url参数转对象，对象转url参数

将带参数的url地址中的参数提取组合成对象

const getUrlParams = (search) => {

    const queryString = (search && search.split('?')[1]) || location.search.split('?')[1] || ''

    const queryList = queryString.split('&')

    let result = {}

    queryString && queryList.map((item) => {

        let keyValue = item.split('=')

        result[keyValue[0]] = decodeURIComponent(keyValue[1])

    })

    return result

}

将参数拼成对象，作为参数传入，返回值是拼接后的url参数，不带问号  ' ? '

const getParamStrFromObj = (data = {}, paramProxy = '') => Object.keys(data)

    .map(key => {

        if (paramProxy) {

            return `${paramProxy}[${key}]=${encodeURIComponent(data[key])}`

        }

        return `${key}=${encodeURIComponent(data[key])}`

    })

    .join('&')
