传参数问题

[tanzhixue]

请问下面这种的该如何实现呢？ Request.Builder builder = new Request.Builder();

    builder.addHeader("lang", BaseApplication.lang)
            .addHeader("deviceId", Configs.deviceName);
    FormBody formBody = new FormBody.Builder()
            .add("menuId", menuId)
            .build();
    builder.post(formBody);

Request request = builder.url(url).build();
