如何在异步调用和回调中使用OKHttp？

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:4.9.1'
}

OkHttpClient client = new OkHttpClient();

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

client.newCall(request).enqueue(new Callback() {
    @Override
    public void onFailure(Call call, IOException e) {
        // 请求失败处理逻辑
    }

    @Override
    public void onResponse(Call call, Response response) throws IOException {
        // 请求成功处理逻辑
        String responseData = response.body().string();
        // 处理返回的数据
    }
});
