解决微信中无法下载文件问题
2025-11-25 16:36:17 by wst
web开发当我们看到一个（下载链接）二维码，扫描的时候发现微信中无法下载文件，此时就要提示用户到浏览器中打开。
作为开发者，这个在操作层面怎么实现呢？
实现步骤
1.在自己的页面中添加一个div，内容如下：
<!-- 微信下载提示 -->
<div id="wechatTip" class="mt-4 p-4 bg-yellow-50 border border-yellow-200 rounded-lg text-yellow-800 text-sm leading-relaxed hidden">
<div class="flex items-start space-x-2">
<svg class="w-5 h-5 mt-0.5 flex-shrink-0" fill="currentColor" viewBox="0 0 24 24">
<path d="M12 2C6.48 2 2 6.48 2 12s4.48 10 10 10 10-4.48 10-10S17.52 2 12 2zm1 15h-2v-2h2v2zm0-4h-2V7h2v6z"/>
</svg>
<div>
微信提示：如点击“立即下载”无法拉起浏览器，可点击页面右上角
<span class="font-semibold">“···”</span> →
<span class="font-semibold">“在浏览器打开”</span>，即可正常下载。
</div>
</div>
</div>
2. 在script中添加检测脚本，内容如下：
const isWechat = /MicroMessenger/i.test(navigator.userAgent);
if (isWechat) document.getElementById('wechatTip').classList.remove('hidden');
3. 然后在微信中查看就可以看到这个提示了。截图如下：
