go get github.com/FusionAuth/go-client/pkg/fusionauth
The following example uses the FusionAuth Go client to create a request handling function that logs in a user:
package example
import (
"encoding/json"
"net/http"
"net/url"
"time"
"github.com/FusionAuth/go-client/pkg/fusionauth"
)
const host = "http://localhost:9011"
var apiKey = "YOUR_FUSIONAUTH_API_KEY"
var httpClient = &http.Client{
Timeout: time.Second * 10,
}
var baseURL, _ = url.Parse(host)
// Construct a new FusionAuth Client
var auth = fusionauth.NewClient(httpClient, baseURL, apiKey)
// Login logs in the user using the FusionAuth Go client library
func Login() http.HandlerFunc {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// Read response body
var credentials fusionauth.LoginRequest
defer r.Body.Close()
json.NewDecoder(r.Body).Decode(&credentials)
// Use FusionAuth Go client to log in the user
authResponse, errors, err := auth.Login(credentials)
if err != nil {
http.Error(w, err.Error(), http.StatusBadRequest)
return
}
// Write the response from the FusionAuth client as JSON
var responseJSON []byte
if errors != nil {
responseJSON, err = json.Marshal(errors)
} else {
responseJSON, err = json.Marshal(authResponse)
}
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(http.StatusOK)
w.Write(responseJSON)
})
}
You can also call the API directly without logging a user in. This code uses an API key to determine the number of tenants in a FusionAuth installation.
package main
import (
"net/http"
"net/url"
"time"
"fmt"
"github.com/FusionAuth/go-client/pkg/fusionauth"
)
const host = "http://localhost:9011"
var apiKey = "API KEY"
var httpClient = &http.Client{
Timeout: time.Second * 10,
}
func main() {
var baseURL, _ = url.Parse(host)
// Construct a new FusionAuth Client
var client = fusionauth.NewClient(httpClient, baseURL, apiKey)
// for production code, don't ignore the error!
tenantResponse, _ := client.RetrieveTenants()
fmt.Print(len(tenantResponse.Tenants))
}
If you are modifying the go client and want to test it locally, follow these steps:
go to directory where you have go code checked out.
mkdir test2
cd test2
go mod init example.com/test/fusionauth
go mod tidy
vi test.go # put in your test code, in the main package
Then edit go.mod
and add these lines at the bottom:
require (
github.com/FusionAuth/go-client v1.0.0
)
replace (
github.com/FusionAuth/go-client v1.0.0 => ../go-client
)
Then you can run it: go run test.go # or go build
