/**
 * 除保留参数外，一律移除
 * @param {string} url 地址
 * @param {string} removeKeyArr 待保留的参数名集合
 * @returns 重新拼接的地址
 * @example
 * // 地址是 hash 模式参数
 * keepUrlParams('http://www.test.com/#/detail?a=1&b=2&c=3', ['a', 'b']);
 * // => 'http://www.test.com/#/detail?a=1&b=2'
 * @example
 * // 地址 history 模式参数并存
 * keepUrlParams('http://www.test.com?a=1&b=2&c=3', ['a', 'b']);
 * // => 'http://www.test.com/?a=1&b=2'
 * @example
 * // 地址 history 模式参数并存 + 强制 history 模式返回
 * keepUrlParams('http://www.test.com?a=1&b=2&c=3', ['a', 'b'], true);
 * // => 'http://www.test.com/?a=1&b=2'
 * @example
 * // hash 模式和 history 模式参数并存
 * keepUrlParams('http://www.test.com?a=1&b=2&c=3#/detail?d=4', ['a', 'd']);
 * // => 'http://www.test.com/#/detail?a=1&d=4'
 * @example
 * // 地址是 hash 模式和 history 模式参数并存，且是多个参数
 * keepUrlParams('http://www.test.com?d=4&f=6#/detail?a=1&b=2&c=3', ['a', 'd']);
