The best mode of the invention

In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

1, an embodiment of the present application provides a method for sending a heartbeat packet based on an intermediate server, including the following steps:

S1. Receive a heartbeat subscription request for a designated terminal sent by a consumer terminal, where the heartbeat subscription request carries heartbeat detection time interval information;

S2. Count the number of consumer terminals that send the heartbeat subscription request, and determine whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold;

S3. If the number of consumer terminals sending the heartbeat subscription request is greater than the preset heartbeat subscription number threshold, send a heartbeat packet acquisition request to the designated terminal;

S4. Receive a heartbeat packet sent by the designated terminal according to the heartbeat packet acquisition request;

S5. Send the heartbeat packet to the consumer terminal that sends the heartbeat subscription request according to the time interval specified by the heartbeat detection time interval information.

As described in step S1 above, the intermediate server receives the heartbeat subscription request for the designated terminal sent by the consumer terminal, and the heartbeat subscription request carries the heartbeat detection time interval information. In the network information transmission, the heartbeat mechanism is to send a custom structure (heartbeat packet, heartbeat information) at regular intervals to let the other party know that he is still alive to ensure the validity of the connection. The heartbeat state is divided into static (ie abnormal ) Or activity (ie normal). The heartbeat detection in this application is to use the heartbeat packet to detect whether the designated terminal is abnormal. The heartbeat packet in this embodiment may be any heartbeat packet, for example, a heartbeat packet containing information such as a timestamp, a heartbeat interval, and a service IP. The consumer terminal refers to a terminal that consumes services of a designated terminal, that is, a terminal that interacts with the designated terminal, and the consumer terminal is, for example, any terminal such as a PC terminal or a mobile phone terminal. The designated terminal refers to a terminal or a server terminal that interacts with the consumer terminal, such as a social software server, a weather information providing server, etc. The heartbeat subscription request refers to a request for obtaining a heartbeat packet of a specified terminal according to the heartbeat detection time interval information. Wherein, the consumer terminal and the designated terminal are relative terms, that is, when a terminal (or server) requires another terminal (or server) to detect the heartbeat, the certain terminal (or server) is the consumer Terminal, correspondingly, the other terminal (or server) is the designated terminal; otherwise, the certain terminal (or server) is the designated terminal, and correspondingly, the other terminal (or server) is the consumer terminal.

As described in step S2, the number of consumer terminals that send the heartbeat subscription request is counted, and it is determined whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold. The heartbeat mechanism in the prior art is to perform direct heartbeat detection between a consumer terminal and a designated terminal. This kind of heartbeat detection needs to send and receive heartbeat packets through an HTTP request each time. When the number of consumer terminals is large, the heartbeat detection The overhead will make the designated terminal unbearable. Therefore, this embodiment counts the number of consumer terminals that send the heartbeat subscription request, and determines whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold, so as to determine whether the specified terminal can tolerate If the overhead of heartbeat detection in the prior art cannot be tolerated, an intermediate server is used for transfer instead of sending heartbeat packets to different consumer terminals. If it can be tolerated, the heartbeat packet is sent and received directly through HTTP requests. can. The method for determining whether the designated terminal can tolerate the overhead of heartbeat detection in the prior art is achieved by determining whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold.

As described in step S3 above, if the number of consumer terminals sending the heartbeat subscription request is greater than the preset heartbeat subscription number threshold, a heartbeat packet acquisition request is sent to the designated terminal. As mentioned above, it can be seen that if the number of consumer terminals sending the heartbeat subscription request is greater than the preset heartbeat subscription number threshold, indicating that the specified terminal cannot tolerate the overhead of heartbeat detection in the prior art, the heartbeat packet can be transferred through the intermediate server. Accordingly, the intermediate server sends a heartbeat packet acquisition request to the designated terminal, thereby requiring the designated terminal to send a heartbeat packet.

As described in step S4 above, receiving the heartbeat packet sent by the designated terminal according to the heartbeat packet acquisition requirement. The heartbeat packet sent by the designated terminal may be sent at predetermined intervals, and the predetermined time may be set by the designated terminal, or may be set by the designated terminal according to a predetermined time set by the intermediate server, or may be set by the designated terminal. The designated terminal is set according to the heartbeat detection time interval information carried in the heartbeat subscription request. According to this, a heartbeat packet is received.

