我在使用服务帐户时遇到以下错误。 相同的代码在本地运行良好，并且我能够使用服务帐户创建凭据。

Answer 1

尝试以下...

1. 在 linux box 中设置代理。
2. 在创建存储时 - new NetHttpTransport() 提供您自己的方式来创建套接字并在传输中添加代理。

示例代码...

public HttpClient myHttpClient() throws Exception {

        SchemeRegistry schemeRegistry = new SchemeRegistry();
        //SetRegisrty for both HTTP and HTTPS - Check google for this.
        schemeRegistry.register(new Scheme("http", PlainSocketFactory
                .getSocketFactory(), YOUR_PROXY_PORT));
        schemeRegistry.register(new Scheme("https", SSLSocketFactory
                .getSocketFactory(), 443));

        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 30 * 1000);  // SET the timeout
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        ClientConnectionManager connManager = new ThreadSafeClientConnManager(
                params, schemeRegistry);
        DefaultHttpClient httpClient = new DefaultHttpClient(connManager,
                params);
        try {
            int proxyPort = YOUR_PROXY_PORT;
            String proxyHost = "YOUR_PROXT_HOST_NAME";
            if (proxyPort > 0 && proxyHost != null && proxyHost.length() > 0) {
                System.setProperty("https.proxyHost", proxyHost);
                System.setProperty("https.proxyPort", proxyPort + "");
                System.setProperty("http.proxyHost", proxyHost);
                System.setProperty("http.proxyPort", proxyPort + "");
                HttpHost proxy = new HttpHost(proxyHost, proxyPort);
                httpClient.getParams().setParameter(
                        ConnRoutePNames.DEFAULT_PROXY, proxy);
            }
        } catch (NullPointerException e) {
            System.out.println("Proxy error here");
        }
        return httpClient;
    }


    public static HttpTransport myNetHttpTransport()
                throws Exception {
            return new ApacheHttpTransport(myHttpClient());
        }

使用 .setTransport(myNetHttpTransport()) 而不是 NetHttpTransport() 。

我们在这上面花了很长时间。但截至目前，这似乎有效。如果有任何帮助，请告诉我...
