回答： Steven Lord 2022-1-3

if I encode the following text

str = 'Hello\nWorld';
enc = urlencode(str)

I get this output that is wrong:

enc =
'Hello%5CnWorld'

instead of this one that would be the correct one:

enc =
'Hello%0AWorld'

Is it possible to change the behavior so that '\n' is converted into '%0A' instead of '%5Cn'?

在 MATLAB Online 中打开

s1 = 'Hello\nWorld'
s1 = 'Hello\nWorld'
s1E = urlencode(s1)
s1E = 'Hello%5CnWorld'
s2 = sprintf('Hello\nWorld')
s2 = 
    'Hello
     World'
s2E = urlencode(s2)
s2E = 'Hello%0AWorld'
whos
  Name      Size            Bytes  Class    Attributes

  s1        1x12               24  char               
  s1E       1x14               28  char               
  s2        1x11               22  char               
  s2E       1x13               26  char               

s1 contains 12 characters including both \ and n while s2 contains 11 including a newline. Just because text includes the pair of characters '\n' doesn't mean that's treated as a newline.