As described in step S5 above, the heartbeat packet is sent to the consumer terminal that sends the heartbeat subscription request according to the time interval specified by the heartbeat detection time interval information. Since the heartbeat subscription request sent by the consumer terminal to the specified terminal carries the heartbeat detection time interval information, that is, the consumer terminal requires the heartbeat detection time interval, so the heartbeat packet is sent according to the heartbeat detection time interval to complete the heartbeat packet send. The consumer terminal receiving the heartbeat packet can complete the heartbeat detection according to the heartbeat packet to determine the status of the designated terminal (abnormal or normal), and then determine the subsequent instructions according to the status of the designated terminal (for example, if the designated terminal is abnormal, disconnect The connection with the designated terminal, or re-verify the login account, etc.). In addition, this application adopts the time interval specified by the heartbeat detection time interval information from the consumer terminal. First, the intermediate server does not need to set the time interval, thereby reducing the procedure and improving the efficiency; and the heartbeat detection time interval information set by the consumer terminal itself is more It is adapted to the consumer terminal itself, so different consumer terminals can achieve different and most appropriate time intervals, thereby making the heartbeat detection method more flexible.

In one embodiment, before step S2 of counting the number of consumer terminals that have sent the heartbeat subscription request, and determining whether the number of consumer terminals that have sent the heartbeat subscription request is greater than a preset heartbeat subscription number threshold, the step S2 includes:

S201: Determine whether the designated terminal exists in a preset list of providing heartbeat services;

S202: If the designated terminal exists in the preset list of providing heartbeat services, determine whether the login user of the consumer terminal is a authorized user;

S203. If the logged-in user of the consumer terminal is a privileged user, trigger the counting of the number of consumer terminals sending the heartbeat subscription request, and determine whether the number of consumer terminals sending the heartbeat subscription request is greater than a preset heartbeat Steps to subscribe threshold.

As described above, it is possible to determine whether the number of consumer terminals that send the heartbeat subscription request is greater than the preset threshold for the number of heartbeat subscriptions. In this embodiment, by judging whether the designated terminal exists in the preset list of providing heartbeat services, it is judged whether it can realize heartbeat information interaction with the designated terminal, and then the consumer terminals are divided into two types, authorized and non-authorized. Allow authorized consumer terminals to subscribe to the heartbeat, thereby achieving hierarchical management and reducing the pressure on the intermediate server. Among them, the terminal that can provide heartbeat packets is pre-stored in the list of providing heartbeat services. Wherein, judging whether the logged-in user of the consumer terminal is a privileged user may be in any manner, for example, by judging whether the logged-in user of the consumer terminal exists in a preset privilege list.

In one embodiment, the authority of the authorized user is divided into multiple levels, and the step of judging whether the login user of the consumer terminal is a authorized user if the designated terminal exists in a preset list of providing heartbeat services S202, including:

S2021: If the designated terminal exists in the preset list of providing heartbeat services, obtain the login user name of the consumer terminal;

S2022. Obtain the authority level of the consumer terminal by querying the login user name of the consumer terminal in the pre-stored authority user list, where the authority user list includes the user name, the authority level, and the terminal corresponding to the authority level;

S2023: Determine whether the terminal corresponding to the authority level of the consumer terminal includes the designated terminal;

S2024. If the terminal corresponding to the authority level of the consumer terminal includes the designated terminal, determine that the login user of the consumer terminal is a authority user.

As mentioned above, it is possible to determine whether the login user of the consumer terminal is a privileged user. In this embodiment, the authority of the authority user is divided into multiple levels to further realize hierarchical management. For example, for a preset user with the highest level of authority, it is allowed to subscribe heartbeat information to all servers in the preset list of providing heartbeat services; for a low-level user, it is only allowed to subscribe to some commonly used servers in the preset list of providing heartbeat services. Subscribe to heartbeat information. The authority of the authority user is determined, and the login user name of the consumer terminal is searched in a pre-stored authority user list to obtain the authority level of the consumer terminal. The authority user list includes the user name, authority level, and authority. The terminal corresponding to the level. If the authority of the login user of the designated terminal and the consumer terminal matches (that is, the authority is sufficient), it is determined that the login user of the consumer terminal is the authority user.

In one embodiment, after the step S2 of counting the number of consumer terminals sending the heartbeat subscription request and determining whether the number of consumer terminals sending the heartbeat subscription request is greater than a preset heartbeat subscription number threshold, the method includes:

S21: If the number of consumer terminals sending the heartbeat subscription request is not greater than the preset heartbeat subscription number threshold, reject the heartbeat subscription request sent by the consumer terminal;

S22. Send to the consumer terminal information suggesting to directly obtain the heartbeat packet from the designated terminal.

