allow custom encoders to handle nil pointers If a custom encoder is defined on a pointer of a type, allow that encoder to handle nil values. Encoders defined on non-pointer types will continue to be given the zero value of the type to encode (the existing behavior). Fixes #46
go-querystring is a Go library for encoding structs into URL query parameters.
import "github.com/google/go-querystring/query"
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:
