Spring RestTemplate和代理身份验证
我正在尝试使用Spring进行REST调用。据我了解,正确的方法是使用RestTemplate
(?)。问题是,我在代理后面。
这是我现在的代码:
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();InetSocketAddress address = new InetSocketAddress(host, 3128);
Proxy proxy = new Proxy(Proxy.Type.HTTP, address);
factory.setProxy(proxy);
RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(factory);
看来可行,但是我需要在代理处进行身份验证,但是如何完成呢?该Proxy
类型以及该SimpleClientHttpRequestFactory
类型似乎都不处理凭据。没有凭证,我只会得到407
…
回答:
经过许多不同的选择之后,由于能够在创建时为RestTemplate设置代理,因此我可以选择以下代码,因此我可以将其重构为单独的方法。只是要注意,它还具有其他依赖性,因此请记住这一点。
private RestTemplate createRestTemplate() throws Exception { final String username = "myusername";
final String password = "myPass";
final String proxyUrl = "proxy.nyc.bigtower.com";
final int port = 8080;
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(proxyUrl, port),
new UsernamePasswordCredentials(username, password)
);
HttpHost myProxy = new HttpHost(proxyUrl, port);
HttpClientBuilder clientBuilder = HttpClientBuilder.create();
clientBuilder.setProxy(myProxy).setDefaultCredentialsProvider(credsProvider).disableCookieManagement();
HttpClient httpClient = clientBuilder.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setHttpClient(httpClient);
return new RestTemplate(factory);
}
//我使用的依赖项
