simpleResponse.xml
文件里面要怎么写
为什么警告框跳不出来
simpleResponse.xml 这个文件在你测试的时候可以随便写点内容进去,比如"hello world!";
但真正的xml文件格式应该是像这样的
<?xml version="1.0" encoding="ISO-8859-1"?> <!-- Copyright w3school.com.cn --> <note> <to>George</to> <from>John</from> <heading>Reminder</heading> <body>Don't forget the meeting!</body> </note>
可以访问如下地址看效果

simpleResponse.xml 和这个 html 在同一路径下 ... 无所谓什么内容~
