提交成功或失败后如何在反应表单中显示 toastr 警报？

Question

我想知道如何在点击“发送信息”按钮显示“您的信息已发送”时显示toastr警报，如果失败“您的信息无法发送，这里有问题！”

我要发送的代码是：

 const sendMail = async (data: FormData) => {
    const response = await fetch('https://us-central1-my-website.cloudfunctions.net/apply-function', {
      method: 'POST',
      body: data,
    });
  };

Answer 1

一旦解决或拒绝，response 对象将有一个名为 status 的属性，它指示请求是被服务器解决还是拒绝 (API) .您可以使用 status 属性相应地显示警报。

示例

import React from 'react';

const Mail = () => {
    const [alert, setAlert] = React.useState({ show: false, message: '' });

    const sendMail = async (data: FormData) => {
        //  It's better to use try catch block when writing an async function.
        try {
            const response = await fetch(
                'https://us-central1-my-website.cloudfunctions.net/apply-function',
                {
                    method: 'POST',
                    body: data,
                }
            );

            if (response.status === 200) {
                setAlert({
                    show: true,
                    message: 'Your information has been sent!',
                });
            }
        } catch {
            // If response was not successful.
            setAlert({
                show: true,
                message: 'Your information could not be sent!',
            });
        }
    };

    return (
        <>
            {/* Other components.. */}
            <Toaster show={alert.show} message={alert.message} />
        </>
    );
};
