1. var fs = require("fs");
   
2. let PostFileType = req.query.PostFileType;
   
3. let time = new Date().getTime();
   
4. const file = req.files.file;
   
5. let fileDate = moment().format('YYYY-MM-DD');
   
6. let name = `${new Date().getTime().toString()}_${file.name}`;
   
7. let DisplayName = `${file.name}`;
   
8. let dir = './routes/temp/' + fileDate
   
9. //判断目录是否存在,如果不存在,则新建目录
   
10. //递归创建
    
11. if (!fs.existsSync(dir)) {
    
12.     fs.mkdirSync(dir, {
    
13.         recursive: true
    
14.     });
    
15. }