As described above, it is realized that the heartbeat subscription request sent by the consumer terminal is rejected. The preset threshold of the number of heartbeat subscriptions reflects the standard value of the endurance of the heartbeat overhead of the specified terminal. When the number of consumer terminals sending the heartbeat subscription request is not greater than the preset threshold of the number of heartbeat subscriptions, it indicates that the designated terminal can tolerate the overhead of heartbeat detection using the prior art, so the consumer terminal directly requests the designated terminal for a heartbeat packet That's it, without going through an intermediate server. Therefore, the heartbeat subscription request sent by the consumer terminal is rejected, and then the consumer terminal is sent to the consumer terminal suggesting that the heartbeat packet be directly obtained from the designated terminal.

In one embodiment, the step S5 of sending the heartbeat packet to the consumer terminal that sends the heartbeat subscription request according to the time interval specified by the heartbeat detection time interval information includes:

S501. Deliver the heartbeat packet to a preset message middleware;

S502: According to the time interval specified by the heartbeat detection time interval information, send the most recently received heartbeat packet in the message middleware to the consumer terminal that sent the heartbeat subscription request.

As described above, the heartbeat packet is sent to the consumer terminal that sends the heartbeat subscription request according to the time interval specified by the heartbeat detection time interval information. In this embodiment, a preset message middleware is used to send the heartbeat packet. Among them, message middleware (such as MQ message queue service (Message Queue, MQ)) is an application that can be deployed on the server to ensure message transfer between heterogeneous applications. The MQ interface is used for interconnection and communication. Care about the details of communication on the network. Therefore, the heartbeat packet will be queued in the message middleware, waiting to be sent to the consumer terminal. Since consumer terminals generally need the latest heartbeat packet, they only need the latest heartbeat packet received from the message middleware (if the designated terminal sends heartbeat packets more frequently, it will appear in one of the heartbeat detection Within the time interval specified by the time interval information, multiple heartbeat packets are received) and sent to the consumer terminal to complete the heartbeat packet sending process. Further, all heartbeat packets in the message middleware can also be sent to the consumer terminal.

S511: According to the time interval specified by the heartbeat detection time interval information, at the first time point of sending a heartbeat packet after the current time, according to a preset heartbeat abnormality judgment rule, judge whether the designated terminal is abnormal;

S512: If the designated terminal is abnormal, send the abnormal information of the designated terminal and the heartbeat packet to the consumer terminal that sends the heartbeat subscription request.

As mentioned above, the heartbeat packet is sent. The prior art generally only determines whether the heartbeat is abnormal by the terminal itself, that is, the terminal needs to receive the heartbeat packet first, and then judge whether the designated terminal is abnormal by the heartbeat packet. In this embodiment, the intermediate server first executes the process of judging whether the designated terminal is abnormal, so that whether the designated terminal is abnormal can be obtained before sending the heartbeat packet to the consumer terminal. Compared with the prior art, it is faster and saves time. Especially suitable for situations requiring high timeliness. Therefore, if the designated terminal is abnormal, the abnormal information of the designated terminal and the heartbeat packet are sent to the consumer terminal that sends the heartbeat subscription request. Further, the consumer terminal can use the heartbeat packet to further verify whether the judgment conclusion of the intermediate server is accurate.

In one embodiment, according to the time interval specified by the heartbeat detection time interval information, the designated terminal is determined according to a preset heartbeat abnormality judgment rule at the first time point of sending a heartbeat packet after the current time The step S511 of whether it is abnormal includes:

S5111, according to the time interval specified by the heartbeat detection time interval information, at the first time point of sending a heartbeat packet after the current time, determine whether the difference between the current time and the time of the last heartbeat packet reception is greater than 2×the The time interval specified by the heartbeat detection time interval information;

S5112, if the difference between the current time and the time of the last heartbeat packet reception is greater than 2× the time interval specified by the heartbeat detection time interval information, determine that the designated terminal is abnormal.

As described above, it is realized whether the designated terminal is abnormal according to the preset heartbeat abnormality judgment rule. The preset heartbeat abnormality judgment rule adopted in this embodiment is: whether the difference between the current time and the time of the last heartbeat packet reception is greater than 2×the time interval specified by the heartbeat detection time interval information. If the difference between the current time-the time of the last heartbeat packet reception is greater than 2 × the time interval specified by the heartbeat detection time interval information, the designated terminal is determined to be abnormal; if the difference between the current time-the time of the last heartbeat packet reception is not greater than 2×The time interval specified by the heartbeat detection time interval information, and it is determined that the designated terminal is normal.

