SSM项目实战-前端-在Index.vue中展示第一页数据
1、util/request.js
import axios from "axios";let request = axios.create({baseURL: "http://localhost:8080",timeout: 50000 });export default request2、api/schedule.js
import request from "../util/request.js";export let getScheduleList = (queryvo) => {return request.get(`/schedule/${queryvo.pageNum}`,{params:{uid:queryvo.uid}}) }; export let updateSchedule=data=>{return request.put("/schedule",data) } export let saveSchedule=data=>{return request.post("/schedule",data) } export let delSchedule=id=>{return request.delete(`/schedule/${id}`) }3、Index.vue

7、模板字符串 ``
在ES6（ECMAScript 2015）中，模板字符串是一种新的字符串类型，它使用 反引号（`） 来定义，可以包含嵌入式表达式（即${expression}）。模板字符串的出现为JavaScript提供了更灵活和强大的字符串处理能力。
模板字符串的主要作用包括：
格式化字符串：通过使用嵌入式表达式，可以将变量或表达式的值直接嵌入到字符串中。这使得字符串的格式化更为方便和直观。例如：
let name = "John"; let greeting = `Hello, ${name}!`; // 输出 "Hello, John!"
多行字符串：模板字符串可以包含多行内容，这对于处理多行文本或代码非常有用。例如：
let multiLineString = `This is a multi-line string.`; // 输出一个跨越多行的字符串
字符串插值：通过使用嵌入式表达式
${expression}，可以在字符串中插入变量或表达式的值。这使得字符串的动态生成更为简单。例如：let name = "John"; let message = `My name is ${name}.`; // 输出 "My name is John."
转义字符：模板字符串中，反斜杠（\）用于转义字符，可以用来表示特殊字符（如换行符、制表符等）。例如：
let escapedString = `\n represents a new line.`; // 输出 "\ represents a new line."在实际开发项目中，模板字符串可以帮助你更方便地处理字符串，提高代码的可读性和可维护性。特别是在处理复杂的字符串逻辑时，模板字符串可以使得代码更加清晰和易于理解。
