1.dojo/request/script：跨域

dojo/request/script is a provider that uses dynamic <script> tags to make requests and receive responses. It is typically used when cross-domain requests need to be made.

2.dojo/request/xhr：默认的

dojo/request/xhr is a provider that uses XMLHttpRequest (XHR) <https://developer.mozilla.org/en/DOM/XMLHttpRequest> objects to make asynchronous requests. It is the default provider for browser based platforms.
