Multiple URLs in proxy

How can I use multiple URLs in a proxy in E开发者_StackOverflowxtjs 4?

Proxy:{
        url:'?'
      }

Thanks

storename.getProxy().url='your-url'

in your store:

proxy: {        
      type: 'ajax',
      api: {
       read: '/controller/read',
       update: '/controller/update',
       create: '/controller/create'
     },
    ....
