方法一

import qs from 'qs';

export function createRequestForm(data) {
  //创建form表单
  var temp_form = document.createElement("form");
  temp_form.action = data.url;
  //如需打开新窗口，form的target属性要设置为'_blank'
  temp_form.target = data.target || "_self";
  temp_form.method = data.method || "post";
  temp_form.style.display = "none";
  //添加参数
  var location = data.url.split('?')
  var theParams =qs.parse(location[1],{ignoreQueryPrefix:true});
  var PARAMTERS={...theParams,...data.params};
  for (var item in PARAMTERS) {

    opt.value = PARAMTERS[item];
    temp_form.appendChild(opt);
  }
  document.body.appendChild(temp_form);
  //提交数据
  temp_form.submit();
}
