将代理与Google HTTP Client Library for Java结合使用 [英] Using proxies with Google HTTP Client Library for Java

问题描述

我使用Java的Google HTTP客户端库发出简单的JSON请求并解析响应.当我不通过代理时，它会很好地工作.但是现在我想允许我的用户在我的应用程序中使用代理(带有身份验证)功能.我查看了HttpTransport，HttpRequestFactory和HttpRequestInitializer类，但没有成功.

I use Google HTTP Client Library for Java to make simple JSON requests and parse responses. It works well when I don't go through a proxy. But now I'd like to allow my users to use a proxy (with authentication) functionality in my application. I looked in the HttpTransport, HttpRequestFactory and HttpRequestInitializer classes without any success.

到目前为止，我仅对示例进行了少量修改(并且大多数情况下，它正在删除不必要的代码).那么我在代码中的哪里添加代理设置?

I've only slightly modified the examples so far (and mostly it was removing unnecessary code). So where in the code do I add the proxy settings?

static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
static final JsonFactory JSON_FACTORY = new JacksonFactory();

<T> T get(String url, Class<T> type) throws IOException {
    HttpRequestFactory requestFactory =
            HTTP_TRANSPORT.createRequestFactory(new HttpRequestInitializer() {
                @Override
                public void initialize(HttpRequest request) {

                    request.setParser(new JsonObjectParser(JSON_FACTORY));
                }
            });
    HttpRequest request = requestFactory.buildGetRequest(new GenericUrl(url));
    return request.execute().parseAs(type);
}

推荐答案

对于使用google-http-client:1.13.1-beta

This seems to work just fine for an authenticated proxy using google-http-client:1.13.1-beta

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(PROXY_HOST, PROXY_PORT));
HttpTransport httpTransport = new NetHttpTransport.Builder().setProxy(proxy).build();

这还不足以满足您的需求吗?

Isn't this sufficient for your needs?
