Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
the invention provides a service process calling method based on an internet of things cloud platform, wherein the internet of things cloud platform comprises a server end and an equipment end, the embodiment describes a specific embodiment of the service process calling method based on the internet of things cloud platform from the perspective of matching of the server end and the equipment end, and as shown in fig. 1, the specific service process calling process comprises the following steps:
in an optional implementation, the device side starts a service process, may start multiple service processes simultaneously, or may start one service process, and when multiple service processes are started, the registration information of the started multiple service processes is reported simultaneously.
The registration information includes a service process identifier and an equipment end address, the service process identifier is used for uniquely identifying the service process, and the equipment end address is used for uniquely identifying an equipment end where the service process is located.
as an optional implementation manner, when receiving registration information of a service process reported when a device side starts the service process under an internet of things cloud platform, a server side receives registration information of the service process respectively reported when different device sides start the same service process under the internet of things cloud platform.
optionally, the server may store the registration information of the service process in global service list information in a service discovery storage database, etc, where the service discovery storage database, etc, is a key-value storage repository and is used for configuration sharing and service discovery.
Optionally, when the server indicates, through the first indication information, that all the device sides in the internet of things cloud platform update the local global service list information synchronously:
in the optional specific implementation process, for a device end which starts a service process, a server end sends first indication information carrying global service list information to indicate the device end to locally store registration information of all service processes in the global service list information;
in an optional embodiment, for the device end that starts a service process and has only one service process, the global service list information carried by the first indication information does not include registration information of the service process; for the device end with more than one service process for starting the service process, the global service list information carried by the first indication information contains the registration information of all the service processes;
in a specific implementation process that can be selected, for a device side except for a device side that starts a service process under the internet of things cloud platform, when a server side receives registration information reported by the service process, the server side stores the registration information in a service discovery storage database (ETCD) and creates a credit trigger event carrying the registration information of the started service process, and the server side notifies the device side except for the device side that starts the service process through the credit trigger event, and adds the registration information of the started service process in local global service list information. That is, when a certain service process is started, first indication information is detected in all other service processes on the internet of things cloud platform, and registration information of the started service process is added to the equipment end where the service process is respectively located.
optionally, in a specific implementation process, for an equipment end that starts a service process, receiving first indication information that is sent by a server end and carries the global service list information, and locally storing registration information of all service processes in the global service list information at the equipment end, that is, enabling the service process to report the registration information to the server end when starting, and apply for and obtain registration information of other service processes from the server end;
in a specific implementation process, for a device side except for a device side for starting a service process under the internet of things cloud platform, a credit trigger event which is sent by a server side and carries registration information of the started service process is received, and the registration information of the started service process is added to local global service list information according to the registration information of the started service process carried by the credit trigger event.
optionally, any device side of the internet of things platform searches all device side addresses consistent with the service process identifier of the called service process in the local global service list information according to the service process identifier of the called service process, and selects any one of the device side addresses to write into a configuration file of the service process called by the device side for the service process;
executing the configuration file, and sending a service process calling request carrying the equipment end address to a server end;
as an optional implementation manner, the called service process may be placed at different device ends, in this case, the called service process having the same service process identifier has multiple different device ends, and when the called service process is called, if the called service process of a certain device end is abnormal and cannot be called or global service list information stored by the ETCD is damaged, the called service processes of other device ends may still be called, thereby effectively solving the single point load problem, ensuring that the called service process may be correctly called, and greatly improving the success rate of calling the service process.
And step 160, the server receives the service process calling request sent by the device side, and calls the service process according to the device side address carried by the service process calling request.
In the service process calling method based on the cloud platform of the internet of things, the device end stores the global service list information in the local, when the service process is called, the device end where the service process is located searches the device end address of the called service process from the local global service list information according to the service process identification of the called service process, automatically writes the device end address into the configuration file of the called service process, executes the configuration file, sends the service process calling request to the server end, and carries out correct service process calling, so that the waste of manually modifying the configuration file when the service is called based on the configuration file is solved.
In the process of calling the service process, the global service list information is automatically searched, and the equipment terminal address of the called service process is automatically written into the configuration file, so that the accuracy of calling the service process is improved.
In the process of calling the service process, the address of the equipment end of the service process of the internet of things cloud platform changes in some scenes, for example, when the equipment end where the service process is located is disconnected from the internet of things cloud platform due to re-registration or failure, an IP address is re-allocated, and the IP address of the service process on the equipment end changes. In this case, if a service process needs to be called, an operation and maintenance person needs to query a new address of the device side, and needs to manually modify the device side address of the called service process in a configuration file of the service process, and this way of manually modifying the configuration file brings a very large manpower overhead to operation and maintenance management, and has a high error rate, thereby greatly affecting the stability of the internet of things cloud platform.
