When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart of a data processing method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes:
s101, at least one data transmission request sent by a server is received, and the data transmission request comprises identification information of USB equipment to which the data transmission request is to be sent.
In this embodiment, before receiving at least one data transmission request sent by the server, the method further includes:
receiving an admission USB equipment list sent by a server, wherein the admission USB equipment list comprises identification information of at least one USB equipment which can be connected to the server; when the target USB equipment is determined to be inserted, acquiring identification information of the target USB equipment, wherein the target USB equipment is any one USB equipment; when the identification information of the target USB equipment exists in the admittance USB equipment list, an indication message inserted by the target USB equipment is sent to a server, and the indication message comprises the identification information of the target USB equipment.
Further, after the server sends an indication message inserted by the target USB device, receiving a request descriptor command sent by the server, and sending the request descriptor command to the target USB device; receiving a device descriptor returned by the target USB device according to the request descriptor command; receiving a configuration request command sent by a server, and sending the configuration request command to the target USB equipment; receiving configuration information returned by the target USB equipment according to the request configuration command; and sending the configuration information and the device descriptor to a server so that the server distributes USB device drivers for the target USB device.
This is explained below with reference to fig. 2. Fig. 2 is a schematic diagram of USB port redirection provided in an embodiment of the present disclosure. In this embodiment, the terminal device is a terminal device that can be plugged into a USB device, for example, a PC, a desktop, or the like, and serves as a client. As shown in fig. 2, the server sets a virtual USB bus driver in the virtual machine allocated to the terminal device, and sets a virtual USB driver in the terminal device, so as to implement zooming of the USB bus driver. The data of the USB equipment inserted into the terminal equipment is transmitted to the virtual machine USB driver through the USB bus of the terminal equipment, and the virtual USB driver is responsible for bidirectional data transmission between the USB bus driver of the terminal equipment and the USB client, so that all data of the USB equipment is transmitted really. The USB device driver is installed and operated in the virtual machine and interacts with the virtual machine USB bus driver, so that the USB device driver in the virtual machine does not sense that the controlled USB device is actually on the terminal device, and the application program does not sense the difference. The USB port redirection is irrelevant to specific USB equipment and application, and the USB port can be directly redirected to a virtual machine which is distributed by a server for the terminal equipment, so that the terminal equipment can transmit the data of the USB equipment to the virtual machine.
Illustratively, a virtual machine allocated by the server for the terminal device sends an allowed USB device list to the terminal device, where the allowed USB device list includes identification information of at least one USB device that can be connected to the server, i.e., the virtual machine; after receiving the access USB equipment list, the terminal equipment acquires the identification information of the target USB equipment when the target USB equipment is determined to be inserted, wherein the target USB equipment is any one USB equipment;
and when determining that the identification information of the target USB equipment exists in the access USB equipment list, the terminal equipment sends an indication message inserted by the target USB equipment to the virtual machine, wherein the indication message comprises the identification information of the target USB equipment.
Further, after the terminal device sends an indication message inserted by the target USB device to the virtual machine, the virtual machine requests a descriptor command from the terminal device according to the indication message, and after receiving the descriptor command, the terminal device sends the descriptor command to the target USB device; and the target USB equipment sends the equipment descriptor to the virtual machine according to the equipment descriptor returned by the request descriptor command to the terminal equipment. Exemplarily, after the terminal device sends the indication message inserted by the target USB device to the virtual machine, the virtual machine further sends a configuration request command to the terminal device, and the terminal device receives the configuration request command sent by the virtual machine and sends the configuration request command to the target USB device; the target USB equipment returns configuration information to the terminal equipment according to the request configuration command; the terminal device sends the configuration information to the virtual machine, the virtual machine acquires information such as manufacturer, product description and model of the target USB device according to the configuration information, and then the virtual machine allocates USB device drive for the target USB device according to the information such as manufacturer, product description and model of the target USB device and the device descriptor of the USB device. The process of allocating the USB device driver to the other USB device by the virtual machine is similar to that of the target USB device, and details are not repeated here.
