Members of the developer community have requested examples for OAuth implementations in different languages. We’ve created a few examples which can be found here, but in recognition of the talented developers in our community, we wanted to invite you to share your own!
Feel free to contribute your own examples of OAuth Client Credentials flow in this thread!
Golang example for using the golang oauth client for the Client Credential flow.
I felt like most other examples weren’t using the oauth2 library, and this makes it easy, plus it gives you auto-refresh of the oauth credential if it expires.
package main
import (
"context"
"io/ioutil"
"log"
"golang.org/x/oauth2/clientcredentials"
)
func main() {
// Setup oauth2 config
conf := &clientcredentials.Config{
ClientID: "client_id_here",
ClientSecret: "client_secret_here",
TokenURL: "https://us.battle.net/oauth/token",
}
// Get a HTTP client
client := conf.Client(context.Background())
// Use the client, to get a WoW boss, and print the result
resp, err := client.Get("https://us.api.blizzard.com/wow/boss/24723")
if err != nil {
log.Fatal(err)
}
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}
log.Println("response: ", string(body))
}
In C#
private OAuthToken RequestAuthorizationToken()
{
var client = new RestClient("https://us.battle.net/oauth/token");
var request = new RestRequest(Method.POST);
request.AddHeader("cache-control", "no-cache");
request.AddHeader("content-type", "application/x-www-form-urlencoded");
request.AddParameter("application/x-www-form-urlencoded", $"grant_type=client_credentials&client_id={ClientId}&client_secret={ClientSecret}", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
var token = JsonConvert.DeserializeObject<OAuthToken>(response.Content);
}
public class OAuthToken
{
public string access_token { get; set; }
public string token_type { get; set; }
public int expires_in { get; set; }
public string scope { get; set; }
}
I’m kinda late to the game, but I work in java. Here’s an app that gets the token and does a few requests
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;
import java.util.logging.Logger;
import org.json.JSONObject;
/**

*
* For this app to work, you need to download and include in your classpath
* json.jar which can be downloaded from https://github.com/stleary/JSON-java
* (direct link https://search.maven.org/remotecontent?filepath=org/json/json/20210307/json-20210307.jar)
*
* You will also have to enter your own CLIENT_ID & CLIENT_SECRET obtained through
* blizzard OAuth service (https://develop.battle.net/documentation/guides/getting-started)