In an optional implementation case, based on the content of the first embodiment, the registration information of the service process, which is reported when the device side starts the service process, is used as a possible optional implementation manner when the registration information includes the service process identifier and the device side address. Step 121, the equipment end which starts the service process sets a reporting period at intervals to report the state information of the started service process;
the state information is used for reporting the state of the started service process to the server side, the specific form and the carried content of the state information are not limited too much, and a person skilled in the art can set the state information according to actual requirements, wherein in an optional case, the state information in the embodiment is heartbeat;
the heartbeat sets a very small data packet sent to the server side for the started service process in a reporting period, and the server side judges whether communication links among the server side and the server side are disconnected or not through the data packet;
the set reporting period is not limited too much, and the set reporting period in this embodiment is a time interval of 1 time/20 milliseconds, which can be set by a person skilled in the art according to actual requirements.
Step 131, when the server receives the state information reported by the device, determines that the state information of any service process in the global service list information exceeds a set time and is not reported, deleting the registration information corresponding to the service process from the global service list information, and indicating all the device terminals under the internet of things cloud platform to synchronously update the local global service list information through second indication information;
the setting time is not particularly limited, and can be set by a person skilled in the art according to actual requirements;
in an optional real-time situation, the second indication information may be a credit update event carrying registration information of a service process with a lost heartbeat;
when the equipment end of the service process is in a power-off phenomenon and the address of the equipment end is changed, the address of the equipment end of the service process of the equipment end is changed, the corresponding state information is lost, and when the server end does not detect the heartbeat information within the set time, the registration information of the service process corresponding to the heartbeat information is deleted from the global service list; and creating a Creat update event carrying registration information of the service process with lost heartbeat information, and indicating the equipment terminal where other service processes on the Internet of things cloud platform are located to update local global service list information.
Step 141, when any device side of the internet of things platform receives the second indication information sent by the server side after deleting the registration information of the service process in the global service list, deleting the registration information of the corresponding service process in the local global service list information.
When any equipment end connected to the Internet of things cloud platform exits the Internet of things cloud platform due to network failure to re-log in the platform, or the equipment end fails to restart the login platform, or a user actively logs out the platform and then re-logs in the platform, the equipment end address of the service process of the equipment end is changed, and at the moment, the registration information of the service process of the equipment end needs to be deleted so as to be called by other service processes correctly.
Step 151, when other service processes of the internet of things cloud platform detect a credit update event carrying heartbeat loss, updating global service list information at the equipment end where the service processes are located, and deleting registration information of the service processes corresponding to the heartbeat;
the method in the embodiment also solves the problem of single-point load balancing, the same service process is respectively placed at different equipment ends, and when global service list information stored by the ETCD or global service information locally maintained by a certain service process is damaged, correct calling of other service processes can still be realized.
The following is an optional implementation of the above implementation of the correct invocation of other service processes:
in this embodiment, taking an example that after the device side where the service process 2 is located is restarted, the service process 3 calls the service process 2, a calling process of the service process after the device side address of the service process on the internet of things cloud platform changes is described.
In this embodiment, 3 identical service processes 2 are selected to be stored in different device ends, i.e., the device end 1, the device end 2 and the device end 3, the service process identifiers of the 3 service processes 2 are identical and are all the service processes 2, but the device end addresses are different, and the device end addresses of the service processes 2 in the device end 1, the device end 2 and the device end 3 are 192.168.1.119,192.168.2.34 and 192.168.3.25, respectively; the equipment end 4 runs the service process 3, and when the local service process is started, the equipment end 1, the equipment end 2, the equipment end 3 and the equipment end 4 report the registration information of the started service process to the server end, and the server end stores the received registration information of the service process in a global service list and synchronously updates all local service lists of each equipment end; the service processes 2 and 3 distributed on the device side 1, the device side 2 and the device side 3 and the service processes 3 on the device side 4 are started to maintain periodic heartbeat.
When the service process 3 stored on the device end 4 needs to call the service process 2, at this time, the device end 1 is powered off and restarted, and is reconnected to the internet of things cloud platform after being restarted, and the specific process of calling the service process 2 by the service process 3 stored on the device end 4 is as follows:
1) when the server determines that the heartbeat corresponding to the service process 2 stored on the equipment end 1 exceeds the set time and is not reported, the server deletes the registration information corresponding to the service process 2 stored on the equipment end 1 in the ETCD from the global service list;
when the device end 1 is shut down, the service process 2 stored on the device end 1 stops running and stops refreshing heartbeat information, at this time, the server end cannot detect the heartbeat information corresponding to the service process 2, the registration information corresponding to the service process 2 is deleted in a global service list maintained by the server end, namely, the deleted server end address 192.168.1.119 and the service process identification information corresponding to the deleted server end address are deleted, and a Creat update event is sent to indicate the device end where other service processes are located to update the global service list information;
2) the device end 4, the device end 2 and the device end 3 under the internet of things cloud platform detect a credit update event respectively, learn that the heartbeat corresponding to the service process 2 on the device end 1 is lost, and delete the registration information of the service process 2 stored on the device end 1 in the local global service list information of the respective device ends respectively, that is, delete the address 192.168.1.119 of the service end and the identification information of the service process corresponding to the address.
