如何从内容字符串获取文件路径和文件名？

Question

How can I get just get the file path and file name from a string?

My string looks like the following

GET /content/random.gif HTTP/1.0

I tried the regex ^(.+)/([^/]+)$ , but it didn't work. Is there an alternative to regex?

Answer 1

Just to extend the comments of using a string split. To get the filepath and filename you could use the following:

 var str = 'GET /content/random.gif HTTP/1.0'; var file = str.split(' ')[1]; var filepath = file.substr( 0,file.lastIndexOf('/')+1 ); var filename = file.substr( file.lastIndexOf('/')+1 ); console.log('filepath: '+filepath); console.log('filename: '+filename); 

Answer 2

Short, simple and reliable

var str = 'GET /content/random.gif HTTP/1.0';
var re = /^.+? (.*)\/([^\/]*) .+?$/;
var m = str.match(re);

var filepath = m[1];
var filename = m[2];
