According to an embodiment of the present application, there is provided an information push method.
Fig. 1 is a flowchart of an information push method provided according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, receiving a user request through a host, and analyzing request information of the user request, wherein the request information includes a request object, attribute information of the request object, and a preset number of the request objects.
Specifically, the host may be a computer that receives a user request from a certain central computer room (single computer room) in which the microservice server is located. When a user sends a request, the user needs to receive the request through the computer device corresponding to the user, and perform data interaction and data summarization with the servers of the microservices in other machine rooms through the computer device to obtain a request result, so that the request result is fed back to a user side through the computer device.
After receiving the user request, the user request needs to be analyzed, so as to obtain the request information of the user, wherein after analyzing the request information, the request object requested this time, the attribute information of the request object, and the preset number of the request objects can be obtained.
For example, the request object in the request information may be restaurant information, and the attribute information may include: distance information, price information and restaurant types, and the preset number may be 20, that is, 20 restaurants need to be pushed.
Step S102, respectively determining a server for querying the request object under each attribute information, obtaining a plurality of servers, and sending the request object, the preset number and each attribute information to the corresponding server.
Specifically, each microserver can only solve the problem corresponding to the microserver because the microserver is based on a small functional block dedicated to a single responsibility for a function and combines a complex large application program in a modular manner. For example, the server of the a micro service can only obtain 20 restaurants with a short distance, and the server of the B micro service can only obtain 20 restaurants with a low price.
Therefore, after determining the attribute information, the request object, the corresponding attribute information and the preset number can be sent to each micro server, so that the corresponding candidate result can be obtained from the server of the micro server.
Step S103, receiving candidate object sets fed back by the servers based on the attribute information, where each candidate object set includes a preset number of objects.
Specifically, when each server obtains a request result corresponding to the request information, that is, a candidate object set, the host may receive the candidate object set returned by each server, so that the request result information finally fed back to the user side may be determined from a plurality of candidate object sets.
And step S104, acquiring the objects in all the candidate object sets through the host to obtain a plurality of candidate objects, screening a preset number of objects from the plurality of candidate objects to obtain target objects, and sending the preset number of target objects to a user.
Specifically, the host obtains objects in the multiple candidate object sets to obtain multiple candidate objects, and further performs screening according to the weight of each candidate object or the number of attribute information included in the candidate object, so as to obtain a target object from the multiple candidate objects, and sends the target object as a return result of the request information to the user side.
For example, if the candidate object set returned by the server a includes the candidate object a, the candidate object B, and the candidate object C, and the candidate object set returned by the server B includes the candidate object C, the candidate object D, and the candidate object E, the candidate object C may be sent to the user side as the target object.
The information pushing method provided by the embodiment of the application receives a user request through a host and analyzes request information of the user request, wherein the request information comprises a request object, attribute information of the request object and a preset number of the request objects; respectively determining a server for querying the request object under each attribute information to obtain a plurality of servers, and sending the request object, the preset number and each attribute information to the corresponding server; receiving candidate object sets fed back by each server based on the attribute information, wherein each candidate object set comprises a preset number of objects; the method comprises the steps of obtaining objects in all candidate object sets through a host to obtain a plurality of candidate objects, screening a preset number of objects from the candidate objects to obtain target objects, and sending the preset number of target objects to a user. The problem that software service with single function in the related technology can not provide stable service in a single machine room mode is solved. By receiving the candidate objects returned by each server, selecting the most suitable candidate object from the candidate objects as the request result requested by the user, and acquiring the candidate objects from other servers under the condition that part of hosts or servers are abnormal, the effect of stably feeding back the request result to the user under the condition that part of micro-services are abnormal is achieved.
In order to successfully acquire a candidate object corresponding to each attribute information from a server, optionally, in the information pushing method provided in the embodiment of the present application, a storage system of each server includes an internal cache, an external cache, and a distributed storage system, and receiving a candidate object set fed back by each server based on the attribute information includes: under the condition that a candidate object set under corresponding attribute information exists in an internal cache of a server, receiving a candidate object set acquired by the server from the internal cache; under the condition that the candidate object set does not exist in the internal cache and the candidate object set exists in the external cache of the server, receiving the candidate object set acquired by the server from the external cache; under the condition that the candidate object set does not exist in the internal cache and the external cache and the candidate object set exists in the distributed storage system of the server, receiving the candidate object set acquired by the server from the distributed storage system; and under the condition that no candidate object set exists in the internal cache, the external cache and the distributed storage system, receiving abnormal information returned by the server, wherein the abnormal information represents that no candidate object set exists in the storage system of the server.
Specifically, the storage system corresponding to each server may use a three-layer cache structure for data storage, where the first layer may be a local cache local to the server, that is, an internal cache, and the second layer may be an external cache, for example, a non-relational key-Value cache system, for example: mongoDB, the third tier may be a distributed storage system for caching data over a long period of time through the distributed system. After the server receives the request object, the preset number and the attribute information, it may obtain a corresponding candidate object in the internal cache according to the request object, the preset number and the attribute information, and prove that, in a case that the candidate object cannot be obtained in the internal cache, the storage information in the internal cache has been deleted overtime, so that it is necessary to perform query on the candidate object in the external cache of the second layer.
