Abstract

Cross-domain communication between a sender domain and a receiver domain includes: receiving, in the receiver domain, a data request from the sender domain, the data request being directed to a designated request processing page in the receiver domain; processing the data request to generate a response; and sending the response to the sender domain, the response being directed to a designated response processing page in the sender domain. Alternatively, cross-domain communication includes receiving, in the receiver domain, a data request from the sender domain, the data request being directed to a designated request processing page in the receiver domain; processing the data request to generate a response; and sending the response to the sender domain, the response being directed to a designated response processing page in the sender domain.

Claims

1. A sender system for cross-domain communication between a sender domain and a receiver domain that is different from the sender domain, comprising:

a processor configured to;

send a data request from the sender domain to the receiver domain, the data request being directed to a designated request processing page in the receiver domain;

receive a response from the receiver domain, the response including requested data and being directed to a designated response processing page in the sender domain; and

process the response; and

a memory coupled to the processor, configured to provide the processor with instructions.

2. The system of claim 1, wherein the data request is sent in response to a client action from a browser to an originating webpage in the sender domain.

3. The system of claim 1, wherein the designated request processing page is deployed in the receiver domain and the designated response processing page is deployed in the sender domain prior to the cross-domain communication.

4. The system of claim 1, wherein sending the data request from the sender domain to the receiver domain includes:

opening a hidden page; and

using the hidden page to open the designated response processing page and send a request command and associated request data via the hidden page.

5. The system of claim 4, wherein opening the hidden page includes opening an invisible new window or an invisible iframe.

6. The system of claim 1, wherein the data request includes a request command and associated request data that are sent via a Hypertext Transfer Protocol (HTTP) GET command.

7. The system of claim 1, wherein:

the data request includes a request command and associated request data;

the request command is sent as a fragment identifier attached to a uniform resource locator (URL); and

the associated data are transferred as a name property of a window object.

8. The system of claim 1, wherein:

the data request includes a request command and associated request data;

the request command and the associated request data are sent as a fragment identifier attached to a URL.

9. The system of claim 1, wherein request is transferred as a string in JSON format.

10. A method for cross-domain communication between a sender domain and a receiver domain that is different from the sender domain, comprising:

sending a data request from the sender domain to the receiver domain, the data request being directed to a designated request processing page in the receiver domain;

receiving a response from the receiver domain, the response including requested data and being directed to a designated response processing page in the sender domain; and

processing the response.

11. A receiver system for cross-domain communication between a sender domain and a receiver domain that is different from the sender domain, comprising:

a processor configured to;

receive, in the receiver domain, a data request from the sender domain, the data request being directed to a designated request processing page in the receiver domain;

process the data request to generate a response; and

send the response to the sender domain, the response being directed to a designated response processing page in the sender domain; and

a memory coupled to the processor, configured to provide the processor with instructions.

12. A method for cross-domain communication between a sender domain and a receiver domain that is different from the sender domain, comprising:

receiving, in the receiver domain, a data request from the sender domain, the data request being directed to a designated request processing page in the receiver domain;

processing the data request to generate a response; and

sending the response to the sender domain, the response being directed to a designated response processing page in the sender domain.

13. A receiver system for cross-domain communication between a sender domain and a receiver domain that is different from the sender domain, comprising:

a processor configured to;

receive, in the receiver domain, a data request from the sender domain, the data request being directed to a designated request processing page in the receiver domain;

process the data request to generate a response; and

send the response to the sender domain, the response being directed to a designated response processing page in the sender domain; and

a memory coupled to the processor, configured to provide the processor with instructions.
