javascript - Node Js CreateWriteStream不会写入目录

Question

我似乎无法使 fs.createFileStream 写入目录。

var filePath = fs.createWriteStream('./path/to/store/file.png');            
var rem = rquest('http://domain.com/img/img.png');

rem.on('data', function(chunk) {
    filePath.write(chunk);
    response.write(chunk);
});

rem.on('response', function(res){
    response.writeHead(200, res.headers);
});

rem.on('end', function() {
    response.end();
});

如果我将文件名传递到 CreateWritStream 中，它就可以正常工作

var filePath = fs.createWriteStream('file.png');

我做错了什么？

Answer 1

正如@thefourtheye 在评论部分所述

It will not create the directories on its own. All the directories in the path should exist and should be writable.

是正确的解决方案。
