如何在Node.js中为请求设置当前工作目录？

Question

I know I can change the process directory using:

process.chdir('/temp/foo');

but I don't want to change the directory for all requests.

I would like to use a different working directory based on the request coming in. For example if the request is for an image, I want to change the working directory to the image directory. If the request is for an upload, I want to change the current working directory to the upload folder.

I have some other files in these folders specific to the type of request and it would be easier if I can set the current working directory for each request.

I do not want to change the working directory for all other requests being processed by the same server. Each request's working directory should be specific to that request.

When working with any path references just prepend the "working" directory:

function request1() {
  var workingDir = 'prefered/working/path';
  var path = path.resolve(workingDir, 'file.ext');
  var stats = fs.statSync(path);
}
