The present embodiment provides another method for acquiring virtual resources, which is implemented on the basis of the foregoing embodiments; this embodiment mainly describes a specific implementation manner of performing audit on audit information carried in a virtual resource request. As shown in fig. 2, another flow chart of a virtual resource obtaining method, the virtual resource obtaining method in this embodiment includes the following steps:
step S202, receiving a request for applying virtual resources sent by a teaching terminal;
step S204, extracting the audit information carried in the application request; the auditing information comprises user information corresponding to a user applying for the virtual resource, identification information corresponding to the virtual resource and reservation information applying for the virtual resource;

If the verification of the audit information is passed, i.e. the audit information is correct, the steps S206 to S214 are executed, and if the verification of the audit information is not passed, the steps S216 to S218 are executed.
Step S206, extracting the virtual resource identifier corresponding to the virtual resource carried in the application request and the protocol address corresponding to the teaching terminal;
step S208, determining terminal coordinate information of the position of the teaching terminal based on the protocol address; the terminal coordinate information refers to longitude and latitude of the position where the teaching terminal is located in a world coordinate system;
step S210, determining a target storage node closest to the teaching terminal from a plurality of storage nodes according to the terminal coordinate information;
generally, a support server stores a storage node table in advance, and coordinate information corresponding to each storage node is stored in the storage node table; the coordinate information is the longitude and latitude of the position of the storage node in a world coordinate system; the step S210 can be realized by the steps a1 to a 2:
step A1, calculating the path distance between the teaching terminal and each storage node based on the terminal coordinate information and the coordinate information;
in this embodiment, the terminal coordinate information of the tutorial terminal and the coordinate information of each storage node are known, and therefore, the path distance can be calculated by the following equation:
where d denotes the path distance, x1，y1Representing terminal coordinate information, x2，y2Coordinate information representing the storage node.
In step a2, the storage node with the shortest calculated path distance is determined as the target storage node.
Based on the formula, the path distance between the teaching terminal and each storage node can be calculated, and in this embodiment, a depth or breadth first search algorithm can be applied to search the storage node with the shortest path to the teaching terminal from the plurality of path distances to determine the storage node as a target storage node, so that the virtual resource can be obtained from the target storage node for teaching. The method for searching for the shortest path from the multiple path distances is not limited to the depth-first search algorithm or the breadth-first search algorithm.
Step S212, determining a target virtual resource corresponding to the virtual resource identifier from a plurality of specific virtual resources stored in the target storage node;
in general, a specific virtual resource identifier corresponding to each specific virtual resource is also stored in the storage node; the identification form of the specific virtual resource identification is the same as the identification form of the virtual resource identification carried by the application request. The step S212 can be realized by the steps B1 to B2:
step B1, searching a target specific virtual resource identifier matched with the virtual resource identifier from the plurality of specific virtual resource identifiers;
for example, the plurality of specific virtual resource identifiers are 1, 2, 3, and 4, respectively, where if the virtual resource identifier is 2, the specific virtual resource identifier that is the same as the virtual resource identifier is determined as the target specific virtual resource identifier.
And step B2, determining the target virtual resource corresponding to the virtual resource identification from the specific virtual resource corresponding to the target specific virtual resource identification.
And determining the specific virtual resource corresponding to the target specific virtual resource identifier as the target virtual resource required by the application request, and realizing the virtual simulation experiment of the user by using the target virtual resource.
Step S214, returning the target virtual resource to the teaching terminal;
after the target virtual resource corresponding to the virtual resource identifier is determined from the target storage node through the step S212, the target virtual resource may be returned to the teaching terminal so that the user may complete the virtual experiment according to the target virtual resource.
Step S216, generating error information; wherein, the error information carries the information that the verification fails;
step S218, error information is returned to the teaching terminal;
if at least one information verification in the audit information fails (namely the information is incorrect), error information containing unsuccessful verification is generated and returned to a display interface of the teaching terminal, so that a user can input correct audit information to apply for virtual resources again according to the prompt of the error information.
