okhttpclient入口的假期

Question

使用OkhttpClient，我可以做以下操作，这将使我在可能的情况下发送请求并处理响应。

okhttpClient
    .newCall(request)
    .enqueue(
        new Callback() {

          @Override
          public void onResponse(Call arg0, Response arg1) throws IOException {
            log.info("Call success", arg1);
          }

          @Override
          public void onFailure(Call arg0, IOException arg1) {
            log.info("Call fail", arg1);
          }
        });

有没有办法用假装来做到这一点？如果有帮助，我已经启用了okhttpclient进行假装吗？

Answer 1

See https://github.com/OpenFeign/feign#async-execution-via -completableFuture

interface GitHub {
  @RequestLine("GET /repos/{owner}/{repo}/contributors")
  CompletableFuture<List<Contributor>> contributors(@Param("owner") String owner, @Param("repo") String repo);
}

public class MyApp {
  public static void main(String... args) {
    GitHub github = AsyncFeign.asyncBuilder()
                         .decoder(new GsonDecoder())
                         .target(GitHub.class, "https://api.github.com");

由于其OKHTTP客户端不是异步，您要么需要使用

asyncclient.asyncclient（client，executorService），要么更优化地实现Okhttpasyncclient。

或rx

public interface GitHubReactiveX {
      
  @RequestLine("GET /repos/{owner}/{repo}/contributors")
  Flowable<Contributor> contributors(@Param("owner") String owner, @Param("repo") String repo);
  
  class Contributor {
    String login;
    
    public Contributor(String login) {
      this.login = login;
    }
  }
}

public class ExampleRxJava2 {
  public static void main(String args[]) {
    GitHubReactiveX gitHub = RxJavaFeign.builder()      
      .target(GitHub.class, "https://api.github.com");
    
    List<Contributor> contributors = gitHub.contributors("OpenFeign", "feign")
      .collect(Collectors.toList())
      .block();
  }
}
