SpringRestAPI通过另一个RESTAPI进行身份验证

您的代码将如下所示:

String path = System.getProperty("user.home") + "/.stormpath/apiKey.properties";
String applicatiOnUrl= "https://api.stormpath.com/v1/applications/2TqboZ1qo73eDM4gTo2H94";
Client client = Clients.builder().setApiKey(ApiKeys.builder().setFileLocation(path).build()).build();
Application application = client.getResource(applicationUrl, Application.class);

public String getAccessToken(ApiKey apiKey) {
    HttpRequest request = createOauthAuthenticationRequest(apiKey);
    AccessTokenResult accessTokenResult = (AccessTokenResult) application.authenticateApiRequest(request);
    System.out.println(accessTokenResult.getScope());
    return accessTokenResult.getTokenResponse().getAccessToken();
}

public boolean startEngines(String accessToken) {
    HttpRequest request = createRequestForOauth2AuthenticatedOperation(accessToken);
    try {
        OauthAuthenticationResult result = application.authenticateOauthRequest(request).execute();
        System.out.println(result.getAccount().getEmail() + " is about to start the engines!");

        doStartEngines(); //Here you will actually call your internal doStartEngines() operation
        return true;

    } catch (AccessTokenOauthException e) {

        //This accessToken is not allowed to start the engines
        System.out.print("AccessToken: " + accessToken + " just tried to start the engines. He is not allowed to do so.");
        return false;

    }
}

private HttpRequest createOauthAuthenticationRequest(ApiKey apiKey) {
    try {
        String credentials = apiKey.getId() + ":" + apiKey.getSecret();

        Map headers = new LinkedHashMap();
        headers.put("Accept", new String[]{"application/json"});
        headers.put("Content-Type", new String[]{"application/x-www-form-urlencoded"});
        headers.put("Authorization", new String[]{"Basic " + Base64.encodeBase64String(credentials.getBytes("UTF-8"))});

        Map parameters = new LinkedHashMap();
        parameters.put("grant_type", new String[]{"client_credentials"});

        HttpRequest request = HttpRequests.method(HttpMethod.POST)
                .headers(headers)
                .parameters(parameters)
                .build();
        return request;
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

private HttpRequest createRequestForOauth2AuthenticatedOperation(String token) {
    try {
        Map headers = new LinkedHashMap();
        headers.put("Accept", new String[]{"application/json"});
        headers.put("Authorization", new String[]{"Bearer " + token});
        HttpRequest request = HttpRequests.method(HttpMethod.GET)
                .headers(headers)
                .build();
        return request;
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

private void doStartEngines() {
    System.out.println("Server-side message: Engines started!!!");
}
