react地址栏获取查询值 query-parameters

https://reacttraining.com/react-router/web/example/query-parameters

React Router does not have any opinions about how your parse URL query strings. Some applications use simple key=value query strings, but others embed arrays and objects in the query string. So it's up to you to parse the search string yourself.
In modern browsers that support the URL API, you can instantiate a URLSearchParams object from location.search and use that.
In browsers that do not support the URL API (read: IE) you can use a 3rd party library such asquery-string.
