It is to be understood that, the obtaining the address of the target gateway may be that the first service end sends an address obtaining request to the first registry, and then the first registry sends the address of the target gateway to the first service end after receiving the address obtaining request. In addition, the first registry may be a database in the first cluster, and the first registry may be configured to store different data independently, for example, the first registry may store service information of the first cluster and service information of the second cluster.
in the embodiment of the application, according to the address of the target gateway, a connection can be established with the target gateway first, and then the service calling request is sent to the target gateway through the connection; the service invocation request may be for invoking a service in the second cluster.
It should be understood that, if the target gateways of the first cluster and the second cluster are pre-connected, the service invocation request can be directly sent; if the connection between the target gateways of the first cluster and the second cluster is not established in advance, the service call request can be sent to the target gateways after the connection is established according to the target gateway addresses.
According to the method for cross-cluster service calling, a first service end obtains an address of a target gateway from a first registration center; the first server side sends a service calling request to the target gateway according to the target gateway address; the first service end receives a service calling result returned by the target gateway according to the service calling request; the first server and the first registration center are located in a first cluster, the target gateway is located in a second cluster, the first registration center stores service information of the second cluster in advance, and the service information comprises an address of the target gateway. Therefore, the problem that communication between micro-services in the prior art cannot be carried out across clusters is solved by storing the service information of the second cluster in the first registration center of the first cluster in advance, then the first server of the first cluster acquires the target gateway address of the second cluster from the first registration center, then sends the service calling request to the target gateway, and receives the service calling result aiming at the service calling request, so that the services of other clusters are called as local services.

The identifier of the server may be used for the target gateway to find a corresponding server in the second cluster.
It should be understood that the service information may include the identities of all the servers in the second cluster, or may include the identities of some of the servers in the second cluster. In either case, the service information may include an identification of a target server in the second cluster, such that the target gateway finds the target server in the second cluster.

as shown in fig. 2, a first server of a first cluster prepares to call a target server of a second cluster, may first obtain an address of a target gateway from a first registry of the first cluster, and the first registry may return the address of the target gateway of the second cluster to the first server; then the first server side can initiate calling of the target server side to a target gateway of the second cluster, and after receiving the service calling request, the target gateway can perform transparent proxy on the target server side; the target server side can process the service calling request, return a service calling result to the target gateway, and finally return the service calling result corresponding to the service calling request to the first server side by the target gateway.
Therefore, the connection with the target gateway of the second cluster can be established through the target gateway address, and then the target gateway finds the target server according to the identification of the target server, so that the aim of calling the services of other clusters like calling the local service is realized.
The cross-cluster service calling method provided by the embodiment of the present application is further described in detail below with reference to an actual application scenario. Referring to fig. 2, the cross-cluster service invoking method provided in the embodiment of the present application may specifically include the following steps:
step 210, the first service end obtains the address of the target gateway and the identification of the target service end from the first registration center;
step 220, the first server sends a service calling request to the target gateway according to the target gateway address, wherein the service calling request carries an identifier of the target server;
step 230, the target gateway sends the service call request to the target server according to the identifier of the target server;
step 240, the target server obtains a service calling result according to the service calling request, and returns the service calling result to the target gateway;
step 250, after receiving the service calling result, the target gateway sends the service calling result to the first service end.
According to the cross-cluster service calling method provided by the embodiment of the application, the target gateway address of the second cluster and the identification of the service end in the second cluster are stored in the first registration center of the first cluster in advance, then the first service end obtains the target gateway address of the second cluster from the first registration center, then the first service end establishes connection with the target gateway of the second cluster, then the service calling request is sent to the target gateway through the connection, and the service calling result aiming at the service calling request is received, so that the local service is called to call the services of other clusters, and the problem that cross-cluster communication cannot be carried out between micro-services in the prior art is solved.
Optionally, in an embodiment of the present application, before step 110, the method for invoking a cross-cluster service provided in the embodiment of the present application may further include: the first synchronization component (pilot component) sends a first synchronization request to the second agent component (agent component); the second agent component sends first synchronization information to the first synchronization component according to the first synchronization request, wherein the first synchronization information comprises service information of the second cluster; and the first synchronization component receives the first synchronization information sent by the second agent component and sends the first synchronization information to the first registration center.
Wherein the first synchronization component may be located in the first cluster and the second proxy component may be located in the second cluster. The first synchronization component may be configured to synchronize service information of the second cluster to the first registry of the first cluster; the second proxy component may be configured to be responsible for collecting service information of the second cluster, and provide convenience of service synchronization to the first synchronization component of the first cluster.
In this manner, the service information of the second cluster may be synchronized in real-time to the first registry of the first cluster by the first synchronization component and the second proxy component.

