Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a state determination method, an electronic device, a system, and a medium.
Background
The HyperText Transfer Protocol (HTTP) and/or the HyperText Transfer Protocol Security (HTTPs) are the most widely used network communication protocols on the internet, and applications based on the browser Web (World Wide Web) end rely on the protocols to communicate with the server end. The protocol is based on a "client request-server response" mode, and therefore, the status of the client cannot be judged by the protocol. Although the server has a great number of mature open-source network servers capable of providing network services, the client initiates a request, and the server returns corresponding files, data, interface services and the like. In this mode, the internet application provider can quickly construct a set of network applications with extremely low development and development technology cost. However, since the protocol is a stateless short connection protocol, it will not meet the requirements when a persistent state like "online" needs to be implemented.
In the prior art, the long connection TCP (Transmission Control Protocol) technology based on a non-browser end or a long connection technology such as a WebSocket at a browser end is generally adopted. However, the above solutions also have certain disadvantages.
Under the widely used browser web application scene, the TCP protocol cannot be supported, and the use of the WebSocket long connection has the following problems:
(1) the technical research and development cost of the client and the server is improved;
(2) a large number of long connections may consume excessive server resources;
(3) the part of the browser end does not support the WebSocket protocol;
(4) in a non-browser scenario, for example, when a mobile application (App) side accesses a server side through a hypertext transfer protocol and/or a hypertext transfer security protocol, the WebSocket protocol cannot be directly used.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides a state determination method.
Referring to fig. 1, fig. 1 is a schematic flow chart according to an embodiment of the invention. The order of the steps in the flow diagram can be changed and some steps can be omitted according to different requirements.
The state determination method is applied to one or more electronic devices, which are devices capable of automatically performing numerical calculation and/or information processing according to preset or stored instructions, and the hardware of the electronic devices includes, but is not limited to, microprocessors, Application Specific Integrated Circuits (ASICs), Programmable Gate arrays (FPGAs), Digital Signal Processors (DSPs), embedded devices, and the like.
The electronic device may be any electronic product capable of performing human-computer interaction with a user, for example, a Personal computer, a tablet computer, a smart phone, a Personal Digital Assistant (PDA), a game machine, an interactive Internet Protocol Television (IPTV), an intelligent wearable device, and the like.
The electronic device may also include a network device and/or a user device. The network device includes, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a Cloud Computing (Cloud Computing) based Cloud consisting of a large number of hosts or network servers.
The Network where the electronic device is located includes, but is not limited to, the internet, a wide area Network, a metropolitan area Network, a local area Network, a Virtual Private Network (VPN), and the like.
In one embodiment, the method comprises:
s10, when the heartbeat request is detected, using a HyperText Transfer Protocol (HTTP) and/or a HyperText Transfer security Protocol (HTTPs) to receive the heartbeat request.
In at least one embodiment of the present invention, the heartbeat request is based on a heartbeat mechanism, which is a mechanism that sends a self-defined structure (heartbeat packet, i.e. the heartbeat request) periodically to let the other side know that the other side is still alive, so as to ensure the validity of the connection.
Specifically, the heartbeat request is typically a very small packet or a null packet that includes only a header.
In at least one embodiment of the present invention, the hypertext transfer protocol and/or hypertext transfer security protocol is a short connection protocol. Moreover, when the hypertext transfer protocol and/or the hypertext transfer security protocol are/is used for connection, the online or offline state of the client cannot be acquired, and the statistical analysis of the user use state or the client connection state cannot be performed.
In at least one embodiment of the invention, the method further comprises:
the electronic equipment acquires all connectable clients and determines the identification and the type of each client in all the clients, furthermore, the electronic equipment establishes a mark value of each client according to the identification and the type of each client and stores each mark value into a Cache server (Cache server), and the electronic equipment configures a heartbeat cycle and a Cache validity period for each mark value.
For example: the flag value may be configured as a key and may be a value. At this time, if the identifier of a client is a and the type of the client is x, the flag value of the client is set to a _ x.
Specifically, the cache server refers to a server storing frequently accessed content. The cache server can automatically clear redundant data, and avoids causing the shortage of server resources and influencing the normal operation of the server.
Further, the client initiates the heartbeat request periodically according to the heartbeat cycle, and the heartbeat cycle can be configured by user, which is not limited in the present invention. For example: the heartbeat period may be 30 seconds, 1 minute, 3 minutes, etc., and the length of the heartbeat period will affect the throughput of the heartbeat request and the delay of the offline status update.
Accordingly, in order to more effectively determine the status of the client, the cache validity period is configured to be a value greater than the heartbeat cycle. For example: when the heartbeat period is 30 seconds, the cache validity period may be configured to be 60 seconds.
