想用批处理调用外部node.js命令处理文本怎么解决？

xp3000

下面方式调用node处理文件时候乱码，怎么解决？

1. @if(0)==(0) echo off
   
2. REM.保存为ANSI编码
   
3. dir /b/a-d/oN "*.txt" | cscript -nologo -e:jscript "%~0"
   
4. pause & goto :EOF
   
5. @end
   
6. fso = new ActiveXObject("Scripting.FileSystemObject");
   
7. var shell = new ActiveXObject("WScript.Shell");
   
8. while (!WSH.StdIn.AtEndOfStream) {
   
9. var file = WSH.StdIn.ReadLine();
   
10. var command = 'cmd /c node -e "console.log(fs.readFileSync(\''+file+'\', \'UTF-8\'))"';
    
11. //var command = 'cmd /c node -e "require(\'fs\').readFile(\''+file+'\', \'UTF-8\', function(err, data){console.log(data)})"';
    
12. var execObject = shell.Exec(command);
    
13. var output = execObject.StdOut.ReadAll();
    
14. WScript.Echo(output);
    
15. }

一定得调用node.js来读取文件吗；
要么设置一下chcp试试呢

xp3000

加了这个后就不行了
shell.Run('chcp 65001', 0, true);
主要是node的语法网站上到处可以搜索出来，修改也就方便很多

回复 3# xp3000
@echo off
chcp 65001
不行的话第10行变量值改一下试试呢 var command = 'chcp 65001 && cmd /c node -e ....

也不行,找到一种方法,先对data使用encodeURIComponent编码,
然后在shell.Exec外部用decodeURIComponent对output进行解码,
但是效率就变差了,cscript不能支持JS ES13太遗憾了

10. WScript.Echo(file+' 内容：\n');
    
11. //var command = 'cmd /c node -e "console.log(fs.readFileSync(\''+file+'\', \'UTF-8\').toString(\'ascii\'))"';
    
12. var command = '\
    
13. cmd /c node -e "require(\'fs\').readFile(\''+file+'\', \'UTF-8\', function(err, data){\
    
14. console.log(encodeURIComponent(data))\
    
15. })"';
    
16. var execObject = shell.Exec(command);
    
17. var output = execObject.StdOut.ReadAll();
    
18. WScript.Echo(decodeURIComponent(output));
    
19. }