3) The device side 1 restarts the assigned new device side address 192.168.1.122, and when the service process 2 is started, registration information of the service process 2 of the device side 1 is reported to the server side, wherein the registration information comprises a device side address 192.168.1.122 and a service process identification service process 2 corresponding to the device side address 192.168.1.122;
4) the server side adds the registration information reported after the restart of the equipment side 1 to the global service list information, and sends a corresponding Creat trigger event to indicate the equipment side where other service processes are located to update the global service list information;
5) the device end 4 where the service process 3 under the platform is located detects the credit trigger event, and updates the new registration information of the service process 2 stored on the device end 1 into the local global service list information;
6) when the service process 3 on the device side 4 calls the service process 2, firstly, the device side 4 searches device side addresses of corresponding registration information of all the service processes 2 of the platform in the locally updated global service list information according to the service process identifier of the service 2;
the searched device side addresses are 192.168.1.122,192.168.2.34 and 192.168.3.25;
7) the equipment terminal 4 where the service process 3 is located selects any searched equipment terminal address to write into the corresponding position of the configuration file, executes the configuration file, and realizes calling of the service process 2;
in this embodiment, if the service process 2 stored in the device 1 is not reconnected after being offline, the service process 3 on the device 4 can still find the device addresses 192.168.2.34 and 192.168.3.25 of the available service process 2 in the local global service list when calling the service process 2, select any one of the service addresses to write in the configuration file, execute the configuration file to call the service process 2, and effectively solve the efficiency of calling the single-point deployment service process.
Example two:
in this embodiment, an ETCD service registration discovery center is provided in an Internet of things platform, where functions of the ETCD service registration discovery center are implemented by a server, each service process is started and reports registration information to the ETCD service registration discovery center, global service list information of registration information of all other service processes is simultaneously stored according to an instruction of the ETCD service registration discovery center, the global service list information is stored in a local cache of a device end where the started service process is located, and when other service processes need to be called, an device end address of the called service process is searched from the global service list information stored by the device end and is requested to be called, in this embodiment, a service process 1 is taken as an example, see fig. 2, and optional specific implementation steps are as follows:
step 210, starting a service process 1 of an equipment end, reporting registration information of the service process 1 to an ETCD service registration discovery center, and maintaining a heartbeat at a set interval time;
when the service process 1 is started, firstly, connection is established with an ETCD service registration discovery center, and own registration information is sent to the ETCD service registration discovery center, wherein the registration information comprises a service process identifier of the service process 1 and an equipment terminal address of the service process 1;
meanwhile, the service process 1 maintains heartbeat which is consistent with the ETCD service registration discovery center at a time interval of 1 time/20 milliseconds, the heartbeat regularly sends a very small data packet to the service registration discovery center for the service process, whether communication links among the service process and the service process are disconnected or not is judged through the reply of the ETCD service registration discovery center, and the heartbeat of the service process 1 is guaranteed to be refreshed again within the TTL time (survival time) of the ETCD service registration discovery center;
in this embodiment, a plurality of service processes 1 at different device ends may simultaneously initiate registration with the etc service registration discovery center as a highly available solution.
Step 220, the ETCD service registration discovery center reports the state of the service process 1 according to the registration information and the heartbeat, and instructs all equipment terminals to synchronously update the global service list when determining that the global service list needs to be updated;
the ETCD service registration discovery center receives registration information of a service process 1 reported when the service process is started, stores the registration information of the service process 1 into global service list information of the ETCD service registration discovery center, and indicates all equipment terminals under the Internet of things cloud platform to synchronously update the local global service list information through first indication information;
in the specific implementation process, for the equipment end where the service process 1 is located, the server end sends first indication information carrying registration information of other service processes (service processes 2,3 and 4) of the internet of things cloud platform, and notifies the equipment end to locally store global service list information;
for the device side where other service processes (service processes 2,3,4) than the service process 1 in the internet of things cloud platform are located, in this embodiment, when the ETCD service registration discovery center detects a registration heartbeat sent by the service 1, the ETCD service registration discovery center generates a Create trigger event corresponding to the service process 1, and the ETCD service registration discovery center instructs, according to the Create trigger event, the other service processes (service processes 2,3,4) in the internet of things cloud platform to store the registration information of the service process 1 in the global service list information of the device side where the other service processes are located.
When the ETCD service registration discovery center detects that the heartbeat corresponding to the service process 1 is lost, the ETCD service registration discovery center deletes the registration information of the service process 1 from the global service list information, and instructs all equipment terminals under the Internet of things cloud platform to synchronously update the local global service list information through a Creat update event;
in this embodiment, when the ETCD service registration detects that the heartbeat corresponding to the service process 1 is lost, the ETCD service registration discovery center generates a Create update event corresponding to the service process 1 with the lost heartbeat;
and the ETCD service registration discovery center instructs other service processes (service processes 2,3 and 4) of the Internet of things cloud platform to delete the registration information of the service process 1 with the lost heartbeat from respective local global service list information at the respective equipment end according to the Creat updating event.
