node.js의 path.join 방법 사용 설명

방법 설명:
여러 개의 매개 변수를 하나의 path로 조합하기 (상세한 예는 보십시오)
구문:

 
  
 path.join([path1], [path2], [...]) 
  
 
 

이 방법은 path 모듈에 속하기 때문에 사용하기 전에 path 모듈을 도입해야 합니다. (var path = require ("path")
예:

 
  
 path.join('/foo', 'bar', 'baz/asdf', 'quux', '..') 
  
 // returns 
  
 '/foo/bar/baz/asdf' 
  
 path.join('foo', {}, 'bar') 
  
 // throws exception 
  
 TypeError: Arguments to path.join must be strings 
  
 
 

소스:

 
  
 // windows version 
  
   exports.join = function() { 
  
     function f(p) { 
  
       if (!util.isString(p)) { 
  
         throw new TypeError('Arguments to path.join must be strings'); 
  
       } 
  
       return p; 
  
     } 
  
   
  
     var paths = Array.prototype.filter.call(arguments, f); 
  
     var joined = paths.join('\\'); 
  
   
  
     // Make sure that the joined path doesn't start with two slashes, because 
  
     // normalize() will mistake it for an UNC path then. 
  
     // 
  
     // This step is skipped when it is very clear that the user actually 
  
     // intended to point at an UNC path. This is assumed when the first 
  
     // non-empty string arguments starts with exactly two slashes followed by 
  
     // at least one more non-slash character. 
  
     // 
  
     // Note that for normalize() to treat a path as an UNC path it needs to 
  
     // have at least 2 components, so we don't filter for that here. 
  
     // This means that the user can use join to construct UNC paths from 
  
     // a server name and a share name; for example: 
  
     // path.join('//server', 'share') -> '\\\\server\\share\') 
  
     if (!/^[\\\/]{2}[^\\\/]/.test(paths[0])) { 
  
       joined = joined.replace(/^[\\\/]{2,}/, '\\'); 
  
     } 
  
   
  
     return exports.normalize(joined); 
  
   };
