通过 wicket 下载 zip 文件 [英] Download a zip file through wicket

问题描述

我正在使用 wicket 框架，并且我已经通过 Java 代码制作了一个 zip 文件，我想要一个链接来下载它，我不知道是否可能或者我应该通过 wicket 制作 zip 文件(但是不是 Java)，然后有一个下载链接.

I am using wicket framework, and I have made a zip file by Java code, I want to have a link to download it, I don't know if it is possible or I should make the zip file by wicket (but not Java) and then have a link to download.

推荐答案

看一看 ZipResourceStream.使用此类，您可以动态生成目录的 zip 内容，并使用 org.apache.wicket.markup.html.link.ResourceLink 和 ResourceStreamResource 链接到它.

Take a look at ZipResourceStream. With this class you can generate zip contents of a directory on the fly, and use a org.apache.wicket.markup.html.link.ResourceLink with ResourceStreamResource to link to it.

File file = new File(path);
IResourceStream resStream = new ZipResourceStream(file);
ResourceStreamResource resource = new ResourceStreamResource(resStream);
ResourceLink link = new ResourceLink("link", resource);
add(link);

或者，如果您更喜欢使用其他工具压缩文件，您可以使用 DownloadLink:

Alternatively, if you prefer to zip the file with another tool, you can use DownloadLink:

File zipFile = generateZipFile();
IModel fileModel = new Model(zipFile);
add(new DownloadLink("dllink", fileModel);

如果您更喜欢在链接的 onClick 中即时生成文件，请查看以下问题:如何使用 Wicket 的下载链接使用动态生成的文件?

If you prefer to generate the File on the fly in the Link's onClick, take a look at this question: How to use Wicket's DownloadLink with a file generated on the fly?
