Description

Method, equipment and storage medium for dynamically updating software development kit Technical Field Embodiments of the present application relate to the field of data processing technology of financial technology (Fintech), and relate to, but are not limited to, a method, apparatus, and computer-readable storage medium for dynamically updating a software development kit. Background With the development of computer technology, more and more technologies are applied in the financial field, and the traditional financial industry is gradually changed to the financial technology (Fintech), however, the financial technology also has higher requirements on the technology due to the requirements of safety and real-time performance of the financial industry. In the field of financial science and technology, various information can be directly displayed to a user through various application programs on a mobile terminal, and a more common way to display information to a user through an application program is to embed a Software development kit (Software DevelopmentKit, SDK) as a whole into an application. The update of the SDK needs to be performed through the component linker, and each time the update needs to generate a patch, the patch synthesis may fail, and the rollback to the old version may increase the cost. The existing SDK updating mode is to update the SDK by decompressing, repackaging, copying the dex file or the so file. However, this updating method is not only cumbersome, but also is prone to abnormality in the process of operating the file, such as sudden program exit or device power failure, which results in file writing failure, so that the method of copying the dex file or so file to update the SDK is prone to problems, resulting in update failure. Disclosure of Invention The embodiment of the application provides a method, equipment and a computer readable storage medium for dynamically updating a software development kit, which are used for solving the problem that updating failure easily occurs in a mode of updating an SDK by copying a dex file or a so file in the related technology. The technical scheme of the embodiment of the application is realized as follows: The embodiment of the application provides a method for dynamically updating a software development kit, which comprises the following steps: when a host application program is started, determining that a target plug-in included in a software development kit corresponding to the host application program at a tool development end is updated; Copying the updated target plug-in to an engineering catalog of the host application program; And changing a class loading mechanism through a hook, loading the class of the target plug-in the host application program based on the changed loading mechanism, and reflecting a method for calling the class of the target plug-in so as to realize the target plug-in. The embodiment of the application provides equipment, which comprises the following components: the processor is used for realizing the method when executing the executable instructions stored in the memory. The embodiment of the application provides a computer readable storage medium, which stores executable instructions for causing a processor to execute the method. The embodiment of the application has the following beneficial effects: The method comprises the steps of determining that a target plug-in included in a software development tool package corresponding to a host application program of a tool development end is updated when the host application program is started, copying the updated target plug-in to an engineering catalog of the host application program, loading the class of the target plug-in the host application program through a hook changing class loading mechanism, and reflecting and calling the class of the target plug-in to achieve the target plug-in, so that a mode of packaging and copying a dex file of the plug-in to update the SDK is abandoned, the plug-in type SDK is updated, the probability of file operation failure is reduced, the SDK can be split into a plurality of plug-ins, and accordingly updating of the SDK can be achieved in a plug-in type updating mode under the condition that a certain plug-in is updated, and flow of downloading the plug-in and time of integrating the plug-in are saved.
