As shown in fig. 2, in an embodiment, a method for fetching an air interface data packet is provided, which is applicable to the electronic device described above, and the method may include the following steps:

step 210, outputting a first display interface including a wireless hotspot list, wherein the wireless hotspot list includes at least one wireless hotspot.

The first display interface may refer to an interface for displaying a wireless hotspot capable of capturing an air interface data packet, where the wireless hotspot refers to an Access Point capable of providing a wireless network Access service, and the wireless hotspot may also be referred to as an Access Point (AP). In some embodiments, a gripping tool for gripping an air interface data packet may be integrated in an operating system of the electronic device, and the gripping tool may be integrated in a system of the electronic device by means of an APP (Application program). As a specific implementation manner, the electronic device may provide an application icon corresponding to the grappling tool on the desktop, and the user may access and open the grappling tool by triggering the application icon to enter an application interface of the grappling tool.

As another specific implementation, the electronic device may not provide an application icon corresponding to the grappling tool on the desktop, and the user may input an opening instruction for opening the grappling tool in the electronic device, and when the electronic device receives the opening instruction, the electronic device may access and open the grappling tool installed on the electronic device and enter an application interface of the grappling tool. Alternatively, the opening instruction may be a simple preset instruction, for example, an instruction such as #1# is input through a dial of the electronic device, and the grasping tool may be accessed. Upon entering an application interface of the crawling tool, a first display interface may be displayed on the screen.

In some embodiments, when the grasping tool is turned on, the electronic device may scan surrounding wireless hotspots and generate a wireless hotspot list according to each scanned wireless hotspot. Further, the Wireless network scanning interface may be invoked to scan surrounding Wireless hotspots, such as Wireless hotspots within a preset range (e.g., within 30 meters, within 50 meters, etc.), wherein the Wireless network may include, but is not limited to, a WiFi (Wireless Fidelity) network, etc. Optionally, the manner in which the electronic device scans for the wireless hotspot may be active scanning or passive scanning. The active scanning refers to that the electronic device sends a Probe Request (Probe Request) data frame on each channel in an active manner, and scans surrounding wireless hotspots according to Probe Response (Probe Response) frames returned by each wireless hotspot. The passive scanning means that the electronic device switches and receives data packets broadcast by each wireless hotspot, such as Beacon (Beacon) frames, on each channel without transmitting any signal, so as to scan the surrounding wireless hotspots. By means of the passive scanning mode, power consumption of the electronic equipment in the process of scanning the wireless hotspot can be saved.

In some embodiments, a wireless hotspot list may be included in the first display interface, and the wireless hotspot list may include hotspot names of one or more (a plurality refers to two or more) scanned wireless hotspots. FIG. 3A is a diagram illustrating a first display interface in one embodiment. After the electronic device starts the capture tool, a first display interface 310 may be displayed, the first display interface 310 may include a wireless hotspot list 302, the wireless hotspot list 302 may include scanned WiFi hotspots, for example, fig. 3A may include 5 scanned WiFi hotspots, and names of the WiFi hotspots may be displayed in the wireless hotspot list 302. Further, a selection prompt message 304 may also be displayed in the first display interface 310, where the selection prompt message 304 may be used to prompt the user to select a wireless hotspot where an air interface data packet needs to be captured, for example, the selection prompt message 304 in fig. 3A is "please select a WiFi hotspot where you need to capture an air interface packet", and the user may accurately know how to perform an operation based on the selection prompt message 304.

Step 220, responding to the hotspot selection operation aiming at the wireless hotspot list, and acquiring the hotspot information of the selected target wireless hotspot.

The electronic equipment can respond to the hotspot selection operation aiming at the wireless hotspot list and determine a target wireless hotspot selected by a user, wherein the target wireless hotspot is a wireless hotspot needing to capture an air interface data packet. Optionally, the hotspot selection operation may include, but is not limited to, a touch operation (e.g., clicking a wireless hotspot whose null data packet needs to be captured), a voice control operation (e.g., acquiring a name of the wireless hotspot whose null data packet needs to be captured and spoken by a user), a line of sight selection operation (e.g., acquiring an eye image of the user through a camera, and analyzing a position of a focus on a screen according to the eye image, so as to determine a target wireless hotspot whose focus needs to be selected), and the like, and may also be an air-separating gesture, which is not limited herein.

In some embodiments, the electronic device may obtain a hotspot name of the selected target wireless hotspot in response to a hotspot selection operation for the wireless hotspot list, and determine whether the hotspot name satisfies a preset naming rule. When the captured air interface data packet is analyzed, the air interface data packet with the hotspot name comprising the Chinese character cannot be analyzed, so that the selected hotspot name of the target wireless hotspot needs to meet the naming rule without the Chinese character. The method comprises the steps of carrying out character recognition on the acquired hotspot name of the target wireless hotspot, judging whether the hotspot name comprises Chinese characters or not, if so, displaying prompt information for modifying the name on a first display interface, wherein the prompt information can be used for prompting a user to modify the hotspot name of the target wireless hotspot.

