php - Chrome 正在导出错误的 "file extension"而不是 xls

Question

我是 phpexcel 的新手，所以我使用附加的代码将数据从数据库导出到 xls 文件。它在除 Chrome 之外的任何其他浏览器中都可以正常工作，其中下载的文件没有“扩展名”，而是 xls。我的代码有问题还是应该修改浏览器设置？有人能帮我吗？谢谢

文件已下载 [Inventário Livros (20-05-2015)-]

我的代码:

您在响应中添加了一个 http header “Content-Disposition”。此 header 告诉 Chrome 浏览器和其他浏览器 ;-)，浏览器应在其文件保存窗口中显示哪个文件名。只需将 .xls 添加到您的文件名中，浏览器就会使用它。