In at least one embodiment of the invention, the identification of each client may include, but is not limited to, a combination of one or more of the following:
(1) in a product in a user login state, a client generally has a token (token) indicating a login identity, and through the token, the electronic device can obtain a unique identifier such as a currently logged-in user id (identification) as an identifier of the client.
(2) In products without user login status, the configuration protocol is agreed, for example: for mobile devices such as mobile phones and tablet computers, the device number may be used as the identifier of the client, and for web browsers, the client IP (Internet Protocol Address) may be used as the identifier of the client.
In at least one embodiment of the present invention, since a user may be online on different types of devices such as a pc (personal computer) terminal, a Web browser (World Wide Web), a mobile phone app, a tablet app, and the like, when it is necessary to distinguish which terminal the user is online, the type of the client needs to be determined, and therefore, the electronic device establishes a tag value of each client with the type of the client as a parameter.
And S11, acquiring the heartbeat parameters from the heartbeat request.
In at least one embodiment of the present invention, the heartbeat parameter is included in the heartbeat request.
Further, the heartbeat parameter includes an identification of a target client and a type of the target client.
The target client is the client which is performing state judgment.
And S12, detecting the target mark value corresponding to the heartbeat parameter in the cache server to obtain a detection result.
In at least one embodiment of the present invention, the detection result includes, but is not limited to, any one of the following cases:
(1) the target tag value is present.
(2) The target flag value is not present.
It is understood that, for different detection results, the electronic device will make different judgments on the status of the target client.
And S13, judging the state of the target client corresponding to the heartbeat parameter according to the detection result.
In at least one embodiment of the present invention, the determining, by the electronic device according to the detection result, the state of the target client corresponding to the heartbeat parameter includes:
(1) when the target mark value is detected to exist, the electronic equipment determines that the target client is in an online state.
For example: when a key a _ x in the cache server exists, the electronic device determines that a is currently online and the online device type is x.
(2) When detecting that the target mark value does not exist, the electronic device determines that the target client is in an offline state.
For example: when the key a _ x in the cache server does not exist, the electronic device determines that a is in an offline state on device type x.
Through the embodiment, the electronic equipment can automatically judge the state of the client.
In at least one embodiment of the present invention, after determining, according to the detection result, a state of the target client corresponding to the heartbeat parameter, the method further includes:
and the electronic equipment acquires a target heartbeat cycle and a target caching validity period of the target mark value from the cache server, calculates a difference value between the target caching validity period and the target heartbeat cycle, and establishes a misjudgment time range corresponding to the state of the target client by taking the difference value as a minimum value and the target heartbeat cycle as a maximum value.
For example: after the target client is offline, a _ x in the cache server needs to wait for 60s (a heartbeat is sent just before offline) at the longest and expires after waiting for 30s (a heartbeat is ready to be sent just before offline) at the shortest, so that the target client is actually offline but is judged to be online in this period of time, a specific misjudgment time range m is related to the target heartbeat period t and the target cache validity period e, and the formula is as follows: e-t < m < e.
With the above embodiment, the electronic device can tolerate the delay of the offline state determination when the state determination of the client is performed.
In at least one embodiment of the invention, the method further comprises:
and the electronic equipment acquires the times of failure in receiving the heartbeat request, and when the times are less than or equal to a configuration value, the electronic equipment continues to judge the state of the target client.
It is understood that, if a certain heartbeat request process fails, the electronic device may determine the client as an offline state, and thus, in order to increase the fault tolerance of the heartbeat request failure to prevent misjudgment, the electronic device configures the number of times, that is, when the number of times is less than or equal to a configured value, the electronic device attempts to continue to determine the state of the target client, rather than directly determining the target client as the offline state.
For example: the number of times may be configured to be 2 or 3.
Specifically, the number of times may be configured as n ═ e/t-1, where e is the cache validity period and t is the heartbeat cycle.
Therefore, in order to increase the fault tolerance of the heartbeat request failure, a longer e may be configured, but the larger the value of e is, the larger n is, and the larger the false judgment range is. Over a large run of data, n can be configured to be 2 or 3, at which time e takes a minimum value.
For example: when t is 30s, when n is 2, e is 91 s; when n is 3, e is 121 s.
In at least one embodiment of the present invention, after determining the state of the target client corresponding to the heartbeat parameter, the method further includes:
(1) and calculating the total time length of the target client in the online state within a preset time range.
(2) And calculating the number of online days of the target client in an online state in the preset time range, determining the total number of days included in the preset time range, and calculating the online rate of the target client in the preset time range according to the number of online days and the total number of days.
