javascript - 如何从 docxtemplater.js 输出 docx 以在 jszip 中输入

问题描述

使用来自jszip和docxtemplater的示例，我正在尝试将多个 docx-Documents 添加到 zip 存档中，但我失败了。我的存档仅包含 0 字节不可读的 docx 文件。

我想我不明白如何将二进制模式的 docx 文件添加到存档中。我添加了从上面提到的示例中融合而来的相当长的示例代码。

您能告诉我如何修改 generate() 函数的输出或将文件添加到 zip 存档吗？

解决方案

在研究了 muellermarkus 的评论后，我正在咨询项目负责人，并在 github 上打开了一个 issue。那里有一个答案，我在这里复制作为参考。主要障碍是在将 docx 文件添加到存档时添加 {base64: true} 作为选项。
