Then, if the result of the first detection indicates that the file to be tested includes the code program for remote call, the metadata information corresponding to the file to be tested can be subjected to second detection based on the preset specification features so as to determine whether the file to be tested is an error file.
Specifically, a plurality of target member methods in the file to be tested can be determined based on metadata information corresponding to the file to be tested, wherein the target member methods comprise member variables with preset variable characteristics, and the target member methods are call points for remote call. And judging whether the member method with the preset standard characteristics exists in the target member methods according to each target member method. If it is determined that at least one member method which does not have the preset specification characteristics exists in the target member methods, it may be determined that the file to be tested is an error file. If it is determined that there is no member method having no preset specification feature in the target member methods, it may be determined that the file to be tested is not an error file.
According to the embodiment, whether the file to be tested contains a code program for remote call or not can be judged based on the preset variable characteristics and metadata information corresponding to the file to be tested, and whether the file to be tested is an error file or not is judged based on the preset standard characteristics and the metadata information corresponding to the file to be tested when the file to be tested contains the code program for remote call.

traversing the byte code files, and determining the byte code file as a file to be tested if the identification corresponding to the byte code file is recorded in the file information to be tested for any byte code file.
3. The method of claim 1, wherein the detecting each of the files under test based on the detection rules comprises:
and detecting metadata information corresponding to each file to be detected based on the detection rule by adopting a preset plug-in, wherein the preset plug-in is inserted into a compiling stage of a compiling period of a target program in advance.
4. A program detection apparatus, which is applied to a compile time of a program, the apparatus comprising:
the acquisition module is used for acquiring a plurality of byte code files obtained after compiling the target program;
the determining module is used for determining preset configuration information, wherein the configuration information comprises file information to be detected and detection rules;
the screening module is used for determining a file to be tested in the plurality of byte code files based on the file information to be tested;
the analysis submodule is used for analyzing each file to be tested to obtain metadata information corresponding to each file to be tested;
the detection module is used for detecting each file to be detected based on the detection rule, the detection rule comprises preset variable characteristics and preset standard characteristics, and aiming at any file to be detected, a preset plug-in is adopted to detect metadata information corresponding to the file to be detected in the following mode:
and carrying out first detection on metadata information corresponding to the file to be detected based on the preset variable characteristics:
determining a plurality of member variables of the file to be tested based on metadata information corresponding to the file to be tested; if at least one member variable with the preset variable characteristics exists in the member variables, determining that the file to be tested contains a code program for remote calling; if the result of the first detection indicates that the file to be detected contains a code program for remote calling, performing a second detection on metadata information corresponding to the file to be detected based on the preset specification feature: determining a plurality of target member methods in the file to be tested based on metadata information corresponding to the file to be tested, wherein the target member methods comprise member variables with preset variable characteristics; and if at least one member method which does not have the preset standard characteristics exists in the target member methods, determining that the file to be detected is an error file.
5. The apparatus of claim 4, wherein the detection module comprises:
and the verification sub-module is used for detecting the metadata information corresponding to each file to be detected based on the detection rule by adopting a preset plug-in, and the preset plug-in is inserted into the compiling stage of the compiling period of the target program in advance.
6. A computer-readable storage medium, characterized in that the storage medium stores a computer program which, when executed by a processor, implements the method of any of the preceding claims 1-3.
7. An electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, characterized in that the processor implements the method of any of the preceding claims 1-3 when executing the program.
