okhttp 未在 logcat 中显示消息

Question

我正在尝试以下代码中的 OkHttp 个示例我期待一些打印消息，但是我没有收到任何东西，你能告诉我为什么吗？

private final OkHttpClient client = new OkHttpClient();

public void run() throws Exception {
    Request request = new Request.Builder()
            .url("http://publicobject.com/helloworld.txt")
            .build();

    Response response = client.newCall(request).execute();
    if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);

    Headers responseHeaders = response.headers();
    for (int i = 0; i < responseHeaders.size(); i++) {
        System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
    }

    System.out.println(response.body().string());
}

这是logcat

正如我评论的那样，请尝试以下代码：

    private class VoidRequest extends AsyncTask<Void, Void, Void> {
        @Override
        protected Void doInBackground(Void... voids) {
            MyOkHttpRequest request = new MyOkHttpRequest();
            try {
                request.run();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }
    }

    public class MyOkHttpRequest {
        private OkHttpClient client = new OkHttpClient();
        public void run() throws IOException {
            Request request = new Request.Builder()
                    .url("http://publicobject.com/helloworld.txt")
                    .build();
            Response response = client.newCall(request).execute();
            if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
            Headers responseHeaders = response.headers();
            for (int i = 0; i < responseHeaders.size(); i++) {
                System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
            }
            System.out.println(response.body().string());
        }
    }

然后在onCreate()中调用new VoidRequest().execute();

okhttp 未在 logcat 中显示消息

okhttp not displaying message in logcat
