To solve the problem, an information processing method provided by an embodiment of the present invention includes: and adding an information injection area for injecting additional information in the installation package file, and directly writing the additional information in the information injection area on the premise of changing the format of the installation package file.
In order to make those skilled in the art better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a flowchart of an information processing method according to an embodiment of the present invention is shown, where the information processing method is used to inject additional information into an installation package file, and one of core ideas of the method is as follows: an information injection area for writing additional information is added in the installation package file, and the additional information is directly written in the information injection area on the premise of changing the file format of the installation package, which specifically comprises the following steps:
101: a compressed source file data area, a compressed source file directory ending area and an annotation area are sequentially formed in the installation package file, and an information injection area with a preset capacity is established behind the annotation area.
The compressed source file data area is used for storing program codes in the installation package file and configuration information required by the installation process; the compressed source file directory area is used for recording an installation directory of information stored in the compressed source file data area; the compressed source file directory ending area is the end of the compressed source file directory area and indicates the termination of the recorded installation directory; the comment area is used for recording the description information of the installation package file.
The compressed source file data area, the compressed source file directory ending area and the comment area are in the format of the current installation package file. In order to reduce the difficulty of injecting additional information into the installation package file, the embodiment of the invention changes the format of the installation package file, and the change mode can be as follows: an information injection area is established after the annotation area. The modified installation package file format is shown in table 1.
TABLE 1 installation Package File Format
The data capacity of the information injection region is preset when the information injection region is established, that is, the information injection region has a predetermined capacity, and the configuration of the predetermined capacity of the information injection region in the embodiment of the present invention includes, but is not limited to, the following two ways:
one is to configure a fixed capacity in the information injection region, and the other is to configure a predetermined capacity in the information injection region according to the capacity occupied by the actually added additional information, specifically, to configure a predetermined capacity in the information injection region, which is larger than the capacity occupied by the received additional information.
102: additional information that needs to be injected into the installation package file is received.
103: additional information is written into the information injection area.
On the premise of changing the file format of the installation package, after the additional information is received, the additional information can be directly written into the information injection area added in the installation package file. Therefore, on the premise of changing the file format of the installation package, the mode of writing the additional information is convenient, and compared with the mode of adding the additional information by researching, developing and integrating the SDK, the development difficulty is reduced.
The compressed source file data area, the compressed source file directory area and the compressed source file directory ending area serve as three independent areas in the installation package file, each independent area has identification information as an area header to identify the area, and the identification information specifically includes: the compressed source file data area comprises first identification information, the compressed source file directory area comprises second identification information, the compressed source file directory ending area comprises third identification information, and the first identification information, the second identification information and the third identification information are all different. For example, the first identification information is: 0x04034b50, and the second identification information is: 0x02014b50, and the third identification information is: 0x02014b 50.
When writing the additional information into the information injection area, the information processing method provided in the embodiment of the present invention further needs to compare the additional information with the identification information of each independent area, so as to avoid writing the additional information that is the same as the identification information into the information injection area. Since writing the additional information identical to the identification information into the information injection area may cause an identification error of the installation package file, the additional information and the identification information are compared first before writing the additional information, and a specific process may be shown in fig. 2, and may include the following steps:
201: a compressed source file data area, a compressed source file directory ending area and an annotation area are sequentially formed in the installation package file, and an information injection area with a preset capacity is established behind the annotation area. The compressed source file data area, the compressed source file directory area and the compressed source file directory ending area respectively comprise first identification information, second identification information and third identification information.
202: additional information that needs to be injected into the installation package file is received.
In the embodiment of the present invention, step 201 and step 202: this embodiment of the present invention is not described again, as in steps 101 and 102 of fig. 1.
203: and comparing the additional information with each identification information to obtain a comparison result.
204: and writing the additional information into the information injection area when the comparison result shows that the additional information and each piece of identification information are different.
205: when the comparison result shows that the additional information is the same as any one of the identification information, prompt information is sent, and the prompt information is used for indicating that the additional information needs to be modified, so that the additional information which is the same as the identification information can be prevented from being written into the information injection area, and the identification of the installation package file is enabled to be wrong.
