node.js - Nodejs 中的 fs.readFileSync() 错误

Question

我正在 nodejs 中使用 require('fs'); 调用同步调用

var folder_path = '/home/abc';
var myfiles = ['a.png','b.png'];
_.each(myfiles, function(name){
    var data = fs.readFileSync(folder_path+'/'+name);
    if(data){
       // Some operation
    }
});

在调用该函数时，我收到错误:EISDIR，对目录的非法操作

fs.js:488
  var r = binding.read(fd, buffer, offset, length, position);
              ^
Error: EISDIR, illegal operation on a directory
at Object.fs.readSync (fs.js:488:19)

error: Forever detected script exited with code: 8

详情

$ node -v
v0.10.37

$ nodejs -v
v0.10.37

$ npm -v
1.4.28

任何答案都将受到重视。

谢谢

我认为你可能不得不满足于“myfiles.forEach(function(name)”

var folder_path = '/home/abc';
var myfiles = ['a.png','b.png'];
myfiles.forEach(function(name){
    var data = fs.readFileSync(folder_path+'/'+name);
    if(data){
             // Some operation
            }
});