it is to be appreciated that the first synchronization component can establish a synchronization flow with the second proxy component to synchronize service information of the second cluster in an instance in which the second proxy component grants the first synchronization request. The synchronous stream (stream) can continuously push data, and is suitable for transmitting some large data or for long-time data interaction such as a server and a client. For example, a client may subscribe to a server for data, and the server may continuously push data to the client using a synchronous stream.
Step 330, the second agent sends first synchronization information to the first synchronization component according to the first synchronization request, wherein the first synchronization information includes service information of the second cluster;
in an embodiment of the application, the second proxy component may send the first synchronization information to the first synchronization component via the synchronization stream.
Step 340, the first synchronization component receives the first synchronization information sent by the second agent component, and sends the first synchronization information to the first registry.
It is to be understood that the sending of the first synchronization information by the first synchronization component to the first registry may correspond to storing the service information of the second cluster in the local database of the first cluster in advance, so that the first server may call the service of the second cluster as a local service subsequently.
According to the cross-cluster service calling method provided by the embodiment of the application, the service information of the second cluster can be synchronized to the first registration center of the first cluster in real time through the first synchronization component and the second proxy component, so that the follow-up first service end can call the service end of the second cluster as the service end of the first cluster is called.
Optionally, in an embodiment of the present application, the first registry further stores service information of the first cluster; the method for calling the cross-cluster service provided by the embodiment of the application can further comprise the following steps: the second synchronization component (pilot component) sends a second synchronization request to the first agent component (agent component); and the first proxy component sends second synchronization information to the second synchronization component according to the second synchronization request, wherein the second synchronization information comprises service information of the first cluster.
Wherein the second synchronization component can be located in the second cluster and the first proxy component can be located in the first cluster. The second synchronization component may be configured to synchronize service information of the first cluster to the second registry of the second cluster; the first proxy component may be configured to be responsible for collecting service information of the first cluster and provide service synchronization convenience for the second synchronization component of the second cluster.
In this way, the service information of the first cluster can be synchronized in real time to the second registry of the second cluster by the second synchronization component and the first proxy component.
In the following, in combination with an actual application scenario, service synchronization and stepping in the cross-cluster service calling method provided by the embodiment of the present application are further described in detail. Referring to fig. 4, the service synchronization in the cross-cluster service invocation method provided in the embodiment of the present application may further specifically include the following steps:
step 410, the first agent component obtains service information of the first cluster from a first registry of the first cluster;
the first registry may further store service information of the first cluster in advance, where the service information may include an address of a target gateway of the first cluster and an identifier of a server in the first cluster.
Step 420, the second synchronization component sends a second synchronization request to the first proxy component;
it is to be appreciated that the second synchronization component can establish a synchronization flow with the first proxy component to synchronize the service information of the first cluster in an instance in which the first proxy component grants the second synchronization request.
Step 430, the first proxy component sends second synchronization information to the second synchronization component according to the second synchronization request, where the second synchronization information includes service information of the first cluster;
in an embodiment of the application, the first proxy component may send the second synchronization information to the second synchronization component through the synchronization stream.
Step 440, the second synchronization component receives the second synchronization information sent by the first agent component, and sends the second synchronization information to the second registry.
According to the method for cross-cluster service calling, the service information of the first cluster can be synchronized to the second registration center of the second cluster in real time through the second synchronization component and the first proxy component, and therefore the purpose that a target server side of the second cluster subsequently calls the service of the first cluster like calling the local service of the second cluster is achieved.