As described in the foregoing unit 10, the intermediate server receives a heartbeat subscription request for a designated terminal sent by a consumer terminal, and the heartbeat subscription request carries heartbeat detection time interval information. In the network information transmission, the heartbeat mechanism is to send a custom structure (heartbeat packet, heartbeat information) at regular intervals to let the other party know that he is still alive to ensure the validity of the connection. The heartbeat state is divided into static (ie abnormal ) Or activity (ie normal). The heartbeat detection in this application is to use the heartbeat packet to detect whether the designated terminal is abnormal. The heartbeat packet in this embodiment may be any heartbeat packet, for example, a heartbeat packet containing information such as a timestamp, a heartbeat interval, and a service IP. The consumer terminal refers to a terminal that consumes services of a designated terminal, that is, a terminal that interacts with the designated terminal, and the consumer terminal is, for example, any terminal such as a PC terminal or a mobile phone terminal. The designated terminal refers to a terminal or a server terminal that interacts with the consumer terminal, such as a social software server, a weather information providing server, etc. The heartbeat subscription request refers to a request for obtaining a heartbeat packet of a specified terminal according to the heartbeat detection time interval information. Wherein, the consumer terminal and the designated terminal are relative terms, that is, when a terminal (or server) requires another terminal (or server) to detect the heartbeat, the certain terminal (or server) is the consumer Terminal, correspondingly, the other terminal (or server) is the designated terminal; otherwise, the certain terminal (or server) is the designated terminal, and correspondingly, the other terminal (or server) is the consumer terminal.

As described in the aforementioned unit 20, the number of consumer terminals that send the heartbeat subscription request is counted, and it is determined whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold. The heartbeat mechanism in the prior art is to perform direct heartbeat detection between a consumer terminal and a designated terminal. This kind of heartbeat detection needs to send and receive heartbeat packets through an HTTP request each time. When the number of consumer terminals is large, the heartbeat detection The overhead will make the designated terminal unbearable. Therefore, this embodiment counts the number of consumer terminals that send the heartbeat subscription request, and determines whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold, so as to determine whether the specified terminal can tolerate If the overhead of heartbeat detection in the prior art cannot be tolerated, an intermediate server is used for transfer instead of sending heartbeat packets to different consumer terminals. If it can be tolerated, the heartbeat packet is sent and received directly through HTTP requests. can. The method for determining whether the designated terminal can tolerate the overhead of heartbeat detection in the prior art is achieved by determining whether the number of consumer terminals that send the heartbeat subscription request is greater than a preset heartbeat subscription number threshold.

As described in the foregoing unit 30, if the number of consumer terminals that send the heartbeat subscription request is greater than the preset heartbeat subscription number threshold, a heartbeat packet acquisition request is sent to the designated terminal. As mentioned above, it can be seen that if the number of consumer terminals sending the heartbeat subscription request is greater than the preset heartbeat subscription number threshold, indicating that the specified terminal cannot tolerate the overhead of heartbeat detection in the prior art, the heartbeat packet can be transferred through the intermediate server. Accordingly, the intermediate server sends a heartbeat packet acquisition request to the designated terminal, thereby requiring the designated terminal to send a heartbeat packet.

As described in the foregoing unit 40, the heartbeat packet sent by the designated terminal according to the heartbeat packet acquisition request is received. The heartbeat packet sent by the designated terminal may be sent at predetermined intervals, and the predetermined time may be set by the designated terminal, or may be set by the designated terminal according to a predetermined time set by the intermediate server, or may be set by the designated terminal. The designated terminal is set according to the heartbeat detection time interval information carried in the heartbeat subscription request. According to this, a heartbeat packet is received.

As described in the aforementioned unit 50, the heartbeat packet is sent to the consumer terminal that sends the heartbeat subscription request according to the time interval specified by the heartbeat detection time interval information. Since the heartbeat subscription request sent by the consumer terminal to the specified terminal carries the heartbeat detection time interval information, that is, the consumer terminal requires the heartbeat detection time interval, so the heartbeat packet is sent according to the heartbeat detection time interval to complete the heartbeat packet send. The consumer terminal receiving the heartbeat packet can complete the heartbeat detection according to the heartbeat packet to determine the status of the designated terminal (abnormal or normal), and then determine the subsequent instructions according to the status of the designated terminal (for example, if the designated terminal is abnormal, disconnect The connection with the designated terminal, or re-verify the login account, etc.). In addition, this application adopts the time interval specified by the heartbeat detection time interval information from the consumer terminal. First, the intermediate server does not need to set the time interval, thereby reducing the procedure and improving the efficiency; and the heartbeat detection time interval information set by the consumer terminal itself is more It is adapted to the consumer terminal itself, so different consumer terminals can achieve different and most appropriate time intervals, thereby making the heartbeat detection method more flexible.
