Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of an application scenario of a data information obtaining method according to an embodiment of the present invention, as shown in fig. 1, the scenario includes a first terminal 1, a second terminal 2, a third terminal 3, and a server 4, where the first terminal 1, the second terminal 2, and the third terminal 3 may not only directly communicate with the server 4, but also communicate with each other, each terminal may include multiple apps, and the first terminal 1, the second terminal 2, and the third terminal 3 may be terminal devices such as a mobile phone, a computer, a game console, and the like. The first terminal 1, the second terminal 2 and the third terminal 3 can communicate with each other, and the first terminal 1, the second terminal 2 and the third terminal 3 can communicate with the server 4.
It should be noted that fig. 1 is only an exemplary scenario and is not intended to limit the present invention.
In the prior art, when the first terminal 1, the second terminal 2, and the third terminal 3 need to acquire data information, they all need to send request messages to the server 4, and the server 4 respectively returns corresponding data information to each terminal after performing service logic processing according to the request messages. If the first terminal 1, the second terminal 2, and the third terminal 3 simultaneously send the request message to the server 4, and the server 4 has limited capability and cannot process the three requests simultaneously, the request message of the first terminal 1 may be processed first, and then the request messages of the second terminal 2 and the third terminal 3 are processed in sequence, so that the data information returned by the server 4 to the second terminal 2 and the third terminal 3 may have a large delay, and the user may not see the requested data information for a long time, which results in poor user experience.
In the embodiment of the invention, the apps in the first terminal 1, the second terminal 2 and the third terminal 3 can release services when being started, and the App in each terminal can store the services released by the apps of other devices. For example, the first terminal 1 may store services issued by apps in the second terminal 2 and the third terminal 3, and establish a service list. When the first terminal 1 needs to acquire data information, a service is determined from the service list according to the Key value, the determined service is associated with the second terminal 2, namely the determined service is issued by the second terminal 2, the first terminal 1 establishes a link with the second terminal 2, and acquires the data information from the cache of the second terminal 2 according to the Key value, the first terminal 1 can directly acquire the data information from the cache in the second terminal 2, and the situation that a request message is directly sent to the server 4 to acquire the data information is avoided, so that the speed of responding to the data information is improved, and the first terminal can quickly display the required data information to a user.
Fig. 2 is a flowchart of a method for acquiring data information according to an embodiment of the present invention. The execution main body of the method is a terminal, wherein the terminal can be a mobile phone, a computer, an ipad, a game machine, a smart television and the like, a plurality of apps are installed on the terminal, and the terminal executes the following steps through the installed apps, as shown in fig. 2, the method of the embodiment may include:
In this embodiment, after the terminal is started, when the first service needs to be initiated, other terminals capable of providing the first service around the terminal may be queried according to the location of the terminal. For example, it may be detected through zero configuration networking (Bonjour) whether other terminals around may provide the first service.
In this embodiment, if another terminal capable of providing the first service is found, the terminal establishes a connection with the found terminal capable of providing the first service, and initiates a request to the found terminal to acquire data information for initiating the first service. For example, when a first terminal needs to publish a first service, it is queried whether other terminals around the first terminal can provide the first service, and if it is queried that a second terminal can provide the first service, the first terminal establishes a connection with the second terminal and sends a request message to the second terminal, where the request message is used to obtain data information needed for publishing the first service from the second terminal.
For example, the first terminal sends a connection establishment request to the second terminal, and the second terminal returns a request response to the first terminal after receiving the connection establishment request, so that the connection establishment is successful. Other ways may be used, and the present invention is not limited thereto.
And 103, if the data information exists in the searched cache of the terminal, acquiring the data information from the searched cache of the terminal through a Key value, wherein the Key value is the full path information of the App request in the terminal.
The full path information of the App request may be a website, an address, etc., for example, the full path information of the first App request may be a Uniform Resource Locator (URL).
In this embodiment, the terminal that needs to issue the first service uses the full path information of the App request as a Key value, queries the data in the cache of the searched terminal, and if the data information needed for sending the first service is queried, acquires the data information from the cache of the searched terminal, and then issues the first service.
According to the method for acquiring the data information, when a terminal needs to initiate a first service, according to the position of the terminal, other terminals capable of providing the first service are inquired, the terminal is connected with the inquired terminal, the data information for initiating the first service is requested from the inquired terminal, if the data information exists in the cache of the inquired terminal, the data information is acquired from the cache of the inquired terminal through a Key value, the terminal can acquire the data information for issuing the first service from other surrounding terminals, compared with the data information acquired from a server, the time for responding to the data information is reduced, the transmission speed of the data information is improved, the terminal can quickly show the data information to a user, and the user experience is improved.

In this embodiment, the service list is a list pre-established by the terminal device, and the service list is used for storing services issued by other terminals, where the services issued by a plurality of terminals may be the same type of service or different types of services. When other terminals issue services, the terminals store the services issued by the other terminals in the service list.
Further, determining a first service corresponding to the Key value includes: and the terminal polls all services in the service list by taking the full path information as a Key value according to the full path information requested by the App, and determines a first service corresponding to the Key value.
In this embodiment, when an App in a terminal is started, first, full path information of an App request initiated by a user through the terminal is obtained, the full path information is used as a Key value, all services in a service list are polled, and a first service corresponding to the Key value is determined.
