如果我在JasperReports服务器Web GUI中导航到我以前上传的InHiltsResource（内容资源）*.xlsx Excel文档，它在Firefox和Chrome中运行良好，提供保存或打开文件，但在Internet Explorer中失败，通过在选项卡中显示文件二进制内容：-（

我做了很多研究，但没有找到确切的原因，尽管有些观点可能会指出原因：

（更一般的观察：）

  • IEs/Jasper GUI发送的HTTP请求头（
    ACCEPT
    string）似乎错误/不完整/IE不兼容
    • （因此，Jasper Servlets HTTP响应头（
      Content-Type
      string）似乎是错误的/不完整的/IE不兼容的
（当深入思考这一点时：）

  • JasperServer本身（或者在交付时一定程度上作为容器的Tomcat）不应该尝试确定要交付的内容类型吗？
    • 可以让用户手动设置，也可以通过试探法（文件扩展名、内容解析等）来确定。
      • 这样，它也可以与文件一起存储（我只会在用户希望覆盖启发式确定类型的结果时才这样做）
    • 由于文件名或URL已经很容易表明它是一个*.xlsx文件，并且内容以
      PK…
      开头，因此它已经强烈表明它确实是一个（压缩）Excel文件
    • 因此，我将看到两种基本的方法，这通常会起作用。。。
      • 请求头（Jasper交付的GUI页面）应明确定义内容类型（可能仅当响应功能本身无法轻松确定时）
      • （通常可能更合适：）响应头（Jasper/Tomcat服务器逻辑）应该明确地设置请求的、正确的或估计的内容类型
        • 查看IE或FF的头响应，可以清楚地看到此处未设置任何
          内容类型
          ，尽管REST-API调用将其设置为
          应用程序/八位字节流；charset=UTF-8
以下是我已经检查过的详细信息：

  • ok：FF和IE的HTTP响应头对我来说没有显著差异（尽管请求头非常不同）（见下文），因此表明结果内容检测的魔力存在一些问题（在这种情况下FF和Chrome似乎更好）

  • IE和FF的HTTP头请求/响应周期：

    • IE9（通过车载开发工具捕获）：

    • 我花了相当长的时间在这个问题上，但谷歌都没有（我想知道为什么没有其他人会有这个问题，尽管这在我看来很常见）各种调试也没有帮助。也许我必须详细地使用相关的Jasper类来进一步调试，但也许其他人也有这个问题，或者知道解决方案？

    似乎有一种手动解决方法：

    我们实现了一个servlet过滤器类，以尝试在我们知道MIME类型设置错误的情况下设置响应的内容配置头
