javascript Url 传参的坑，base64参数和url参数之间的转移

在url传参时会对特殊字符进行转义，所以通过base64传参是需要进行处理

简单说下base64的使用

1，在项目根目录下安装

npm install --save js-base64
2，在项目文件中引入

let Base64 = require(‘js-base64‘).Base64

import { Base64 } from "js-base64";

3，在项目文件中使用

Base64.encode(‘大元‘) // fdsfds5f34
Base64.decode(‘fdsfds5f34‘) // 大元

简单坑的点

我的解决办法

 urlSwitchBase64(wantData) {
      if (wantData.includes("%2B")) {
        wantData = wantData.replace(/\+/g, "%2B");
      }
      if (wantData.includes("%20")) {
        wantData = wantData.replace(/\ /g, "%20");
      }
      if (wantData.includes("%2F")) {
        wantData = wantData.replace(/\//g, "%2F");
      }
      if (wantData.includes("%25")) {
        wantData = wantData.replace(/\%/g, "%25");
      }
      if (wantData.includes("%26")) {
        wantData = wantData.replace(/\?/g, "%26");
      }
      if (wantData.includes("&3D")) {
        wantData = wantData.replace(/\=/g, "&3D");
      }
      if (wantData.includes("%23")) {
        wantData = wantData.replace(/\#/g, "%23");
      }
      return wantData;
    }
