How to use

setProxy

method

in

com.microsoft.azure.storage.OperationContext

  public static void setProxy(final OperationContext operationContext, final ProcessContext processContext) {
    final ProxyConfiguration proxyConfig = ProxyConfiguration.getConfiguration(processContext);
    operationContext.setProxy(proxyConfig.createProxy());
  }
}

context.setProxy(socksProxy);
break;
context.setProxy(httpProxy);
break;

@Test

  OperationContext opContext = new OperationContext();
  opContext.setProxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.1.1.1", 8888)));
  // Turn of retries to make the failure happen faster
  BlobRequestOptions opt = new BlobRequestOptions();
  opt.setRetryPolicyFactory(new RetryNoRetry());
  // Unfortunately HttpURLConnection doesn't expose a getter and the usingProxy method it does have doesn't
  // work as one would expect and will always for us return false. So, we validate by making sure the request
  // fails when we set a bad proxy rather than check the proxy setting itself.