As shown in fig. 3B, after the user selects a wireless hotspot to be captured of an air interface data packet in the wireless hotspot list 302, if it is detected that the hotspot name of the selected target wireless hotspot contains a chinese character, a prompt message 306 for modifying the name may be displayed in the first display interface 310. For example, "only grabbing WiFi hotspot air interface packages with WiFi names of 'english' and 'number' can be supported, please modify the WiFi name" can be displayed in the prompt message 306 for modifying the name. The user can clearly know the operation required to be performed by modifying the prompt message 306 of the name, thereby playing an effective guiding role. It should be understood that the above prompt information for selecting and modifying the name may also be output by voice, and is not limited to the display on the first display interface.

The hotspot information of the target wireless hotspot may include, but is not limited to, a hotspot identification, a frequency band, a channel, a bandwidth, etc. of the target wireless hotspot. The hotspot identification may include a hotspot name, a Service Set Identifier (SSID), and the like. The frequency band may refer to an operating frequency range of the wireless hotspot, and optionally, the frequency band may include 2.4GHz (gigahertz), 5GHz, and the like. The channel refers to a data signal transmission channel using a wireless signal as a transmission medium, channels included in different frequency bands may be different, and one frequency band may include one or more channels. Bandwidth refers to the amount of data transmitted over a wireless link per unit time and may be used to represent the data transmission capability of the wireless communication link.

In some embodiments, the hotspot information for the target wireless hotspot may be hotspot information obtained when scanning for the target wireless hotspot. When the electronic equipment scans each surrounding wireless hotspot, the hotspot information of each wireless hotspot can be obtained according to the broadcast data packet sent by each wireless hotspot and stored. After the target wireless hotspot selected by the user is determined, hotspot information acquired when the target wireless hotspot is scanned can be acquired, and an air interface data packet of the target wireless hotspot is captured according to the hotspot information.

In some embodiments, the hotspot information of the target wireless hotspot may also be hotspot information obtained when the electronic device is connected to the target wireless hotspot. After the electronic device acquires the target wireless hotspot selected by the user, the electronic device can call a bottom wireless communication module (such as a WiFi module) to establish wireless communication connection with the target wireless hotspot, and acquire hotspot information of the target wireless hotspot through the established wireless communication connection, and can capture an air interface data packet of the target wireless hotspot according to the hotspot information after the communication connection with the target wireless hotspot is disconnected.

And step 230, capturing an air interface data packet of the target wireless hotspot according to the hotspot information.

In some embodiments, after acquiring the hotspot information of the target wireless hotspot, the electronic device may determine a target channel that needs to be subjected to packet capturing, may monitor an air interface data packet transmitted by the target wireless hotspot in the target channel, and capture the monitored air interface data packet. After the air interface data packet is captured, the air interface data packet can be analyzed according to the hotspot identification of the target wireless hotspot, so that the analyzed air interface packet data is obtained. In some embodiments, if the target wireless hotspot is an encryption hotspot, the password of the target wireless hotspot may be acquired, and the captured air interface data packet is analyzed according to the SSID and the password of the target wireless hotspot to obtain the analyzed air interface packet data. Optionally, the captured air interface data packet may also be filtered according to a terminal identifier of the test terminal, so as to obtain an air interface data packet transmitted between the test terminal and the target endless hotspot, where the terminal identifier may include, but is not limited to, any one of a Media Access Control (MAC) address, a terminal number, and the like of the test terminal.

In some embodiments, if the target wireless hotspot is an encrypted hotspot, the user may first be prompted to enter a password for the target wireless hotspot. Before establishing communication connection with a target wireless hotspot through a wireless communication module, when the target wireless hotspot is an encrypted hotspot, the electronic device can display first prompt information on a first display interface, wherein the first prompt information can be used for prompting to input a password of the target wireless hotspot. The electronic equipment can verify the input password after acquiring the input password, and can control the wireless communication module to establish communication connection with the target wireless hotspot by adopting the input password, if the connection is successful, the password is verified to be correct, and if the connection is failed, the password is verified to be wrong.

As shown in fig. 5B, after the user selects a wireless hotspot where an air interface data packet needs to be captured in the wireless hotspot list 302, if the selected target wireless hotspot is an encrypted hotspot, a first prompt message 504 may be displayed in the first display interface 310, where the first prompt message 504 may be used to prompt the user to input a password of the selected target wireless hotspot. When it is detected that the user triggers the confirmation key, the password input by the user in the first prompt message 504 may be acquired and verified.

In some embodiments, if the input password is verified to be incorrect, the wireless communication module cannot connect with the target wireless hotspot by adopting the input password, the user can be prompted that the password is incorrect, the first prompting message is displayed again, and the user can input the password of the target wireless hotspot again.

In some embodiments, when the electronic device receives the instruction to start grabbing, second prompt information may be displayed on the second display interface, where the second prompt information is used to prompt the test terminal to disconnect the communication connection with the target wireless hotspot and to reestablish the communication connection with the target wireless hotspot again.

