DefaultHttpClient，證書，https和發佈問題！

Question

我的應用程序需要能夠發佈到https並保留使用cookie創建的會話。到目前爲止，我有幾種不同的方式來解決這個問題，而且沒有任何工作。目前我正在研究使用DefaultHttpClient，因爲它應該自動保留使用Cookie創建的會話。這爲我節省了閱讀cookie並與其他每個帖子一起提交的痛苦。但是，當我嘗試使用我擁有的代碼進行發佈時，發佈失敗，並顯示下面列出的證書錯誤。

我以前用另一種方式嘗試解決問題並使用HttpsURLConnection工作時發現了此證書錯誤，但這不會自動保留會話。

有人可以看看我的代碼，告訴我我做錯了什麼，我可以做得更好，需要改變什麼才能讓它工作。謝謝！！

我一直試圖解決這個問題幾天，現在我知道在哪裏。每當我進一步得到進一步推進。有人可以幫助我！ =）

//my posting function 
    private static String post(String urlString, List<NameValuePair> nameValuePairs) 
    throws MalformedURLException, ProtocolException, IOException { 
     DataOutputStream ostream = null; 

     HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER; 

     DefaultHttpClient client = new DefaultHttpClient(); 

     SchemeRegistry registry = new SchemeRegistry(); 
     SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory(); 
     socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier); 
     registry.register(new Scheme("https", socketFactory, 443)); 
     SingleClientConnManager mgr = new SingleClientConnManager(client.getParams(), registry); 
     DefaultHttpClient http = new DefaultHttpClient(mgr, client.getParams()); 

     HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier); 

     HttpPost httppost = new HttpPost(urlString); 

     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

     HttpResponse response = http.execute(httppost); 

     return response.toString(); 
}

Answer 1

這個問題是由於客戶端應用程序是無法驗證建立從信任錨（根受信任的證書頒發機構）和SSL服務器證書路徑證書。因此，此證書不受信任，SSL握手失敗。

apache HTTPClient API提供了一個很好的功能，可以幫助你。 SSLSocketFactory構造函數can take a KeyStore parameter包含可信證書。

然後，您可以：

1. 創建一個KeyStore含有兩種根CA證書或直接在服務器證書keytool。
2. 這個密鑰庫添加到應用程序
3. 構建的SSLSocketFactory這個KeyStore
