Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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.
The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic flowchart of a method for determining a server identifier corresponding to an application installation package according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 102: and obtaining the source code of the application installation package by performing decompiling on the application installation package.
Step 104: determining a server identifier from the source code; the server identification includes at least one of a server domain name and a server IP address.
Step 106: determining the reference condition of the source code to the variable corresponding to the determined server identifier;
step 108: and determining the server identifier corresponding to the application installation package according to the reference condition and the determined server identifier.
In the embodiment of the present invention, the application installation package of the application may be obtained first, and then the source code of the application installation package may be obtained by performing decompiling on the obtained application installation package.
In an example, when the application installation package of the application is obtained, the application installation package can be obtained by downloading from an application store, and since the content is the prior art, the description of the example is omitted here.
After the application installation package of the application is obtained, the obtained application installation package can be decompiled. In one example, the retrieved application may be an android operating system based application. The following describes the decompilation process of the obtained application installation package in detail by taking an application as an example based on an android operating system:
in an example, after the application installation package of the application is obtained, the obtained application installation package may be decompressed to obtain class.
In the embodiment of the present invention, after the source code of the application installation package is obtained, a server identifier may be determined from the obtained source code, where the server identifier may include at least one of a server domain name and a server IP address.
In one embodiment, the server identification may be determined from the derived source code by a pre-set regular expression. Specifically, the regular expression may be determined according to a composition rule of the server domain name and the server IP address, then, the character string in the source code may be matched according to the determined regular expression, and when the character string in the source code is successfully matched with the determined regular expression, the character string may be determined as the server identifier.
In an example, when a character string in a source code is successfully matched with a determined regular expression, information such as a packet name and a storage path of a packet in which a source file appears in the character string may be obtained, and the obtained information is recorded.
It should be noted that the package (package) involved in the embodiment of the present invention may provide a mechanism for distinguishing name spaces of classes for JAVA, may be an organization manner of the classes, and may be a set of related classes and interfaces, and the package involved in the embodiment of the present invention may provide a management mechanism for access rights and naming.
When information such as a package name and a storage path of a package in which a source file in which the character string appears is located is obtained, the information may be obtained from a source code of an application installation package of the application, or may be obtained from a specified configuration file of the application, where the specified configuration file of the application may include a file in an xml format and a file in a properties format in the configuration file of the application.
In the embodiment of the present invention, after the server identifier is determined from the source code, a reference condition of the source code to the variable corresponding to the determined server identifier may be determined. The variable corresponding to the determined server identifier may be a variable pointed by the determined server identifier when the assignment operation is performed.
For example, the determined server identification may be: www.abc.com, the code where the server ID is located may be: if public String host is "www.abc.com", then as known from the content of the piece of code, the server identifier is assigned, and at this time, the variable pointed to by the assignment operation can be determined from the piece of code: host, so the variable host pointed to by the assignment operation can be determined as the variable corresponding to the server identifier www.abc.com.
It should be noted that, in the prior art, whether the server identifier is assigned according to the code may be identified, and therefore, the embodiment of the present invention is not described herein again.
In the embodiment of the present invention, after determining the variable corresponding to the determined server identifier, a reference condition of the source code to the variable corresponding to the determined server identifier may be determined.
In one embodiment, the reference of the source code to the variable corresponding to the determined server identifier may include at least one of: determining whether the variable corresponding to the server identification is quoted by the source code; whether the package name of the package where the source code of the reference variable is positioned is related to the package name of the application installation package or not.
In one example, when determining whether the variable corresponding to the determined server identifier is referred to by the source code, it may be determined whether the variable corresponding to the determined server identifier is referred to by the code in one or some of the packages in the source code, for example, the source code may include the code: if public String host is "www.abc.com", after www.abc.com is determined as the server identifier and host is determined as the variable corresponding to the server identifier, it may be determined whether the variable host is referred to by the code in the certain package or packages in the source code, and specifically, whether the attribute name of the variable host is referred to by the code in the certain package or packages in the source code.
In another example, when determining whether the variable corresponding to the determined server identifier is referred to by the source code, it may be determined whether the variable corresponding to the determined server identifier is referred to by a code in a certain package or certain packages in an application configuration file, for example, a configuration file named "conf. Www.def.com, after www.def.com is determined as the server identifier and the host is determined as the variable corresponding to the server identifier, it may be determined whether the variable host is referred to by the code in the package or packages in the application configuration file, and specifically, whether the attribute name of the variable host is referred to by the code in the package or packages in the application configuration file.
In another example, when determining whether the package name of the package in which the source code of the reference variable is located is related to the package name of the application installation package, the package name of the application installation package and the package name of the package in which the source code of the reference variable is located may be extracted from the source code, and then, it may be determined whether the two package names are related.
When the package name of the application installation package is extracted from the source code, the package name can be extracted through a preset regular expression. Specifically, the package name of the application installation package can be extracted from a specified package in the source code of the application installation package, such as a package with the name of "android manifest" and format of xml, by a preset regular expression.
