Next.js中使用DELETE方法时，req.body未定义
我真的不知道为什么，但是当我尝试获取数据并将其放入响应正文中时，它显示未定义（在控制台中）。我有两个几乎相同的组件。一种使用 POST 方法并返回填充的正文，另一种使用 DELETE 方法并返回未定义的正文。我正在使用 Prisma 架构。
这是可以运行并返回 API 正文的 POST
export default function Product({
id_product,
name,
link_image,
price,
}: ProductProps) {
const [test, testing] = useState(false);
const { push: relocate } = useRouter();
const onAddToCart = async () => {
let response = await fetch("/api/addToCart", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({
id_product: id_product,
}),
});
if (response.ok) {
toast.success(`${name} was added to the cart`);
} else {
toast.error(`${name} is already in your cart`);
}
};
这是该函数的 API 的开始，const { id_product } = req.body 有效。
async function handlePost(req: NextApiRequest, res: NextApiResponse) {
const session = await getServerSession(req, res, authOptions);
const client = connexion()
const { id_product } = req.body;
const user = await client.user.findFirst({
where: { email: session?.user?.email || undefined}
})
let cart = await client.cart.findFirst({
where: {id_user: user?.id_user}
})
这就是我遇到的问题，除了方法之外，组件基本相同：
type ProductProps = products;
export default function ProductItem({
id_product,
description,
publication_date,
author,
name,
link_image,
price,
}: ProductProps) {
const onDeleteFromCart = async () => {
let data = {
id_product: id_product
}
let response = await fetch("/api/deleteFromCart", {
method: "DELETE",
headers: { "Content-Type": "application/json" },
body: JSON.stringify(data),
});
if (response.ok) {
toast.success(`${name} was succesfully removed from your cart`)
}
else {
toast.error(`Error`);
}
};
这是 API，const {id_product} = req.body 未定义
async function handleDelete(req: NextApiRequest, res: NextApiResponse) {
const session = await getServerSession(req, res, authOptions);
const client = connexion()
const { id_product } = req.body
console.log(id_product)
const user = await client.user.findFirst({
where: { email: session?.user?.email || undefined}
});
let cart = await client.cart.findFirst({
where: {id_user: user?.id_user}
});
let cart_item = await client.cart_item.findFirst({
where: {
id_cart: cart?.id,
id_product: id_product
}
})
我已经尝试解决这个问题几个小时了，但完全没有进展。
