Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 4, the method for processing request information provided in this embodiment specifically includes the following steps:
s210, receiving second request information sent by a user side in the external network.
The external network may refer to a network formed by clients outside the handheld device cluster. The user terminal may refer to a terminal located outside a preset area, such as a smart phone, a computer, and the like.
Specifically, fig. 5 shows an architecture diagram for implementing distributed microservice. When any user terminal in the external network needs to request the service, the user terminal may first send the second request message to the distribution server.
S220, according to the second request information, third handheld equipment used for processing the second request information in the target handheld equipment cluster is determined, and the second request information is sent to the third handheld equipment, so that the third handheld equipment processes the second request information, and second response information is generated.
The target handheld device cluster may refer to a handheld device cluster to which the user terminal is directed. The handheld device cluster in this embodiment may be multiple, for example, logistics warehouses located at different places all correspond to one handheld device cluster. Each handheld device cluster corresponds to a cluster identifier to distinguish different handheld device clusters. For example, the location where each cluster is located may be identified as a cluster, such as a warehouse location. Each handheld device may also correspond to a device identifier, so as to distinguish different handheld devices.
Specifically, in this embodiment, each handheld device in each handheld device cluster may be registered in the distribution server in advance, so as to obtain information of each handheld device. When the second request message includes the device identifier of the handheld device for processing the second request message, the handheld device corresponding to the device identifier may be directly used as the third handheld device, and the handheld device cluster where the handheld device is located is used as the target handheld device cluster. As shown in fig. 5, the distribution server sends the second request message to the third handheld device in the target handheld device cluster. The third handheld device may process the second request message, generate a second response message, and return the second response message to the distribution server.
Exemplarily, the determining a third handheld device in the target handheld device cluster for processing the second request information according to the second request information in S220 may include: determining a target handheld device cluster from each handheld device cluster according to the cluster identifier in the second request information; and determining a third handheld device used for processing the second request information in the target handheld device cluster according to the corresponding relation between the handheld devices in the target handheld device cluster and the service types which can be provided and the request service types in the second request information.
Specifically, when the second request information includes the cluster identifier to be requested and the request service type, the handheld device cluster corresponding to the cluster identifier to be requested may be used as the target handheld device cluster. And a third handheld device in the target handheld device cluster for processing the second request information may be determined based on a similar manner for determining the second handheld device in the second embodiment. Exemplarily, the request service type is matched with a corresponding relation between the pre-stored handheld devices in the target handheld device cluster and the service types which can be provided, and the successfully matched handheld devices are taken as the handheld devices to be selected for processing the second request information in the target handheld device cluster; if only one handheld device to be selected exists, determining the handheld device to be selected as a third handheld device; and if at least two handheld devices to be selected exist, determining the handheld device to be selected with the minimum load as a third handheld device.
And S230, receiving second response information sent by the third handheld device, and sending the second response information to the user side.
Specifically, when the distribution server receives second response information sent by the third handheld device, the second response information can be sent to the user side, so that request information of the user side in the external network can be processed directly by the handheld device without processing by the cloud server, processing pressure of the cloud server is further relieved, the processing effect of micro-serving the handheld device as a server node is further improved, and the resource utilization rate of the handheld device is further improved.
It should be noted that each cluster of handheld devices corresponds to one cloud server, as shown in fig. 5. The plurality of cloud servers form a cloud server cluster. If the third handheld device for processing the second request information does not exist in the target handheld device cluster, that is, the providable service types of all the handheld devices in the target handheld device cluster are not the request service type, the distribution server may send the second request information to the target cloud server corresponding to the target server cluster for processing, so as to improve the robustness of the system.
In this embodiment, when the second service request includes a plurality of request service types, if it is determined that the handheld device in the target handheld device cluster can only process part of the request service types based on the pre-stored correspondence between the handheld device and the service types that can be provided, that is, it is determined that each handheld device in the target handheld device cluster only processes part of the request information in the second request information, then sending part of the request information to a fourth handheld device for processing part of the request information, generating third response information, and sending the remaining request information to a target cloud server in the cloud server cluster corresponding to the target handheld device cluster for processing, and generating fourth response information; the distribution server receives third response information sent by a fourth handheld device and fourth response information sent by the target cloud server, and sends the third response information and the fourth response information to the user side, so that the second request information can be split, part of request information which can be processed by the target handheld device cluster is sent to the corresponding handheld devices to be processed, the rest of request information which cannot be processed is sent to the target cloud server to be processed, and then the handheld devices in the target handheld device cluster and the target cloud server can be simultaneously utilized to be processed, and the processing pressure of the cloud server is further relieved.
According to the technical scheme, the distribution server receives second request information sent by a user side in an external network, determines a third handheld device used for processing the second request information in a target handheld device cluster, sends the second request information to the third handheld device, and processes the second request information by the third handheld device, so that the request information of the user side in the external network can be directly processed by the handheld device without processing by a cloud server, the processing pressure of the cloud server is further relieved, the processing effect of micro-serving of the handheld device as a server node is further improved, and the resource utilization rate of the handheld device is further improved.