Further, when the request objects, the preset number and the candidate objects corresponding to the attribute information cannot be acquired in all the three-layer caches, it is indicated that no corresponding candidate object exists in the caches of the server, or the server is abnormal and cannot acquire the candidate object, at this time, the server sends abnormal information to the host to indicate that the server cannot acquire the corresponding candidate object.
It should be noted that, since other servers may also be damaged, and other abnormalities may occur, after the host sends out the information, the server may not receive the information at all due to the damage, and similarly, the result may not be returned. Therefore, the host computer can also set a timeout time, and when the candidate object returned by the server is not received after the timeout time is exceeded, the server is determined to be in a damaged state, and at this time, the server is considered to return the abnormal information.
In order to still return information to the user when the server is abnormal or the server cannot obtain the candidate object, optionally, in the information pushing method provided in the embodiment of the present application, after sending each piece of attribute information to the corresponding server, the method further includes: determining attribute information corresponding to a server which feeds back abnormal information under the condition that a host receives the abnormal information fed back by any server to obtain target attribute information, wherein the abnormal information represents that a candidate object set under the corresponding attribute information does not exist in a storage system of the server; sending the target attribute information to other servers, wherein the other servers are servers except the server feeding back the abnormal information; and acquiring candidate objects under the target attribute information of a preset number from other servers.
Specifically, when a certain server returns abnormal information, the server is abnormal and cannot feed back a corresponding candidate object, and in order to avoid that the candidate object corresponding to the request information cannot be returned to the user due to the fact that part of component content is lacked because part of the servers do not feed back, when the certain server is abnormal, data to be acquired in the abnormal server needs to be acquired in the rest servers, so that the candidate object can be acquired from each server.
For example, after the a attribute information is sent to the a server, the candidate object set returned by the a server is not received when the timeout time is reached, and at this time, it is determined that the a server is abnormal, the a attribute information is sent to the remaining servers, and since the request objects and the preset number have been acquired in the remaining servers, the candidate objects corresponding to the a attribute information may also be returned to the host when the candidate objects corresponding to the a attribute information exist in the remaining servers. For example, if the preset number is 20, 10 candidate objects corresponding to the a attribute information exist in the B server, and 10 candidate objects corresponding to the a attribute information exist in the C server, the 20 candidate objects may be determined as 20 candidate objects corresponding to the a attribute information, and the 20 candidate objects are sent to the host through the B server and the C server, so that the host can obtain a candidate object set corresponding to the a attribute information.
In order to still return information to the user when the server is abnormal or the server cannot acquire the candidate object, optionally, in the information push method provided in the embodiment of the present application, after sending each piece of attribute information to the corresponding server, the method further includes: under the condition that the host receives abnormal information fed back by any server, acquiring a server with the highest similarity with the server fed back the abnormal information from other servers to obtain a target server, wherein the abnormal information represents that a candidate object set under the corresponding attribute information does not exist in a storage system of the server, and the other servers are servers except the server fed back the abnormal information; and acquiring a preset number of candidate objects from the target server.
Specifically, when a certain server returns abnormal information, the server is abnormal and cannot feed back a corresponding candidate object, and in order to avoid that a candidate object corresponding to the request information cannot be returned to the user due to the fact that part of component contents are lacked because part of the components are not fed back, the server most similar to the abnormal server can be obtained when the certain server is abnormal, and a corresponding candidate object set is obtained from the similar server.
For example, if the attribute information of the server a is japanese restaurant, the attribute information of the server B is near, and the attribute information of the server C is cheap, if the server a is abnormal, a server closest to the attribute information of the server a may be obtained from any other server, and if the attribute information of the server D is korean restaurant, for example, a predetermined number of candidate objects may be specified in the server D, and the candidate objects may be sent to the host computer.
In order to still return information to the user when the server is abnormal or the server cannot obtain the candidate object, optionally, in the information pushing method provided in the embodiment of the present application, after receiving a candidate object set fed back by each server based on the attribute information, the method further includes: under the condition that the host receives the abnormal information fed back by the server, counting the quantity of the abnormal information, and judging whether the quantity of the abnormal information is equal to the quantity of the attribute information or not; and under the condition that the quantity of the abnormal information is equal to that of the attribute information, sending the preset object associated with the request information to the user through the host.
In particular, in an extreme case, it may happen that all servers associated with the requested information are all abnormal. At this time, since blank page or blank information cannot be fed back to the user, the preset object associated with the request information and stored in the host cache can be directly acquired and sent to the user, thereby ensuring that the user side does not receive the blank page information.
