Abstract

Techniques for manipulating URIs that have been rewritten for XmlHttpRequests (XHRs) and/or Web Services for Remote Portlets (WSRP). In one set of embodiments, a URI rewriter factory module is provided that is configured to determine and select a URI rewriter module based upon an input URI string. The input URI string may be, for example, in the form of a Javascript pseudo-protocol link, a remote proxy URI, or both. The selected URI rewriter module can then parse the input URI string to generate a URI object that has methods for manipulating the input URI string and for outputting the resulting manipulated URI as a string.

Claims

1. A computer-implemented method for manipulating a uniform resource identifier (URI), the method comprising:

receiving, at a processing system, an input string, wherein the input string includes at least one rewritten URI string that has been rewritten from an original URI string form;

interacting, at the processing system, with a plurality of URI rewriters to select a URI rewriter, wherein the interacting includes;

calling a function associated with each of the plurality of URI rewriters,

receiving a response from a first URI rewriter indicating that the first URI rewriter recognizes a format of the at least one rewritten URI string based on the first URI rewriter executing the function,

determining that the first URI rewriter is operable to parse the at least one rewritten URI string, and

selecting the first URI rewriter among the plurality of URI rewriters;

providing the at least one rewritten URI string to the selected URI rewriter, wherein the selected URI rewriter parses the at least one rewritten URI string to generate a URI manipulator corresponding to the at least one rewritten URI string, wherein the URI manipulator is configured to return at least one URI string associated with the at least one rewritten URI string, wherein the at least one URI string is in the original URI string form; and

performing, at the processing system, one or more operations on portions of the at least one URI string in the original URI string form using the URI manipulator.

2. The method of claim 1 wherein the format is a format used to support XmlHttpRequests (XHRs).

3. The method of claim 1 wherein the input string is encoded as a Javascript pseudo-protocol link or a proxy URI.

4. The method of claim 1 further comprising parsing the input string by the URI rewriter to identify the at least one rewritten URI string included in the input string.

5. The method of claim 1 wherein parsing the at least one rewritten URI string comprises parsing a Javascript pseudo-protocol link to identify at least one URI string included in the Javascript pseudo-protocol link.

6. The method of claim 1 wherein parsing the at least one rewritten URI string comprises parsing a proxy URI string to identify a target URI string included in the proxy URI string, wherein the target URI string is a non-proxy URI string.

7. The method of claim 4 wherein parsing the input string comprises returning the input string.

8. The method of claim 1 wherein the one or more Operations performed on portions of the at least one URI string comprises parsing the at least one URI string, replacing template keys with values in the at least one URI string, and performing create, read, update, and delete operations on one or more components of the at least one URI string.

9. The method of claim 1 wherein the selected URI rewriter is configured to parse the input string to identify the at least one rewritten URI string.

10. The method of claim 1, wherein the format is a format used to support Web Services for Remote Portlets (WSRP).

11. A non-transitory computer-readable storage medium storing a plurality of instructions for manipulating a uniform resource identifier (URI), the plurality of instructions comprising:

instructions that cause the processor to receive an input string, wherein the input string includes at least one rewritten URI string that has been rewritten from an original URI string form;

instructions that cause the processor to interact with a plurality of URI rewriters to select a URI rewriter, wherein the instructions cause the processor to

call a function associated with each of the plurality of URI rewriters,

receive a response from a first URI rewriter indicating that the first URI rewriter recognizes a format of the at least one rewritten URI string based on the first URI rewriter executing the function,

determine that the first URI rewriter is operable to parse the at least one rewritten URI string, and

select the first URI rewriter among the plurality of URI rewriters;

instructions that cause the processor to provide the at least one rewritten URI string to the selected URI rewriter, wherein the selected URI rewriter parses the at least one rewritten URI string to generate a URI manipulator corresponding to the at least one rewritten URI string, wherein the URI manipulator is configured to return at least one URI string associated with the at least one rewritten URI string, wherein the at least one URI string is in the original URI string form; and

instructions that cause the processor to perform one or more operations on portions of the at least one URI string in the original URI string form using the URI manipulator.

12. The non-transitory computer-readable storage medium of claim 11 wherein the format is a format used to support XmlHttpRequests (XHRs) or Web Services for Remote Portlets (WSRP).

13. The non-transitory computer-readable storage medium of claim 11 wherein the input string is encoded as a Javascript pseudo-protocol link or a proxy URI.

14. The non-transitory computer-readable storage medium of claim 11 further comprising instructions that cause the processor to parse the input string to identify the at least one rewritten URI string included in the input string.

15. The non-transitory computer-readable storage medium of claim 11 wherein the instructions that cause the processor to parse the at least one rewritten URI string comprise instructions that cause the processor to parse a Javascript pseudo-protocol link to identify at least one URI string included in the Javascript pseudo-protocol link.

16. The non-transitory computer-readable storage medium of claim 11 wherein the instructions that cause the processor to parse the at least one rewritten URI_string comprise instructions that cause the processor to parse a proxy URI string to identify a target URI string included in the proxy URI string, wherein the target URI string is a non-proxy URI string.

17. The non-transitory computer-readable storage medium of claim 14 wherein the instructions that cause the processor to parse the input string comprise instructions that cause the processor to return the input string.

18. The non-transitory computer-readable storage medium of claim 11 wherein the one or more operations performed on portions of the at least one URI string comprises parsing the at least one URI string, replacing template keys with values in the at least one URI string, and performing create, read, update, and delete operations on one or more components of the at least one URI string.

19. A system for manipulating a uniform resource identifier (URI), the system comprising:

a memory configured to store an input string; and

a processor coupled to the memory, wherein the processor is configured to;

receive an input string, wherein the input string includes at least one rewritten URI string that has been rewritten from an original URI string form;

interact with a plurality of URI rewriters to select a URI rewriter, wherein the processor is configured to;

call a function associated with each of the plurality of URI rewriters,

receive a response from a first URI rewriter indicating that the first URI rewriter recognizes a format of the at least one rewritten URI string based on the first URI rewriter executing the function,

determine that the first URI rewriter is operable to parse the at least one rewritten URI string, and

select the first URI rewriter among the plurality of URI rewriters;

provide the at least one rewritten URI string to the selected URI rewriter, wherein the selected URI rewriter parses the at least one rewritten URI string to generate a URI manipulator corresponding to the at least one rewritten URI string, wherein the URI manipulator is configured to return at least one URI string associated with the at least one rewritten URI string, wherein the at least one URI string is in the original URI string form; and

perform one or more operations on portions of the at least one URI string in the original URI string form using the URI manipulator.
