Projek yang saya sedang kerjakan baru-baru ini menggunakan Antd dan reac-redux, dan terdapat sebutan borang di dalamnya. Keperluan saya ialah melakukan pengesahan bahagian hadapan apabila pengguna memasukkan atribut getFieldDecorator；當(dāng)用戶提交表單之后，將后端返回的錯誤信息對應(yīng)到表單中，這里使用了Antd提供的自定義校驗，即FormItem的help和validateStatus yang disediakan oleh Antd digunakan di sini.

Tetapi saya mendapati bahawa apabila menggunakan pengesahan tersuai, getFieldDecorator就不在起作用了。那如果想使用getFieldDecoratorpengesahan dan ingin menggunakan pengesahan tersuai apabila bahagian belakang mengembalikan data, bagaimanakah saya harus menanganinya?

Terima kasih semua terlebih dahulu.
