Is the

baseurl variable used anywhere after a + = operation? The error will be reported if it is not used.

English is very important to programmers. If this is prompted in Chinese, I think you should know what to do.
Let me help you translate
baseurl assigned a value, but never used it.
do you know how to do this one?

literally, you don't use this variable. In the code you give, baseurl is assigned a variety of values, but does not use baseurl . For example: assigned to other variables, as function parameters.
