The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.

Alternatively, the specific type of the central server 10 is not limited, and may include, but is not limited to, a web server, a data server, a computer, a Mobile Internet Device (MID), and other devices having a processing function.

With reference to fig. 3, an embodiment of the present invention further provides a service invoking method applicable to the central server 10. Wherein the method steps defined by the method related flow may be implemented by the processor 14. The specific flow shown in fig. 3 will be described in detail below.

Step S110, request information of the terminal device 40 is acquired.

In this embodiment, the request information may include store ID information corresponding to the store server 30 that needs to be called. That is, when the user needs to obtain the service or information of the store (stored in the corresponding store server 30), the request information may be transmitted to the center server 10 through the terminal device 40 of the user or another person.

In consideration of the fact that the central server 10 calls the service or information of the store server 30, it is necessary to know the ip address and the port number of the store server 30 to establish a communication connection. That is, the central server 10 needs to acquire the ip address and the port number of the store server 30. However, the user or the terminal device 40 cannot obtain the ip address and the port number of the store server 30, and the ip address and the port number of one store server 30 may generally have a correspondence relationship with the ID information of the corresponding store.

Therefore, on the basis that the user or the terminal device 40 can acquire the store ID information, the correspondence relationship between the ip address, the port number, and the store ID information may be established and stored in advance, so that when the store ID information is acquired, step S130 may be performed.

Step S130, finding the ip address and the port number of the store server 30 to be called according to the store ID information.

In this embodiment, in order to avoid the problem that the ip address of the store server 30 corresponding to the store changes after the store changes, and the corresponding relationship between the store ID information and the ip address is invalid, a mechanism may be established in advance, that is, when the store server 30 determines that the ip address of the store server changes, the ip address after the store server changes may be sent to the center server 10, so that the center server 10 updates the changed ip address. That is, the ip address and the port number found by the ID information in the central server 10 are the last value sent by the store server 30, so as to ensure that the ip address and the port number obtained in step S130 have higher real-time performance and accuracy, and further avoid the problem that the service call to the store server 30 cannot be completed timely and effectively when step S150 is executed based on the ip address and the port number.

Step S150, generating a call url address according to the found ip address, port number and preset configuration information, so as to call the service of the store server 30 that needs to be called through the call url address.

In this embodiment, after the ip address and the port number of the store server 30 that needs to be called are obtained in step S130, communication can be accurately established with the store server 30 based on the ip address and the port number to call the service.

In detail, in the webservice-based system, communication between general devices is performed based on url addresses. That is, an initial url address (including fixed and variable parameters) may be pre-configured. The variable parameters may be ip addresses and port numbers, and different ip addresses and port numbers may be used as corresponding variable parameters for different store servers 30 to obtain a url address. And, the service of the store server 30 that needs to be called can be called by the url address.

Alternatively, the manner of making a call to the service of the store server 30 that needs to be called is not limited when step S150 is performed to generate a call url address. In this embodiment, referring to fig. 4, in order to avoid the problem of resource waste, step S150 may include step S151 and step S513.

And step S151, generating a calling url address according to the found ip address, the port number and preset configuration information.

Step S153, establishing a corresponding request instance through the calling url address, so as to call the service of the store server 30 that needs to be called through the request instance.

In this embodiment, a calling url address may be generated through step S151, and then step S153 is executed to establish a corresponding request instance through the calling url address, so as to call the service of the store server 30 that needs to be called through the request instance. In detail, the call url address may be used as a key to cache the established corresponding request instance.

By creating the request instance, the request instance can be directly called when service calling needs to be performed for multiple times, so that the problem that resources occupied by the processor 14 are consumed in the repeated generation process due to repeated generation of calling url addresses is avoided, and the problem that calling is not timely due to the fact that a certain time is required in the creation process is also caused.

Optionally, the manner of executing step S151 to generate the call url address is not limited, and may be set according to the actual application requirement. In this embodiment, the preset configuration information may include an initial url address, and correspondingly, in conjunction with fig. 5, step S151 may include step S151a and step S151 b.

