Detailed Description
The principles and features of the present application are described below with examples given for the purpose of illustration only and are not intended to limit the scope of the present application.
The embodiment of the application provides a file transmission method which can be used for realizing file transmission between two non-communicated devices (or systems). For example, a device and a device B, which are not mutually communicated, transmit a file in the device a to the device B through the file transmission system provided by the embodiment of the application. The device a or the device B may be a user device, or a device formed by integrating the user device and a network device through a network, or may also be an application running on the device, where the user device includes, but is not limited to, various terminal devices such as a computer, a mobile phone, a tablet computer, an intelligent watch, a bracelet, and the network device includes, but is not limited to, a network host, a single network server, a plurality of network server sets, or a computer set based on cloud computing, where the network device is implemented, and may be used to implement a part of processing functions when setting an alarm clock. Here, the Cloud is composed of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a kind of distributed Computing, one virtual computer composed of a group of loosely coupled computer sets. The present application is not limited to a particular implementation of the device (or system).
The file transmission method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an embodiment of a file transfer method according to an embodiment of the present application. As shown in fig. 1, in some embodiments, the file transfer method includes the steps of:
step S1, in response to a file transmission request, a transmission node and a source device are linked to form a first transmission channel. And linking the transmission node and the target device to form a second transmission channel. The file transfer request is used to indicate that the target file is transferred from the source device to the target device.
The establishment of the first transmission channel and the second transmission channel may be based on FTP protocol and SFTP protocol. The link between the source device and the file transfer system is realized by a first transmission channel established between a transmission node of the file transfer system and the source device. Similarly, the link between the target device and the file transfer system is implemented by a second transfer channel established between the transfer node of the file transfer system and the target device. It will be appreciated that the file transfer system includes, in addition to the transfer node, a processor or the like, capable of completing the reception of the instruction, the transmission of the instruction, and the generation of the instruction.
In one implementation, a file transfer system may receive a user-triggered file transfer request. For example, file a is transferred from source device a to target device B. File a serves as the target file. In one example, a file transfer system generates a first connection command and a second connection command in response to a file transfer request. The first connection command is used for indicating a file transfer system to connect the source host and a transfer node of the file transfer system. The second connection command is used for indicating the file transmission system to connect the destination host and the transmission node of the file transmission system.
Step S2, the target file is transmitted from the source device to the transmission node through the first transmission channel, and then is transmitted to the target device through the second transmission channel from the transmission node.
The transmitting node does not cache the bulk data, only as part of the channel. I.e. the data simply passes through the memory and "flows" through the transmission node. The transmission node is used for completing the handover of the transmission data.
The target file is transmitted from the source device to the target device via the transmission node, and the entire transmission process is handled as one thing.
The file transmission system does not need to complete the writing operation of the target file, so that the reading and writing operation and maintenance corresponding to the reading and writing operation are not needed, the flow of file transmission can be reduced, and the resource is saved.
In some cases, the target file includes a plurality of data packets, and each data packet of the target file is sequentially transmitted to the target device through the first transmission channel and the second transmission channel.
Fig. 2 is a flow chart of an implementation form of a file transfer method according to an embodiment of the present application. Fig. 3 is an interaction diagram of an example of the file transfer method shown in fig. 2. As shown in fig. 2 and 3, in order to ensure the accuracy of file transfer, in one implementation, when step S2 is performed, the file transfer method includes the steps of:
step S21, the first data packet is transmitted to the target device through the first transmission channel and the second transmission channel.
Step S22, the content of the first data packet is written into the target device.
The target file is transmitted from the source device to the target device through the first transmission channel and the second transmission channel, so that the whole transmission process is used as a transaction, the transmission node provides the handover function of data transmission, the recorded event number is small, and the operation and maintenance of the file transmission system are simple.
Illustratively, by performing steps S21 and S22, the file transfer system obtains a packet a1 of the file a from the link with the source device a, and writes the content of a1 to the target device B via the link between the file transfer system and the target device B.
Step S23, the second data packet is transmitted to the target device through the first transmission channel and the second transmission channel.
Step S24, the content of the second data packet is written into the target device.
Illustratively, by performing step S23 and step S24, the file transfer system acquires another data packet a2 of the file a from the source device a, and writes the content of a2 to the target device B through the link between the file transfer system and the target device B. And after the first data packet is written into the target equipment, the second data packet is transmitted, so that the accuracy of file transmission is ensured.