For example, the request information may be for applying for acquiring a data, where the data a needs to be composed of three parts, i.e., needs to be acquired from three servers, i.e., B/C/D, but when all three servers are abnormal, a preset object with the strongest association degree with the data a is acquired in a cache of the host, and the preset object is directly sent to the user, so that the use experience of the user is ensured.
Optionally, in the information pushing method provided in the embodiment of the present application, the screening a preset number of objects from a plurality of candidate objects to obtain a target object includes: determining attribute information corresponding to each candidate object to obtain multiple groups of attribute information; calculating the target weight of the corresponding candidate object according to the weight of each attribute information in each group of attribute information to obtain a plurality of target weights; and selecting a preset number of objects from the candidate objects according to the sequence of the target weight values from large to small to obtain the target object.
It should be noted that the weight of the attribute information represents the importance degree of the attribute information, for example, the weight of the a attribute information is 10, the weight of the B attribute information is 20, which indicates that when the request result of the request information is fed back, the importance degree of the B attribute information is higher than that of the a attribute information, for example, an a candidate object exists in the candidate object set corresponding to the a attribute information and simultaneously exists in the candidate object set corresponding to the C attribute information, and a B candidate object exists in the candidate object set corresponding to the B attribute information and simultaneously exists in the candidate object set corresponding to the C attribute information, because the weight of the a attribute information is smaller than the weight of the B attribute information, the candidate object recommended to the user is the B candidate object.
Specifically, after obtaining a plurality of candidate objects, attribute information corresponding to each candidate object may be determined, and a target weight of each candidate object may be calculated according to the weight of each attribute information, so that the plurality of candidate objects are sorted according to the target weight of the candidate object, and a preset number of candidate objects ranked before are sent to the user as the target objects, so that the user may obtain an optimal request result.
For example, if the weight of the a attribute information is 1, the weight of the B attribute information is 2, the weight of the C attribute information is 3, the weight of the D attribute information is 4, the a candidate object exists in the candidate object set corresponding to the a attribute information, and exists in the candidate object set corresponding to the C attribute information at the same time, the target weight of the a candidate object may be 1+3=4, the B candidate object exists in the candidate object set corresponding to the B attribute information, and exists in the candidate object set corresponding to the D attribute information at the same time, the target weight of the B candidate object may be 2+4=6, the target weight of the a candidate object is smaller than the target weight of the B candidate object, and the B candidate object may be sent to the user under the condition that the preset number is 1, so that the user obtains a more suitable feedback result.
In order to enable faster feedback of a request result, optionally, in the information pushing method provided in this embodiment of the application, after receiving a user request through the host and parsing request information of the user request, the method further includes: judging whether a history target object corresponding to the user request exists in the cache of the host; and under the condition that the history target object exists in the cache of the host, sending the history target object to the user.
Specifically, after receiving a user request, whether a history record exists or not may be searched in a cache of the host, that is, whether the user request is a re-request or not, and if the user request is a re-request, a history target object corresponding to the history record stored in the host may be directly returned to the user, so that an effect of quickly feeding back a request result is achieved.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
The embodiment of the present application further provides an information pushing apparatus, and it should be noted that the information pushing apparatus in the embodiment of the present application may be used to execute the method for pushing information provided in the embodiment of the present application. The following describes an information pushing apparatus provided in an embodiment of the present application.
Fig. 2 is a schematic diagram of an information pushing apparatus provided according to an embodiment of the present application. As shown in fig. 2, the apparatus includes: the device comprises an analysis unit 21, a first determination unit 22, a receiving unit 23 and a first acquisition unit 24.
Specifically, the parsing unit 21 is configured to receive a user request through the host, and parse request information of the user request, where the request information includes a request object, attribute information of the request object, and a preset number of the request objects.
The first determining unit 22 is configured to determine servers used for querying the request object under each attribute information, obtain a plurality of servers, and send the request object, the preset number, and each attribute information to the corresponding server.
The receiving unit 23 is configured to receive candidate object sets fed back by the servers based on the attribute information, where each candidate object set includes a preset number of objects.
The first obtaining unit 24 is configured to obtain, by the host, objects in all the candidate object sets to obtain a plurality of candidate objects, screen a preset number of objects from the plurality of candidate objects to obtain target objects, and send the preset number of target objects to the user.
The information pushing apparatus provided in the embodiment of the application receives a user request through the host by using the parsing unit 21, and parses request information of the user request, where the request information includes a request object, attribute information of the request object, and a preset number of the request objects; the first determining unit 22 determines a server for querying the request object under each attribute information, obtains a plurality of servers, and sends the request object, a preset number and each attribute information to the corresponding server; the receiving unit 23 receives candidate object sets fed back by the servers based on the attribute information, wherein each candidate object set contains a preset number of objects; the first obtaining unit 24 obtains objects in all candidate object sets through the host to obtain a plurality of candidate objects, screens a preset number of objects from the plurality of candidate objects to obtain target objects, and sends the preset number of target objects to the user.
