I am developing a piece of code which can create and download reports using Google DFA Reporting API's.

I am able to do the same using Client Id and Client Secret, which is generated using Install-App (native Application) account, but with this type of account, it always open a browser for first time and then only it authenticates the future request.

On further reading, I came across the service account. I then created a new Service Account and downloaded p12 key. I am now able to build credential object with the help of p12 and Email account (*******ccms@developer.gserviceaccount.com). I can confirm this as I am seeing access token in a credential object after calling credentials.refreshToken().

I then create an object of DFA Reporting using the above credential and trying to fetch profiles list, but I am getting the below error:

java.lang.IllegalArgumentException: No profiles found
    at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:92)
    at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:49)
    at com.google.api.services.samples.dfareporting.cmdline.GetAllUserProfiles.list(GetAllUserProfiles.java:52)
    at com.google.api.services.samples.dfareporting.cmdline.DfaReportingSample.main(DfaReportingSample.java:171)

Please see my code below and let me know where I am going wrong:

private static Credential authorize() throws Exception {
    // load client secrets

    List<String> SCOPES = ImmutableList
            .of("https://www.googleapis.com/auth/dfareporting");
    String SERVICE_ACCOUNT_EMAIL = "*************************@developer.gserviceaccount.com";

    String Path = DfaReportingSample.class.getResource(
            "/TestDFA-5d985ff38b34.p12").getPath();
    java.io.File file = new java.io.File(Path);

    HttpTransport httpTransport = new NetHttpTransport();
    JacksonFactory jsonFactory = new JacksonFactory();

    Credential credentials =  new GoogleCredential.Builder()
            .setTransport(httpTransport)
            .setJsonFactory(jsonFactory)
            .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
            .setServiceAccountScopes(SCOPES)
            .setServiceAccountPrivateKeyFromP12File(file).build();

    credentials.refreshToken();

    return credentials;
}

private static Dfareporting initializeDfareporting() throws Exception {
    Credential credential = authorize();

    // Create DFA Reporting client.
    return new Dfareporting(httpTransport, JSON_FACTORY, credential);
}


public static void main(String[] args) {

    try {
        httpTransport = GoogleNetHttpTransport.newTrustedTransport();
        Dfareporting reporting = initializeDfareporting();

        UserProfiles up = reporting.userProfiles();
        List l = up.list();
        UserProfileList profiles = l.execute();
        // {"etag":"\"bM2H6qONz9kIDiByk_eTdC6Ehcc/vyGp6PvFo4RvsFtPoIWeCReyIC8\"","items":[],"kind":"dfareporting#userProfileList"}
        Preconditions.checkArgument(
            profiles.getItems() != null && !profiles.getItems().isEmpty(), "No profiles found");
        for (UserProfile userProfile : profiles.getItems()) {
          System.out.printf("User profile with ID \"%s\" and name \"%s\" was found.%n",
              userProfile.getProfileId(), userProfile.getUserName());
        }
....................................

PS: I am able to fetch all the profiles, if I use access token which is generated using client id and client secret provided by native application (installed apps) account.

Thanks, Hussain Bohra

在使用服务帐户（和 p12 密钥）进行了很多尝试后，我们无法使其与 Google DFA 报告一起使用。因此，我们现在使用以下类进行身份验证：

com.google.api.ads.common.lib.auth.OfflineCredentials

input = new FileInputStream(Utils.getProperty(Constants.HOME_PATH)
        + Utils.getProperty(Constants.CLIENT_SECRETS_DIRECTORY)
        + Constants.PATH_SEPARATOR + userPropertyFile);
userProperty.load(input);

credential = new OfflineCredentials.Builder()
        .forApi(OfflineCredentials.Api.DFA)
        .withHttpTransport(
                GoogleNetHttpTransport.newTrustedTransport())
        .withClientSecrets(userProperty.getProperty("client_id"),
                userProperty.getProperty("client_secret"))
        .withRefreshToken(userProperty.getProperty("refresh_token"))
        .build().generateCredential();

上述代码中使用的刷新令牌是为每个帐户手动生成的（一次处理）。使用此凭证对象，我们现在能够在 DFA 报告中执行以下所有活动： - 列出配置文件 - 验证和创建报告 - 下载报告数据。

获取刷新令牌的代码（涉及在浏览器中单击接受的手动步骤）

java.io.File DATA_STORE_DIR = new java.io.File(
        "d:/dfa-reporting/.store/dfareporting_sample");
FileDataStoreFactory dataStoreFactory;
dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);

GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(
        JSON_FACTORY,
        new InputStreamReader(DfaReportingSample.class
                .getResourceAsStream("/client_secret_galtieri.json")));
// set up authorization code flow
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
        httpTransport, JSON_FACTORY, clientSecrets, SCOPES)
        .setDataStoreFactory(dataStoreFactory).build();
// authorize
String refreshToken = new AuthorizationCodeInstalledApp(flow,
        new PromptReceiver()).authorize("hbohra").getRefreshToken();

谢谢，侯赛因·博拉
