vue发送请求数据类型转换为FromData

Vue使用axios，设置axios请求格式为FormData##

//设置axios为form-data
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
axios.defaults.headers.get['Content-Type'] = 'application/x-www-form-urlencoded';
axios.defaults.transformRequest = [function (data) {
    let ret = ''
    for (let it in data) {
      ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&'
    }
    return ret
}]
