HTTP Negotiation
What does this library?
This library provides a simple way to negotiate the content type of HTTP request.
It supports:
Installation
go get gitlab.schukai.com/oss/libraries/go/network/http-negotiation
Note: This library uses Go Modules to manage dependencies.
Usage
Content Negotiation
With the Type
function you can negotiate the content type of HTTP request.
package main
import (
"net/http"
"gitlab.schukai.com/oss/libraries/go/network/http-negotiation"
)
func handleRequest(w http.ResponseWriter, r *http.Request) {
n := negotiation.New(r.Header)
if n.Type("application/json") == "application/json" {
w.Header().Set("Content-Type", "application/json")
w.Write([]byte(`{"message": "Hello World!"}`))
return
}
}
Accept Content Type
With the ContentType
function you can negotiate the content type of HTTP request.
package main
import (
"net/http"
"gitlab.schukai.com/oss/libraries/go/network/http-negotiation"
)
func handleRequest(w http.ResponseWriter, r *http.Request) {
n := negotiation.New(r.Header)
if n.ContentType("application/json") != "" {
// ...
}
}
Language Negotiation
With the Language
function you can negotiate the language of HTTP request.
package main
import (
"net/http"
"gitlab.schukai.com/oss/libraries/go/network/http-negotiation"
)
func handleRequest(w http.ResponseWriter, r *http.Request) {
n := negotiation.New(r.Header)
if n.Language("en-GB", "en") != "en" {
// ...
}
}
Charset Negotiation
With the Charset
function you can negotiate the charset of HTTP request.
package main
import (
"net/http"
"gitlab.schukai.com/oss/libraries/go/network/http-negotiation"
)
func handleRequest(w http.ResponseWriter, r *http.Request) {
n := negotiation.New(r.Header)
if n.Charset("utf-8", "iso-8859-1") != "utf-8" {
// ...
}
}
Encoding Negotiation
With the Encoding
function you can negotiate the encoding of HTTP request.
package main
import (
"net/http"
"gitlab.schukai.com/oss/libraries/go/network/http-negotiation"
)
func handleRequest(w http.ResponseWriter, r *http.Request) {
n := negotiation.New(r.Header)
if n.Encoding("gzip", "deflate") != "gzip" {
// ...
}
}
Contributing
Merge requests are welcome. For major changes, please open an issue first to discuss what you would like to change. Please make sure to update tests as appropriate.
Versioning is done with SemVer. Changelog is generated with git-chglog
Commit messages should follow the Conventional Commits specification. Messages are started with a type, which is one of the following:
- feat: A new feature
- fix: A bug fix
- doc: Documentation only changes
- refactor: A code change that neither fixes a bug nor adds a feature
- perf: A code change that improves performance
- test: Adding missing or correcting existing tests
- chore: Other changes that don't modify src or test files
The footer would be used for a reference to an issue or a breaking change.
A commit that has a footer BREAKING CHANGE:
, or appends a ! after the type/scope,
introduces a breaking API change (correlating with MAJOR in semantic versioning).
A BREAKING CHANGE can be part of commits of any type.
the following is an example of a commit message:
feat: add 'extras' field
