Referring to FIG. 1, a flow diagram of one embodiment of a service instance access method according to the present disclosure is shown. The service instance access method as shown in fig. 1 comprises the following steps:
step 101, a first access request for a first service is received.
In this embodiment, an electronic device executing the service instance access method may receive a first access request for a first service.
The first access request may be an access request requesting access to the first service.
In some scenarios, the first access request may be an access request sent by a server at which an upstream service of the first service resides. That means that when the first service needs to be accessed, the server where the upstream service of the first service is located may send the first access request to the electronic device executing the service instance access method.
In other scenarios, the first access request may be an access request sent by the user's electronic device (terminal device or server). The method includes that a user can execute corresponding triggering operation, and the electronic equipment of the user is triggered to send a first access request to the electronic equipment executing the service instance access method.
Step 102, determining whether the first access request includes test indication information of the second service.
In this embodiment, after receiving the first access request, the electronic device executing the service instance access method may determine whether the first access request includes test instruction information of the second service
The second service may be a downstream service of the first service. That is, the second service may be a service at a location downstream from the first service.
The test instruction information may be information indicating that the service instance that is not online for the service is tested. It is to be appreciated that the non-online service instance can be a service instance that is not deployed in a micro-service architecture.
In some scenarios, an electronic device executing the service instance access method may determine, at a preset location of the first access request, whether test indication information of the second service is included. The preset location may be, for example, a location where the custom field in the first access request is located, and may also be, for example, a request header of the first access request.
In some alternative implementations, the test indication information may include a service name of the service. Accordingly, the test indication information of the second service may include a service name of the second service. At this time, the electronic device performing the service instance access method may perform step 102 as follows.
First, in response to determining that the test instruction information is included in the first access request, the electronic device executing the service instance access method may determine whether the service name included in the test instruction information in the first access request is the service name of the second service.
In some scenarios, an electronic device executing the service instance access method may determine whether the first access request includes test indication information. If the first access request includes the test indication information, the electronic device executing the service instance access method may further determine whether the service name included in the test indication information is the service name of the second service.
Then, in response to determining that the service name included in the test instruction information in the first access request is the service name of the second service, the electronic device executing the service instance access method may determine that the test instruction information of the second service is included in the first access request.
In these alternative implementations, the service name is set in the access request, so that during the process of the first service accessing the second service, by determining whether the first access request contains the service name of the second service, it is determined whether the first access request contains the test indication information of the second service.
Step 103, in response to determining that the first access request includes the test indication information of the second service, a first service address of an offline service instance of the second service is obtained.
In this embodiment, in response to determining that the first access request includes the test instruction information of the second service, the electronic device executing the service instance access method may acquire the first service address of the non-online service instance of the second service.
The service address may be an address of a service instance deployment. Accordingly, the first service address may be an address of an off-line service instance deployment of the second service. It is understood that an off-line service instance of the second service may provide the second service under the first service address. In practice, the service address may contain an IP address (Internet Protocol Address ) and a port number.
In some scenarios, an electronic device executing the service instance access method may obtain a first service address of an off-line service instance of a second service from a local or communicatively connected database server.
In some alternative implementations, the test indication information may include a service address of an offline service instance of the service. Accordingly, the test indication information of the second service may include the address of the first service. At this time, the electronic device performing the service instance access method may perform step 103 as follows.
Specifically, the electronic device executing the service instance access method may obtain the service address of the non-online service instance of the second service from the test instruction information of the second service.
In these alternative implementations, the service address of the non-online service instance is set in the access request, whereby, during the process of the first service accessing the second service, the service address of the non-online service instance of the second service may be extracted from the first access request.
Step 104, sending a second access request to the server indicated by the first service address to access the non-online service instance of the second service.
In this embodiment, after the first service address is acquired, the electronic device executing the service instance access method may send a second access request to the server indicated by the first service address to access the offline service instance of the second service.
It will be appreciated that the server indicated by the first service address may be the server where the non-online service instance of the second service is located.
