无法保存XFDF表单的POST数据内容 [英] Not able to Save the POST data contents of an XFDF form

问题描述

我们不能能够从XFDF表单保存POST数据内容.使用PDF内的按钮触发POST事件.

We are Not able to Save the POST data contents from an XFDF form. The POST event is triggered using a button inside the PDF.

我们在服务器端使用了 Java + SPRING .

We are using Java + SPRING on server side.

例外:

java.io.IOException: Expected > for tag: <{1}/> near line 1, column 13

在itext演示页面中也观察到相同的错误！在这里是: http://itextpdf.com:8180/book/xfdf

推荐答案

问题是您正在使用XFDF阅读器发布FDF数据. FDF和XFDF是不同的格式，XFDF阅读器将其视为XML字符串，并引发有关未关闭标签的错误.

The problem is you're posting FDF data but using the XFDF reader. FDF and XFDF are different formats, and the XFDF reader is treating it as an XML string and throwing an error about unclosed tags.

如果您仅提供FDF文件，则需要以下内容:

If you're just providing FDF files, you'd want something like:

FdfReader fdfReaderObject = new FdfReader(request.getInputStream());
