Need access to query string in rewriteRequestPath

[RickCarlino]

Example URL: http://localhost:8080/uri-res/N2R?urn:sha1:XKM123

I am attempting to map SHA1 values to local file system paths:

const staticConf = serveStatic({
  root: "./gnutella-library",
  rewriteRequestPath(requestPath) {
    // Example of incoming request:
    // /uri-res/N2R?urn:sha1:XKMJALOQS2SFZA442DDWMSXQEAPEABQQ
    
    // What `requestPath` looks like: "/uri-res/N2R"
    return getPathFromSha1(requestPath);
  },
});

The URL format is from a network protocol standard, so I unfortunately cannot change it.
I only have access to "/uri-res/N2R" which is not enough information to pull up the true file path.

Is there a way to access the queryString value of the request when re-writing the request path?

I was able to use middleware to re-write the path for now.