(3) And acquiring all the clients, judging the state of each client in all the clients, and determining the number of online clients in an online state and the number of offline clients in an offline state in all the clients according to the state of each client.
Through the fact mode, the online time, the online rate, the online quantity and the like of a single user can be respectively counted, the online condition of the client side is conveniently analyzed, and the abnormal condition is conveniently maintained in time.
In summary, the present invention can adopt a hypertext transfer protocol and/or a hypertext transfer security protocol to accept a heartbeat request when the heartbeat request is detected, so as to establish a connection with a short connection protocol, obtain a heartbeat parameter from the heartbeat request, further detect a target flag value corresponding to the heartbeat parameter in a cache server, obtain a detection result, and determine a state of a target client corresponding to the heartbeat parameter according to the detection result, thereby implementing effective determination of a client state under the short connection protocol.

Fig. 3 is a functional block diagram of the state determination system according to the present invention. The state determination system 11 includes an accepting unit 110, an acquiring unit 111, a detecting unit 112, a determining unit 113, a determining unit 114, a establishing unit 115, a storing unit 116, a configuring unit 117, a calculating unit 118, and a constructing unit 119. The module/unit referred to in the present invention refers to a series of computer program segments that can be executed by the processor 13 and that can perform a fixed function, and that are stored in the memory 12. In the present embodiment, the functions of the modules/units will be described in detail in the following embodiments.
When a heartbeat request is detected, the receiving unit 110 receives the heartbeat request by using a HyperText Transfer Protocol (HTTP) and/or a HyperText Transfer Protocol Security (HTTPs).
In at least one embodiment of the present invention, the heartbeat request is based on a heartbeat mechanism, which is a mechanism that sends a self-defined structure (heartbeat packet, i.e. the heartbeat request) periodically to let the other side know that the other side is still alive, so as to ensure the validity of the connection.
Specifically, the heartbeat request is typically a very small packet or a null packet that includes only a header.
In at least one embodiment of the present invention, the hypertext transfer protocol and/or hypertext transfer security protocol is a short connection protocol. Moreover, when the hypertext transfer protocol and/or the hypertext transfer security protocol are/is used for connection, the online or offline state of the client cannot be acquired, and the statistical analysis of the user use state or the client connection state cannot be performed.
In at least one embodiment of the invention, the method further comprises:
the obtaining unit 111 obtains all connectable clients, the determining unit 114 determines an identifier and a type of each client in all the clients, further, the establishing unit 115 establishes a tag value of each client according to the identifier and the type of each client, the storage unit 116 stores each tag value into a Cache server (Cache server), and the configuring unit 117 configures a heartbeat cycle and a Cache validity period for each tag value.
For example: the flag value may be configured as a key and may be a value. At this time, if the identifier of a client is a and the type of the client is x, the flag value of the client is set to a _ x.
Specifically, the cache server refers to a server storing frequently accessed content. The cache server can automatically clear redundant data, and avoids causing the shortage of server resources and influencing the normal operation of the server.
Further, the client initiates the heartbeat request periodically according to the heartbeat cycle, and the heartbeat cycle can be configured by user, which is not limited in the present invention. For example: the heartbeat period may be 30 seconds, 1 minute, 3 minutes, etc., and the length of the heartbeat period will affect the throughput of the heartbeat request and the delay of the offline status update.
Accordingly, in order to more effectively determine the status of the client, the cache validity period is configured to be a value greater than the heartbeat cycle. For example: when the heartbeat period is 30 seconds, the cache validity period may be configured to be 60 seconds.
In at least one embodiment of the invention, the identification of each client may include, but is not limited to, a combination of one or more of the following:
(1) in a product in a user login state, a client generally has a token (token) indicating a login identity, and through the token, the obtaining unit 111 may obtain a unique identifier such as a currently logged-in user id (identification) as an identifier of the client.
(2) In products without user login status, the configuration protocol is agreed, for example: for mobile devices such as mobile phones and tablet computers, the device number may be used as the identifier of the client, and for web browsers, the client IP (Internet Protocol Address) may be used as the identifier of the client.
In at least one embodiment of the present invention, since a user may be online on different types of devices such as a pc (personal computer) side, a Web browser (World Wide Web), a mobile phone app, a tablet app, and the like, when it is necessary to distinguish which terminal the user is online, the type of the client needs to be determined, and therefore, the establishing unit 115 establishes the tag value of each client with the type of the client as a parameter.
The obtaining unit 111 obtains the heartbeat parameter from the heartbeat request.
In at least one embodiment of the present invention, the heartbeat parameter is included in the heartbeat request.