In some scenarios, after receiving the second access request, the server indicated by the first service address may verify the second access request. If the verification is passed, the electronic device executing the service instance access method can access the non-online service instance of the second service under the first service address.
Referring to fig. 2, an application scenario of a service instance access method according to an embodiment of the present disclosure is shown. As shown in fig. 2, first, a server 201 may receive a first access request 202 for a first service. The server 201 may then determine whether the first access request 202 contains test indication information 203 for the second service. Further, in response to determining that the first access request 202 includes the test indication information 203 for the second service, the server 201 may obtain the first service address 204 of the non-online service instance for the second service. Finally, the server 201 may send a second access request 206 to the server 205 indicated by the first service address 204, thereby accessing an offline service instance of the second service under the first service address 204.
In the related art, in order to implement the test of the non-online service instance, the non-online service instance may be tested separately at the server where it is located. It should be appreciated that the off-line service instance employs a separate test, even if the test passes, the probability of failure is high after deployment in the micro-service architecture because no associated test is performed with other services in the micro-service architecture.
In this embodiment, if it is determined that the first access request includes the test indication information of the second service, the first service address of the non-online service instance of the second service may be obtained. Further, a second access request may be sent to the server indicated by the first service address, to enable access to an offline service instance of the second service. As can be seen from the above, in the micro-service architecture, when the first service accesses the second service, if it is determined that the first access request includes the test indication information of the second service, the first service may access the non-online service instance of the second service, that is, the second service is provided through the non-online service instance of the second service. Therefore, in the process that the first service accesses the second service, the test of the non-online service instance of the second service is completed, namely, the association test of the non-online service instance of the second service and the online service in the micro-service architecture is realized. The correlation test of the online service in the micro-service architecture can improve the test accuracy of the non-online service instance of the second service, thereby reducing the probability of failure of the non-online service instance of the second service after being deployed in the micro-service architecture.
With continued reference to FIG. 3, a flow of yet another embodiment of a service instance access method according to the present disclosure is shown. As shown in fig. 3, the service instance access method includes the following steps:
step 301, a first access request for a first service is received.
Step 302, determining whether the first access request includes test indication information of the second service.
In this embodiment, if it is determined that the first access request includes the test instruction information of the second service, the electronic device executing the service instance access method may continue to execute steps 303 and 304. If it is determined that the first access request does not include the test instruction information of the second service, the electronic device executing the service instance access method may continue to execute steps 305, 306 and 307.
Step 303, in response to determining that the first access request includes the test indication information of the second service, a first service address of an offline service instance of the second service is obtained.
Step 304, sending a second access request to the server indicated by the first service address to access the offline service instance of the second service.
The steps 301, 302, 303, 304 may be performed in a similar manner as the steps 101, 102, 103, 104 in the embodiment shown in fig. 1, and the descriptions of the steps 101, 102, 103, 104 are also applicable to the steps 301, 302, 303, 304, which are not repeated herein.
In step 305, in response to determining that the first access request does not include the test indication information of the second service, a target online service instance is determined from a plurality of online service instances of the second service.
In this embodiment, in response to determining that the first access request does not include the test instruction information of the second service, the electronic device executing the service instance access method may determine the target online service instance from among a plurality of online service instances of the second service.
The online service instance may be a service instance that has been deployed in a micro-service architecture. Accordingly, the online service instance of the second service may be a service instance of the second service that has been deployed in the micro-service architecture.
The target online service instance may be a service instance of a second service to be accessed.
In some scenarios, an electronic device executing the service instance access method may randomly determine one service instance from a plurality of online service instances of a second service as a target online service instance.
In some alternative implementations, the electronic device performing the service instance access method may perform step 305 as follows.
First, an electronic device executing the service instance access method may acquire registration information of each of a plurality of online service instances of the second service.
The registration information may be information registered by the online service instance at a registry. The registration information may include: service name of the service to which the online service instance belongs, service address of the online service instance, working status of the online service instance, and the like.
The operating state of the online service instance may include: state accessed by other services, idle state.
The registry may be a storage space in the micro-service architecture that stores mappings between services and service addresses of service instances. For example, the service a has a service instance A1 and a service instance A2, the service address of the service instance A1 is D1, and the service address of the service instance A2 is D2, and then the registry may store the mapping relationship between the service a and the service addresses D1 and D2.
In some scenarios, the electronic device executing the service instance access method may acquire, in advance, registration information of each online service instance of the second service from a server where the registry is located. At this time, the electronic device performing the service instance access method may directly acquire registration information of each online service instance of the second service from the local.
In another scenario, an electronic device executing the service instance access method may obtain registration information for each online service instance of the second service from a server where the registry is located.
Then, the electronic device executing the service instance access method may determine a target online service instance from a plurality of online service instances of the second service according to the acquired plurality of registration information and the preset load balancing policy.
The load balancing policy may be a policy set for adjusting load balancing of servers where online service instances in the micro service architecture are located.
In some scenarios, the electronic device executing the service instance access method may analyze the acquired multiple registration information according to a preset load balancing policy, so as to determine the target online service instance on the premise of meeting the load balancing of the server where the multiple online service instances of the second service are located.
In these alternative implementations, the target online service instance is determined through the registration information and the load balancing policy, where the target online service instance for providing the second service may be determined on the premise of satisfying load balancing of the servers where the plurality of online service instances of the second service are located.
Step 306, a second service address of the target online service instance is obtained.
In this embodiment, after determining the target online service instance, the electronic device executing the service instance access method may acquire the second service address of the target online service instance.
The second service address may be an address of a target online service instance deployment. Meaning that the target online service instance of the second service may provide the second service at the second service address.
In some scenarios, an electronic device executing the service instance access method may obtain a second service address of a target online service instance from a local or registry.
Step 307, a third access request is sent to the server indicated by the second service address to access the target online service instance.
In this embodiment, after the second service address is acquired, the electronic device executing the service instance access method may send a third access request to the server indicated by the second service address to access the target online service instance.
It will be appreciated that the server indicated by the second service address may be the server where the target online service instance is located.
In some scenarios, after receiving the third access request, the server indicated by the second service address may verify the third access request. If the verification is passed, the electronic device executing the service instance access method can access the target online service instance of the second service under the second service address.
In some alternative implementations, the second access request or the third access request may include test indication information extracted from the first access request.
In these alternative implementations, the second access request or the third access request includes the slave test indication information, which means that, during the process that the first service accesses the second service, the test indication information included in the first access request is transferred to the second access request or the third access request. Thus, during the process of the second service accessing the downstream service, the server where the second service is located may test the offline service instance of the downstream service of the second service in a manner similar to that described in the embodiment shown in fig. 1 or that described in the embodiment shown in fig. 3. Therefore, the test of one or more off-line service instances in the micro-service architecture is realized by transmitting the test indication information contained in the access request.
In this embodiment, if it is determined that the first access request does not include the test indication information of the second service, the target online service instance is determined from the multiple online service instances of the second service, and in the process that the first service accesses the second service, the service instance that provides the second service may be determined from the multiple online service instances of the second service. Further, the second service address of the target online service instance is obtained, and the third access request is sent to the server indicated by the second service address, so that the target online service instance of the second service can provide the second service on the premise that the first access request does not contain the test indication information of the second service. Thus, in the process that the first service accesses the second service, if the first access request contains the test instruction information of the second service, the non-online service instance of the second service is accessed, and if the first access request does not contain the test instruction information of the second service, the online service instance of the second service target is accessed. Therefore, on the premise that the first service accesses the second service in the micro-service architecture, the association test of the non-online service instance of the second service and the first service is realized.
With further reference to fig. 4, as an implementation of the method shown in the foregoing figures, the present disclosure provides an embodiment of a service instance access apparatus, where an embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 1, and the apparatus may be specifically applied in various electronic devices.

