google Analytics APIの読み取りがタイムアウトし、Javaコードをcoldfusionに変換する

Dec 23 2020

簡単な質問:次のJavaコードをColdFusionコードに変換するにはどうすればよいですか?

private static HttpRequestInitializer setHttpTimeout(final HttpRequestInitializer requestInitializer) {
      return new HttpRequestInitializer() {
        @Override
        public void initialize(HttpRequest httpRequest) throws IOException {
          requestInitializer.initialize(httpRequest);
          httpRequest.setConnectTimeout(3 * 60000);  // 3 minutes connect timeout
          httpRequest.setReadTimeout(3 * 60000);  // 3 minutes read timeout
        }};

 }

説明:コンポーネントを使用して、Google AnalyticsAPIと通信します。これはうまく機能しますが、読み取りタイムアウトが発生する場合があります。接続を増やしてタイムアウトを読み取りたいのですが。Javaでこれを行う方法を説明するStackOverflowの投稿をここで見つけました(https://stackoverflow.com/a/30721185/2482184)。ただし、JavaコードをColdFusionコードに変換するのに問題があります。現在GoogleAnalyticsAPIとの通信に使用しているColdFusionコンポーネントの下:

接続を増やしてタイムアウトを読み取る方法を説明するJavaコード:

private static HttpRequestInitializer setHttpTimeout(final HttpRequestInitializer requestInitializer) {
      return new HttpRequestInitializer() {
        @Override
        public void initialize(HttpRequest httpRequest) throws IOException {
          requestInitializer.initialize(httpRequest);
          httpRequest.setConnectTimeout(3 * 60000);  // 3 minutes connect timeout
          httpRequest.setReadTimeout(3 * 60000);  // 3 minutes read timeout
        }};

 }

public static Analytics initializeAnalytics() throws Exception {
    // Initializes an authorized analytics service object.

    // Construct a GoogleCredential object with the service account email
    // and p12 file downloaded from the developer console.
    HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
    GoogleCredential credential = new GoogleCredential.Builder()
        .setTransport(httpTransport)
        .setJsonFactory(JSON_FACTORY)
        .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
        .setServiceAccountPrivateKeyFromP12File(new File(KEY_FILE_LOCATION))
        .setServiceAccountScopes(AnalyticsScopes.all())
        .build();

    // Construct the Analytics service object.
    return new Analytics.Builder(httpTransport, JSON_FACTORY,setHttpTimeout(credential))
        .setApplicationName(APPLICATION_NAME).build();
  }

正しく理解している場合は、次のコード行を変更する必要があります。

<cfset variables.analytics = variables.Analytics_Builder
    .setApplicationName(variables.analyticsAppName)
    .setHttpRequestInitializer(local.credential)
    .build() />

次のようなものに:

<cfset variables.analytics = createObject("java",
    "com.google.api.services.analytics.Analytics$Builder").init(
        variables.HTTP_Transport, 
        variables.JSON_Factory, 
        setHttpTimeout(local.credential)
    )
    .setApplicationName(variables.analyticsAppName)
    .setHttpRequestInitializer(local.credential)
    .build() />

Howerer私はjavasetHttpTimeout関数をcoldfusionにカバーすることに成功していません。どんな助けでも大歓迎です。

3分のリクエストタイムアウトを作成するには、httpリクエストを行う前にこのコード行を呼び出すことができます。

タグ形式

<cfsetting RequestTimeout = 3 * 60>

CFScript形式

setting requesttimeout = 3 * 60;
