Detailed Description
The metadata acquisition method solves the technical problem of low metadata acquisition efficiency in the prior art.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
a metadata collection method, the method comprising: configuring a target acquisition task for a target client; determining a target data source to be acquired according to the target acquisition task; configuring a target acquisition plug-in for a target client, wherein the target acquisition plug-in at least comprises a preset data structure, a preset connection protocol, a preset acquisition tool and a preset acquisition rule; based on the acquisition executor, the target client adopts a target acquisition plug-in to acquire first metadata in a target data source to be acquired.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The application provides a metadata acquisition method as shown in fig. 1, which comprises the following steps of S11-S14:
step S11, configuring a target acquisition task for a target client.
And step S12, determining a target data source to be acquired according to the target acquisition task.
Step S13, configuring a target acquisition plug-in for the target client, wherein the target acquisition plug-in at least comprises a preset data structure, a preset connection protocol, a preset acquisition tool and a preset acquisition rule.
Step S14, based on the acquisition executor, the target client adopts the target acquisition plug-in to acquire first metadata in the target data source to be acquired.
With respect to step S11, a target acquisition task is configured for the target client.
For the target client, when metadata acquisition is required to be performed through the target client, a target acquisition task can be configured for the target client, and the target client can be a mobile terminal, such as a mobile phone, a computer, an intelligent wearable device and the like.
Before the target client is configured with the target acquisition task, in order to ensure the acquisition safety, before the target client is configured with the target acquisition task, the method further comprises the following steps: the target client sends a login request to the target server; the target server receives the login request and verifies the login request to generate a verification result, and the target server returns the verification result to the target client; and the target client determines whether a target acquisition task can be configured for the target client through the front end according to the received verification result.
The target server receives the login request and verifies the login request, the target server verifies the login request according to the user identity credentials, when the login request is legal, the verification result is verification passing, and when the login request is illegal, the verification result is verification failing. The target server returns the verification result, i.e. "verification passed" or "verification failed", to the target client. When the verification result is 'verification passing', the user name and the password sent by the target client can be matched with the user name and the password stored in the target server, and the target client can interact with the target server; when the verification result is "verification failed", it means that the user name and the password sent by the target client cannot be matched with the user name and the password stored in the target server, and the target client cannot interact with the target server.
With respect to step S12, a target data source to be acquired is determined according to the target acquisition task.
The determination of the target data source to be acquired may be based on the target acquisition task, and specifically may include:
constructing a definition interface collection library, wherein the definition interface collection library comprises a plurality of preset definition interfaces; constructing a data source library to be acquired; determining a target definition interface from a definition interface collection library according to the target acquisition task; and determining a target data source to be acquired corresponding to the target definition interface from the data source library to be acquired according to the target acquisition task.
A definition interface library may be constructed, where the definition interface library includes a plurality of preset definition interfaces, and each definition interface includes a method of attribute information to be collected. The definition interface may define a variety of general methods for obtaining metadata and processing metadata. It will be appreciated that collection efficiency may be improved by building a library of defined interfaces.
The data source library to be acquired can also be constructed, and the data source library to be acquired comprises a plurality of data sources to be acquired. It can be appreciated that constructing a database to be acquired can also improve the acquisition efficiency.
The task of target acquisition can be realized, the target definition interface is determined from the definition interface collection library, and the target data source to be acquired corresponding to the target definition interface is determined from the data source to be acquired, and it can be understood that the target definition interface corresponds to the target data source to be acquired one by one.
Furthermore, the dynamic expansion of the database to be acquired can be performed; and updating the definition interface collection library according to the dynamic expansion result of the data source library to be acquired.
The type of the dynamic expansion metadata can be realized by using mechanisms such as dynamic expansion and reflection of a virtual machine in Java so as to achieve the purpose of updating a data source library to be acquired. The method has the advantage that new metadata can be quickly adapted at low cost without restarting or relying on the outside.
Regarding step S13, a target acquisition plug-in is configured for the target client, where the target acquisition plug-in at least includes a preset data structure, a preset connection protocol, a preset acquisition tool, and a preset acquisition rule.
The target acquisition plug-in is used for providing acquisition of metadata of different types for a target client, in other words, the purpose of the application is not acquisition of metadata of a single type. Therefore, the above objective can be achieved by the preset data structure, the preset connection protocol, the preset collection tool and the preset collection rule in the target collection plug-in.
With respect to step S14, based on the acquisition executor, the target client acquires the first metadata in the target data source to be acquired using the target acquisition plug-in.
And the target client adopts a target acquisition plug-in to acquire first metadata from a target data source to be acquired.
Furthermore, in the process of collecting the first metadata, a time stamp can be added to the first metadata; after the target client collects the first metadata, judging the time interval between the time stamp in the first metadata and the current moment; and determining the network transmission state between the target client and the data source library to be acquired according to the preset response time and the time interval.
The first metadata and the timestamp may be combined in the form of:
first metadata # timestamp
Such as: 1789# 1454634164, 1789 before the # symbol is the first metadata, 14546354164 after the # symbol is the timestamp.
Determining a time interval according to the added time stamp 14546354164 and the time when the target client receives the time stamp 14546354164, determining the transmission state of the network corresponding to the target client and the data source library to be acquired according to the time interval and the preset response time, and if the time interval is smaller than the preset response time, indicating that the transmission state of the network corresponding to the target client and the data source library to be acquired is normal; if the time interval is greater than the preset response time, the abnormal transmission state of the network corresponding to the target client and the data source library to be collected is indicated, and the relevant responsible person can check the network transmission state of the network corresponding to the target client and the data source library to be collected.
After collecting the first metadata, further comprising: constructing a metadata base, wherein the metadata base comprises a plurality of metadata; inputting the collected first metadata into a metadata base; based on a preset analysis model, the first metadata is analyzed, and the blood-edge relationship between the first metadata and each metadata in the metadata base is determined, and in particular, reference may be made to fig. 2.
