[0022] Figure 1 It is a schematic diagram of the overall technical framework of an embodiment of the present invention;

[0023] Figure 2 It is an implementation flow chart of an embodiment of the present invention. DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0025] The present invention mainly includes UI display, software package search, software package list display, download link analysis, download and shortcut operation. The overall technical architecture is as follows: Figure 1 As shown, including:

[0026] (1) UI interface: The UI interface uses the simple and easy-to-use tkinter library, which mainly uses drop-down boxes, lists, buttons, text input boxes, etc.

[0027] (2) Search module: used for software package search, mainly uses requests to obtain the web page content of the spliced ​​URL, and uses xpath to parse the software package and version.

[0028] (3) Display module: The searched software packages and versions are displayed in the UI interface in the form of a list.

[0029] (4) The download module splices the URL of the software package details page based on the obtained software package and version, obtains the HTML content, and then uses xpath / re / BeautifulSoup technology to parse the download link.

[0030] (5) After obtaining the download connection, the download module uses request and file.write to download and save the file.

[0031] (6) The download module also includes a quick operation part, which is implemented by calling the execution program using the subprocess library.

[0032] Based on the above technical framework, the specific implementation plan of this embodiment is as follows Figure 2 As shown, including:

[0033] 1. First, select the warehouse. Set the drop-down box for warehouse selection in the UI interface, and select kylin-desktop, kylin-gf, kylin or kylinos-desktop from the drop-down box, and record it as branch_name.

[0034] 2. Enter the keyword of the software package to be searched, record it as search_key, set the "Fuzzy Search" button in the UI interface, and execute the function search_name to obtain the software package list. In the function, first press url = base_url + " / " + branch_name + " / + search? text = "+ search_key + "& batch = 100& start = "+

[0035] The rule of str(search_name_start) spells out the url to be accessed for searching software packages. Among them, base_url is "https: / / dev.kylinos.cn", the initial value of search_name_start is 0, and the page turning function is realized by modifying this value later. batch=100 means loading 100 results. If there are less than 100 results, the actual number of results will be loaded. Then use requests.get(url,verify=False,headers=headers).content to obtain the web page content, and then use lxml and xpath to parse the web page content, extract the searched number and software package list, and display them on the UI interface through the display module. The list control is recorded as search_name_dropdown_listbox. If the number of results is greater than 100, set the next page button to click, add 100 to search_name_start, and then call the search_name function. Similarly, set the previous page button to click, subtract 100 from search_name_start, and then call the search_name function.

[0036] 3. Select a package name in the search_name_dropdown_listbox and set the selected package name to be displayed in deb_name_entry. You can also enter the exact package name into deb_name_entry and record the package name as deb_name.

[0037] 4. Click the "Search" button to execute the search function to obtain the software package version list. First, write out the webpage address according to the rule of publishinghistory=base_url+" / "+branch_name+" / +source / "+deb_name+" / +publishinghistory?batch=100&start="+str(search_versions_start), where the initial value of search_versions_start is 0. The page turning function is realized by modifying this value later. batch=100 means loading 100 results. If there are less than 100 results, the actual number of results will be loaded. Then use requests.get(publishinghistory, verify=False, headers=headers).content to get the webpage content, and then parse the webpage content with lxml and xpath, extract the searched number and package version list, and display them on the UI interface through the display module. The list control is recorded as versions_dropdown_listbox, and the package version and the corresponding href tag content are saved in version_dict. The href format is such as " / kylin-gf / +source / peony / 3.20.4.14-0k3.11gf3.66". If the number of results is greater than 100, set the next page button to click, add 100 to search_versions_start, and then call the search function. Similarly, set the previous page button to click, subtract 100 from search_versions_start, and then call the search function.

[0038] 5. Select a version in the package version list, record it as selected_value, and then spell out the URL according to the rule of url=base_url+version_dict[selected_value], similar to "https: / / dev.kylinos.cn / kylin-gf / +source / peony / 3.20.4.14-0k3.11gf3.66". Then set the URL to input_details_url for display. You can also enter the accurate package details address yourself, record it as details_url.

[0039] 6. Set the "View changelog" button on the UI interface. After clicking it, execute the get_changelog function to view the change log. In the function, use requests to get the content of details_url, and then use BeautifulSoup to match the changelog text.

[0040] 7. Set the "Get Source Code" button on the UI interface, and click it to execute the get_code_links function. In the function, use requests to get the details_url content, and then use the re regular expression to match links containing .tar.xz, .dsc, .tar.gz, .debian.tar.xz, orig.tar.gz, and tar.gz.asc. Put the matched links into code_links, concatenate the links, and call the copy_to_clipboard function to copy them to the clipboard.

[0041] 8. Set the "Download Source File" button on the UI interface. Click it to execute the download_files function and pass code_links as a parameter. In the function, use requests with file.write to download and save files. The saved path defaults to the deb_download path in the user's home directory, which can be changed freely. The path is recorded as save_path.

[0042] 9. Set the drop-down box for selecting the architecture on the UI interface. After clicking the drop-down box for selecting the architecture, select one of "arm64", "amd64", "loongarch64", "mips64el", "sw64", and record it as platform.

[0043] 10. Set the "Get deb address" button on the UI interface, click it and execute the get_deb_links function. In the function, use requests to get the content of details_url, and then use BeautifulSoup with platform to match the details link of the architecture, such as " / kylin-gf / +source / peony / 3.20.4.14-0k3.11gf3.66 / +build / 1473010", and combine it with base_url to become "https: / / dev.kylinos.cn / kylin-gf / +source / peony / 3.20.4.14-0k3.11gf3.66" / +build / 1473010", which is the package details link under the current architecture, and then use requests to obtain the content of the details page, and use BeautifulSoup to match all links containing the words platform+.d, which is the final download link of this version of the package under this architecture, such as "http: / / dev.kylinos.cn / +librarian / 12151195 / libpeony-dev_3.20.4.14-0k3.11gf3.66_amd64.deb", etc., and then save it to deb_links, splice the links, and call the copy_to_clipboard function to copy it to the clipboard.

[0044] 11. Set the "Download deb file" button on the UI interface. Click it to execute the download_files function and pass deb_links as a parameter. In the function, use requests with file.write to download and save files.

[0045] 12. Set the "Open Download Path" button on the UI interface. Click it to execute the open_save_path function. In the function, use subprocess.run(["xdg-open",save_path]) to open the file browser and enter the download path.

[0046] 13. Set the "Terminal entry path" button on the UI interface, and execute the open_terminal function after clicking it. In the function, use subprocess.Popen(["mate-terminal", "--working-directory", save_path]) to call the terminal to enter the download path.
