[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The present application solution can be implemented based on a terminal with data processing capabilities, which can be a computer, server, cloud, etc.

[0049] Next, combine Figure 1 The method for comparing parameters of commodities based on search links of the present application may include the following steps:

[0050] Step S110 : responding to the link comparison request of the target product based on the new function search link, calling the id of the old function search link to be compared with the new function search link.

[0051] Specifically, the id of each search link is unique, and the new function search link also has its search link id, so the id of the new function search link is different from the id of the old function search link.

[0052] Step S120: Determine the input and output parameters of the target product at each stage in the new function search link according to the ID of the new function search link.

[0053] Specifically, the new function search link may include, in order of upstream and downstream, an intent recognition stage, a recall details stage, a filtering details stage, a coarse sorting algorithm stage, a fine sorting stage, and a re-sorting strategy stage.

[0054] Step S130: Determine the input and output parameters of the target product at each stage in the old function search link according to the ID of the old function search link.

[0055] Specifically, the stages included in the old function search link are the same as the stages included in the new function search link, and the upstream and downstream order of the stages in the old function search link is also the same as the upstream and downstream order of the stages in the new function search link.

[0056] Step S140: For the input and output parameters of each stage in the new function search link, the input and output parameters of the stage are deserialized from the data sequence of the PB protocol to obtain the deserialization result of the input and output parameters of the stage.

[0057] Among them, the PB protocol is the Protocol Buffers protocol.

[0058] It is understandable that the Protocol Buffers protocol uses a binary format for data serialization, which has higher efficiency and smaller data volume than text-based formats (such as XML and JSON). The data structure generated by the PB protocol can be converted between different programming languages ​​and different platforms, making data exchange and communication more flexible and convenient. The PB protocol supports adding new fields to existing message types without destroying compatibility with old versions of data, making the evolution and upgrade of data structures easier. The PB protocol uses a simple IDL (Interface Definition Language) to describe the data structure, and can generate the corresponding data structure class through a specific compiler, so that developers do not need to manually write cumbersome serialization and deserialization code. The PB protocol uses a binary format for data serialization, so Protocol Buffers has high efficiency and performance in network transmission and storage.

[0059] Since the PB protocol of each service is customized, special deserialization processing is required to convert the input and output parameter data sequences into more intuitive input and output parameter deserialization results.

[0060] Step S150: For the input and output parameters of each stage in the old function search link, the input and output parameters of the stage are deserialized from the data sequence of the PB protocol to obtain the deserialization result of the input and output parameters of the stage.

[0061] Step S160: compare the input and output parameter deserialization results of each stage of the new function search link with the input and output parameter deserialization results of the old function search link at that stage to obtain the difference results of the new and old function parameters at that stage.

[0062] It can be understood that the input and output parameter deserialization results are intuitive results. Therefore, the input and output parameter deserialization results of each stage of the new function search link can be directly compared with the input and output parameter deserialization results of the old function search link at that stage to obtain the difference between the input and output parameters of the new and old functions in each stage to ensure whether the calling status of the entire search link meets expectations.

[0063] The method for comparing parameters of commodities based on search links provided in this embodiment responds to a link comparison request of a target commodity based on a new function search link, calls the ID of an old function search link to be compared with the new function search link, determines the input and output parameters of the target commodity at each stage in the new function search link according to the ID of the new function search link, determines the input and output parameters of the target commodity at each stage in the old function search link according to the ID of the old function search link, deserializes the input and output parameters of each stage in the new function search link from a data sequence of the Protocol Buffers protocol to obtain a deserialization result of the input and output parameters of the stage, deserializes the input and output parameters of each stage in the old function search link from a data sequence of the Protocol Buffers protocol to obtain a deserialization result of the input and output parameters of the stage, compares the deserialization result of the input and output parameters of each stage of the new function search link with the deserialization result of the input and output parameters of the stage of the old function search link, and obtains a difference result of the new and old function parameters of the stage. It can be seen that the input and output parameters of each stage in the search link can be deserialized from the data sequence of the Protocol Buffers protocol and converted into more intuitive input and output parameter deserialization results, making it more convenient and easier to troubleshoot or compare problems with the new functions of the search link.

[0064] Considering that when analyzing the differences in input and output parameters between the new and old function search links, it is possible to analyze not only a single stage, but also the modules composed of upstream and downstream stages can be analyzed together to more efficiently and intuitively analyze the differences between the new and old function search links. Based on this, combined with Figure 2 As shown, the parameter comparison method for commodities based on search links provided in this application may also include the following process:

[0065] Step S210: Determine the input and output parameters of the target module in the new function search link and the input and output parameters of the target module in the old function search link of the target product.

[0066] Among them, the target module may include multiple stages with upstream and downstream relationships.

[0067] Step S220: For each input and output parameter of the target module in the new function search link, deserialize the input and output parameter from the data sequence of the PB protocol to obtain a deserialization result of the input and output parameter.

[0068] Step S230: for each input and output parameter of the target module in the old function search link, deserialize the input and output parameter from the data sequence of the PB protocol to obtain a deserialization result of the input and output parameter.

[0069] Step S240: compare the deserialization results of all input and output parameters of the target module of the new function search link with the deserialization results of all input and output parameters of the target module of the old function search link to obtain the difference results of the new and old function parameters of the target module.

[0070] The commodity search link-based parameter comparison method provided in this embodiment determines the input and output parameters of the target module of the target commodity in the new function search link and the input and output parameters of the target module in the old function search link, deserializes the input and output parameters of the target module in the new and old function search links from the data sequence of the Protocol Buffers protocol, obtains the deserialization results of the input and output parameters, and finally compares the deserialization results of all the input and output parameters of the target modules of the new and old function search links, so as to analyze the differences between the new and old function search links more efficiently and intuitively.

[0071] In some embodiments of the present application, the storage process of the input and output parameter deserialization results mentioned in the aforementioned embodiments is introduced. Specifically, the input and output parameter deserialization results of each stage in the old function search link and the input and output parameter deserialization results of this stage in the new function search link can be stored in Redis.
