Cannot get .WithPath to handle URL-encoded value

[oloffl]

I am using httpexpect version 2.16.0 to test one of our endpoints that wants a url-encoded path.

It looks something like this

path := "some:data/thats/encoded@0.1.0
urlEncoded := url.QueryEscape(path)

e.GET("/data/{urlEncoded}").
  WithPath("urlEncoded", urlEncoded).
  Expect().
  Status(http.StatusOK)

httpexpect fails with the following output

GET /data/some%!A(MISSING)data%!F(MISSING)thats%!F(MISSING)encoded%!.(MISSING)0 HTTP/1.1

Any ideas on what I am doing wrong?

Hi, thanks for report. I can't reproduce it neither in 2.16.0 nor in master.

I've added a couple of tests for this case, all are passing: 97e9161

For me, when I pass url-encoded argument to WithPath, it is added to request path as-is, and then http.Client url-encodes the whole path when sending request. So that piece of the path is actually url-encoded twice when it comes to server. Server url-decodes it, and server handler sees original url-encoded argument.

The error you quoted seems like printf-like formatting was used, but TBH I have no idea when it can be used for URL paths.

Can you provide a minimal reproducible example? Ideally based on master branch.
