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 shown in fig. 1 includes the following steps:
In this embodiment, an electronic device executing a 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 a first service.
In some scenarios, the first access request may be an access request sent by a server on which an upstream service of the first service is located. That means, when the first service needs to be accessed, the server where the service upstream of the first service is located may send the first access request to the electronic device that performs 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). That means, the user may perform a corresponding trigger operation, which triggers the electronic device of the user to send the first access request to the electronic device performing the service instance access method.
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 indication 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 indication information may be information indicating that a non-online service instance of the service is to be tested. It is to be appreciated that the offline service instance can be a service instance that is not deployed in the microservice architecture.
In some scenarios, an electronic device executing the service instance access method may determine whether to include test indication information for the second service at a preset location of the first access request. The preset position may be, for example, a position 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 first access request includes the test indication information, the electronic device executing the service instance access method may determine whether a service name included in the test indication information in the first access request is a service name of the second service.
In some scenarios, an electronic device executing the service instance access method may determine whether test indication information is included in the first access request. 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 indication 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 indication 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, and thus, in the process of accessing the second service by the first service, it is determined whether the first access request includes the test indication information of the second service by determining whether the first access request includes the service name of the second service.
In this embodiment, in response to determining that the first access request includes the test indication information of the second service, the electronic device executing the service instance access method may acquire the first service address of the offline 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 a second service that is not deployed to an online service instance. It is to be appreciated that an offline service instance of the second service can provide the second service under the first service address. In practice, the service Address may include an IP Address (Internet Protocol Address) and a port number.
In some scenarios, an electronic device performing a service instance access method may obtain a first service address of an offline 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 a service address of an offline service instance of the second service from the test indication information of the second service.
In these alternative implementations, the service address of the offline service instance of the second service may be extracted from the first access request during the process of accessing the second service by the first service.
And 104, sending a second access request to the server indicated by the first service address so as to access the offline service instance of the second service.
In this embodiment, after obtaining the first service address, 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 on which the offline 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 authenticate the second access request. If the verification is passed, the electronic device executing the service instance access method can access the offline 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. Then, the server 201 may determine whether the first access request 202 includes the test indication information 203 of the second service. Further, in response to determining that the first access request 202 includes the test indication information 203 of the second service, the server 201 may obtain the first service address 204 of the offline service instance of 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 the offline service instance of the second service at the first service address 204.
In the related art, in order to realize the test of the offline service instance, the offline service instance can be tested separately at the server where the offline service instance is located. It should be appreciated that the offline service instance employs a separate test, even if the test passes, after deployment in the micro service architecture, the probability of failure is high because no associated tests are 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 offline 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, so as to implement 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, it may be implemented that the first service accesses the offline service instance of the second service, that is, the second service is provided through the offline service instance of the second service. Therefore, in the process that the first service accesses the second service, the test of the offline service instance of the second service is completed, namely, the correlation test of the offline service instance of the second service and the online service in the micro-service architecture is realized. The test of the correlation with the online service in the micro-service architecture can improve the test accuracy of the offline service instance of the second service, thereby reducing the probability of the failure of the offline service instance of the second service after being deployed in the micro-service architecture.
Continuing to refer to FIG. 3, a flow diagram 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:
in step 301, a first access request for a first service is received.
In this embodiment, if it is determined that the first access request includes the test indication information of the second service, the electronic device executing the service instance access method may continue to perform step 303 and step 304. If it is determined that the first access request does not include the test indication information of the second service, the electronic device executing the service instance access method may continue to perform 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, acquiring a first service address of the offline service instance of the second service.
And 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.
In this embodiment, in response to determining that the first access request does not include the test indication information of the second service, 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.
The online service instance may be a service instance already deployed in the microservice 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 microservice 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 as a target online service instance from a plurality of online service instances of the second service.
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 obtain registration information of each of a plurality of online service instances of the second service.
The registration information may be information that the online service instance is registered with a registry. The registration information may include: the service name of the service to which the online service instance belongs, the service address of the online service instance, the working state of the online service instance, and the like.
The operational state of the online service instance may include: a state accessed by other services, an idle state.
The registry may be a storage space in the microservice architecture that stores mappings between services and service addresses of service instances. For example, service a has service instance a1 and service instance a2, service instance a1 has a service address D1, and service instance a2 has a service address D2, then the registry can store the mapping relationship between service a and service addresses D1 and D2.
In some scenarios, the electronic device executing the service instance access method may obtain, in advance, registration information of each online service instance of the second service from a server in which the registry is located. At this time, the electronic device executing the service instance access method may directly obtain the registration information of each online service instance of the second service from the local.
In another scenario, the electronic device executing the service instance access method may obtain registration information of 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 obtained plurality of registration information and a preset load balancing policy.
The load balancing policy may be a policy set to adjust load balancing of a server where each online service instance is located in the micro service architecture.
In some scenarios, the electronic device executing the service instance access method may analyze the acquired multiple pieces of registration information according to a preset load balancing policy, and further 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 optional implementation manners, the target online service instance is determined through the registration information and the load balancing policy, and the target online service instance providing the second service can be determined on the premise of meeting the load balancing requirement of the server where the plurality of online service instances of the second service are located.
In this embodiment, after determining that the target online service instance is online, the electronic device executing the service instance access method may obtain a 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 under 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.
In this embodiment, after obtaining the second service address, the electronic device executing the service instance access method may send a third access request to the server indicated by the second service address, so as to access the target online service instance.
It will be appreciated that the server indicated by the second service address may be the server on which 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 authenticate 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 optional implementations, the second access request or the third access request may include the test indication information extracted from the first access request.
In these alternative implementations, the second access request or the third request includes the slave test indication information, which means that, in the process of accessing the second service by the first service, the test indication information included in the first access request is transferred to the second access request or the third access request. Thus, in the process of accessing the downstream service by the second service, the server in which 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 the embodiment shown in fig. 3. Therefore, the test of one or more offline 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 a service instance providing the second service may be determined from the multiple online service instances of the second service in the process of accessing the second service by the first service. Further, a second service address of the target online service instance is obtained, and a 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 provides the second service on the premise that the first access request does not include test indication information of the second service. Therefore, in the process that the first service accesses the second service, if the first access request contains the test indication information of the second service, the offline service instance of the second service is accessed, and if the first access request does not contain the test indication information of the second service, the online service instance of the second service target is accessed. Therefore, on the premise of not influencing the access of the first service to the second service in the micro-service architecture, the correlation test between the offline service instance of the second service and the first service is realized.
With further reference to fig. 4, as an implementation of the methods shown in the above-mentioned figures, the present disclosure provides an embodiment of a service instance access apparatus, which corresponds to the method embodiment shown in fig. 1, and which is specifically applicable to various electronic devices.

The first access unit 404 may be configured to: and sending a second access request to the server indicated by the first service address to access the offline service instance of the second service.
In this embodiment, specific processing of the receiving unit 401, the determining unit 402, the obtaining unit 403, and the first accessing unit 404 of the service instance accessing apparatus and technical effects thereof may refer to related descriptions of step 101, step 102, step 103, and step 104 in the corresponding embodiment of fig. 1, which are not described herein again.
In some alternative implementations, the test indication information may include a service address of an offline service instance of the service. The obtaining unit 403 may be further configured to: and acquiring the service address of the offline 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; and in response to determining that the service name contained in the test indication information in the first access request is the service name of the second service, determining that the test indication information of the second service is contained in the first access request.
In some alternative implementations, the service instance access device may further include a second access unit (not shown in the figure). The second access unit may be to: in response to determining that the first access request does not include test indication information for the second service, determining a target online service instance from a plurality of online service instances for the second service; acquiring a second service address of a 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.
In some optional implementations, the second access unit may be further configured to: acquiring registration information of each online service instance in a plurality of online service instances of a second service; and determining a target online service instance from a plurality of online service instances of the second service according to the acquired registration information and a preset load balancing test.

The server 501 may be the server where the first service is located. The server 503 may be a server where an offline service instance of the second service is located. The second service may be a downstream service 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 on which the upstream service of the first service resides may send a first access request to server 501 to access the first service. After 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 offline service instance of the second service. It is to be appreciated that the first service address can be a service address of an offline service instance of the second service in the server 503. Further, server 501 may send a second access request to server 503 to enable access to an offline service instance of a second service.
The server 501 and the server 503 may be hardware or software. When the server 501 and the server 503 are hardware, they may be implemented as a distributed server cluster composed of multiple servers, or implemented as a single server.

The computer readable medium may be embodied in the electronic device; or may exist separately without being assembled 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; in response to determining that the first access request contains test indication information of the second service, acquiring a first service address of an offline service instance of the second service; and sending a second access request to the server indicated by the first service address to access the offline service instance of the second service.
Computer program code for carrying out operations for the present disclosure may be written in any combination of 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 type of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet service provider).
The flowchart 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 described in the embodiments of the present disclosure may be implemented by software or hardware. Where the name of an element does not in some cases constitute a limitation of the element itself, for example, a receiving element may also be described as an element "receiving a first access request for a first service".
The functions described herein above 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: field Programmable Gate Arrays (FPGAs), Application Specific Integrated Circuits (ASICs), Application Specific Standard Products (ASSPs), systems on a chip (SOCs), Complex Programmable Logic Devices (CPLDs), 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. A 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 exemplary of the preferred embodiments of the disclosure and is illustrative of the principles of the technology employed.
