Special characters & escapes in bat

Look at the example first

curl -H "Content-Type:application/json"-X POST-d "{\"value\":\"type=username&username=xxxx0001\"}"http://127.0.0.1:8111/loginbyother//The above command is to wrap the line for the convenience of reading the code, it is actually a whole line

Executing the above statement in Windows Terminal will always report an error

curl: no URL specified!curl: try 'curl --help' for more information

I always thought it was a problem with quotation marks, so I used various methods to escape the quotation marks, and even used UrlEncode, but it didn't work. Finally, it was determined that it was the problem of the ampersand, because in windows, & means a commandconcatenation, so it must be escaped.

& escape ====> ^&

Then modify the code as follows

curl -H "Content-Type:application/json"-X POST-d "{\"value\":\"type=username^&username=xxxx0001\"}"http://127.0.0.1:8111/loginbyother//The above command is to wrap the line for the convenience of reading the code, it is actually a whole line

This kind of problem is often encountered in the bat file, and you can eat a lot of money and become wiser~
