Fig. 1 is a schematic flow diagram of a data transmission method of a workgroup according to an embodiment of the present invention, and as shown in fig. 1, an execution subject of the method is a terminal, and the method includes S101 and S102, specifically:
s101, subscribing at least one theme in the IPFS network, wherein each theme is used for representing a unique corresponding workgroup.
The IPFS (InterPlanetary File System) network is a network transport protocol aimed at creating persistent and distributed storage and sharing files. It is a content addressable hypermedia distribution protocol. The nodes in the IPFS network will constitute a distributed file system. IPFS solves the problems of data transmission and positioning by using a distributed hash table, and the equal relation between hosts is ensured by the characteristic of P2P. The message transmission of each host is completed by using a message publishing and subscribing mode, the publishing and subscribing mode defines a one-to-many relationship, a plurality of observer objects monitor a certain subject object at the same time, all the observed objects are informed when the state of the subject object is changed, the message of the subject is transmitted in an IPFS network, and each workgroup is a different subject. The embodiment of the invention does not limit the number of the topics subscribed by the terminal.
S102, issuing a first message in the IPFS network, wherein the first message records the name of a first theme and the addressing address of a file, so that other terminals subscribing to the first theme can monitor the first message.
It should be noted that, after a user subscribes to a topic, a message of the corresponding topic may be published, where the message of the embodiment of the present invention includes a first message, and a name of the first topic and an addressing address of a file are recorded in the first message, so that other terminals subscribing to the first topic can monitor the first message, and after monitoring the first message, the other terminals can find the corresponding file according to the addressing address of the file recorded in the first message. Because the data in the IPFS network cannot be deleted, and the addressing address corresponding to the data can also be changed after the data is changed, the previous data can be found through the original hash value, the data cannot be lost even if the safety encryption specified by the protocol of the message layer is cracked, and the safety is well guaranteed.
The data transmission method of the workgroup of the embodiment of the invention utilizes the message subscription mode of the IPFS network to represent the workgroup by the theme, so that the data transmission can be realized by a terminal subscribing the same theme, and because the data in the IPFS network can not be deleted, and the addressing address corresponding to the data can also be changed after the data is changed, the previous data can be found through the original hash value, even if the safety encryption specified by the protocol of the message layer is cracked, the data can not be lost, and the safety is ensured well.

That is, the unique identifier of the other terminal is also recorded in the response message sent by the other terminal.
On the basis of the above embodiment, as an optional embodiment, after the terminal receives the response message, the unique identifier recorded in all the received response messages is locally recorded. By recording the unique identification of other terminals, the terminal can know how many terminals exist in the same theme at the current moment.
On the basis of the foregoing embodiment, as an optional embodiment, the issuing of the second message in the IPFS network specifically includes:
and if the addressing address of the required file is retrieved from the local file list, obtaining the file according to the addressing address of the required file.
On the basis of the foregoing embodiment, as an optional embodiment, the issuing of the second message in the IPFS network specifically includes:
and if the addressing address of the required file is not retrieved in the local file list or the time from the current moment to the last time of updating the unique identifiers of all other terminals of the local record is greater than a preset threshold value, issuing a second message in the IPFS network.
When the file required by the terminal does not exist in a local file list, judging and updating the unique identification of all other terminals recorded locally; and if the unique identifiers of all other terminals recorded locally are not updated, searching the file to be acquired according to the locally stored file list.
On the basis of the foregoing embodiments, as an optional embodiment, before issuing the first message in the IPFS network, the method further includes: uploading a file to the IPFS network, and receiving an addressing address of the file returned by the server.
It should be noted that, in the embodiment of the present invention, after the terminal uploads the file to the IPFS network, the server returns the address of the file in the IPFS network to the terminal, so that the terminal can share the address of the file uploaded by the terminal to other terminals on the same topic after knowing the address of the file uploaded by the terminal.
