mockjs简单使用

最近做了一个新的小项目，需要使用mockjs+axios来模拟后台数据，就来记录一下mockjs 的使用：

　　1. 安装mockjs和axios

　　　　npm install mockjs --save-dev

　　　　npm install axios --save

　　2.在项目里新建一个mock的文件夹，将mock的请求接口放在此文件夹里

　　

　　其中index.js里面的代码如下：

　　

// index.js
import Mock from "mockjs";
Mock.mobile_prefix = [
  "134",
  "135",
  "136",
  "137",
  "138",
  "139",
  "150",
  "151",
  "152",
  "157",
  "158",
  "159",
  "130",
  "131",
  "132",
  "155",
  "156",
  "133",
  "153"
];
Mock.bank_prefix = [
  "4367",
  "6227",
  "6228",
  "9559",
  "6222",
  "9558",
  "6216",
  "4563",
  "6013",
  "6221",
  "6210",
  "6014",
  "5218",
  "6282",
  "3568",
  "6226",
  "4218",
  "6229",
  "4864",
  "6029",
  "9988"
];
Mock.numeric = "0123456789";
let pagesize = 0;
const chartData = () => {
  // mock随机数据
  const Random = Mock.Random;
  let dataArr = [];
  for (let i = 1; i <= pagesize; i++) {
    let newData = {
      id: i,
      user_name: Random.cname(), // 随机生成中文姓名
      user_bank: Mock.getBank(), // 随机生成银行卡卡号（统一19位）
      phone: Mock.getMobile(), //手机号
      status: "已转账"
    };
    dataArr.push(newData);
  }
  return dataArr;
};
Mock.random = (len, list) => {
  if (len <= 1) {
    len = 1;
  }
  var s = "";
  var n = list.length;
  if (typeof list === "string") {
    while (len-- > 0) {
      s += list.charAt(Math.random() * n);
    }
  } else if (list instanceof Array) {
    while (len-- > 0) {
      s += list[Math.floor(Math.random() * n)];
    }
  }
  return s;
};

Mock.getMobile = () => {
  return Mock.random(1, Mock.mobile_prefix) + Mock.random(8, Mock.numeric);
};
Mock.getBank = () => {
  return Mock.random(1, Mock.bank_prefix) + Mock.random(15, Mock.numeric);
};
// Mock.mock(url,method,data) 三个参数对应 api地址、请求方式、请求参数
Mock.mock("/getData", "post", data => {
  pagesize = JSON.parse(data.body).pagesize;
  return {
    success: "true",
    code: "200",
    data: chartData()
  };
});

3. 将mock/index.js引入到项目里的main.js中

require("./mock/mock");

　　4. 在组件中调用接口获取模拟的数据

　　

 let params = { pagesize: this.pagesize };
      let count = this.total % this.pagesize;
      let page = parseInt(this.total / this.pagesize);
      if (this.current > page) {
        params.pagesize = count;
      }
      axios.post("/getData", params).then(res => {
        this.tableData = res.data.data;
      });
