It is to be understood that the above-mentioned names for the components of the electronic device are only for identification purposes, and do not limit the embodiments of the present application accordingly.
The following describes a method for generating identification information of a message provided by an embodiment of the present application in detail based on an electronic device.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a method for generating identification information of a message according to an embodiment of the present application. The method for generating the identification information of the message is specifically applied to the electronic device provided by the embodiment, so that the efficiency of message query is improved. It is understood that the identification information generation method of the message may also be applied to a server, such as a cloud server.
As shown in fig. 2, the method for generating the identification information of the message specifically includes steps S101 to S103.
S101, identifying the message type of the current message and generating a number corresponding to the current message.
For the current message, the device identifies the message type of the message, wherein the message type comprises a device side request message type, a device side reply message type, a cloud side request message type and a cloud side reply message type. That is, the device identifies which type of the device side request message type, the device side reply message type, the cloud side request message type, and the cloud side reply message type is the current message. And, the device also generates a unique number corresponding to the current message.
Optionally, the device sets the unique number corresponding to the message to be incremented by a preset value from an initial value (e.g., zero), that is, the number corresponding to the current message is a result of adding the preset value to the number corresponding to the previous message. The preset value is optionally set to 1, and those skilled in the art can understand that the preset value may also be set to other values, which is not limited herein. The device stores the unique number corresponding to the previous message in the memory, and for the current message, the device obtains the message number currently stored in the memory, and for convenience of description, the message number currently stored in the memory is referred to as a first message number hereinafter. And then, increasing the number of the first message by a preset value, generating a corresponding second message number, and determining the second message number as a unique number corresponding to the current message. And replacing the first message number stored in the device memory with the second message number, so as to generate a third message number corresponding to the next message according to the stored second message number.
In some embodiments, when the current message is a reply message, that is, the message type of the current message is the device-side reply message type or the cloud-side reply message type, the request message corresponding to the reply message, that is, the number of the cloud-side request message or the device-side request message is obtained, and the number of the cloud-side request message or the device-side request message corresponding to the current message is determined as the number corresponding to the current message, so that the numbers of each pair of request messages and reply messages are consistent.
S102, determining an identifier corresponding to the message type of the current message according to the corresponding relation between the preset message type and the identifier.
For example, a correspondence between a message type and an identifier is preset, for example, an identifier DM corresponding to a device request message type, an identifier DR corresponding to a device reply message type, an identifier CM corresponding to a cloud request message type, and an identifier CR corresponding to a cloud reply message type, where D represents a device, C represents a cloud, M represents a request message, and R represents a reply message reply. The equipment determines the identifier corresponding to the message type of the current message according to the message type of the current message and the preset corresponding relation between the message type and the identifier.
S103, generating identification information corresponding to the current message according to the identifier and the number and a preset identification information format.
For example, an identification information format corresponding to the identification information of the message is also preset, for example, the identification information format is set as: character prefix + long integer positive suffix. And after the equipment generates a unique number corresponding to the current message, wherein the number is a long integer positive value and determines an identifier corresponding to the message type of the current message, the equipment generates identification information corresponding to the current message according to the identifier and the number and a preset identification information format. Optionally, the device adds the identifier prefix to the number by using the identifier as the prefix of the identification information, and generates the identification information corresponding to the current message. For example, DM12345678, CR12345678, CM98765432, DR98765432, and so forth.
Because the unique identification information corresponding to the message is generated, the message type can be obtained and the identification information corresponding to the request message and the identification information corresponding to the reply message can be associated according to the identification information of the message, so that the query efficiency can be greatly improved when the message is queried, for example, when the message is queried in a log.
Optionally, in some embodiments, after the device is turned on, the data stored in the flash memory of the device is read, and whether the stored data includes a reference number used to generate the unique number corresponding to the message is identified, that is, whether the reference number is stored in the flash memory of the device is determined. If the reference number is stored in the device flash memory, the reference number is determined as the first message number, and if the reference number is not stored in the device flash memory, the number zero is determined as the first message number. And adding the preset step value to the first message number, storing the first message number in the flash memory of the device as an updated reference number, and storing the first message number in the memory of the device. The preset step value may be optionally set to 20, and it should be noted that the preset step value may be flexibly set according to an actual situation, which is not limited herein.
And then, when the equipment generates the number corresponding to the current message, the equipment increments the first message number by a preset value according to the first message number stored in the memory to obtain a second message number, and the second message number is determined as the number corresponding to the current message.
Optionally, in an embodiment, after the device increments the first message number by a preset value to obtain a second message number, the device compares the second message number with a reference number currently stored in the device flash memory, and if the second message number is smaller than the reference number currently stored in the device flash memory, determines the second message number as a number corresponding to the current message. And if the second message number reaches the reference number currently stored in the device flash memory, determining the reference number currently stored in the device flash memory, namely the second message number, as the number corresponding to the current message, adding a preset step value to the reference number currently stored in the device flash memory, and replacing the reference number currently stored to update the reference number currently stored in the device flash memory. Therefore, the unique number of the current message can be generated according to the reference number currently stored in the flash memory of the device after the device is started every time, and meanwhile, when the number of the current message reaches the reference number currently stored in the flash memory of the device, the reference number currently stored in the flash memory of the device is updated by adding the preset step value to the reference number, the reference number currently stored in the flash memory of the device is not required to be updated every time a message number is generated, and the frequent updating operation of the reference number in the flash memory of the device is avoided. Meanwhile, the reference number is stored in the flash memory of the device, and data loss possibly caused by restarting and powering off of the device is avoided.
For example, as shown in fig. 3, the operation steps of the device generating the number corresponding to the message are as follows:
(1) after the equipment is started, reading the flash memory of the equipment, and judging whether the reference number is stored in the flash memory;
(2) if yes, the reference number is used as the number initial value StartID; if not, taking the numerical value 0 as the starting value StartID of the number;
(3) adding a preset step value (such as 20) to the number initial value StartID to obtain an updated reference number EndID;
(4) the number initial value StartID is stored in the memory, and the updated reference number EndID is stored in the flash memory, so that data loss is avoided;
(5) self-increment operation is carried out on the number initial value StartID in the memory, and the number initial value StartID is updated;
(6) judging whether the updated number initial value StartID reaches the updated reference number EndID stored in the flash memory;
(7) if not, the updated number initial value StartID is used as the number of the current message; if yes, the updated reference number EndID stored in the flash memory is used as the number of the current message, and the next cycle is started by returning to the step (3).
In the embodiment, the message type of the current message is identified, the number corresponding to the current message is generated, the identifier corresponding to the message type of the current message is determined according to the preset corresponding relationship between the message type and the identifier, and the identification information corresponding to the current message is generated according to the identifier and the generated number and the preset identification information format.
