调用 openStream() 会引发 java.net.ConnectException 异常:连接超时:连接

Question

public String  pdfReadData() throws Exception
{
String pdfText = null;
try
{
    driver.get("https://www.....pdf");
    driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
    URL url= new URL(driver.getCurrentUrl());
    BufferedInputStream fileToParse = new BufferedInputStream(url.openStream());
    System.out.println("step1");
    PDFParser parser= new PDFParser(fileToParse);
    parser.parse();
    COSDocument cosDocument  = parser.getDocument();
    PDDocument pdDocument = new PDDocument(cosDocument);
    if(pdDocument.isEncrypted()) 
    {
        StandardDecryptionMaterial sdm  = new StandardDecryptionMaterial(PDF_OWNER_PASSWORD);
        pdDocument.openProtection(sdm); // org.apache.pdfbox.exceptions.CryptographyException: Error: The supplied password does not match either the owner or user password in the document.
        //pdDocument.decrypt(objConfigurationFile.PDF_OWNER_PASSWORD)// the same like above
    }
    pdfText= new PDFTextStripper().getText(pdDocument);
    System.out.println("pdf Value" + pdfText);
    // parser.getPDDocument.close();
    //parser.
    // driver.manage.timeouts.implicitlyWait(100, TimeUnit.SECONDS);
}
catch (MalformedURLException e2)
{
    System.err.println("URL string could not be parsed "+e2.getMessage());
} 
catch (Exception e) 
{
    e.printStackTrace();
}
return pdfText;
}

}

在 eclipse 中运行此代码会启动带有 pdf 文档的 URL，然后给出以下异常。同一组代码在同一台机器的scala中运行。不知道为什么会这样。

Answer 1

System.setProperty("https.proxyHost","127.0.0.1" );
System.setProperty("https.proxyPort","3128" );

在上面的代码之前添加这行代码解决了问题。
