Question

我有一个spring-boot个应用，我可以向HTTP发出请求，并会向互联网上的其他资源发送另一个HTTP请求。

@RestController
@SpringBootApplication
public class BookApplication {

  @RequestMapping(value = "/available")
  public String available() throws Exception {

    String url = "https://www.google.com";

    URL obj = new URL(url);
    HttpURLConnection con = (HttpURLConnection) obj.openConnection();

    con.setRequestMethod("GET");
    con.setRequestProperty("User-Agent", "Mozilla/5.0");
    BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
    StringBuffer response = new StringBuffer();
    String inputLine;

    while ((inputLine = in.readLine()) != null) {
      response.append(inputLine);
    }
    in.close();
    return "Spring in Action";
  }

  public static void main(String[] args) {
    SpringApplication.run(BookApplication.class, args);
  }
}

我还有另一个spring-boot个Zuul代理的应用。

@EnableZuulProxy
@SpringBootApplication
public class GatewayApplication {

  public static void main(String[] args) {
    SpringApplication.run(GatewayApplication.class, args);
  }

  @Bean
  public SimpleFilter simpleFilter() {
    return new SimpleFilter();
  }
}

SimpleFilter类是：

public class SimpleFilter extends ZuulFilter {

  private static Logger log = LoggerFactory.getLogger(SimpleFilter.class);

  @Override
  public String filterType() {
    return "pre";
  }

  @Override
  public int filterOrder() {
    return 1;
  }

  @Override
  public boolean shouldFilter() {
    return true;
  }

  @Override
  public Object run() {
    RequestContext ctx = RequestContext.getCurrentContext();
    HttpServletRequest request = ctx.getRequest();

    log.info(String.format("%s request to %s", request.getMethod(), request.getRequestURL().toString()));

    return null;
  }

}

Zuul代理应用的application.properties：

zuul.routes.books.url=http://localhost:8090

ribbon.eureka.enabled=false

server.port=8080

基本上，一切都来自本教程tutorial

所以我想知道是否有机会将请求代理到“https://www.google.com”由/available中的BookApplication资源完成？

Answer 1

没有办法做到这一点。 Zuul并不适合那种事情。

有没有办法使用Zuul代理内部http调用？
