一、a 標簽

移動端不支持

onDownFile= (url, filename) => {
    const downUrl = `http://10.1.109.123:19092/down/to?url=${encodeURIComponent(url)}`;
    // 創建隱藏的可下載鏈接
    const eleLink = document.createElement('a');
    eleLink.download = filename;
    eleLink.style.display = 'none';
    // 字符內容轉變成blob地址
    const blob = new window.Blob([downUrl]);
    eleLink.href = URL.createObjectURL(blob);
    // 觸發點擊
    document.body.appendChild(eleLink);
    eleLink.click();
    // 然后移除
    document.body.removeChild(eleLink);
  }
