DETAILED DESCRIPTION

[0017] Embodiments of the present invention provide a method, device, and storage medium for parsing Line chat records in an iOS system.

[0018] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0019] In the description of the embodiments disclosed herein, the term "including" and similar terms should be understood as open inclusion, i.e., "including but not limited to." The term "based on" should be understood as "based, at least in part, on." The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment." The terms "first," "second," etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0020] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 In one embodiment of the present invention, a method for parsing Line chat records in an iOS system includes: 101. Connect to the iCloud cloud database based on the preset iCloud access credentials; In this example, the iCloud access credentials are the user's iCloud account and password, and the simulated device is used to connect to the iCloud cloud database. You can use the PyiCloud library to write the iCloud access credentials into the encapsulated function PyiCloudService('your_apple_id@example.com', 'your_password') to connect to the iCloud cloud database. If the iCloud cloud database has verification settings, you can respond to the iCloud cloud database verification by calling the ORC plug-in to identify the verification code or by retrieving the verification information via SMS. After a successful verification response, the iCloud cloud database is connected.

[0021] For further information, see Figure 2 , Figure 2 This is a schematic diagram of a specific embodiment before step 101 of the method for parsing Line chat records in the iOS system in an embodiment of the present invention. The following specific implementation methods are included before step 101: 1011. Connect to the pre-installed backup device; 1012. Call the backup device and connect to the iCloud cloud database by pre-setting the iCloud access credentials; 1013. Upload the Line chat history in the backup device to the iCloud cloud database for backup.

[0022] In steps 1011-1013, a USB cable is used to connect the iOS device to the device to which the Line chat history data is to be backed up. The USB device is then used to access the iCloud cloud database using the iCloud account and password. The Line chat history from the iOS device is uploaded to a container in the iCloud cloud database for backup. During the upload process, the Line chat history is tagged with the name and device ID of the uploading device.

[0023] 102. Send a data download request to the iCloud cloud database, and receive the Line encrypted data and the device ID corresponding to the Line encrypted data fed back by the iCloud cloud database; In this embodiment, after logging into the iCloud cloud database, the encrypted Line data in the container corresponding to the iCloud access credentials is downloaded as a data download request. It should be noted that Line chat history is uploaded to the iCloud cloud database in encrypted form, so the encrypted Line chat history is downloaded. The encrypted Line data and the device ID corresponding to the encrypted Line data are returned from the iCloud cloud database.

[0024] For details, please refer to Figure 3 , Figure 3 This is a specific embodiment of step 102 of the method for parsing Line chat records in the iOS system in an embodiment of the present invention. Step 102 includes the following specific implementation methods: 1021. Construct and generate a verification request based on the iCloud access credential, wherein the verification request includes: a proxy address; 1022. Send the verification request to the iCloud cloud database, and receive verification data returned by the iCloud cloud database based on the proxy address; 1023. Based on a preset iCloud simulation component, verify the verification data and generate a user list, wherein the user list includes: N backup device names, where N is a positive integer; 1024. Receive a device selection instruction, and mark the N backup device names according to the device selection instruction to obtain marked device names; 1025. Send the marked device name to the iCloud cloud database and establish a connection with the iCloud cloud database.

[0025] In steps 1021-1025, the iCloud access credentials are used to assemble the ID information in the HTTP protocol, and the proxy address is also encapsulated into the HTTP protocol to construct a verification request.

[0026] The generated verification request is sent to the iCloud cloud database. The proxy address can be set to the address of other devices. The iCloud cloud database authenticates the iCloud access credentials based on the verification request. After the authentication is successful, a notification of successful authentication and a verification data are sent to the proxy address. Simulate the iCloud Drive component or CloudKit API component to access the data stored in iCloud. After verifying and confirming the verification data, return the data list to the iCloud cloud database to obtain the user list in the iCloud cloud database. There are multiple backup device names in the user list. The latest backup device name can be selected by default, or it can be set to select a device name with specific characters, or the user can click to select an instruction to select one of the multiple backup device names to obtain a marked device name. Here, the device name can be a user-defined name, device ID, device model and other information. The backup information uploaded to the iCloud cloud database is not completely consistent with the information required by the Line server. It only needs to be that the backup information uploaded to the iCloud cloud database is a superset of the information required by the Line server.

