[英]Oauth 2.0 with grant_type=client_credentials?
I am looking for a OAuth 2.0 client in Java which supports machine to machine communication via grant_type=client_credentials
.我正在寻找 Java 中的 OAuth 2.0 客户端,它支持通过grant_type=client_credentials
进行机器对机器通信。 Any recommendations?有什么建议吗?
Edit : I am asking here, since 2 days of research indicate so far, that there are many libs for OAuth 2.0, but none seems to support the required mode of operation.编辑:我在这里问,因为到目前为止 2 天的研究表明,有许多用于 OAuth 2.0 的库,但似乎没有一个支持所需的操作模式。
After many headaches, I finally found that ScribeJava supports the needed mode of operations – although it's somewhat hidden.经过多次头疼,我终于发现 ScribeJava 支持所需的操作模式——尽管它有些隐藏。
Here is my adopted version:这是我采用的版本:
public static void main(String... args) throws IOException, InterruptedException, ExecutionException {
// Replace these with your client id and secret
final String clientId = "your client id";
final String clientSecret = "your client secret";
final OAuth20Service service = new ServiceBuilder(clientId)
.apiSecret(clientSecret)
.defaultScope("any") // replace with desired scope
.build(new DefaultApi20() {
@Override
public String getAccessTokenEndpoint() {
return "http://127.0.0.1:8082/token";
}
@Override
protected String getAuthorizationBaseUrl() {
throw new UnsupportedOperationException(
"This API doesn't support a Base URL.");
}
});
System.out.println("=== " + NETWORK_NAME + "'s OAuth Workflow ===");
System.out.println();
final OAuth2AccessToken accessToken = service.getAccessTokenClientCredentialsGrant();
System.out.println("Got the Access Token!");
System.out.println(accessToken.getRawResponse());
System.out.println();
System.out.println("Thats it man! Go and build something awesome with ScribeJava! :)");
}
