HtmlUnit FailingHttpStatusCodeException：400錯誤的請求

Question

這是爲我的工作項目，所以我不能像我想要的那樣具體。

的Java應用程序我設計應該做到以下幾點：

• 填補了網頁的形式，
• 點擊了提交
• 打開顯示成功/失敗
了新的一頁
• 在5秒內，新頁面根據成功/失敗自動重定向到另一個頁面
• 數據庫因此被更新。

（網頁已經存在，是因爲我在這裏所描述的，和我的應用程序是假設自動處理它們設置）

我嘗試可以使用HtmlUnit來處理網頁，形式和點擊填充鈕釦。

但是我收到一些例外，我希望儘可能避免。

1）如果我在配置Web客戶端，像這樣：

wc = new WebClient(); 
    wc.setJavaScriptEnabled(false); 

的代碼做的事情是應該的，但引發此異常：

dec 09, 2015 5:28:37 PM com.gargoylesoftware.htmlunit.WebClient printContentIfNecessary 
INFO: statusCode=[400] contentType=[] 
dec 09, 2015 5:28:37 PM com.gargoylesoftware.htmlunit.WebClient printContentIfNecessary

    at workApps.Lazaruss1.App.main(App.java:80) 

代碼工作，數據庫已成功更新，但在最後一次重定向時失敗並且未打開最終頁面。 :(

2）當我配置的Web客戶端，例如：

wc.setThrowExceptionOnFailingStatusCode(false); 

我得到下面的異常和程序不能正常工作：這點後

dec 09, 2015 5:31:12 PM com.gargoylesoftware.htmlunit.WebClient printContentIfNecessary 
INFO: statusCode=[400] contentType=[] 
dec 09, 2015 5:31:12 PM com.gargoylesoftware.htmlunit.WebClient printContentIfNecessary

的代碼和退出數據庫不會更改。

我想要的是完全消除這些例外。我如何配置WebClient停止像這樣的混蛋？

這是初始頁的形式：

<form id="paymentPageData" action="processConfirmPaymentPage" method="post"> 

        <div style="display: none;"> 
         <input id="transactionId" name="tranId" type="hidden" value="1510351"/>

Answer 2

我解決了這個問題:)

刷新導致的頁面過於龐大，無法放入頁面對象。

我改變了重定向的URL：https://login.live.com/

而且現在的工作。
