Resolving Cross-domain access Problems with Serveresource in Liferay

Brief introduction:

It is well known that cross-domain problems are a very common requirement, such as having a client's EXT-JS control render a JSON object from the server side. We can solve them in many ways, such as JSONP. However, in Liferay, we can use the Serveresource method to gracefully resolve Cross-domain access issues.

Whiteboard Analysis:

Here is the whiteboard on the technical symposium:

Workaround:

First write a Serveresource method to deal with the remote JSON object, which can be encapsulated as a middle-tier in the remoting JSON resource, and then provided to the EXT-JS code in this domain to render.

Of course, our resources here must be stated on the page with <portlet:resourceURL/> to allow the client Ext-js to use the specified variable to access the code:

The client, the basic EXT-JS, is able to render the JSON resources we serveresource provide, because it is within this domain, so there is no cross-domain.