The acquisition unit 403 may be further configured to: and acquiring the service address of the non-online service instance of the second service from the test indication information of the second service.
In some alternative implementations, the test indication information may include a service name of the service. The determining unit 402 may be further configured to: in response to determining that the first access request contains the test indication information, determining whether a service name contained in the test indication information in the first access request is a service name of the second service; in response to determining that the service name included in the test instruction information in the first access request is the service name of the second service, the test instruction information of the second service is included in the first access request.
In some alternative implementations, the service instance access apparatus may further include a second access unit (not shown in the figure). The second access unit may be for: in response to determining that the first access request does not include the test indication information of the second service, determining a target online service instance from a plurality of online service instances of the second service; acquiring a second service address of the target online service instance; and sending a third access request to the server indicated by the second service address to access the target online service instance.

The server 501 may be the server where the first service is located. The server 503 may be a server where an off-line service instance of the second service is located. The second service may be a service downstream of the first service. The access of the second service may be involved in the process of the first service being accessed.
In some scenarios, a server at which a service upstream of a first service resides may send a first access request to server 501 to access the first service. Upon receiving the first access request, the server 501 may determine whether the first access request includes test indication information of the second service. If it is determined that the first access request includes the test indication information of the second service, the server 501 may obtain the first service address of the non-online service instance of the second service. It is understood that the first service address may be a service address of an off-line service instance of the second service in the server 503. Further, the server 501 may send a second access request to the server 503 to enable access to an off-line service instance of the second service.

In some implementations, the servers may communicate using any currently known or future developed network protocol, such as HTTP (HyperText Transfer Protocol ), and may be interconnected with any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network ("LAN"), a wide area network ("WAN"), the internet (e.g., the internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks), as well as any currently known or future developed networks.
The computer readable medium may be contained in the electronic device; or may exist alone without being incorporated into the electronic device.
The computer readable medium carries one or more programs which, when executed by the electronic device, cause the electronic device to: receiving a first access request for a first service; determining whether the first access request contains test indication information of the second service; responding to the test indication information of the second service contained in the first access request, and acquiring a first service address of an off-line service instance of the second service; and sending a second access request to the server indicated by the first service address to access the non-online service instance of the second service.
Computer program code for carrying out operations of the present disclosure may be written in one or more programming languages, including, but not limited to, an object oriented programming language such as Java, smalltalk, C ++ and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computer (for example, through the Internet using an Internet service provider).
The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosure. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The units involved in the embodiments of the present disclosure may be implemented by means of software, or may be implemented by means of hardware. Where the name of the unit does not constitute a limitation of the unit itself in some cases, for example, the receiving unit may also be described as a unit "receiving a first access request for a first service".
The functions described above herein may be performed, at least in part, by one or more hardware logic components. For example, without limitation, exemplary types of hardware logic components that may be used include: a Field Programmable Gate Array (FPGA), an Application Specific Integrated Circuit (ASIC), an Application Specific Standard Product (ASSP), a system on a chip (SOC), a Complex Programmable Logic Device (CPLD), and the like.
In the context of this disclosure, a machine-readable medium may be a tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. The machine-readable medium may be a machine-readable signal medium or a machine-readable storage medium. The machine-readable medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.
The foregoing description is only of the preferred embodiments of the present disclosure and description of the principles of the technology being employed. It will be appreciated by persons skilled in the art that the scope of the disclosure referred to in this disclosure is not limited to the specific combinations of features described above, but also covers other embodiments which may be formed by any combination of features described above or equivalents thereof without departing from the spirit of the disclosure. Such as those described above, are mutually substituted with the technical features having similar functions disclosed in the present disclosure (but not limited thereto).
Moreover, although operations are depicted in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order. In certain circumstances, multitasking and parallel processing may be advantageous. Likewise, while several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of the present disclosure. Certain features that are described in the context of separate embodiments can also be implemented in combination in a single embodiment. Conversely, various features that are described in the context of a single embodiment can also be implemented in multiple embodiments separately or in any suitable subcombination.
