After the revision of the national wisdom education platform for primary and secondary schools, all electronic textbooks can no longer be downloaded directly, which brings great inconvenience to teachers and parents who want to save them for future reference.

First of all, the PC side

I use the 360-speed browser X (I think all browsers of Google core should be able to do it), open the "National Intelligent Education Platform for Primary and Secondary Schools" (/), select "Course Teaching"-"Textbook Area", and then select information such as learning period, subject, version, grade, volume number, etc., and click the corresponding textbook to make it display normally. I take "Morality and Rule of Law", the first volume of the second grade of primary school, as an example.

After the textbook page can be displayed normally, right-click on the page and select the review element.

Click Network (or Network) and Get /XHR in the new window, and then refresh the browser page.

A pile of files will appear in the window on the right. We find pdf.pdf, then right-click the file and "open in a new tab". The browser will open this pdf file in a new tab.

There is a download button in the upper right corner of this new label. Click on it to download this pdf file. Remember to modify the file name after downloading.

Second, the mobile phone (Android)

Download and install the "Smart Primary and Secondary School" APP on your mobile phone, and register and log in.

Click on the following study, then click on the course teaching and textbook area above, select the corresponding learning cycle, subject, version, grade and volume, and click on the textbook; After buffering, the page corresponding to the teaching materials will be displayed on the screen (if you need teaching materials of multiple disciplines, you can repeat the above steps until all disciplines are buffered in the phone memory).

Close the App, open the "file manager" of the phone and find it.

Android \ data \ com.eduyun.app.factory.ykt/files/course folder, in which all files have a long string of characters and no suffix, and these files are buffered pdf files.

You can copy it to other folders on your computer or mobile phone and modify it into a file with a suffix of pdf.
