Spring RestTemplate and Proxy Auth
提问by yogiginger
I'm trying to do REST calls with Spring. As I understand, the right way to go is using RestTemplate(?). Problem is, I'm behind a proxy.
我正在尝试使用 Spring 进行 REST 调用。据我了解，正确的做法是使用RestTemplate(?)。问题是，我支持代理。
This is my code right now:
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);
It seems to work, but I need to authenticate at the proxy, but how is this done? The Proxytype as well as the SimpleClientHttpRequestFactorytype don't seem to handle credentials. Without credentials, I'm getting just 407...
它似乎有效，但我需要在代理上进行身份验证，但这是如何完成的？该Proxy类型以及该SimpleClientHttpRequestFactory类型似乎不处理凭据。没有凭据，我只会收到 407 ...

After quite a few different options I settled on The below code due to the ability to set the proxy for the RestTemplate at creation so I could refactor it into a separate method. Just to note it also has an additional dependency so keep that in mind.
由于能够在创建时为 RestTemplate 设置代理，因此我选择了以下代码，因此我可以将其重构为一个单独的方法。请注意，它还有一个额外的依赖项，所以请记住这一点。
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);
}

the code below worked for me.
下面的代码对我有用。
RestTemplate restTemplate = new RestTemplate();
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials( new AuthScope("proxyHost", "proxyPort"), new UsernamePasswordCredentials("proxyUser", "proxyPass") );
HttpClientBuilder clientBuilder = HttpClientBuilder.create();
clientBuilder.useSystemProperties();
clientBuilder.setProxy(new HttpHost("proxyHost", "proxyPort"));
clientBuilder.setDefaultCredentialsProvider(credsProvider);
clientBuilder.setProxyAuthenticationStrategy(new ProxyAuthenticationStrategy());
CloseableHttpClient client = clientBuilder.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setHttpClient(client);
restTemplate.setRequestFactory(factory);
