Question

我有一个Struts操作，写入HttpServletResponse如下。代码仅适用于HTTP，但不适用于HTTPS。

BufferedInputStream in = null;
try {
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\";");
    // set response headers
    response.setContentLength(fileData.length);
    response.setContentType("application/octet-stream");

    //BUFFER
    int bufferSize = 2 * 1024 * 1024;
    in = new BufferedInputStream(new ByteArrayInputStream(fileData), bufferSize);
    byte[] buffer = new byte[bufferSize];
    int len = 0;

    // Loop through the input file and get the data chunks...
    while ((len = in.read(buffer, 0, bufferSize)) != -1) {
        response.getOutputStream().write(buffer, 0, len);
    }
} catch (Exception e) {
    throw new SystemException(e.getMessage());
} finally {
    response.getOutputStream().flush();
    response.getOutputStream().close();
}

服务器是Weblogic 10（重要吗？）。整个Web应用程序使用HTTPS，文件下载除外。它适用于Chrome和FF，但不适用于IE 8/9。以下消息显示在警告框中

Windows无法找到“https：// xxxxxxx”

Answer 1

这是一个已知的特定于IE的问题，另请参阅Microsoft支持网站：Internet Explorer is unable to open Office documents from an SSL Web site。要解决此问题，您需要在响应中明确设置以下标头：

response.setHeader("Cache-Control", "public");
response.setHeader("Pragma", "public");

IE显示“Windows无法找到https：// xxxxxxx”错误，可通过HTTPS下载
