增加google Analytics API Read timed out，将java代码转换为coldfusion

Question

小问题：如何将以下 java 代码转换为 ColdFusion 代码？

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
        }};

 }

说明： 我使用一个组件与谷歌分析 API 进行通信。这很好用，但有时会发生读取超时。我想增加连接并读取超时。我在 StackOverflow 上找到了一篇文章，解释了如何在 Java 中执行此操作 (https://stackoverflow.com/a/30721185/2482184)。但是，我无法将 java 代码转换为 ColdFusion 代码。在我目前用于与 Google Analytics API 通信的 ColdFusion 组件下方：

解释如何增加连接和读取超时的java代码：

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();
  }

如果我理解正确，我需要修改这行代码：

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

类似于：

<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() />

然而，我还没有成功地将 java setHttpTimeout 函数转换为coldfusion。任何帮助将不胜感激。

要创建 3 分钟的请求超时，您可以在发出 http 请求之前调用这行代码。

标签格式

<cfsetting RequestTimeout = 3 * 60>

CFScript 格式

setting requesttimeout = 3 * 60;
