bug for omitting query and hash from pathname

[shokai]

Hi, I found a bug and I'm reporting it.

• The querystring is removed from the pathname.
• The hash is also removed from the pathname.
• If I add both querystring and hash, the querystring are not removed from the pathname.

const page = require('./')

page('/foo', ctx => {
  console.log('canonicalPath', ctx.canonicalPath)
  console.log('pathname', ctx.pathname)
})

page('/foo?hello=there')
page('/foo#hash')
page('/foo?hello=there#hash') // query and hash

output

canonicalPath /foo?hello=there
pathname /foo
canonicalPath /foo#hash
pathname /foo
canonicalPath /foo?hello=there#hash
pathname /foo?hello=there