For example, as shown in fig. 2, as can be seen from fig. 2, on the manifest node in the application installation package, the attribute package identifies the package name of the application installation package, and at this time, the package name of the application installation package can be identified as com.
Since the technology of matching and extracting the package name of the application installation package by the regular expression is the prior art, the description of this example is omitted here.
In this example, the packet name of the packet in which the source code of the reference variable is located may also be determined by using a preset regular expression, where the regular expression used to determine the packet name of the application installation packet may be the same as or different from the regular expression used to determine the packet name of the packet in which the source code of the reference variable is located.
After determining the package name of the package in which the source code of the reference variable is located and the package name of the application installation package, it may be determined whether the two package names are related, where when determining whether the two package names are related, the determination may be performed according to a preset determination rule, and in one example, the preset determination rule may be determined based on at least one of the following: the second-level package name of the package where the source code of the reference variable is located and the application installation package; and the source code of the reference variable is positioned in the package and the third-level package name of the application installation package.
In one example, the preset determination rule may specifically be: when the package where the source code of the reference variable is located is the same as the second-level package name of the application installation package, determining that the two package names are related; and when the package where the source code of the reference variable is located is not identical to the secondary package name of the application installation package, determining that the two package names are not related.
In another example, the preset determination rule may specifically be: when the package where the source code of the reference variable is located is the same as the third-level package name of the application installation package, determining that the two package names are related; and when the package in which the source code of the reference variable is positioned is different from the third-level package name of the application installation package, determining that the two package names are not related.
In another example, the preset determination rule may specifically be: when the package where the source code of the reference variable is located is the same as the second-level package name or the third-level package name of the application installation package, determining that the two package names are related; and when the source code of the reference variable is in the package, the second-level package name and the third-level package name of the application installation package are different, determining that the two package names are not related.
In another example, the preset determination rule may further specifically be: when the package where the source code of the reference variable is located is the same as the second-level package name and the third-level package name of the application installation package, determining that the two package names are related; and when the package where the source code of the reference variable is located is not identical to the second-level package name and the third-level package name of the application installation package, determining that the two package names are not related.
In the embodiment of the present invention, after determining the reference condition of the source code to the variable corresponding to the determined server identifier, the server identifier corresponding to the application installation package may be determined according to the determined reference condition and the determined server identifier.
In one embodiment, the reference of the determined source code to the variable corresponding to the determined server identifier may include: and if the variable corresponding to the determined server identifier is not referred by the source code, at this time, the server identifier corresponding to the variable which is not referred by the source code can be filtered from the determined server identifier, and then the server identifier corresponding to the application installation package is determined according to the residual server identifiers after filtering.
The source code of the application installation package may include a server identifier that a corresponding variable does not refer to by the source code, for example, a server identifier that is annotated, a server identifier used in a development or test phase, and the like, where the server identifier that the corresponding variable does not refer to by the source code is present in the source code, but the corresponding variable is not referred to by any valid code in the source code, so that the application cannot communicate with the server based on the server identifier that the corresponding variable does not refer to by the source code when running, and therefore the server identifier that the corresponding variable does not refer to by the source code is not the server identifier that the application installation package corresponds to, in the embodiment of the present invention, when determining the server identifier that the application installation package corresponds to, the server identifier that the corresponding variable does not refer to by the source code needs to be filtered out first, and then, determining the server identification corresponding to the application installation package from the residual server identifications after filtering.
In another embodiment, the reference of the determined source code to the variable corresponding to the determined server identifier may include: and if the packet name of the packet in which the source code of the reference variable is located is not related to the packet name of the application installation packet, filtering the server identification corresponding to the variable referenced by the source code from the determined server identification, and then determining the server identification corresponding to the application installation packet according to the residual server identification after filtering.
For example, the partial code in one package of source code may be as shown in FIG. 3, and then the code shown in FIG. 3 may determine that the server identifies http:// api. zhongtouda. com, and that the server identifies the corresponding variable URL, and the partial code in one package of source code may be as shown in FIG. 4, and then the variable URL referred to by the code shown in FIG. 4.
