这是后端代码:
res.statusCode = 400
res.setHeader 'Content-Type', 'text/plain'
res.end 'Invalid API endpoint.'
当我从终端卷曲时,我得到:
Invalid API endpoint.%
“%”符号显示反色。
为什么那里会出现“%”?

这标记了一个部分行,因为响应发送没有尾随换行符。来自

PROMPT_SP <D> Attempt to preserve a partial line (i.e. a line that did not end with a newline) that would otherwise be covered up by the command prompt due to the PROMPT_CR option. This works by out‐ putting some cursor-control characters, including a series of spaces, that should make the terminal wrap to the next line when a partial line is present (note that this is only success‐ ful if your terminal has automatic margins, which is typical).
When a partial line is preserved, by default you will see an
inverse+bold character at the end of the partial line: a "%"
for a normal user or a "#" for root. If set, the shell parame‐
ter PROMPT_EOL_MARK can be used to customize how the end of
partial lines are shown.
NOTE: if the PROMPT_CR option is not set, enabling this option
will have no effect. This option is on by default.
