Express res.sendfile 抛出禁止错误 [英] Express res.sendfile throwing forbidden error

问题描述

我有这个代码:

res.sendfile( '../../temp/index.html' )

然而，它抛出这个错误:

However, it throws this error:

Error: Forbidden

at next (/Users/Oliver/Development/Personal/Reader/node_modules/express/node_modules/connect/lib/proto.js:199:15)

谁能告诉我为什么会这样?

Can anyone tell me why this might be?

推荐答案

我相信是相对路径的原因；../"被认为是恶意的.先解析本地路径，再调用res.sendfile.您可以预先使用 path.resolve 解析路径.

I believe it's because of the relative path; the "../" is considered malicious. Resolve the local path first, then call res.sendfile. You can resolve the path with path.resolve beforehand.

var path = require('path');
res.sendFile(path.resolve('temp/index.html'));
