在Chrome浏览器中，我们经常需要下载并安装一些扩展程序或插件。然而，有时候会遇到下载的安装包校验与验证失败的情况。为了解决这个问题，我们可以按照以下步骤进行操作：
1. 首先，确保你的Chrome浏览器已经更新到最新版本。如果还没有更新，请前往Chrome官方网站（https://www.google.com/chrome/）下载并安装最新版本的Chrome浏览器。
2. 打开Chrome浏览器，点击右上角的“更多工具”按钮，然后选择“开发者工具”。这将打开一个名为“开发者工具”的窗口。
3. 在“开发者工具”窗口中，点击左侧的“网络”选项卡。这将显示当前网页的所有网络请求和响应。
4. 在“网络”选项卡中，找到你正在尝试下载的安装包所在的URL。通常，这个URL会以`http://localhost:8080/path/to/your/package.zip`的形式出现。例如，如果你正在尝试下载的安装包路径为`/path/to/your/package.zip`，那么URL应该是`http://localhost:8080/path/to/your/package.zip`。
5. 接下来，点击“网络”选项卡下方的“控制台”按钮。这将打开一个新的控制台窗口，用于查看和编辑JavaScript代码。
6. 在控制台窗口中，输入以下代码：
javascript
var url = new URL(window.location.href);
var filePath = url.pathname + '.zip';
var fileName = url.pathname.substring(url.pathname.lastIndexOf('/') + 1);
var fileSize = fileName.split('.').pop();

var fileType = fileExtension.substring(fileExtension.length - 3);
