[1] Lua language in the Windows environment, file path wording
Example procedures are as follows:
1 -- test1
2 local file = io.open("E:\test\100.txt", 'rb')
3 if not file then
4 print('test1::invalid')
5 else
6 print('test1::ok')
7 end
8
9 -- test2
10 file = io.open("E:\\test\\200.txt", 'rb')
11 if not file then
12 print('test2::invalid')
13 else
14 print('test2::ok')
15 end
16
17 -- test3
18 file = io.open("E:/test/300.txt", 'rb')
19 if not file then
20 print(':: invalid Test3 ' )
21 is the else
22 is Print ( ' Test3 :: OK ' )
23 is End
24
25 - Demo
26 is Print ( ' \\ ' ); - backslach single slash
27 Print ( " \" " ); - - double double quote marks
28 Print ( " \" \ " " ); - double double quote marks
29 Print ( " \ ' "); - SINGLE single quote marks
30 Print ( " '' " ); - SINGLE single quote marks
31 is Print ( " \ [ " ); - left Square Bracket left bracket
32 Print ( " \] " ); - - right Square Bracket
Results of the:
test1::invalid test2::ok test3::ok \ " "" ' '' [ ]
As shown above.
[2] summary
(1) Linux System: Linux using the slash / as the path separator.
(2) Network Address: the web application by using the above system Linux, the current network addresses are used slash / as a delimiter.
(3) Windows System: Windows uses the backslash \ as the path separator.
（4）相对路径：相对于当前文件的路径；绝对路径：主页上的文件或目录在硬盘上的真正路径。
（5）几个特殊符号：
./：代表目前所在的目录。
../：代表上一层目录。
（6）Lua语言中，斜杠\为转义字符。
转义字符用于表示不能直接显示的字符，比如后退键，回车键等，如在字符串转换双引号可以使用 " \" "。
两个转义字符所对应的意义：两个\\代表一个\
