Google Indexing API 请求批处理 在 Java 中

Question

我有谷歌索引API问题。我是初级开发人员。T.T

我正在使用Java源代码中的索引API。当前 API 调用已成功为一个站点（无批处理）的请求编制索引。但我不能做请求批处理。

https://developers.google.com/api-client-library/java/google-api-java-client/batch

不要遵循首页上的示例源。页面太差，无法解释。

https://productforums.google.com/forum/#!topic/webmasters/L6yVB7iq1os;context-place=topicsearch/indexing$20api$20request$20batch

上面页面上的示例来源答案也是相同的。

上面的源找不到插入方法。你可以帮我吗？

以下是我的消息来源。

您需要使用client.urlNotifications().publish(unf).queue(batch, callback);而不是插入。工作代码示例供您参考。

private static void requestBatchIndex(List<String> urls) throws Exception {
    String scopes = "https://www.googleapis.com/auth/indexing";
    String endPoint = "https://indexing.googleapis.com/v3/urlNotifications:publish";
    JsonFactory jsonFactory = new JacksonFactory();
    HttpTransport httpTransport = new NetHttpTransport();
    // service_account_file.json is the private key that you created for
    // your service account.
    InputStream in = FileUtils.openInputStream(new File("src/main/resources/service_account_file.json"));
    GoogleCredential credentials = GoogleCredential.fromStream(in, httpTransport, jsonFactory).createScoped(Collections.singleton(scopes));
    JsonBatchCallback<PublishUrlNotificationResponse> callback = new JsonBatchCallback<PublishUrlNotificationResponse>() {
        public void onSuccess(PublishUrlNotificationResponse res, HttpHeaders responseHeaders) {
            try {
                System.out.println(res.toPrettyString());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        public void onFailure(GoogleJsonError e, HttpHeaders responseHeaders) {
            System.out.println("Error Message: " + e.getMessage());
        }
    };
    IndexingRequestInitializer iri = new IndexingRequestInitializer();
    Indexing client = new Indexing(httpTransport, jsonFactory, credentials);
    BatchRequest batch = client.batch();
    batch.setBatchUrl(new GenericUrl("https://indexing.googleapis.com/batch"));
    for (String url : urls) {
        UrlNotification unf = new UrlNotification();
        unf.setUrl(url);
        unf.setType("URL_UPDATED");
        client.urlNotifications().publish(unf).queue(batch, callback);
    }
    batch.execute();
}
