您的user状态是一个字符串，并作为字符串更新。但您正在将其作为对象user.fullname进行访问。
其次，您提交的redux操作带有一个空的用户对象，而不是表单值：
addUser({
fullname: "",
email: "",
password: ""
});
将表单更改为对每个值使用不同的useState，或者将当前user状态更改为对象。然后改为发送该对象：
const [user, setUser] = useState({
fullname: "",
email: "",
password: ""
});
const onChange = e => {
setUser({...user, [e.target.name]: e.target.value});
};
addUser(user);
最后，您并没有在reducer中使用有效负载，只是返回状态。通过如下返回来保存用户：
case "ADD_USER":
return action.payload;
<Input
type="email"
name="email"
value={user.email}
id="email"
placeholder="myemail@email.com"
onChange={onChange}
/>
我应该把什么放在这里的价值
