java - .html和.html

Question

url: cxt+"basicRatesInfo.htm"和url: cxt+"basicRatesInfo.html有什么区别？为什么从ajax中的URL调用.html调不过去？？

Answer 1

basicRatesInfo.html This file does not exist on the server.

The extension actually only affects the windows system, and the extension is not important elsewhere. For example, in a browser, it mainly looks at the MIME type in the http header.
In fact, this is a good method, so it is also adopted by other software or systems.
In the past, the extension on Windows could only have 3 characters, so the file name could only be written htm，后来没有这个限制了，所以也可以写html, but they had the same meaning, but because the file names were different, they were still two different files.

Answer 2

htm is the abbreviation of html, there is no other difference. The reason why html cannot be called is because your URL is wrong
