uni对h5环境下的链接query解析跳转有误

[xiaobeilo]

问题描述
h5页面在history模式下, 通过vue-cli-plugin-uni/packages/h5-vue-router处理后的链接会解析错误

复现步骤
[复现问题的步骤]

1. 设置manifest.json下的h5.router为history
2. npm run dev:h5
3. 打开链接 http://localhost:8080/?key=:value
   4.观察链接

[或者可以直接贴源代码]

预期结果
链接不应该发生跳转, 跳转也应该是一个正确合法的链接地址

实际结果
打开页面之后会发现链接 被修改成了http://localhost:8080/[object%20Object]

补充信息
已调试代码, 猜测原因如下:

// node_modules/@dcloudio/vue-cli-plugin-uni/packages/h5-vue-router/dist/vue-router.esm.js
//2280行:
HTML5History.prototype.ensureURL = function ensureURL (push ) {
    if (getLocation(this.base) !== this.current.fullPath) {
// getLocation得到的是一个decode的url, 而this.current.fullPath并没有经过decode, 因此带 ":"的链接在该条件下会不相等, 继而让代码执行发生了后续错误的跳转行为
      var current = cleanPath(this.base + this.current.fullPath);
      // fixed by xxxxxx
      var location = {
        path: current,
        params: {
          __id__: this.current.params.__id__
        }
      };
      push ? pushState(location, location.params.__id__) : replaceState(location, location.params.__id__);
    }
  }; 
// 2306行:
function getLocation (base) {
  var path = decodeURI(window.location.pathname);
  if (base && path.indexOf(base) === 0) {
    path = path.slice(base.length);
  }
  return (path || '/') + window.location.search + window.location.hash
}
