Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0059] It should be noted that the concepts such as "first" and "second" mentioned in the present application are only used to distinguish different devices, modules or units, and are not used to limit the order or mutual dependence relationship of the functions performed by these devices, modules or units. The terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0060] The embodiments of the present application provide a method for previewing the content of a QR code, as Figure 1 shown, specifically including:

[0061] S101. The client obtains at least one QR code obtained by scanning a target area.

[0062] S102. For each QR code, the client identifies the string in the QR code.

[0063] S103. The client sends the strings in all the QR codes to the server.

[0064] For each string, the server analyzes the string to obtain an analysis result of the string; the analysis result of the string at least includes: the risk level of the string and the content type of the string.

[0065] S104. The server receives at least one string sent by the client.

[0066] S105. For each string, the server analyzes the string to obtain an analysis result of the string.

[0067] Among them, the analysis result of the string includes at least: the risk level of the string and the content type of the string. The risk level of the string can represent the risk level of the QR code to which the string belongs. The content type of the string can be understood as what kind of content can be obtained after opening the QR code to which the string belongs, such as text, picture, video, audio, installed software, etc., which is not limited here.

[0068] It should be noted that the risk level can be divided into high, medium, low, or A, B, C, D, etc., and the methods are very diverse, which are not limited here.

[0069] And it can be understood that in the specific implementation process of this application, not only the risk level can be displayed, but also a sensitivity can be set to more specifically show the content situation in the QR code.

[0070] Optionally, in another embodiment of this application, an implementation manner of step S105 is as Figure 2 shown, including:

[0071] S201. For each string, decrypt the string to obtain the plaintext uniform resource locator information.

[0072] It should be noted that a specific format is agreed upon when generating the QR code, such as starting with boc: / / , and then generating the QR code. After identifying the QR code, decrypt the string (such as querying and then replacing), and decrypt it into the plaintext uniform resource locator information (Uniform Resource Locator, URL).

[0073] S202. Query in the database to obtain the risk level of the plaintext uniform resource locator information.

[0074] Among them, the risk level of the plaintext uniform resource locator information is used to indicate the risk level of the string.

[0075] S203. Crawl the target content in the link corresponding to the plaintext uniform resource locator information.

[0076] Among them, the target content includes at least: the content type, and can also include the web page name, etc., which can be set and changed by technicians or relevant authorized personnel according to actual needs, which is not limited here.

[0077] S204. Generate the analysis result of the string according to the risk level and content type of the string.

[0078] S106. The server side feeds back the analysis result of each string to the client side.

[0079] S107. The client side receives the analysis result of each string fed back by the server side.

[0080] S108. The client generates an augmented reality card corresponding to the string based on the analysis result of each string.

[0081] Among them, the augmented reality card at least includes: the analysis result of the string; the augmented reality (AR) card corresponding to the string is located next to the two-dimensional code to which the string belongs, and it is indicated by guidance that the augmented reality card corresponding to the string is the preview content of the two-dimensional code to which the string belongs.

As Figure 3 shown, it is a schematic diagram of an image obtained when a user scans a target area using a mobile application.

It can be seen that the user can select the target two-dimensional code to be selected according to the content displayed by the augmented reality card, and effectively avoid selecting a two-dimensional code with a higher risk, thereby bringing unnecessary security hazards.
