Detailed ways

The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the drawings in the embodiments of the present application. It is obvious that the described embodiments are a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a data acquisition method according to an embodiment of the present application. The data acquisition method is applied to terminals such as desktop computers, laptop computers, tablet computers, and personal digital assistants (PDAs).

Generally, a plurality of terminals are included in a local area network. In order to facilitate the differentiation of the terminals, the terminal that sends the data may be referred to as the transmitting terminal, and the terminal that receives the data is referred to as the receiving terminal. For example, a terminal that transmits a broadcast packet is referred to as a transmitting terminal, and a terminal that receives a broadcast packet is referred to as a receiving terminal. It can be understood that each terminal can serve as both a receiving terminal and a transmitting terminal in the entire local area network.

The specific process of the data acquisition method in this embodiment will be described below from the perspective of the transmitting terminal. As shown in FIG. 1, the data acquisition method includes steps S101 to S105.

S101. If a data acquisition instruction is detected, obtain identifier information of the data to be acquired.

For example, when the user clicks on the operation interface of the life insurance system application in the sending terminal, if the user wants to obtain a certain policy data, the user clicks the URL (Uniform Resoure Locator) address of the policy data. At this time, the transmitting terminal will detect the data acquisition instruction, and acquire the identification information of the policy data according to the data acquisition instruction. It can be understood that the policy data is the data to be acquired.

In an embodiment, the identification information of the data to be acquired may be an identifier that uniquely identifies the data to be acquired, such as a URL address and a file name, and is not specifically limited herein.

S102. Generate a broadcast data packet according to the identifier information of the to-be-obtained data.

After obtaining the identification information of the data to be acquired, the broadcast data packet is generated according to the identification information. The broadcast data packet carries the identification information of the data to be acquired.

In an embodiment, please refer to FIG. 2. FIG. 2 is a schematic diagram of a specific process of step S102 in the data acquisition method shown in FIG. Step S102 specifically includes steps S1021 to S1023.

Step S1021: Acquire an internet protocol address of all the receiving terminals in the local area network.

In an embodiment, when obtaining an Internet Protocol Address (IP address) of all the receiving terminals in the local area network, the IP address of the sending terminal is also required to be acquired. This can facilitate communication between various terminals in the LAN.

Step S1022: Filter all the Internet Protocol addresses in the local area network to obtain an online Internet protocol address.

In order to prevent the transmission of broadcast data packets from occupying too many resources on the local area network, congestion in the local area network is caused. Therefore, after obtaining the IP addresses of all receiving terminals in the local area network, all the obtained IP addresses need to be screened online to filter out the online IP address. In this way, the broadcast data packet can be more specifically transmitted to each online receiving terminal, so that the network resources in the local area network can be reasonably utilized to avoid congestion of the local area network.

In an embodiment, the online IP address may refer to an IP address that has been connected to the network. For example, if a computer in the LAN is connected to the LAN, the IP address of the computer is the online IP address.

Specifically, in an embodiment, the online IP address can be filtered out by a ping (Packet Internet Groper) command. It should be noted that the manner of filtering the online IP address is not limited to the ping command, and may be other modes, and no specific limitation is imposed herein.

Step S1023: Generate a broadcast data packet according to the identification information of the data to be acquired and the Internet protocol address of the online.

In an embodiment, after obtaining the online IP address and the IP address of the transmitting terminal, the broadcast data packet is generated according to the identification information of the data to be acquired, the online IP address, and the IP address of the transmitting terminal. Specifically, in an embodiment, information such as a broadcast message header, identification information of the data to be acquired, an online IP address, and an IP address of the transmitting terminal may be generated according to a format of the broadcast data packet.

Of course, in other embodiments, the operation of step S1022 may not be performed. That is, the generating the broadcast data packet according to the identifier information of the to-be-obtained data may include: acquiring an internet protocol address of all the receiving terminals in the local area network; and identifying information and all the information according to the to-be-obtained data. The Internet Protocol address of the receiving terminal generates a broadcast data packet. In this way, when the broadcast data packet is subsequently sent, all the receiving terminals in the local area network receive the broadcast data packet.

