Description
Technical Field

Background
For multi-Web system integration, in some specific cases, the service to be accessed needs to initiate a request to a third party service.
Single sign-on integration is a common integration technology, and OAuth (Open Authorization) can implement single sign-on integration. OAuth provides a secure, open and simple standard for authorization of user resources, and a third party can apply for authorization of the user resources without using a user name and password of the user, and OAuth2 is a second version of OAuth. As shown in fig. 1, in the network interaction process of OAuth2, steps 6 and 8 are to require the service to be accessed to initiate a request to the third party service. In the prior art, two interaction modes for actively initiating a request to a third-party server are mainly used, the first mode is to directly access the third-party server when the third-party server needs to be accessed, but the method is applicable to the mode and cannot partition a network structure by the server according to functions and permissions. The second approach is to access the third-party server uniformly through one proxy server, but this approach cannot logically separate networks of different partitions. In the prior art, a service processing part of a service party to be accessed needs to send a request outwards, and the network security is poor.

An eighth embodiment of the present invention further provides a storage medium containing computer-executable instructions, which when executed by a computer processor, perform a method for requesting a preamble, the method including:
the centralized node responds to a data acquisition request sent by the front-end processor, and locally inquires whether data to be requested sent by a service processing party is stored at present;
if so, the centralized node sends the data to be requested to the front-end processor so that the front-end processor requests a response service to a third-party server according to the data to be requested, wherein the front-end processor is used for isolating direct communication between the centralized node and the third-party server;
and the centralized node receives response result data of the data to be requested, which is acquired by the front-end processor from the third-party server, and provides the response result data to the service processing party.
The computer-executable instructions, when executed by a computer processor, are further operable to perform a method of requesting a preamble, the method comprising:
the front-end processor sends a data acquisition request to a centralized node, wherein the data acquisition request is used for indicating the centralized node to locally inquire whether to-be-requested data sent by a service processing party is stored;
if the front-end processor receives the data to be requested fed back by the centralized node, the front-end processor sends the data to be requested to a third-party server for requesting response service, wherein the front-end processor is used for isolating direct communication between the centralized node and the third-party server;
and the front-end processor sends response result data fed back by the third-party server aiming at the data to be requested to the centralized node so that the centralized node provides the response result data to the service processing party.
Of course, the storage medium provided by the embodiment of the present invention contains computer-executable instructions, and the computer-executable instructions are not limited to the method operations described above, and may also perform related operations in the method for requesting a preamble provided by any embodiment of the present invention.
From the above description of the embodiments, it is obvious for those skilled in the art that the present invention can be implemented by software and necessary general hardware, and certainly, can also be implemented by hardware, but the former is a better embodiment in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which may be stored in a computer-readable storage medium, such as a floppy disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a FLASH Memory (FLASH), a hard disk or an optical disk of a computer, and includes several instructions for enabling a computer device (which may be a personal computer, a server, or a network device) to execute the methods according to the embodiments of the present invention.
It should be noted that, in the embodiment of the device for requesting a front end, the included units and modules are only divided according to functional logic, but are not limited to the above division as long as the corresponding functions can be implemented; in addition, specific names of the functional units are only for convenience of distinguishing from each other, and are not used for limiting the protection scope of the present invention.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
