HttpClient.Builder Sınıfı - HttpClient API

connectTimeout metodu

 Açıklaması şöyle

The Java 11 HTTP Client API allows developers to configure timeouts for their HTTP requests. This is particularly useful when dealing with scenarios where a response is expected within a certain time frame. By setting appropriate timeout values, applications can avoid waiting indefinitely for a response and gracefully handle timeout scenarios.

Örnek

Şöyle yaparız. 

HttpClient client = HttpClient.newBuilder()
    .connectTimeout(Duration.ofSeconds(10))
    .build();

Örnek

Şöyle yaparız

HttpClient httpClient = HttpClient.newBuilder()
  .version(HttpClient.Version.HTTP_2)
  .connectTimeout(Duration.ofSeconds(20))
  .build();

HttpRequest httpRequest = HttpRequest.newBuilder()
  .GET()
  .uri(URI.create("https://..."))
  .build();

HttpResponse httpResponse = httpClient.send(httpRequest, 
  HttpResponse.BodyHandlers.ofString());

System.out.println(httpResponse.body());

followRedirects metodu

Açıklaması şöyle

The Java 11 HTTP Client API simplifies the handling of redirects in HTTP requests. By default, the API automatically follows redirects, allowing developers to easily handle scenarios where the requested resource has been moved or requires authentication. The API also provides options to control the behavior of redirects, such as maximum follow limit and redirect policy customization.

Örnek

Redirect.NORMAL şu anlama gelir

Always redirect, except from HTTPS URLs to HTTP URLs.

Şöyle yaparız. 

HttpClient client = HttpClient.newBuilder()
    .followRedirects(Redirect.NORMAL)
    .build();

proxy metodu

Açıklaması şöyle

The Java 11 HTTP Client API supports working with proxies, enabling applications to route their HTTP requests through a proxy server. Developers can configure the API to use a specific proxy server, provide authentication credentials if required, and handle scenarios where multiple proxy servers are available.

Örnek

Şöyle yaparız

import java.net.ProxySelector;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
 
HttpClient HTTP_CLIENT = HttpClient.newBuilder()
   // default
  .version(HttpClient.Version.HTTP_2)
  // Always redirect, except from HTTPS URLs to HTTP URLs.
  .followRedirects(HttpClient.Redirect.NORMAL) 
  .proxy(ProxySelector.getDefault())
  .build();

Örnek

Şöyle yaparız. 

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.example.com", 8080));

HttpClient client = HttpClient.newBuilder()
    .proxy(proxy)
    .build();
