post请求导出表单。

postExcelFile(params, url) { //params是post请求需要的参数，url是请求url地址
  var form = document.createElement("form");  //创建form表单节点
  form.style.display = 'none';         
  form.action = url;
  form.method = "post";
  form.enctype = "application/x-www-form-urlencoded;charset=UTF-8";
  document.body.appendChild(form);

  for(var key in params){
    var input = document.createElement("input");
    input.type = "hidden";
    input.name = key;
    input.value = params[key];
    form.appendChild(input);
  }
  form.submit();
  form.remove();   //删除form表单节点
},

onclick(){
     let obj = {};
     let url = 'www.baidu.com'
     this.postExcelFile(obj,url)   // 导出成功。

}
