node中使用shell脚本的方法步骤

touch newFile.sh

chmod 777 newFile.sh 修改文件为可读可写可执行

//使用nodejs的子进程里面的文件读取方法

const { execFile } = require(‘child_process');

DocsService.publishAllDocs = (req, res) => {
 req.session.touch();
 const { docName, pathName, saveDocsList, docType } = req.body;
 var docText = req.body.docText;
 var newGit = req.body.newGit;
 //获取文件路径
 var filepath = path.join(__dirname, '../../bin/rnsource/publishAllDocs.sh');
 var fileArr, fileName, spath, dirnameBack, docbackList = [], docbackPath, docPath = "";
 var username = req.session.user_name;
 var str = docName+'/'+ pathName + '|'+ username;
 var reg = new RegExp(`^(${str})`);
 saveDocsList.map((item, index)=>{
   fileArr = item.pathName.split("/");
   fileName = fileArr[fileArr.length-1];
   if(docType == "docsify"){
     dirnameBack = fileName != "" ? `../../gitlib/docBackup/${docName}/docs/${item.pathName}`:`../../gitlib/docBackup/${docName}/docs/README.md`
   }else{
     spath = item.pathName.split(fileName)[0];
     dirnameBack = spath != "" ?'../../gitlib/docBackup/'+ docName+'/'+ spath +'/'+fileName:'../../gitlib/docBackup/'+ docName+'/' + fileName; 
   }

   docbackPath = path.join(__dirname, dirnameBack);
   docbackList.push(docbackPath);
   docPath += docbackPath + " ";
 })
 docPath += ""
 //cwd设置当前路径 我这边设置的就是nodejs代码js当前的位置
 execFile(filepath, [docName, docPath, docType], { cwd: '.' }, function(err, stdout, stderr){
   logger.info(stdout);
   if(err){
     loggerFileError({user:username,docName:docName,pathName:'all',operate:"gitbook文件一键发布",err});
     res.json({
       respCode: -1,
       errMsg: "一键发布失败"
     })
   }else{
     res.json({
       respCode: 0,
       msg: "一键发布成功"
     })
     gitPush({ docName, fileName, docbackPath: docbackList, username, pathName, docType })
     unblockFile({ docName, username, pathName, reg });
   }
 }) 
}

#$1文档最外层目录 $2当前修改的文件名 $3当前修改文件的目录
cd $(pwd)/gitlib/docs/$1
echo "come in"
for item in $2; do
  echo "${item}"
  cp -f ${item} ${item/docBackup/docs}
done
# echo "初始化进入"
echo "$(pwd)/gitlib/docs/$1"
if [ "$3" == "docsify" ];then
  #拷贝指定目录下的文件 如： $1/$3/$2 docs/cst/7e4ce1de04621e0b/
  #如 cp -rf ../../docBackup/wireless/docs/cst/7e4ce1de04621e0b/10708d589eedfffd.md ./docs/cst/7e4ce1de04621e0b/
  cp -rf ./docs ../../../public/docs/$1
else
  # 处理gitbook类型文档
  gitbook build
  echo "复制文档"
  cp -rf ./_book/* ../../../public/docs/$1
fi

## $2就是脚本里面接收的业务的传参 按格式拼接好的数据 如上面数据示例
## 循环使用 for...in 记得;后面一定要加上do去执行循环体 最后使用done结束循环
## item循环体的每个子项 如：/Users/Desktop/work/docManager/docServer/gitlib/docBackup/mygitbook/docs/d09985fc67088b35/d09985fc67088b35.md
for item in $2; do
  echo "${item}"
  cp -f ${item} ${item/docBackup/docs}
done
## ${item/docBackup/docs} 字符串替换
## 此处是吧item路径里面的docBackup替换成docs 详细解释请看下面的shell字符串替换

if[];then
 ...
else
 ...
fi

## 条件判断是使用[]而不是()
## []后面要加;
if [ "$3" == "docsify" ];then
  #拷贝指定目录下的文件 如： $1/$3/$2 docs/cst/7e4ce1de04621e0b/
  #如 cp -rf ../../docBackup/wireless/docs/cst/7e4ce1de04621e0b/10708d589eedfffd.md ./docs/cst/7e4ce1de04621e0b/
  cp -rf ./docs ../../../public/docs/$1
else
  # 处理gitbook类型文档
  gitbook build
  echo "复制文档"
  cp -rf ./_book/* ../../../public/docs/$1
fi
