无法使用Selenium Webdriver./PDFBox读取pdf内容获取java.io.IOException：错误：文件结束异常消息

编程问答 2022-08-16

问题描述

我正在处理网页，在该网页上单击链接可在同一窗口中打开pdf文件。我必须阅读该pdf文件的内容以验证一些数据。我不想下载pdf来阅读内容。我需要从浏览器本身读取内容。从URL如何验证打开的文件是pdf文件。使用最新的Chrome浏览器版本。有人可以帮我吗？

此处URL的扩展名不以.pdf结尾。 样本pdf网址：blob：https://xxxxxxxxxx.com/15946946-ca67-40eb-abd5-3fd8d477519d

示例代码：

String currentRawURL = driver.getcurrenturl();
        String[] currentURL = currentRawURL.split("blob:");
        String PDFURL = currentURL[1];
        URL url = new URL(PDFURL);
        InputStream is = url.openStream();
        BufferedInputStream fileParse = new BufferedInputStream(is);
        PDDocument document = PDDocument.load(fileParse);
        PDFTextStripper pdf = new PDFTextStripper();
        String pdfContent = pdf.getText(document);
        document.close();
        System.out.println(" PDF Content  : " +pdfContent);
        // TestNG assertion for checking if text is present in content
        Assert.assertTrue(pdfContent.contains("test"));

控制台输出：
