First, before the embodiments of the present application are described, the relevant contents of the present application about the application background will be described.
FastDFS file reception mechanism:
the FastDFS file server consists of a Storage server and a Tracker server; the Storage server is responsible for storing the uploaded files (Storage) by directly utilizing the file system of the OS, and the Tracker server is mainly responsible for load balancing and allocating Storage nodes of the Storage server to callers (such as clients of FastDFS).
(1) And a connection establishment stage: the client side of the FastDFS firstly establishes remote connection with Tracker server service and returns an available 'Storage server' service connection to the FastDFS client side; the client of the FastDFS then establishes a long remote connection with the "Storage server" service.
(2) File uploading and receiving stage: the client side of the FastDFS instructs the Storage server to create a blank 0-byte basic file in a disk of a file server through remote long connection, and returns 'fileID' of the blank file to the client side of the FastDFS, then the client side of the FastDFS sends an uploaded file stream and 'fileID' to the Storage server through long connection, the Storage server finds the corresponding blank file in the disk through 'fileID' after receiving the transmitted file stream and 'fileID' and writes file stream data into the file, and after the writing is completed, the Storage server returns 'fileID' to the client side of the FastDFS again. Therefore, when the file stream needs to be uploaded next time, only the file ID and the file stream to be uploaded need to be sent to the Storage server through the client of the FastDFS, and the file can be added.
FastDFS file delivery mechanism:
a Storage server and a Tracker server of a FastDFS file server finish file uploading and storing functions, but do not support HTTP browsing, viewing and downloading functions of files, so that a Nginx server needs to be matched with the FastDFS file server, a disk folder path of the file server is mounted and configured in the Nginx server, and then the files are accessed through a url address of HTTP.
When the nginx server intercepts a file URL access address sent by the browser, a path where the file is located is intercepted from the address, and then the nginx finds the file in the disk through the path and returns the file to the browser.

102. and sending the file identification of the blank file to a client.
103. A first file and a file identification are received from the client.
The first file is a file uploaded to a file server by a client. The client side sends a first file and a file identification to the file server at the same time, namely the first file is defaulted to be a file to be uploaded to a blank file, and the first file corresponds to the file identification.
104. And acquiring the blank file from a file server according to the file identifier.
Because the file identifier is bound with the blank file, the blank file bound with the file identifier can be inquired by taking the file identifier as an index.
105. The first file is divided into a plurality of fragment data, and each fragment data is provided with a label for identifying the arrangement sequence of the fragment data corresponding to the first file.
106. And sequentially adding the plurality of fragment data into the blank file in a streaming manner, calling a thread, and recording file uploading information of the first file added into the blank file in the file uploading information table by adopting a timing mechanism until all the fragment data of the first file are added into the blank file.
In some embodiments, after the adding the plurality of sliced data to the blank file in a streaming order, the method further comprises:
creating a user file association table, wherein the user file association table is used for recording unique association information of a user and an uploaded file;
receiving a first message from the client;
and responding to the first message, and managing the user file association table.
In some embodiments, the application supports secure access restriction of network addresses (e.g., URL addresses) in a file browsing and downloading security scheme. Specifically, the method further comprises:
the network address of the second file is intercepted by the intercepting mechanism of nginx,
adding configuration information of a third-party anti-theft chain module into the nginx configuration file;
and establishing a matching relation between the configuration information and the network address of the first file, and carrying out verification operation on the security function of the third-party anti-theft chain module.

creating an access right check interface of the network address of the second file;
receiving a second message from the client, wherein the second message carries an access address of the second file;
intercepting an access address in the second message through nginx and sending the access address to an access authority verification interface;
after determining that the client has the authority to access the second file according to the authority state information, sending an access page of the second file to the client;
and after the network address of the second file is transmitted to a back-end verification authority in a parameter form, acquiring the second file and sending the second file to the client.