Step S151a, acquiring the position of the ip address and the position of the port number in the initial url address.

Step S151b, replacing the parameters corresponding to the obtained location with the found ip address and port number to obtain a calling url address.

In this embodiment, the initial url address may be composed of a plurality of parts, for example, parameters that are the same for the calling url address corresponding to each store server 30 and parameters that are different for the calling url addresses corresponding to different store servers 30 may be included. The different parameters may include, among other things, the ip address and port number of the store server 30.

Therefore, when the calling url address is generated, the calling url address capable of calling the store server 30 can be obtained by executing step S151a to obtain the position of the ip address and the position of the port number in the initial url address, and then replacing the parameters of the position with the ip address and the port number acquired by executing step S130 by executing step S151 b.

Alternatively, the manner of acquiring the position through step S151a is not limited, and may be set according to actual application requirements. In this embodiment, in order to facilitate accurate and effective searching of the position of the ip address and the position of the port number in the initial url address, the initial url address has annotations of various parameters, that is, when configuring the initial url address, a corresponding annotation may be added to each parameter in the initial url address, and therefore, step S151a may include the following steps:

traversing each annotation in the initial url address to obtain annotations corresponding to the ip address and the port number; and determining the position of the ip address and the position of the port number in the initial url address according to the obtained annotation.

Through the steps of traversing all the annotations, the positions of the ip address and the port number can be accurately and effectively found, and the calling url address obtained through the replacement operation is ensured to have higher accuracy.

Further, in order to facilitate the execution of the operation of traversing the annotations, the step of obtaining the annotations may be executed first, that is, each annotation in the initial url address may be obtained first. The annotation obtaining mode is not limited, and can be set according to actual application requirements.

In this embodiment, a possible implementation is provided, and in detail, the implementation is to obtain annotations of various parameters in the initial url address through a reflection mechanism. Also, the method of performing the reflection operation may be an invoke method.

Further, it is considered that the latest ip address of the store server 30 needs to be acquired before step S130 is executed. And the acquisition mode is not limited, and can be set according to the actual application requirements.

In this embodiment, a possible implementation manner is provided, and in detail, in conjunction with fig. 6, before performing step S130, the service calling method may further include step S170 and step S190.

Step S170 monitors the message server 20 to determine whether the message server 20 has received the change information sent by the store server 30.

In the present embodiment, the change information is generated when the store server 30 changes information, and includes the current ip address, port number, and store ID information of the store server 30. The message server 20 is used for receiving and storing the change information sent by the store server 30 to form a message queue.

The message server 20 and the center server 10 are configured such that the center server 10 can monitor the message server 20, and when the message server 20 receives the change information sent by the store server 30, the change information can be obtained in time, thereby ensuring the real-time property of obtaining the ip address.

Step S190, if the message server 20 receives the change information sent by the store server 30, the change information is obtained, and a corresponding relationship is established between the ip address, the port number, and the store ID information in the change information, so that the corresponding ip address and port number can be found through the store ID information.

In this embodiment, after the change information is acquired in step S190, the correspondence relationship may be established in advance so that the changed ip address can be found by the store ID information. And, the corresponding relation can also replace the previously established corresponding relation.

For example, before the ip address is changed, the correspondence relationship between the ip address, the port number, and the store ID information may be as shown in the following table:

ip address	Port number	Store ID information
			A1	B1	C1

After the ip address is changed, the correspondence relationship between the ip address, the port number, and the store ID information may be as shown in the following table:

ip address	Port number	Store ID information
			A2	B1	C1

That is, if the central server 10 cannot acquire the changed ip address in time, the ip address found by the store ID information C1 is a1, and the service of the corresponding store server 30 is called by the call url address generated based on a1, the call cannot be completed efficiently. Therefore, the relation of a1-B1-C1 needs to be replaced by a2-B1-C1, so that the ip address found by the store ID information C1 is a2, and the call can be effectively completed when the service of the corresponding store server 30 is called by the call url address generated based on a 2.

With reference to fig. 7, an embodiment of the present invention further provides a service invocation apparatus 100 applicable to the central server 10.
