### 本番環境

本番環境では、React、Vue.js、Angularなどの最新のフレームワークで作成されたフロントエンドを使用しているでしょう。

        RequestData data = RequestDataBuilder.newRequestData().url(null).build();

        assertNull(data.getUrl());
    }

    public void test_realWorldUsageExample1() {
        // Real-world example: crawling a web page
        RequestData data = RequestDataBuilder.newRequestData().get().url("https://example.com/article/12345").weight(1.0f).build();

        assertNotNull(data);
        assertEquals(Method.GET, data.getMethod());

OkHttp depends on [Okio][okio] for high-performance I/O and the [Kotlin standard library][kotlin]. Both are small libraries with strong backward-compatibility.

We highly recommend you keep OkHttp up-to-date. As with auto-updating web browsers, staying current
with HTTPS clients is an important defense against potential security problems. [We
track][tls_history] the dynamic TLS ecosystem and adjust OkHttp to improve connectivity and
security.
