Java 如何使用OkHttp'；有请求的HttpUrl？

我有一个http url：

HttpUrl httpurl = new HttpUrl.Builder()
.scheme("https")
.host("www.google.com")
.addPathSegment("search")
.addQueryParameter("q", "polar bears")
.build();

如何将其用于请求？也就是说，如何向由

httpurl

构造的url发送请求？

使用：

然后按此操作。

尝试以下操作：

Request request = new Request.Builder()
            .method(method, requestBody)
            .url(httpurl)
            .addHeader(headerName, headerValue);
            .build();

OkHttpClient client = new OkHttpClient();
client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Request request, IOException e) {

    }

    @Override
    public void onResponse(Response response) throws IOException {

    }
});

Request request = new Request.Builder()
            .method(method, requestBody)
            .url(httpurl)
            .addHeader(headerName, headerValue);
            .build();

OkHttpClient client = new OkHttpClient();
client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Request request, IOException e) {

    }

    @Override
    public void onResponse(Response response) throws IOException {

    }
});
