Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention. , not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a schematic flowchart of a file pulling method provided by this embodiment. Referring to FIG. 1 , the method is applied to a first device serving as a file pulling party. The method includes:

Step 101: establish a communication connection with the second device;

Wherein, the second device is a device that saves files to be pulled, and is any other electronic device different from the first device that has a display screen and supports web browsing, including but not limited to smart phones, tablet computers, laptop portable devices A computer, a desktop computer, a notebook computer, etc., wherein the electronic device may be an ios system or an Android system. Here, no limitation is imposed on the system of the electronic device.

It can be understood that the first device is a device that does not have the file to be pulled. As the execution body of the file pulling, it needs to establish a communication connection with the second device that saves the file to be pulled, and pull the file from the second device. Get the file to be pulled, and the file to be pulled is specifically an application file; the first device may be various electronic devices that have a display screen and support web browsing, including but not limited to desktop computers, notebook computers, tablet computers, smart phones, laptops, etc. For upper-type portable computers, etc., the electronic device may be an ios system or an Android system. Here, the system of the electronic device is not limited in any way.

Specifically, a physical connection is established between the first device and the second device, and the communication link with the second device is determined to be connected; a two-dimensional code is generated and displayed based on the identification information of the first device, so that the first device is The second device obtains the identification information of the first device based on the two-dimensional code, and sends the identification information of the second device to the first device based on the two-dimensional code; and sends the identification information of the second device to the first device based on the identification information of the second device. The second device sends a first communication connection establishment request; receives a second communication connection establishment request sent by the second device; wherein, the second communication connection establishment request is based on the second device based on the first device. The identification information is initiated; on the premise that the first communication connection establishment request and the second communication connection establishment request are both successfully set, a two-way communication connection with the second device is established.

For example, the application file named A does not exist on the computer, but the application file named A has been downloaded on the mobile phone and stored in the default storage folder of the mobile phone. In order to obtain the application file named A in the mobile terminal, the computer terminal needs to establish a communication connection with the mobile terminal, establish a physical connection between the computer terminal and the mobile terminal, and ensure that the communication link between the computer and the mobile terminal is connected. The terminal generates a two-dimensional code according to its own identification information and displays it on the display screen. The mobile terminal uses the scanning function to identify the two-dimensional code generated by the computer terminal, and obtains the identification information of the computer terminal. After determining the identification information of the computer terminal, the mobile terminal based on The two-dimensional code sends the identification information of the mobile phone to the computer; based on the identification information of the mobile, the computer sends the first communication connection establishment request to the mobile phone, the mobile phone receives the first communication connection establishment request, and sends a second communication connection establishment request based on the identification information of the computer. The communication connection establishment request is sent to the computer, and the computer receives the second communication connection establishment request sent by the mobile phone. On the premise that both the first communication connection establishment request and the second communication connection establishment request are set successfully Two-way communication connection between.

Step 102: generate access request information and send it to the second device;

Wherein, the access request is used for requesting to obtain application file description information.

It can be understood that the format of the application file is different for electronic devices of different systems. For example, the IPA file is an application package file format used by the ios operating system. The IPA file is essentially a zip compressed package containing 3 components: the app directory under the payload directory, which is the main program of the software; iTunesArtwork, which is essentially a png image without a suffix, used to display icons in iTunes; iTunesMetadata.plist, which records buyer information, selling price, etc. data. After the IPA is unpacked, it is not directly placed in the Applications directory, but in a directory composed of random codes. Its function is to only allow this software to run in a specific sandbox and not interfere with other software. Therefore, in the random code directory, in addition to the three components of IPA itself, there are three directories: Library, generally used to store data such as setting files; Documents, to store data, mostly used to save archives; tmp, temporary folder ; Another example, the APK file is an application package file format used by the Android operating system to distribute and install mobile applications and middleware. The apk file is actually a zip file, but the suffix is changed. An apk file contains: META-INF folder, which is used to store the certificate and signature information of the application; res folder is used to store some resource files that cannot be packaged into resources.arsc; AndroidManifest.xml file, which is a traditional Android manifest The file is used to describe the name, version number, required permissions, API version, components and other information of the application; the classes.dex file is the entire code logic of the application; among them, resources.arsc is the language file of the program.

It should be further noted that the application file description information is identification information describing the application file, that is, the identity information of the application file, which may be application file name information, icon information, etc., which is not specifically limited here.

Specifically, after the first device establishes a communication connection with the second device, the access request information for acquiring the description information of the application file is generated and sent to the second device.

For example, after establishing a communication connection between the computer and the mobile phone, in order to obtain the application file named A in the mobile phone, the computer generates access request information for requesting the description information of the application file A, and sends the access request information to the mobile terminal.

Step 103: Receive application file description information of the second device;

Wherein, the application file description information of the second device is used to describe the identification information of the application file installed in the second device, and the identification information of the application file is the identification information of the application file, which can be the name, icon and Identity codes, etc., are not specifically limited here.

Specifically, after the first device generates the access request information for acquiring the application file description information and sends it to the second device, the second device generates the application file description information based on the access request information sent by the first device and sends it to the first device device, the first device receives the application file description information sent by the second device.

For example, after the computer terminal generates the access request information for obtaining the description information of the application file A, and sends it to the mobile terminal, the mobile terminal generates the application file A description information based on the access request information sent by the computer terminal, that is, the name of the application file A or Its icon is sent to the computer terminal, and the computer terminal receives the description information of the application file A such as the name of the application file A or its icon sent by the mobile terminal.

Step 104: Determine a target application file based on the application file description information of the second device, and pull the target application file from the second device.

The target application file is an application file required by the user, which is an application file that does not exist in the first device but exists in the second device.

It should be further explained that the method of pulling the target application file from the second device is that the first device presents the application file description information of the second device, that is, the name, icon or identity code of the application file in the first device. On the display screen of one device, the target application file can be pulled from the second device by manually clicking, clicking with a mouse, or clicking on the description information of the target application file with a stylus pen.

Here, the execution action of pulling is to copy the application file in the second device to the first device in the form of the original version, not to pull the application file in the second device to the first device. , and the application file in the second device no longer exists.

Specifically, after the first device receives the application file description information of the second device, the application file description information is presented on the display screen of the first device, and the target application file is clicked manually, mouse click, or touch screen pen. description information, so as to pull the target application file from the second device to the first device.
