我过去几天一直在讨论这个问题。我正在尝试将数据发布到安装了SSL证书的服务器上。
我一直在使用EasySSLSocketFactory和这里的EasyX509TrustManager类(http://code.google.com/p/transdroid/source/browse/trunk/src/org/xmlrpc/android/?r=103)以及以下代码:
StringEntity se = null;
try {
se = new StringEntity(tripArray.toString());
} catch (UnsupportedEncodingException e) { }
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(new Scheme("https", new EasySSLSocketFactory(), 443));
HttpParams params = new BasicHttpParams();
params.setParameter(ConnManagerPNames.MAX_TOTAL_CONNECTIONS, 30);
params.setParameter(ConnManagerPNames.MAX_CONNECTIONS_PER_ROUTE, new ConnPerRouteBean(30));
params.setParameter(HttpProtocolParams.USE_EXPECT_CONTINUE, false);
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
ClientConnectionManager cm = new SingleClientConnManager(params, schemeRegistry);
this.httpClient = new DefaultHttpClient(cm, params);
HttpPost httpPost = new HttpPost("https://xxx");
httpPost.setEntity(se);
httpPost.setHeader("Accept", "application/json");
httpPost.setHeader("Content-type", "application/json");
ResponseHandler responseHandler = new BasicResponseHandler();
try {
String response = this.httpClient.execute(httpPost, responseHandler).toString();
} catch (ClientProtocolException e) {
tripFail = true;
} catch (IOException e) {
tripFail = true;
}
但我似乎从我的请求中得到了以下回复:

有谁知道造成这种情况的原因是什么?我有点难过......
编辑:
我认为问题出在这里
Class.forName(String, boolean, ClassLoader) line: 234
Class.forName(String) line: 181
代码似乎是将一个空字符串传递给Class.forName()函数,导致它纾困..但我不确定是什么调用它以及为什么。
谢谢, 奥利

看起来Eclipse正在为我造成这个问题。正如gabe所说,Intellij idea社区版编译代码很好并且不会导致NullPointerException。我不知道是什么导致它,不知道如何解决它。我将从现在开始使用不同的IDE。
