This question involves two aspects of parameter construction:
- Password construction: encrypt the password when logging in, generate ciphertext and pass it to the server
- Several related parameters are constructed: no encryption algorithm is involved, and several variable values are generated after certain calculations for timestamps and random numbers.
The js knowledge points involved in this question:
(personal understanding, or wrong, follow-up understanding deepens and then adjusts)
- Webpack packaging: JS code will generate a fixed pattern after packaging it through wwebpack. This pattern has a standard three-stage pattern, 1. Self-executing function; 2. Loader; 3. Specific module code.
- When the code is called, it will pass the id corresponding to the module to the loader, and run the specified code through the loader.