And 716, capturing an air interface data packet transmitted between the test terminal and the target wireless hotspot according to the complete hotspot information when the command of starting to capture is received.

The descriptions of steps 702 to 716 may refer to the descriptions of the above embodiments, and are not repeated herein, it should be noted that step 708 may be performed before step 704, or may be performed after step 706, and the execution sequence is not limited herein.

In some embodiments, when receiving the start grab instruction, the electronic device may obtain the current remaining memory, which may refer to the current available memory, and optionally may obtain the current remaining memory by calling an available memory obtaining interface, such as getMemoryInfo (). Whether the current residual memory is smaller than a first threshold value or not can be judged, and if the current residual memory is smaller than the first threshold value, the current residual memory is less and is not suitable for capturing an air interface data packet. If the current remaining memory is smaller than the first threshold, a third prompt message may be output, where the third prompt message may be displayed on the second display interface, or may be output by voice or other means, for example, the third prompt message that "the current memory is insufficient, please release a part of the memory and then start to capture" may be output by voice, and the prompt mode of the third prompt message is not limited herein. And after the user receives the third prompt message, the memory of the electronic equipment can be released by closing the processes which are not required to be used. In some embodiments, if the current remaining memory is smaller than the first threshold, the electronic device may also directly kill the process that is currently running in the background and has a lower priority, thereby releasing the memory.

When the electronic device releases the memory, the current residual memory can be detected in real time, and when the current residual memory is not smaller than the first threshold, the air interface data packet of the target wireless hotspot can be captured according to the hotspot information of the target wireless hotspot. The captured air interface data packet can be stored, after the air interface data packet is stored, whether the remaining memory is smaller than a second threshold value or not can be judged, and if the remaining memory is smaller than the second threshold value, the capturing of the air interface data packet can be stopped. Optionally, the first threshold and the second threshold may be set according to actual requirements, for example, the first threshold is 5GB (gigabytes), the second threshold may be 2GB, and the like, but is not limited thereto. The electronic equipment can actively stop grabbing the air interface data packet according to the currently available memory, and the situation that the memory is exploded when a user forgets to stop grabbing the air interface data packet can be prevented, so that the performance of the electronic equipment is reduced.

In some embodiments, the captured air interface data packets may be stored every time a data packet is captured, or may be stored according to a certain time period, for example, the captured data packets are stored every 10 seconds. Optionally, after the user triggers the capture stop button, that is, the electronic device receives the capture stop instruction, all data packets captured this time may be stored, and the like.

As a specific implementation, the grabbed air interface data packet is stored, and when the data amount of the grabbed air interface data packet reaches a third threshold, the grabbing operation may be suspended, and the grabbed air interface data packet is stored. Optionally, the third threshold may be set according to actual requirements, for example, when the captured air interface data packet reaches 2GB, the capture operation may be suspended first, and the captured air interface data packet is stored. After the captured air interface data packet is saved, if the current residual memory is not less than the second threshold value, the air interface data packet can be continuously captured. The data volume of the air interface data packet stored every time is only the third threshold, so that the problem that the stored air interface data packet is copied or transmitted too slowly due to the fact that the stored air interface data packet is too large when the stored air interface data packet is copied or transmitted subsequently can be prevented, and the efficiency of copying, transmitting and the like of the air interface data packet can be improved.

In some embodiments, when storing the captured air interface data packet, a name input prompt message may be displayed on the second display interface, where the name input prompt message may be used to prompt the user to input a name of the stored air interface data packet. After the name of the air interface data packet input by the user is obtained, the storage progress can be displayed, so that the user can conveniently know the storage progress of the air interface data packet.

As shown in fig. 8 (a), when the electronic device stores the captured air interface data packet, the electronic device may display name input prompt information 802 on the second display interface 610, and after the user inputs the name of the air interface data packet in the displayed name input prompt information 802 and confirms the input name, as shown in fig. 8 (b), the electronic device may display a saving progress 802 on the second display interface 610.

Step 718, outputting a third display interface including an air interface packet list, where the air interface packet list includes at least one captured air interface data packet.

When the electronic device stops grabbing the air interface data packet, that is, after the current grabbing of the air interface data packet is finished, a third display interface including an air interface packet list can be output, wherein the air interface packet list can at least include the stored air interface data packet. Optionally, the user may also jump to the third display interface by triggering a log list key in the second display interface, and display the empty package list.

The user can select any one or more empty data packets in the empty packet list to upload to the server, and can also perform deletion operation for deleting the empty data packets on the third display interface, and rename the empty data packets.

And step 720, responding to the uploading operation aiming at the target air interface data packet in the air interface packet list, uploading the target air interface data packet to a server, and displaying the uploading progress.

The user can select an air interface data packet to be uploaded from the air interface packet list 902 to upload.

As shown in fig. 9B, if the user selects the air interface packet 2 to upload to the server, the air interface data packet corresponding to the air interface packet 2 may be uploaded to the server, and the uploading progress is synchronously displayed.
