to be generated

Brief changelog

在appItemToUrls方法中，对services进行遍历的时候，因为复用同一个URLBuilder，没有使用深拷贝，导致所有的值都追加在了一起。

serviceItemToUrls方法中，对apps遍历的时候，也是这个问题。不过因为是追加参数到url，所以后者会覆盖前者，这个并不影响功能，我只是在这个上面和appItemToUrls保持统一。
