如何在 selenium 中阅读 PDF 内容

Question

我正在尝试验证 PDF 中的内容，我正在使用 href 获取 URL 并将其传递到下面的代码中。 URL 使用 HTTPS，所以我面临以下问题。任何人都可以帮助我如何继续并帮助我阅读 pdf 数据。提前致谢

重试网址是https://XXXXXXXXXXXXXXXXX/apex/DA_ViewArchive?docType=pdf&docid=2229123

        URL PDFUrl = new URL(url);
        BufferedInputStream TestFile = new BufferedInputStream(PDFUrl.openStream());
        PDFParser TestPDF = new PDFParser((RandomAccessRead) TestFile);
        TestPDF.parse();
        String TestText = new PDFTextStripper().getText(TestPDF.getPDDocument());
        System.out.println("Document Text is   "+   TestText);

错误是

Answer 1

您是否在所需的驱动程序功能中设置了接受 SSL 证书？

DesiredCapabilities dc = DesiredCapabilities.chrome ()       
dc.setCapability (CapabilityType.ACCEPT_SSL_CERTS, true)
WebDriver driver = new ChromeDriver (dc);

首先下载包含所有依赖项的 pdfbox JAR 2.0.13 并将其导入。 现在从 URL 读取 PDF 文件。

public String readPDFInURL(String text) throws EmptyFileException, IOException {
        System.out.println("Enters into READ PDF");
        String output = "";
        URL url = new URL(driver.getCurrentUrl());
        System.out.println("url :  " + url);
        InputStream is = url.openStream();
        BufferedInputStream fileToParse = new BufferedInputStream(is);
        PDDocument document = null;
        try {
            document = PDDocument.load(fileToParse);
            output = new PDFTextStripper().getText(document);
            if (output.contains(text)) {
                System.out.println("Element is matched in PDF is : " + text);
                test.log(LogStatus.INFO, "Element is displayed in PDF " + text);
            } else {
                System.out.println("Element is not  matched in PDF");
                test.log(LogStatus.ERROR, "Element is not displayed in PDF :: " + text);
                throw new AssertionError("Element is not displayed" + text);
            }
        } finally {
            if (document != null) {
                document.close();
            }
            fileToParse.close();
            is.close();
        }
        return output;
    }

您可以使用 Maven 添加 pdfbox jar 依赖项，并开始阅读使用 Selenium 下载的 pdf 或现有的 pdf 文档。

例如：

  File file = new File("C:/PdfBox_Examples/new.pdf");
  PDDocument document = PDDocument.load(file);

  //Instantiate PDFTextStripper class
  PDFTextStripper pdfStripper = new PDFTextStripper();

  //Retrieving text from PDF document
  String text = pdfStripper.getText(document);
  System.out.println(text);

  //Closing the document
  document.close();
