htmlunit 登錄問題-htmlunit模擬登錄 驗證碼錯誤

htmlunit模擬登錄 驗證碼錯誤

使用htmlunit模擬登錄的時候 ，首先穿創建了一個webclient 用webclient請求登錄頁面，同事請求解析驗證碼，驗證碼解析正確，然後開始登錄系統，一直提示驗證碼錯誤。
WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_11);
webClient.getOptions().setJavaScriptEnabled(true);

webClient.getOptions().setCssEnabled(false);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.getOptions().setThrowExceptionOnScriptError(false);

webClient .getOptions().setUseInsecureSSL(true);
WebWindow webWindow = webClient.getCurrentWindow();

    WebRequest request1 = new WebRequest(new URL("http://rd2.zhaopin.com/s/loginmgr/login.asp"));
    HtmlPage htmlPage = webClient.getPage(webWindow,request1);
    String name =  htmlPage.getWebClient().getWebWindows().get(0).getName();
    System.out.println(name);
    //第三步 獲取界面元素
    HtmlInput userName = htmlPage.getHtmlElementById("LoginName");
    HtmlInput password = htmlPage.getHtmlElementById("Password");
    HtmlInput checkCode = htmlPage.getHtmlElementById("CheckCode");
    HtmlInput btn = htmlPage.getHtmlElementById("login");


    WebRequest request = new WebRequest(new URL("https://passport.zhaopin.com/checkcode/imgrd"));

    UnexpectedPage imagePage = webClient.getPage(webWindow,request);
    InputStream in =  imagePage.getWebResponse().getContentAsStream();
    File storeFile = new File("D:/zlzp.png");  
    BufferedOutputStream output = new BufferedOutputStream(new FileOutputStream(storeFile));
    byte[] buf = new byte[2048];  
    int length = in.read(buf);  
    while (length != -1) {  
        output.write(buf, 0, length);  
        length = in.read(buf);  
    }  
    in.close();  
    output.close();  
    String valCode = new OCR().recognizeText(new File("D:\\zlzp.png"), "png");
    System.out.println(valCode);
    userName.setAttribute("value", "");
    password.setAttribute("value", "");
    checkCode.setAttribute("value", valCode);
    HtmlPage page2 = btn.click();
    System.out.println("\n\n\n");
    System.out.println(page2.asText());

最佳回答：

用fiddler看下，是不是你請求了多次頁面，也就是你識別的驗證碼不是最終的，或者你沒有帶上cookie
