如何在执行元的同一线程中获取http.singleRequest(httpRequest)的Httpresponse？

import okhttp3.*;

import java.util.concurrent.CompletableFuture;

public class AsyncHttpClientWithFutureExample {
    public static void main(String[] args) {
        OkHttpClient client = new OkHttpClient.Builder().build();

        Request request = new Request.Builder()
                .url("http://example.com")
                .build();

        CompletableFuture<String> future = new CompletableFuture<>();

        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                future.completeExceptionally(e);
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

                future.complete(response.body().string());
            }
        });

        // 在这里你可以做一些其他的操作，而不需要等待HTTP响应
        // 当你需要响应时，可以调用future.get()来获取结果
        try {
            String responseBody = future.get();
            System.out.println(responseBody);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