After determining that the variable URL corresponding to the server identifier http:// api. zhongtouda. com is referred, the packet name of the packet where the source code referring to the variable URL is located may be determined, as can be seen from fig. 4, the packet name of the packet where the source code referring to the variable URL is located is com. zhongrongtongdai. ui, as can be seen from fig. 3, the packet name of the application installation packet is com. zhongrongtongdai. tools, and then the two packet names may be determined, and the two packet names have the same secondary packet name and different tertiary packet names, if the preset determination rule is: when the package where the source code of the reference variable is located is the same as the second-level package name of the application installation package, determining that the two package names are related, and determining that the two package names are related because the second-level package names of the two package names are the same and are both zhongrongtongdai; if the preset judgment rule is as follows: when the package where the source code of the reference variable is located is the same as the three-level package names of the application installation package, determining that the two package names are related, and determining that the two package names are unrelated because the three-level package names of the two package names are different, namely ui and tools; if the preset judgment rule is as follows: when the package where the source code of the reference variable is located is the same as the second-level package name or the third-level package name of the application installation package, determining that the two package names are related, and determining that the two package names are related because the second-level package names of the two package names are the same; if the preset judgment rule is as follows: when the package where the source code of the reference variable is located is the same as the second-level package name and the third-level package name of the application installation package, it is determined that the two package names are related, and then since the second-level package names of the two package names are the same and the third-level package names are different, it can be determined that the two package names are unrelated.
In this example, if the two determined package names are not related, the server identifier http:// api. zhongtouda. com corresponding to the variable URL referred by the source code may be filtered, and the server identifier corresponding to the application installation package is determined from the remaining server identifiers after filtering; if the two determined package names are related, the server identification corresponding to the application installation package can be determined according to the server identification http:// api.
As shown in fig. 5, the application may communicate with the server of the application when running, or may simultaneously communicate with at least one third-party server providing the service. The application can communicate with at least one third-party server during running, so that in the source code of the application installation package of the application, the server identifier corresponding to the third-party server is possibly determined as the server identifier, and the corresponding variable is also quoted.
Since the third-party server is not the server of the application, the package name of the package in which the code of the variable corresponding to the server identifier of the third-party server is located is referred to, although the package name of the application installation package of the application corresponding to the third-party server is related to the package name of the application installation package of the application, the package name of the application installation package is not related to the package name of the application installation package, and therefore, the server identifier of the third-party server can be filtered when the server identifier corresponding to the application installation package is determined.
In an embodiment of the present invention, when the server identifier is determined from the source code, a server domain name may be determined, and when the server identifier corresponding to the application installation package is determined according to the reference condition and the determined server identifier, the server domain name corresponding to the application installation package may be determined according to the reference condition and the determined server identifier, and then, a server IP address corresponding to the application installation package may be determined according to the determined server domain name, and the server identifier corresponding to the application installation package may be determined according to the determined server domain name and the determined server IP address.
In one example, the server identification corresponding to the application installation package can include a server IP address corresponding to the application installation package and a server domain name corresponding to the application installation package. When the server identifier corresponding to the application installation package is determined according to the server identifier corresponding to the application installation package and the server IP address corresponding to the application installation package, the server domain name corresponding to the application installation package and the server IP address corresponding to the application installation package may be directly determined as the server identifier corresponding to the application installation package.
When the server IP address corresponding to the application installation package is determined according to the determined server domain name, the IP addresses returned when a plurality of devices access the determined server domain name may be obtained first, and when the plurality of devices access the determined server domain name, the plurality of devices may access the determined server domain name at the same time.
In the embodiment of the invention, when the IP addresses returned when a plurality of devices access the server domain name are obtained, the IP addresses returned when the plurality of devices access the server domain name through a ping command can be obtained; if the device corresponding to the server domain name forbids the ping command, the IP addresses returned by the multiple devices when accessing the server domain name by running a browser driver plug-in, such as a chromedriver plug-in, can be obtained. Specifically, the multiple devices may dynamically access the server domain name by running a browser driver plug-in, perform packet capture processing on communication data of the server domain name, and then may identify a server IP address corresponding to the server domain name from captured data packets.
In another embodiment of the present invention, when the server identifier is determined from the source code, the server IP address may be determined, and when the server identifier corresponding to the application installation package is determined according to the reference condition and the determined server identifier, the server IP address corresponding to the application installation package may be determined according to the reference condition and the determined server identifier, and then the server domain name corresponding to the application installation package may be determined according to the determined server IP address, and the server identifier corresponding to the application installation package may be determined according to the determined server domain name and the determined server IP address.
Since the technology of determining the server domain name according to the server IP address is the prior art, the description of this embodiment is omitted here.
In this embodiment of the present invention, after determining the server identifier corresponding to the application installation package, the obtained server identifier may be stored, and in an example, the server identifier corresponding to the installation package may be stored according to a preset storage format, where the preset storage format may include the following contents: a packet name of a packet in which a source code of a variable corresponding to a server identifier corresponding to the application installation packet is referenced, an MD5(MD5Message-Digest Algorithm, MD5Message Digest Algorithm) value of the source code, a server domain name corresponding to the application installation packet, and a server IP address corresponding to the application installation packet.
For example, the preset storage format may be as shown in table 1:
TABLE 1
In the embodiment of the invention, the source code of the application installation package can be obtained by decompiling the application installation package, the server identifier is determined from the source code, then, the reference condition of the source code to the variable corresponding to the determined server identifier can be determined, and the server identifier corresponding to the application installation package is determined according to the reference condition and the determined server identifier.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately.
