无法从 Google Analytics 获取数据（401 Unauthorized）

Question

我尝试实现基本的数据馈送示例，我得到的只是：

com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized.

但是当我使用http://code.google.com/apis/analytics/docs/gdata/gdataExplorer.html
它适用于我的 Google Analytics 帐户。

看来我已经按照 OAuth2 说明完成了所有操作：创建了客户端 ID 和客户端密码，启用了 Analytcs API。

我还尝试使用 Analytics Management API 获取我的个人资料和帐户，但我遇到了同样的错误。我做错了什么？

这是我的代码（当然，我使用实际的 CLIENT_ID、CLIENT_SECRET 和 TABLE_ID 运行此代码）：

public class AnalyticsTest {

    private static final String CLIENT_ID = "MY_CLIENT_ID";
    private static final String CLIENT_SECRET = "MY_CLIENT_SECRET";
    private static final String REDIRECT_URL = "urn:ietf:wg:oauth:2.0:oob";
    private static final String APPLICATION_NAME = "test";
    private static final String SCOPE = "https://www.googleapis.com/auth/analytics";
// TRIED AS WELL private static final String SCOPE = "https://www.google.com/analytics/feeds";
    private static final String TABLE_ID = "MY_TABLE_ID";

    public static void main(String[] args) throws IOException {
            NetHttpTransport netHttpTransport = new NetHttpTransport();
            JacksonFactory jacksonFactory = new JacksonFactory();
            // Generate the URL to send the user to grant access.
            String authorizationUrl = new GoogleAuthorizationRequestUrl(CLIENT_ID, REDIRECT_URL, SCOPE).build();

            // Direct user to the authorization URI.
            System.out.println("Go to the following link in your browser:");
            System.out.println(authorizationUrl);

            // Get authorization code from user.
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
            System.out.println("What is the authorization code?");
            String authorizationCode = null;
            authorizationCode = in.readLine();

            // Use the authorization code to get an access token and a refresh
            // token.
            AccessTokenResponse response = null;
            try {
                    response = new GoogleAccessTokenRequest.GoogleAuthorizationCodeGrant(netHttpTransport, jacksonFactory, CLIENT_ID, CLIENT_SECRET, authorizationCode, REDIRECT_URL).execute();
            } catch (IOException ioe) {
                    ioe.printStackTrace();
            }

            // Use the access and refresh tokens to get a new
            // GoogleAccessProtectedResource.
            GoogleAccessProtectedResource googleAccessProtectedResource = new GoogleAccessProtectedResource(response.accessToken, netHttpTransport, jacksonFactory, CLIENT_ID, CLIENT_SECRET, response.refreshToken);

            Analytics analytics = Analytics
                            .builder(netHttpTransport, jacksonFactory)
                            .setHttpRequestInitializer(googleAccessProtectedResource)
                            .setApplicationName(APPLICATION_NAME).build();
            //System.out.println(analytics.management().accounts().list().execute());

            Get apiQuery = analytics.data().ga().get(TABLE_ID, // "ga:" + Profile
                            // Id.
                            "2011-09-01", // Start date.
                            "2011-12-23", // End date.
                            "ga:visits"); // Metrics.

            try {
                    GaData gaData = apiQuery.execute();
                    // Success. Do something cool!

            } catch (GoogleJsonResponseException e) {
                    // Catch API specific errors.
                    e.printStackTrace();

            } catch (IOException e) {
                    // Catch general parsing errors.
                    e.printStackTrace();
            }

    } 

这是堆栈跟踪：

com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized
{
“代码”：401，
“错误”：[ {
“域”：“全球”，
"位置" : "授权",
“位置类型”：“标题”，
“消息”：“无效凭据”，
“原因”：“authError”
} ],
“消息”：“无效凭据”
}
在 com.google.api.client.googleapis.json.GoogleJsonResponseException.from(GoogleJsonResponseException.java:138)
在 com.google.api.client.googleapis.services.GoogleClient.execute(GoogleClient.java:123)
在 com.google.api.client.http.json.JsonHttpRequest.executeUnparsed(JsonHttpRequest.java:67)
在 com.google.api.services.analytics.Analytics$Data$Ga$Get.execute(Analytics.java:1335)
在 voc.AnalyticsTest.main(AnalyticsTest.java:76)

尝试从这里更改您的范围：

private static final String SCOPE = "https://www.googleapis.com/auth/analytics";

到这里：

private static final String SCOPE = "https://www.googleapis.com/auth/analytics.readonly";
