Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2024/070614, filed on Jan. 4, 2024, which claims priority to Chinese Patent Application No. 202310815614.4, filed on Jul. 4, 2023. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD This application relates to the computer field, and in particular, to a file query method and apparatus, a computer device, and a communication system. BACKGROUND Currently, a client may mount a shared file of a server based on a network file system, and remotely access the shared file of the server through a network. For example, the client queries an attribute of a file (for example, a location and a size of the file) in the server. Generally, the client first obtains a file list from the server, and then queries attributes of files in the file list. A larger quantity of files indicates a larger quantity of query requests that need to be sent by the client, resulting in low file query efficiency and high network bandwidth overheads. SUMMARY This application provides a file query method and apparatus, a computer device, and a communication system, to resolve problems of low file query efficiency and high network bandwidth overheads. According to a first aspect, this application provides a file query method. The method includes: obtaining a file attribute of a target directory by sending a file query request that indicates to query the file attribute of the target directory, where the file attribute of the target directory indicates a file organization structure attribute of the target directory. A file organization structure may include a plurality of levels of directories, for example, a subdirectory, a first-level subdirectory, and a second-level subdirectory. A directory at each level may include a plurality of files or folders. The file attribute of the target directory may include file attributes of a plurality of files in the target directory. Compared with a case in which a client needs to send a file query request for each file, according to the file query method provided in this application, the client sends a file query request once, where the request indicates to query the file attributes of the plurality of files in the target directory, and receives attribute results of the plurality of files in the target directory, to improve file query efficiency. The query request and the attribute results are transmitted only once in a network, to reduce network bandwidth overheads. In addition, compared with a case in which the client caches a file attribute of a file, and collects statistics on file attributes of a plurality of files, according to the file query method provided in this application, the client may receive a statistics collection result of the file attributes of the plurality of files without caching the file attributes of the files and collecting statistics on and summarizing the file attributes of the files, to reduce consumption of memory resources and computing resources. According to a second aspect, this application provides a file query method. The method includes: receiving a file query request that indicates to query a file attribute of a target directory, where the file attribute of the target directory indicates a file organization structure attribute of the target directory; obtaining a file attribute of the target directory based on the received file query request; and sending the obtained file attribute of the target directory. After receiving the file query request sent by a client, a server may collectively summarize attributes such as a size of the target directory, occupied space, a total quantity of included files, and a total quantity of included folders. Optionally, the server queries attributes such as sizes and occupied space of folders included in the target directory, or attributes such as sizes and occupied space of files included in the target directory. Optionally, the server collectively summarizes attributes such as a quantity, sizes, and occupied space of folders included in the target directory, or attributes such as a quantity, sizes, and occupied space of files included in the target directory. Instead of performing a file attribute query operation on each file in the target directory, the client sends a file query request once to control the server to perform file attribute query operations on a plurality of files, to improve file query efficiency. In a possible implementation, the file query request includes an attribute parameter of at least one of a directory, a file, or a folder. In another possible implementation, an attribute parameter includes at least one of a size, occupied space, a quantity, or a file type. The file query request may meet different query granularities. The file query request includes different query granularities, and attribute parameters of query granularities at
