Question

我正在尝试从某个包含pdf文件的网址中提取文本但我收到的错误是这样的 - 信息：文档已加密 2015年5月27日上午9:27:50 org.apache.pdfbox.filter.FlateFilter decode

public void getTextFromPdf(String urlS) throws IOException {
        driver.get(urlS);
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
        URL url = new URL(driver.getCurrentUrl());
        BufferedInputStream fileToParse = new BufferedInputStream(url.openStream());

        //parse()  --  This will parse the stream and populate the COSDocument object. 
        //COSDocument object --  This is the in-memory representation of the PDF document
        PDFParser parser = new PDFParser(fileToParse);
        parser.parse();

        //getPDDocument() -- This will get the PD document that was parsed. When you are done with this document you must call    close() on it to release resources
        //PDFTextStripper() -- This class will take a pdf document and strip out all of the text and ignore the formatting and           such.
        System.out.println(urlS);
        String output = new PDFTextStripper().getText(parser.getPDDocument());
        System.out.println(output);
        parser.getPDDocument().close();
        driver.manage().timeouts().implicitlyWait(100, TimeUnit.SECONDS);

Answer 1

请将此代码用于PDFBox工作：

        PDDocument doc = PDDocument.loadNonSeq(fileToParse, null);
        String output = new PDFTextStripper().getText(doc);
        doc.close();

关于依赖项，read this或使用您可以找到的here的pdfbox-app jar文件。
