uniApp：使用vue3+Vite4+pinia+sass技术栈构建（02）-封装api请求

import { useStore } from "@/store/user"  //引入pinia 获取用户登录后的token

//通过env文件，区分开发环境和正式环境
if (import.meta.env.MODE === "development") {
    BASE_URL = import.meta.env.VITE_DEV_URL
} else {
    BASE_URL = import.meta.env.VITE_PRO_URL
}

const isUrl = (url: string) => {
    let rx = /^http?/i
    if (rx.test(url)) {
        return true
    } else {
        return false
    }
}

//定义请求类型
enum methodtType {
    GET = "GET",
    OPTIONS = "OPTIONS",
    HEAD = "HEAD",
    POST = "POST",
    PUT = "PUT",
    GDELETEET = "DELETE",
    TRACE = "TRACE",
    CONNECT = "CONNECT",
}
//请求类
class urlRequest {
    header = {
        PCTOKEN: useStore().userInfo.token  //登录token，key根据实际情况修改
    }
    setHeader(header: any) {  //提供修改header的方法，不过不需要可以删除
        this.header = header
    }
    request(
        url: string,
        method: methodtType,
        params: Array<String> = [],
        showError: boolean = true  //可以不要，留在这里的意思是出错信息要不要再基类中处理，例如需要登录的接口没有登录，提示用户登录
    ) {
        let request_url = url
        if (!isUrl(url)) {  // 判断一下传过来的地址是带有域名还是不带有域名，提高代码的扩展性。
            request_url = BASE_URL + url
        }
