在我的例子中，输入输入字段输出到浏览器的url作为查询字符串，使用React JS功能组件如下所示

import React, { useEffect, useState } from 'react'
import { useHistory } from 'react-router-dom'

const Search = () => {
  const [query, setQuery] = useState('')
  const history = useHistory()

  const onChange = (e) => {
    setQuery(e.target.value)
  }

  useEffect(() => {
    const params = new URLSearchParams()
    if (query) {
      params.append('name', query)
    } else {
      params.delete('name')
    }
    history.push({ search: params.toString() })
  }, [query, history])

  return <input type="text" value={query} onChange={onChange} />
}

export default Search

浏览器URL查询

/搜索吗?name = query_here

我更喜欢你使用下面的ES6风格的函数:

getQueryStringParams = query => {
    return query
        ? (/^[?#]/.test(query) ? query.slice(1) : query)
            .split('&')
            .reduce((params, param) => {
                    let [key, value] = param.split('=');
                    params[key] = value ? decodeURIComponent(value.replace(/\+/g, ' ')) : '';
                    return params;
                }, {}
            )
        : {}
};

对于react-router v4.3

const addQuery = (key, value) => {
  let pathname = props.location.pathname;
  // returns path: '/app/books'
  let searchParams = new URLSearchParams(props.location.search);
  // returns the existing query string: '?type=fiction&author=fahid'
  searchParams.set(key, value);
  this.props.history.push({
    pathname: pathname,
    search: searchParams.toString()
  });
};

const removeQuery = (key) => {
  let pathname = props.location.pathname;
  // returns path: '/app/books'
  let searchParams = new URLSearchParams(props.location.search);
  // returns the existing query string: '?type=fiction&author=fahid'
  searchParams.delete(key);
  this.props.history.push({
    pathname: pathname,
    search: searchParams.toString()
  });
};

function SomeComponent({ location }) {
  return <div>
    <button onClick={ () => addQuery('book', 'react')}>search react books</button>
    <button onClick={ () => removeQuery('book')}>remove search</button>
  </div>;
}

要了解更多关于URLSearchParams:

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

//Iterate the search parameters.
for (let p of searchParams) {
  console.log(p);
}

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

使用React Router V6，我们可以像这样实现它

import { useNavigate, createSearchParams } from 'react-router-dom';

/* In React Component */
const navigate = useNavigate();
const params = {
  color: 'blue',
};
const options = {
  pathname: '/shop/Clothes/dresses',
  search: `?${createSearchParams(params)}`,
};
navigate(options, { replace: true });

对于React Router v6+，只需使用新的useSearchParams钩子(特别是setSearchParams):

const [searchParams, setSearchParams] = useSearchParams()

setSearchParams(`?${new URLSearchParams({ paramName: 'whatever' })}`)

对于React Router v5使用useHistory:

const history = useHistory()

history.push({
    pathname: '/the-path',
    search: `?${new URLSearchParams({ paramName: 'whatever' })}`
})

URLSearchParams只是一个可选的方便助手。

也可以这样写

this.props.history.push(`${window.location.pathname}&page=${pageNumber}`)
