better handling of empty values in slices/arrays

if the slice or array has no values, skip it entirely.  This fixes
an issue where a struct field with a custom delimiter was included in
the returned url.Values with an empty string rather than being omitted
entirely (as is the case when there is no custom delimiter)

go-querystring is a Go library for encoding structs into URL query parameters.


import ""

go-querystring is designed to assist in scenarios where you want to construct a URL using a struct that represents the URL query parameters. You might do this to enforce the type safety of your parameters, for example, as is done in the go-github library.

The query package exports a single Values() function. A simple example:

type Options struct {
  Query   string `url:"q"`
  ShowAll bool   `url:"all"`
  Page    int    `url:"page"`

opt := Options{ "foo", true, 2 }
v, _ := query.Values(opt)
fmt.Print(v.Encode()) // will output: "q=foo&all=true&page=2"

See the package godocs for complete documentation on supported types and formatting options.


If you are looking for a library that can both encode and decode query strings, you might consider one of these alternatives:
