react下载文件有哪两种方式

static async download(params) {

   let form = document.createElement('form');

   form.style.display = 'none';

   form.action = `${api}tCmPaymentOrd/export`;

   form.method = 'POST';

   document.body.appendChild(form);

   // 动态创建input并给value赋值

   for (var key in params) {

     var input = document.createElement('input');

     input.type = 'hidden';

     input.name = key;

     input.value = params[key];

     form.appendChild(input);