[0027] The marked device name is sent to the iCloud cloud database, and the iCloud cloud database establishes a communication connection between the cloud backup data container corresponding to the marked device name, device ID, etc. and the proxy address.

[0028] Furthermore, step 1023 includes the following specific implementations: 10231. Based on the preset iCloud Drive simulation component and the preset CloudKit simulation component, the verification data is verified and processed to generate a user list.

[0029] In step 10231, the iCloud Drive simulation component and the CloudKit simulation component are two components simulated by code. The iCloud Drive simulation component is used to store and manage user files, and the CloudKit simulation component is used to store and query application data, access data stored in iCloud, verify and confirm the verification data, and return the data list to the iCloud cloud database to obtain the user list in the iCloud cloud database.

[0030] Furthermore, step 1021 includes the following specific implementations: 10211. Based on the HTTPS / TLS protocol, encapsulate the iCloud access credentials and proxy address and generate a verification request.

[0031] In step 10211, the HTTPS / TLS protocol is a network communication security protocol, which is a combination of HTTP and TLS / SSL protocols. It encapsulates the iCloud access credentials and proxy address in the protocol header information, generates a verification request, and meets the end-to-end requirements of iCloud.

[0032] 103. Send the Line encrypted data and the device ID to the Line server, and receive chat parsed data returned by the Line server.

[0033] In this embodiment, a Line app is simulated to connect to a Line server. The Line server needs to verify the device used by the app, so the device ID must also be sent to the Line server. The Line encrypted data and the device ID are sent to the Line server, which parses the encrypted data and obtains the decrypted chat data. This allows the plaintext chat data to be retrieved without forcibly decrypting the Line encrypted data.

[0034] For details, please refer to Figure 4 , Figure 4 This is a specific embodiment of step 103 of the method for parsing Line chat records in the iOS system in an embodiment of the present invention. Step 103 includes the following specific implementation methods: 1031. Generate JSON data and entity class data corresponding to the JSON data based on the Line encrypted data and the device ID. 1032. Send the JSON data and the entity class data to the Line server, and receive the chat parsing data returned by the Line server.

[0035] In steps 1031-1032, the Line encrypted data and device ID are assembled according to the JSON format accepted by the Line server. The instructions are set to parse the chat data to obtain the entity class data corresponding to the JSON data and the JSON data. The entity class data corresponding to the JSON data and the JSON data is then sent to the Line server. The Line server decrypts the entity class data based on the JSON data and receives the chat parsed data returned by the Line server.

[0036] Specifically, after step 103, the following specific implementation methods are also included: 104. In a preset display interface, the chat parsing data is displayed and processed to obtain Line chat record data.

[0037] In step 104, the chat parsed data is displayed in a preset display interface in a text format such as XML format and HTML format to obtain Line chat record data, making it convenient for users to view relevant information.

[0038] Specifically, after step 103, the following specific implementation methods are also included: 105. Save the chat parsed data into a preset SQL database.

[0039] In step 105, the chat parsing data is saved into a data table according to the chat records with different objects. The data table has corresponding fields such as MesLocalID, Message, and Status, which respectively represent the ID, chat content, and status of the chat content in the current conversation. The data is stored in a relational database such as an SQLite database and a MySQL database so that users can store the chat records.

[0040] In an embodiment of the present invention, by pre-setting iCloud access credentials and downloading Line encrypted data from the iCloud cloud database, encrypted data related to Line chat data can be obtained on a device without the need to install the Line application. Using the device ID and Line encrypted data, a proxy accesses the Line server for decryption to obtain chat parsing data. This solution obtains Line chat history data through iCloud and simulates the Line application using the Line server to decrypt and parse the Line chat history. This solution eliminates the need to adjust the data structure of the Line chat data and can parse Line chat data regardless of whether it is encrypted or private, thus enabling parsing of Line chat history data on the iOS system.
