通过 Google 站点 API 访问此 Google 站点时，我收到此异常消息。通过 Google Sites API 访问其他 Google Sites 时没有问题。

这是编程：

private static ContentFeed getFirstContentFeed(SitesService service, String siteName, Credential credential) throws Exception {
    // Configure URL as Google Sites content feed
    String url = String.format(                                                         
                        "%s/%s/%s",
                            GoogleOAuth2Constant.GOOG_SITES_CONTENT_FEED,
                            ReadXmlConfigurationService.getNode("domain"),
                            siteName);                                   

    // Assign Google credential into SitesService
    service.setOAuth2Credentials(credential);                                           
    // Use HTTP-SSL to call Google Sites API
    service.useSsl();                                                                   

    // Retrieve site contents
    return service.getFeed(new URL(url), ContentFeed.class);                            
}

此行导致抛出异常：

return service.getFeed(new URL(url), ContentFeed.class);

好吧，我不认为我的编程部分导致了这个问题，因为它以某种方式在重试后被调用。

是否通过添加 setConnectionTimeout() 解决了

private static ContentFeed getFirstContentFeed(SitesService service,
                                               String siteName,
                                               Credential credential) throws Exception {

    // Configure URL as Google Sites content feed
    String url = String.format(                                                         
                        "%s/%s/%s/",
                            GoogleOAuth2Constant.GOOG_SITES_CONTENT_FEED,
                            ReadXmlConfigurationService.getNode("domain"),
                            siteName);                                   

    // Assign Google credential into SitesService
    service.setOAuth2Credentials(credential);                                           
    // Use HTTP-SSL to call Google Sites API
    service.useSsl();
    // Set HTTP timeout for 2 minutes for larger feed
    service.setConnectTimeout(120000);

    // Retrieve site contents
    return service.getFeed(new URL(url), ContentFeed.class);                            
}
