英文:
Add Proxy to HttpRequest in java
问题
以下是翻译好的部分：
我正在尝试理解如何在使用Java API时为每个请求实现类似以下代码的代理：
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.version(HttpClient.Version.HTTP_2)
.uri(URI.create("https://myurl"))
.timeout(Duration.ofMinutes(2))
.setHeader("User-Agent","Just an user agent")
.GET()
.build();
HttpResponse<String> response = client.send(request,
HttpResponse.BodyHandlers.ofString());
我从文档中看到（https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpClient.html#Asynchronous%20Example）
可以在“同步”请求中实现。我的代码位于一个方法中，将在多个线程中并行运行。那么如何在“异步请求”中设置代理？如果不可能的话，它们之间有什么区别？
英文:
I'm trying to understand how can I implement the use of a proxy for each request built like the following using Java API:
HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
.version(HttpClient.Version.HTTP_2)
.uri(URI.createh("https://myurl"))
.timeout(Duration.ofMinutes(2))
.setHeader("User-Agent","Just an user agent")
.GET()
.build();
HttpResponse<String> response = client.send(request,
HttpResponse.BodyHandlers.ofString());
I'm seeing from the doc (https://docs.oracle.com/en/java/javase/11/docs/api/java.net.http/java/net/http/HttpClient.html#Asynchronous%20Example)
that is possible with Synchronous requests. My code is within a method and it will run with threads parallelly. So how is it possible to set a proxy with Asynchronous Requests? If it is not possible, what's the difference between them?

解决了，关于这一点文档不太清楚，但最终我能够在构建客户端时设置代理：
HttpClient client = HttpClient.newBuilder()
.proxy(ProxySelector.of(new InetSocketAddress("proxy", port)))
.build();
// 请求代码与我上面写的完全相同。
该方法是 newBuilder，而不是 Builder。
英文:
Solved, it's a bit unclear the doc about that but at the end, I was able to set the proxy when building the client:
HttpClient client = HttpClient.newBuilder().
proxy(ProxySelector.of(new InetSocketAddress("proxy",port))))
.build();
//The request code is identical to what I wrote above.
The method is newBuilder anyway and not Builder.