Further, the heartbeat parameter includes an identification of a target client and a type of the target client.
The target client is the client which is performing state judgment.
The detection unit 112 detects the target mark value corresponding to the heartbeat parameter in the cache server, and obtains a detection result.
In at least one embodiment of the present invention, the detection result includes, but is not limited to, any one of the following cases:
(1) the target tag value is present.
(2) The target flag value is not present.
It is understood that, for different detection results, different judgments will be made on the status of the target client.
Based on the detection result, determining section 113 determines the state of the target client corresponding to the heartbeat parameter.
In at least one embodiment of the present invention, the determining unit 113, according to the detection result, determining the state of the target client corresponding to the heartbeat parameter includes:
(1) when detecting that the target flag value exists, the determination unit 113 determines that the target client is in an online state.
For example: when the key a _ x in the cache server exists, the determining unit 113 determines that a is currently online and the online device type is x.
(2) When detecting that the target flag value does not exist, the determination unit 113 determines that the target client is in an offline state.
For example: when the key a _ x in the cache server does not exist, the determination unit 113 determines that a is in an offline state on the device type x.
With the above embodiment, the determination unit 113 can automatically determine the state of the client.
In at least one embodiment of the present invention, after determining, according to the detection result, a state of the target client corresponding to the heartbeat parameter, the method further includes:
the obtaining unit 111 obtains a target heartbeat cycle and a target cache validity period of the target mark value from the cache server, the calculating unit 118 calculates a difference between the target cache validity period and the target heartbeat cycle, and the constructing unit 119 constructs a misjudgment time range corresponding to the state of the target client by using the difference as a minimum value and the target heartbeat cycle as a maximum value.
For example: after the target client is offline, a _ x in the cache server needs to wait for 60s (a heartbeat is sent just before offline) at the longest and expires after waiting for 30s (a heartbeat is ready to be sent just before offline) at the shortest, so that the target client is actually offline but is judged to be online in this period of time, a specific misjudgment time range m is related to the target heartbeat period t and the target cache validity period e, and the formula is as follows: e-t < m < e.
With the above-described embodiment, the determination unit 113 can tolerate delay in determining the offline state when determining the state of the client.
In at least one embodiment of the invention, the method further comprises:
the obtaining unit 111 obtains the number of times of failure in receiving the heartbeat request, and when the number of times is less than or equal to a configuration value, the determining unit 113 continues to determine the state of the target client.
It is to be understood that, if a certain heartbeat request process fails, the determination unit 113 may determine the client as an offline state, and therefore, in order to increase the fault tolerance of the heartbeat request failure to prevent misjudgment, the configuration unit 117 configures the number of times, that is, when the number of times is less than or equal to a configured value, the determination unit 113 attempts to continue to determine the state of the target client, rather than directly determining the target client as an offline state.
For example: the number of times may be configured to be 2 or 3.
Specifically, the number of times may be configured as n ═ e/t-1, where e is the cache validity period and t is the heartbeat cycle.
Therefore, in order to increase the fault tolerance of the heartbeat request failure, a longer e may be configured, but the larger the value of e is, the larger n is, and the larger the false judgment range is. Over a large run of data, n can be configured to be 2 or 3, at which time e takes a minimum value.
For example: when t is 30s, when n is 2, e is 91 s; when n is 3, e is 121 s.
In at least one embodiment of the present invention, after determining the state of the target client corresponding to the heartbeat parameter, the method further includes:
(1) the calculating unit 118 calculates a total duration of time that the target client is in an online state within a preset time range.
(2) The calculating unit 118 calculates the number of online days in which the target client is online within the preset time range, the determining unit 114 determines the total number of days included in the preset time range, and the calculating unit 118 calculates the online rate of the target client within the preset time range according to the number of online days and the total number of days.
(3) The obtaining unit 111 obtains all the clients, the determining unit 113 determines a state of each of the clients, and the determining unit 114 determines the number of online clients in an online state and the number of offline clients in an offline state according to the state of each of the clients.
Through the fact mode, the online time, the online rate, the online quantity and the like of a single user can be respectively counted, the online condition of the client side is conveniently analyzed, and the abnormal condition is conveniently maintained in time.
In summary, the present invention can adopt a hypertext transfer protocol and/or a hypertext transfer security protocol to accept a heartbeat request when the heartbeat request is detected, so as to establish a connection with a short connection protocol, obtain a heartbeat parameter from the heartbeat request, further detect a target flag value corresponding to the heartbeat parameter in a cache server, obtain a detection result, and determine a state of a target client corresponding to the heartbeat parameter according to the detection result, thereby implementing effective determination of a client state under the short connection protocol.