S103. Send the broadcast data packet to at least one receiving terminal in the local area network.

In an embodiment, as shown in FIG. 3, FIG. 3 is a schematic diagram of a scenario of a data acquisition method according to an embodiment of the present application. After the transmitting terminal generates the broadcast data packet, the broadcast data packet is sent to the at least one receiving terminal through the local area network.

In an embodiment, the sending terminal may specifically send the broadcast data packet through a UDP (User Data Protocol) protocol.

In this embodiment, after receiving the broadcast data packet, the receiving terminal in the local area network searches locally for the corresponding data to be acquired according to the identification information of the data to be acquired in the broadcast data packet. If the receiving terminal determines that the data to be acquired is stored locally, the receiving terminal generates an acknowledgement message, and feeds the acknowledgement information to the sending terminal through the local area network to notify the sending terminal that the data to be acquired is stored.

S104. Determine whether the acknowledgment information fed back by the receiving terminal is received, where the acknowledgment information is that, after receiving the broadcast data packet, the receiving terminal searches for the corresponding to-be-acquired according to the identifier information of the data to be acquired. Feedback information generated when the data is obtained.

After the transmitting terminal sends the broadcast data packet, it will continuously monitor whether it receives the confirmation information fed back by the receiving terminal.

In an embodiment, determining whether the acknowledgment information fed back by the receiving terminal is received, specifically: determining whether the acknowledgment information fed back by the receiving terminal is received within a preset time. For example, determine if a confirmation message is received within 0.5 seconds. If the acknowledgment message has not been received for more than 0.5 seconds, the other receiving terminals in the local area network have no data to be acquired, and the sending terminal can be prevented from waiting for a long time.

If the sending terminal does not receive the acknowledgement information received by the receiving terminal, the data to be acquired is not stored in other terminals in the local area network. In this case, the sending terminal may obtain the data to be acquired from the server. Specifically, as shown in FIG. 3, the transmitting terminal may send a data acquisition request to the server to acquire the to-be-obtained data from the server.

If the transmitting terminal receives the confirmation information fed back by the receiving terminal, the terminal performs step S105.

S105. If the confirmation information fed back by the receiving terminal is received, the to-be-obtained data is obtained according to the confirmation information.

In an embodiment, if the receiving terminal has complete data to be acquired, the confirmation information includes the identification information of the data to be acquired. In this case, the acquiring the data to be acquired according to the confirmation information may be: acquiring the to-be-obtained data from the receiving terminal according to the confirmation information. That is to say, the transmitting terminal can obtain complete data to be acquired from the receiving terminal.

Specifically, the confirmation information further includes an internet protocol address and a communication port number of the receiving terminal. Acquiring the to-be-obtained data from the receiving terminal according to the confirmation information, comprising: establishing a communication connection with the receiving terminal according to an internet protocol address of the receiving terminal; and receiving, by the receiving terminal, the sending terminal according to the communication port number The data to be acquired.

In an embodiment, the communication port number can be a Socket port number. The transmitting terminal can establish a TCP (Transmission Control Protocol) communication connection with the receiving terminal according to the IP address of the receiving terminal. Then, the corresponding communication port is found according to the Socket port number, and the data to be acquired is received through the communication port.

In another embodiment, please refer to FIG. 4. FIG. 4 is a schematic diagram of a specific process of step S105 in the data acquisition method shown in FIG. In this embodiment, when the receiving terminal acquires data from the server, the server may divide the data to be acquired into a plurality of data blocks for transmission. That is, the data to be acquired includes a plurality of data blocks. Due to network interruption and the like, the receiving terminal may only obtain a few data blocks, that is, only a part of the data to be acquired is stored in the receiving terminal. At this time, the confirmation information fed back by the receiving terminal will include the identification information of the stored data block in the receiving terminal and the identification information of the unstored data block.

