Question

我正在尝试从Google API中获取人员信息。

以下是代码

public static void main(String[] args) throws IOException, JSONException
{
    plus = new Plus.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, new HttpRequestInitializer() {
        public void initialize(HttpRequest request) throws IOException {
        }
    }).setApplicationName("youtubeSearchSample").build();

    Person profile = plus.people().get("https://www.googleapis.com/plus/v1/people/118359906569721392650?key=<Key>").execute();
    System.out.println("hello-->"+profile.toPrettyString());
}

public static Credential authorize(List<String> scopes, String credentialDatastore) throws IOException {

    // Load client secrets.
    InputStreamReader clientSecretReader = new InputStreamReader(Auth.class.getResourceAsStream("/client_secrets.json"));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, clientSecretReader);

    // Checks that the defaults have been replaced (Default = "Enter X here").
    if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
        System.out.println(
                "Enter Client ID and Secret from https://code.google.com/apis/console/?api=youtube"
                        + "into src/main/resources/client_secrets.json");
        System.exit(1);
    }

    // This creates the credentials datastore at ~/.oauth-credentials/${credentialDatastore}
    FileDataStoreFactory fileDataStoreFactory = new FileDataStoreFactory(new File(System.getProperty("user.home") + "/" + CREDENTIALS_DIRECTORY));
    DataStore<StoredCredential> datastore = fileDataStoreFactory.getDataStore(credentialDatastore);
    System.out.println("scopes-->"+scopes.toString());
    System.out.println("clientSecrets-->"+clientSecrets.toString());
    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
            HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, scopes).setCredentialDataStore(datastore)
            .build();

    // Build the local server and bind it to port 8080
    LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

    // Authorize.
    return new AuthorizationCodeInstalledApp(flow, localReceiver).authorize("user");
}

当我尝试运行上面的代码时，我遇到以下异常。

Exception in thread "main" java.lang.NoSuchMethodError: com.google.api.client.googleapis.services.json.AbstractGoogleJsonClient.<init>(Lcom/google/api/client/http/HttpTransport;Lcom/google/api/client/http/HttpRequestInitializer;Ljava/lang/String;Ljava/lang/String;Lcom/google/api/client/json/JsonObjectParser;Lcom/google/api/client/googleapis/services/GoogleClientRequestInitializer;Ljava/lang/String;Z)V
at com.google.api.services.plus.Plus.<init>(Plus.java:134)
at com.google.api.services.plus.Plus$Builder.build(Plus.java:2086)
at com.google.youtube.search.GoogleUserDetails.main(GoogleUserDetails.java:32)

我在为YouTube.Builder尝试过的时候，它工作得很好。

以下是我用于youtube builder的示例代码。

youtube = new YouTube.Builder(Auth.HTTP_TRANSPORT, Auth.JSON_FACTORY, new
HttpRequestInitializer() {
    public void initialize(HttpRequest request) throws IOException {
    }
}).setApplicationName("youtubeSearchSample").build();

我刚刚用Plus.Builder替换了YouTube.Builder，但我得到了上面提到的上述异常。

任何GoogleAPI专家都会让我犯错。

我通过更新pom.xml中的api库版本来修复此错误。

然后你应该打电话给

mvn clean package

您可以在Maven存储库中找到最新版本的Google库：

http://mvnrepository.com/artifact/com.googlecode.googleplus/google-plus-java-api
