某些情况下目录会被当作普通文件

[rockuw]

            if(strConType == "application/x-directory"){
              mode |= S_IFDIR;
            }else if(path && 0 < strlen(path) && '/' == path[strlen(path) - 1]){
              if(strConType == "binary/octet-stream" || strConType == "application/octet-stream"){
                mode |= S_IFDIR;
              }else{
                mode |= S_IFREG;
              }
            }else{
              mode |= S_IFREG;
            }

判断一个object是否是目录的逻辑，要求content-type是"application/x-directory" or "binary/octet-stream" or "application/octet-stream"，而不是直接根据文件后缀有没有"/"来判断。

这有点奇怪，某些工具会生成一个目录文件，但是content-type不符合要求，导致其被当成普通文件对待。
