java使PDF文件上的问号可读

5 月，2 周 Questions & Answers 286

我已经解析了一个带有URL的网页，它基本上是一个强制下载页面上PDF的页面。使用Jsoup中的ignorecontenttype（）方法，我成功地显示了一大堆文本，但它包含黑色椭圆的问号，如下所示：这是我的密码：

org.jsoup.nodes.Document document1 = null;
Connection.Response downloadPopUp = Jsoup.connect("https://www.capitaliq.com/ciqdotnet/login.aspx?redirect=%2fCIQDotNet%2fFilings%2fDocumentRedirector.axd%3fversionId%3d" + ID + "%26type%3dpdf%26forcedownload%3dtrue/login.php").userAgent("Chrome/44.0.2403.125")
     .method(Connection.Method.GET)
     .timeout(1000000)
     .ignoreContentType(true)
     .execute();
document1 = Jsoup.connect("https://www.capitaliq.com/ciqdotnet/login.aspx?redirect=%2fCIQDotNet%2fFilings%2fDocumentRedirector.axd%3fversionId%3d" + ID + "%26type%3dpdf%26forcedownload%3dtrue").userAgent("Chrome/44.0.2403.125")
     .data("cookieexists", "false")
     .data("myLogin$myUsername", "MyEmail")
     .data("myLogin$myPassword", "MyPassword")
     .data("myLogin$myLoginButton.x", "22")
     .data("myLogin$myLoginButton.y", "8")
     .data("__VIEWSTATE", viewState)
     .data("__EVENTVALIDATION", eventValidation)
     .data("myLogin$myEnableAutoLogin", "on")
     .timeout(1000000)
     .cookies(downloadPopUp.cookies())
