Detailed Description
The terminology used in the embodiments of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in this disclosure and the claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.
It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. Depending on the context, moreover, the word "if" as used may be interpreted as "at … …" or "when … …" or "in response to a determination".
The managed devices deployed inside the enterprise can directly access the management devices inside the enterprise, in which case the device management pages can be directly accessed by http protocol requests.
The management device deployed in the public network cannot directly access the management device inside the enterprise, and the device actively initiates a request to establish a WebSocket connection with the management device. After the WebSocket connection is established, the receiving and managing device can send a request message to the device through the WebSocket connection to acquire Web page data of the managing device.
The terminal accesses the hosting device and sends a request URL for logging in the management device at the hosting device. For example, a GET request: http:// nanotube device IP/device/web/frame/login
The receiving device receives the terminal login request, encapsulates the request headers, the request body and the URL (converted into request URL of the management device: http://127.0.0.1/web/frame/login. html) into a specific format WebSocket message, and sends the message to the management device through the WebSocket.
And the management equipment restores the request after receiving the message, and the proxy terminal accesses the Web service of the management equipment.
The management equipment acquires the response heads and the response body of the request, packages the response heads and the response body into a WebSocket message with a specific format and responds the WebSocket message to the admission equipment.
And the receiving device receives the WebSocket message, processes and restores the WebSocket message into a response of the URL request and sends the response to the terminal.
Since WebSocket can be inefficient in directly transferring large data, special processing is required for files larger than 1 MB. The large-size file is transmitted in a fragmentation mode through a WebSocket protocol, so that the large-size file can occupy connection resources when being transmitted, the response time of other request messages is prolonged, the response time and the throughput of the nanotube device can be further reduced, and the efficiency is very low.
In view of the above, the present disclosure provides a file transmission method, a file transmission device, an electronic device, and a machine-readable storage medium to solve the problem of low transmission efficiency of large files.
Specifically, the technical scheme is as follows.
In one embodiment, the present disclosure provides a file transfer method applied to a nanotube device, the method including: receiving a file uploading request sent by a terminal, and transferring a file to be uploaded in the file uploading request to a file server; replacing the file to be uploaded included in the file uploading request according to the acquired downloading link of the file to be uploaded fed back by the file server; and forwarding the rewritten file uploading request to the management equipment so that the management equipment downloads the file to be uploaded from the file server according to the downloading link included in the file uploading request.
Specifically, as shown in fig. 1, the method comprises the following steps:
and step S11, receiving a file uploading request sent by the terminal, and transferring the file to be uploaded included in the file uploading request to the file server.
And step S12, replacing the file to be uploaded included in the file uploading request according to the acquired downloading link of the file to be uploaded fed back by the file server.
Step S13, the rewritten file upload request is forwarded to the management device.
And the management equipment downloads the file to be uploaded from the file server according to the download link included in the file uploading request.
The large file to be transmitted is transferred and stored through the file server, so that only the download link related to the large file to be transmitted needs to be transmitted through the WebSocket protocol, the response time of other request messages is not increased, the response time and the throughput of the nanotube management equipment are not reduced, and the efficiency is high.
In one embodiment, the receiving a file upload request sent by a terminal, and transferring a file to be uploaded included in the file upload request to a file server includes: receiving a file uploading request sent by a terminal, transferring a file to be uploaded, of which the file size is larger than a threshold value, in the file uploading request to a file server, and executing subsequent steps.
In an embodiment, the replacing the file to be uploaded included in the file upload request according to the obtained download link of the file to be uploaded fed back by the file server includes: and setting a flag bit, wherein the flag bit is used for indicating that the associated file uploading request comprises a downloading link fed back by the file server.
In an embodiment, the present disclosure also provides a file transmission method applied to a nanotube device, where the method includes: receiving a file downloading request sent by a terminal, and forwarding the file downloading request to a management device so that the management device uploads a related file to be downloaded to a file server according to the file downloading request and feeds back a related downloading link to a nano management device; downloading the associated file to be downloaded from the file server according to the download link; and forwarding the file to be downloaded to the terminal.
Specifically, as shown in fig. 2, the method comprises the following steps:
and step S21, receiving the file downloading request sent by the terminal, and forwarding the file downloading request to the management device.
The management equipment uploads the associated file to be downloaded to the file server according to the file downloading request and feeds back the associated downloading link to the nano management equipment
And step S22, downloading the associated file to be downloaded from the file server according to the download link.
And step S23, forwarding the file to be downloaded to the terminal.
The large file is stored in the file server, and only the storage download path of the file is subjected to message communication, so that the influence of large file transmission on the transmission efficiency of other messages is reduced, and the response speed and the throughput of the nanotube device are greatly increased.
The management device deployed on the public network cannot directly access the management device inside the enterprise, and the device actively initiates a request to establish a WebSocket connection with the management device. After the WebSocket connection is established, the receiving and managing device can send a request message to the device through the WebSocket connection to acquire a Web page of the managing device.
The transmission mode is selected according to the file size, for example, when the file is smaller than the threshold value of 1MB, the base64 encoding mode is used; when the file is larger than or equal to the threshold value of 1MB, the URL equivalent replacement mode is used. This threshold for file size may be set as desired depending on the context of the actual network application.
In the WebSocket message, the flag bit is russian 0, which indicates that the transmission mode of the message is a base64 encoding mode, and indicates that the data in the body field in the message is base64 encoded data.
When the file uploaded by the terminal is less than 1MB, the management equipment performs base64 coding on data in the request body of the terminal, assigns a body field in the WebSocket message, resets the flag bit, judges whether the base64 is needed to decode and restore the body according to the value of the flag bit, and then proxies the request.
When the terminal download file is less than 1MB, the receiving and managing device carries out base64 coding on the data in the request body of the terminal, assigns a body field in the WebSocket message, resets the flag bit, judges whether the base64 is needed to decode and restore the body according to the value of the flag bit, and then sends the body to the terminal.
In the WebSocket message, the flag position bit indicates that the message transmission mode is a URL equivalent replacement mode, and indicates that the data in the body field in the message is big data (more than or equal to 1M).
When the file uploaded by the terminal is more than or equal to 1MB, the data in the request body of the terminal is uploaded to the file server by the receiving device, the URL downloading link of the data is obtained, the URL link is assigned to the body field in the WebSocket message, the flag bit is set, the management device can judge whether the original file needs to be downloaded by the URL link in the body according to the value of the flag bit and restore the body data, and then the request is proxied.
Because the management equipment is in an NAT intranet environment and cannot provide external downloading URL links, large file downloading can be realized by a file server, and a field 'urlExt' is added to the request message, namely, the address of the file server is specified.
When the terminal downloads the file with the file size being more than or equal to 1MB, the management device uploads the data in the file downloading request body to the specified file server, acquires the URL downloading link, assigns the URL link to the body field in the WebSocket message, sets the flag bit, and the admission device downloads the original file body data and restores the body according to the flag bit and the URL link in the body and then sends the original file body data to the terminal.
