node.js - 从 Nodejs 运行多个 Windows 命令

Question

当我的Windows服务器收到post请求时，我需要它来执行命令:

cd D:\project
git pull
mvn clean compile
cd target
java -jar app.jar -argument

我写了代码，但它不起作用:

const nodeCmd = require('node-cmd')

app.post((req, res) => {
  let command = `cd D:\project\my_project
                 git pull
                 mvn clean compile
                 cd target
                 java -jar app.jar ${req.body.arg}`;
  nodeCmd.get(command, (err, data, stderr) => {
    if(data) { 
     return res.json(data);
    }
    return err;
 });
})

这是错误消息:

{ Error: Command failed: cd D:projectmy_project && dir
The system cannot find the path specified.

命令字符串中的反斜杠不会被转义。您可以使用string.raw指示 JS 引擎将模板文字视为原始字符串。

let command = String.raw`cd D:\project\my_project
                         git pull
                         mvn clean compile
                         cd target
                         java -jar app.jar ${req.body.arg}`;
