1、CDN的方式引用相关js

<meta charset="UTF-8">
	<meta http-equiv="X-UA-Compatible" content="IE=edge">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">
	<title>授权结果</title>

	<script src="https://unpkg.com/axios/dist/axios.min.js"></script>

2、Result.html 获取参数的值

onMounted(() => {
					const queryString = new URLSearchParams(window.location.search);
					msg.value = queryString.get('msg');
});

注意：在传msg之前要encode下

例如：

@RequestMapping(path = "/myQrcode", method = RequestMethod.GET)
	public ModelAndView MyQrcode(@RequestParam(name = "msg", required = true) String msg, HttpServletRequest req,
			HttpServletResponse resp) {
		ModelAndView modelView = new ModelAndView();
		modelView.setViewName("Result");
		modelView.addObject("msg", msg);
		System.out.println(JSON.toJSONString(modelView));
		return modelView;
	}

try {
            String msg = "绑定成功";
			msg = URLEncoder.encode(msg,"utf-8");
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
		}

import java.net.URLEncoder;

3、encode的参数，页面收到以后会自动decode，也就是会输出绑定成功。

4、URLSearchParams事例：

const paramsString = "q=URLUtils.searchParams&topic=api";
const searchParams = new URLSearchParams(paramsString);

// 迭代查询参数
for (let p of searchParams) {
  console.log(p);
}

console.log(searchParams.has("topic")); // true
console.log(searchParams.has("topic", "fish")); // false
console.log(searchParams.get("topic") === "api"); // true
console.log(searchParams.getAll("topic")); // ["api"]
console.log(searchParams.get("foo") === null); // true
console.log(searchParams.append("topic", "webdev"));
console.log(searchParams.toString()); // "q=URLUtils.searchParams&topic=api&topic=webdev"
console.log(searchParams.set("topic", "More webdev"));
console.log(searchParams.toString()); // "q=URLUtils.searchParams&topic=More+webdev"
console.log(searchParams.delete("topic"));
console.log(searchParams.toString()); // "q=URLUtils.searchParams"