The identifier information of the stored data block and the identifier information of the unstored data block may be identifiers configured by the server for each data block. For example, if the data to be acquired includes 4 data blocks, the server may configure identification information for each of the 4 data blocks as a, b, c, and d. The server transmits the identification information of the four data blocks to the receiving terminal, and simultaneously transmits the data block to the receiving terminal. It is assumed that after the receiving terminal receives the a data block and the b data block, the network of the receiving terminal fails, so that the receiving terminal cannot acquire the c data block and the d data block from the server. Therefore, the confirmation information fed back by the receiving terminal carries the identification information a and b of the stored data block, and the identification information c and d of the unstored data block.

When the confirmation information includes the identification information of the stored data block in the receiving terminal and the identification information of the unstored data block, the obtaining the data to be acquired according to the confirmation information may specifically include steps S1051 to S1052.

S1051: Acquire a corresponding data block from the receiving terminal according to the identifier information of the stored data block.

Specifically, the transmitting terminal establishes a communication connection with the receiving terminal according to the confirmation information, and acquires a corresponding data block from the receiving terminal according to the identification information of the stored data block. For example, the confirmation information includes an IP address of the receiving terminal, establishes a TCP communication connection with the receiving terminal according to the IP address of the receiving terminal, and then acquires a data block and b data block of the data to be acquired from the receiving terminal.

S1052: Acquire a corresponding data block from the server according to the identifier information of the unstored data block to complete acquiring the to-be-obtained data.

Specifically, as shown in FIG. 3, the transmitting terminal generates a data acquisition request according to the identification information of the data to be acquired and the identification information of the unstored data block, and sends the data acquisition request to the server to obtain the unstored data block from the server. The identification information corresponds to the data block. For example, the c data block and the d data block of the data to be acquired are obtained from the server.

In an embodiment, after the sending terminal acquires the data to be acquired, the data to be acquired is stored in the local storage. For example, the local hard drive is medium. In this way, when other terminals in the local area network need the data to be acquired, data can be acquired from the sending terminal.

In an embodiment, the open source component DiskCache.NET can be used to create a hard disk space as a cache to store data to be acquired. In order to prevent the data to be acquired from being tampered with, the data to be acquired may be encrypted by the DiskCache.NET component.

In an embodiment, after acquiring the to-be-obtained data according to the confirmation information, the method further includes: monitoring whether a network status between the receiving terminal and the receiving terminal is in a busy state; and if a network status between the receiving terminal and the receiving terminal When it is busy, it continues to acquire data from other receiving terminals in the local area network.

The busy state may be a state when the network signal strength between the transmitting terminal and the receiving terminal is lower than a threshold, that is, a network signal difference. Of course, the busy state can also be other states, and no specific restrictions are imposed here.

When the transmitting terminal detects that the network state between the receiving terminal and the receiving terminal is busy, it can continue to receive data to other receiving terminals in the local area network. For example, when a plurality of pieces of confirmation information are received in step S105, one piece of confirmation information may be selected among other confirmation information, and the data may be continuously acquired from the corresponding receiving terminal according to the confirmation information.

Of course, when it is monitored that the network state between the receiving terminal and the receiving terminal is busy, the data can also be continuously obtained from the server.

In addition, the data acquisition method in an embodiment may be embedded in various application systems in the form of a plug-in, for example, embedded in a life insurance system application in the form of a plug-in. The data acquisition method can also be embedded into the Windows service based on the service deployment technology of .NET and packaged into a Windows service. The terminal can use the data acquisition method by deploying the Windows service.

The data obtaining method in the embodiment obtains the identification information of the data to be acquired when the data acquisition instruction is detected; generates the broadcast data packet according to the identification information of the data to be acquired, and sends the broadcast data packet to at least one receiving terminal in the local area network. After receiving the confirmation information fed back by the receiving terminal, the data to be acquired is obtained according to the confirmation information. The method can reasonably utilize the resources of the server and the local area network, and obtain the data from the receiving terminal when the receiving terminal in the local area network stores the data to be acquired, so as to alleviate the access pressure caused by directly acquiring data from the server, and obtain the access pressure from the local area network. The speed of the data is relatively fast, which can improve the efficiency of data acquisition. In addition, since the access pressure of the server is greatly alleviated, the efficiency of the terminal to obtain data from the server in the local area network can be further improved.