For example, after the virtual machine allocates a USB device driver to each USB device of at least one USB device that can be connected to the virtual machine and is inserted into the terminal device, the virtual machine may send a data transmission request of each USB device to the terminal device through the USB device driver, where the data transmission request includes identification information of the USB device, that is, the terminal device receives at least one data transmission request sent by the virtual machine that is allocated to the terminal device through the USB bus driver by the server, and the at least one data transmission request is a data transmission request sent by the virtual machine to the terminal device through the USB device driver by the virtual machine.
S102, grouping the at least one data transmission request according to the identification information to obtain at least one data transmission request queue, wherein each data transmission request queue comprises at least one data transmission request.
In this embodiment, at least one data transmission request with consistent identification information is grouped into one group.
For example, the identification information in the data transmission request is at least one data transmission request of the usb disk and is grouped into one group, that is, all data transmission requests of the usb disk are in queue 1, and the identification information in the data transmission request is all data transmission requests of the camera and is grouped into 1 group and is in queue 2. It should be noted that, for example, as shown in fig. 2, all data transmission requests of the USB disk are transmitted from the USB device driver of the USB disk to the USB virtual bus driver, then transmitted from the USB virtual bus driver to the USB server, then transmitted from the USB server to the USB client of the terminal device through the protocol channel, then transmitted from the USB client to the virtual USB driver, then transmitted from the virtual USB driver to the USB bus driver of the terminal device, and then transmitted to the USB bus of the terminal device, and then transmitted from the USB bus of the terminal device to the USB disk. All data transmission request processes of the camera are similar to those of the usb disk, and this embodiment is not described herein again.
S103, alternately sending the data transmission request in the at least one data transmission request queue to the USB equipment corresponding to the data transmission request according to a preset mode.
Exemplarily, the sending of the data transmission request in the at least one data transmission request queue to the USB device corresponding to the data transmission request alternately according to a preset manner by the identification information of the USB device, including the priority of the USB device, includes:
and alternately sending the data transmission requests in the at least one data transmission request queue to the USB equipment corresponding to the data transmission requests according to the priority.
For example, the priority of the camera is 1 level, the priority of the usb disk is 2 level, and the priority of the camera is higher than that of the usb disk, in this embodiment, the data transmission requests in the queue 2 in the preset number may be sent to the camera in sequence, and then the data transmission requests in the queue 1 in the preset number may be sent to the usb disk in sequence, so that the data transmission requests in the queue 1 and the data transmission requests in the queue 2 are sent alternately. The data transmission requests in the queue 2 can be sent to the camera in sequence within a preset time length, and then the data transmission requests in the queue 1 can be sent to the USB flash disk in sequence within the preset time length, so that the data transmission requests in the queue 1 and the data transmission requests in the queue 2 can be sent alternately. Therefore, the data transmission requests in each queue are processed alternately according to the priority, the problem that the user feels that the identification time of the camera is long due to the fact that the USB flash disk is inserted into the USB flash disk and the data transmission requests of the USB flash disk are processed all the time is solved, and user experience is improved.
It should be noted here that after sending a data transmission request, the terminal device may send the next data transmission request without waiting for the data returned by the USB device according to the data transmission request. And when receiving the data returned by the USB equipment, sending the data to the virtual machine. For example, as shown in fig. 2, data returned by the USB disk according to the data transmission request is transmitted to the USB bus driver via the USB bus of the terminal device, then transmitted to the USB client by the USB bus driver, then transmitted to the USB server of the virtual machine by the USB client, then transmitted to the USB virtual bus driver by the USB server, and finally transmitted to the USB device driver of the USB disk by the USB virtual bus driver. The transmission process of the data returned by the camera according to the data transmission request is similar to that of the usb flash disk, and details are not described here in this embodiment.
The data processing method provided by the embodiment of the disclosure can receive at least one data transmission request sent by a server, wherein the data transmission request comprises identification information of a USB device to which the data transmission request is to be sent; grouping the at least one data transmission request according to the identification information to obtain at least one data transmission request queue, wherein each data transmission request queue comprises at least one data transmission request; the data transmission requests in the at least one data transmission request queue are alternately sent to the USB equipment corresponding to the data transmission requests according to a preset mode, so that the problem that in the prior art, when a plurality of USB equipment are redirected simultaneously, the data transmission requests of the plurality of USB equipment sequentially arrive in the data transmission request queue, and then are sequentially processed to cause poor user experience can be solved, and the user experience is improved.
