By setting the physical path of the folder, the files in the directory are packaged and compressed and downloaded
Demo
Large file download test
This simulation generates a text file of 1 million lines, about 58M, which can be tested by yourself
Demo
The button sets the value of IsAsync to true for asynchronous download operation
Get the picture and display it
Simulate the situation where the verification code is generated directly from the front-end page or the uploaded image is not saved and displayed directly.
Demo
Since the test uses the files under wwwroot, there is no code generation, and wasm cannot access the wwwroot folder, so only the ssr mode is available for the test. wasm please test it yourself.
