[英]Patch data fetched from API
我是一個初學者,正在嘗試創建一個練習項目。 我正在嘗試“修補”從 API 獲取的數據。 我的 json 文件如下所示:
{
"classes": [
{
"title": "Office Syndrome",
"length": "60 Minutes",
"instructor": "A. W.",
"difficulty": "Intermediate",
"description": "Suitable for people who are always constantly inactive working in front of computers.",
"availableSpot": "10",
"id": 1
},
{
"title": "Digestive Flow",
"length": "60 Minutes",
"instructor": "MJ",
"difficulty": "Beginners",
"description": "Good for digestion",
"availableSpot": "8",
"id": 2
}
]
我正在嘗試創建一個功能,其中 class 可預訂,每次預訂后 availableSpot 將減少 1。
我的 handleBook function 目前看起來像這樣:
const handleBook = (index) => {
setSelectedYogaClass(true);
if (selectedYogaClass === index) {
fetch("http://localhost:8000/classes", {
method: "PATCH",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ availableSpot: data.availableSpot - 1 }),
})
.then((res) => {
if (!res.ok) {
throw Error("Sorry, something went wrong");
}
})
.then((res) => {
console.log(res);
})
.catch((err) => {
setBookingError(err);
});
}
console.log(selectedYogaClass);
setModalIsOpen(false);
};
這就是我如何稱呼 function
<button
key={index}
onClick={() => handleBook(index)}
className="button button--outline"
>
Yes
</button>
但是,我收到 404 錯誤,想知道問題出在哪里? 誰能指出我做錯了什么?
非常感謝您!