It will be appreciated that when the number of packets of the target file is greater than two, steps S23 and S24 may be repeated until the contents of file a are written to the target device B.
And compared with the method that a plurality of data packets are simultaneously sent from the source device to the transmission node, the method comprises the steps of simultaneously sending the plurality of data packets from the transmission node to the target device. The file transmission method provided by the embodiment of the application can realize the flow transmission of a plurality of data packets and save the time of file transmission. The data packets are sequentially transmitted, so that the memory requirement of the file transmission data node is reduced, and the method is suitable for more file transmission scenes.
To ensure accuracy of file transfer, fig. 4 is an interactive schematic diagram of an example of the file transfer method shown in fig. 2. As shown in fig. 4, in some embodiments, after performing step S22, before performing step S23, the file transfer method further includes:
step S221, after executing step S22, the target device sends a write completion instruction to the file transfer system.
In step S222, the file transfer system generates a continuation instruction in response to the write completion instruction, and transmits the continuation instruction to the source device.
Step S223, the source device responds to the resume instruction and executes step S23.
That is, after one data packet is transmitted, the file transmission system needs to send a continue command to transmit the next data packet, so as to avoid transmission errors or congestion.
Fig. 5 is a flowchart of an implementation form of a file transfer method according to an embodiment of the present application. As shown in fig. 5, in some embodiments, the file transfer method further includes:
step S201, any file in the file list is acquired, and whether the file is a target file is judged.
In some embodiments, the source device includes a plurality of non-target files in addition to the target files. The target file and the plurality of non-target files are stored in the source device in the form of a file list. The file transfer system is capable of acquiring a file list in the source device and determining whether each file in the file list is a target file.
Step S202, if the file is the target file, executing the transmission step.
In one implementation, the transmitting step includes step S2. In one example, the transmitting step includes steps S21 to S24.
After executing step S202, determining whether there is any unprocessed file; if the file is the target file and is not processed, the size of the acquired file is acquired, and the transmission step is executed.
In one implementation, a determination is made as to whether the file is a target file by obtaining an unprocessed file name.
And step S3, writing the target file into the target equipment.
In one implementation, a file is written to a specified location of a target device. For example, a file is written to a specified address temporary directory of the target device.
Above, the target file has no writing operation in the transmission node, and the target file only passes through the memory of the transmission node, namely, the target file only flows through the transmission node, so that the file transmission flow is simplified, and the file transmission speed is improved. And the target file is transmitted from the source device to the target device through the first transmission channel and the second transmission channel, the target file has no write operation at the transmission node, the transmission node does not need to buffer batch data, which means that the file transmission system does not need huge storage space, and resources are saved. The target file is transmitted from the source device to the target device through the first transmission channel and the second transmission channel, so that the whole transmission process is used as a transaction, the transmission node provides the handover function of data transmission, the recorded event number is small, and the operation and maintenance of the file transmission system are simple.
Fig. 6 is a flowchart of an implementation form of a file transfer method according to an embodiment of the present application. Fig. 7 is an interaction diagram of an example of the file transfer method shown in fig. 6. As shown in fig. 6 and 7, in some embodiments, the file transfer method further includes the steps of:
step S4, a first instruction is sent to the target equipment. The first instruction is to instruct the target device to move the target file from the temporary directory to the export directory.
Illustratively, the file transfer system sends a first instruction to target device B to transfer the a-file on target device B from the temporary directory to the export directory.
Step S5, a second instruction is sent to the source equipment. The second instruction is for instructing the source device to delete or backup the target file.
By executing step S5, in the source device, the archiving process or cleaning work of the target file is completed.
The file transfer system sends a second instruction to the source device a, and deletes or backs up the a file on the source device a.
And S6, storing an acquisition log, wherein the acquisition log comprises file information and transmitted delay information.
In order to meet the requirements of auditing and operation and maintenance of a file transmission system after file transmission work. In the process of file transmission, the file transmission system collects and stores the work log to complete the recording work of the information in the processing process. Information about the data transmission process is provided, such as transmitted file information, transmitted delay information time, file transmission time consumption, etc.
And the file transmission system only needs to collect and store logs and does not need to write in target files, so that the storage space can be saved on the basis of meeting the data maintenance work.
It will be appreciated that after step S3 is performed, any one of step S4, step S5 and step S6 may be performed, or any several of step S4, step S5 and step S6 may be performed. The sequence of step S4, step S5 and step S6 is not limited in this application. In some embodiments, step S4 and step S5 may be performed simultaneously.
