📚 2.封装一个fetch请求

💻 代码实现

;(async () => {
    class HttpRequestUtil {
        async get(url) {
            const res = await fetch(url)
            const data = await res.json()
            return data
        }
        async post(url, data) {
            const res = await fetch(url, {
                method: "POST",
                headers: {
                    "Content-Type": "application/json",
                },
                body: JSON.stringify(data),
            })
            const result = await res.json()
            return result
        }
        async put(url, data) {
            const res = await fetch(url, {
                method: "PUT",
                headers: {
                    "Content-Type": "application/json",
                },
                data: JSON.stringify(data),
            })
            const result = await res.json()
            return result
        }
        async delete(url, data) {
            const res = await fetch(url, {
                method: "DELETE",
                headers: {
                    "Content-Type": "application/json",
                },
                data: JSON.stringify(data),
            })
            const result = await res.json()
            return result
        }
    }
    const httpRequestUtil = new HttpRequestUtil()
    const res = await httpRequestUtil.get("http://golderbrother.cn/")
    console.log(res)
})()
