Problems solved by technology

[0005] Multiple servers cannot use "local time" for comparison. Due to the existence of multiple clients, even the local time of one server cannot represent "absolute timing"

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] see figure 1 As shown, a method for ensuring the unique instant messaging message of multi-platform devices of the present invention comprises the following steps:

[0033] 1. A sends a message to its own login node

[0034] a. Encrypt the message content, message time (milliseconds), and random number through SHA256 (a hash algorithm that converts the input content into a fixed-length encryption algorithm through multiple modulo operations) to generate a u...

Abstract

The invention discloses a method for ensuring uniqueness of an instant messaging message of multi-platform equipment, and relates to the technical field of instant messaging. The method comprises thefollowing steps: S01, sending, by a receiver A, a message to a login node of the receiver A; S02, sending the message sent by the receiver A to a server; S03, querying online states of the receiver Aand other receivers in a database of the server; S04, issuing, by the server, the message to a received node; and S05, sending, by the node, a message to the client. According to the method, the problem of losing a message loss or sending messages twice during network switching is solved, the problem of disordered time sequence of multi-platform messages is solved, and the sending sequence of allmessage fingerprints is kept by introducing the object of the unique time queue of a central server, the unique time queue of the central server is received every time the message is received, and thecontent of the instant messaging message is displayed with referrence to the sequence of the unique time queue of the central server when the client needs to display the message.

Description

technical field [0001] The invention belongs to the technical field of instant messaging, and in particular relates to a method for ensuring unique instant messaging messages of multi-platform devices. Background technique [0002] As far as we know, most of the similar products use MD5 encryption method or 3DES encryption to ensure the uniqueness of the message. Compared with the content of the message, the same value after encryption means the same message. Of course, time and other factors must be added to ensure completeness. only. The disadvantage is that there may be omissions in multi-platform synchronization, and packet loss may occur after the network is disconnected and resumed. [0003] The disadvantage of existing similar products is that when we use the applet and computer desktop for instant messaging, we find packet loss, especially when switching networks, sometimes the same message is sent twice, resulting in an error display. Sometimes there is also a pro...
