我正在尝试通过我正在开发的android应用程序中的mongolabs REST接口连接mongodb，但它没有连接，而是它抛出异常（或者至少我认为它是）。我不熟悉后端，所以如果我犯了一个致命的菜鸟的错误，请原谅我。这是logcat
01-10 16：28：50.377：W / System.err（630）：javax.net.ssl.SSLException：证书中的主机名不匹配：！= OR OR＆gt; 01-10 16:28： 50.377：W / System.err（630）：at org.apache.http.conn.ssl.AbstractVerifier.verify（AbstractVerifier.java:185)01-10＆gt; 16：28：50.388：W / System.err（630） ）：at org.apache.http.conn.ssl.BrowserCompatHostnameVerifier.verify（BrowserCompatHostnameVerifier.java:54）
下面是我编写的MongoLabHelper类的一部分，用于访问数据库并获取名称等项目
HttpClient client;
JSONObject db;
MongoLabHelper() throws ClientProtocolException, IOException, JSONException{
client = new DefaultHttpClient();
HttpGet request = new HttpGet("https://api.mongolab.com/api/1/databases/breadcrumbs/collections/crumbs?apiKey=xxxxxxxxxxxxx");
HttpResponse response = client.execute(request);
HttpEntity entity = response.getEntity();
InputStream in = entity.getContent();
String json = in.toString();
db = new JSONObject(json);
}
public String getName(String name) throws JSONException {
JSONObject doc = db.getJSONObject(name);
return doc.getString("name");
}
，这是
中使用的类的一部分 public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String name = "Crumb Not Available";
MongoLabHelper help;
try {
help = new MongoLabHelper();
name = help.getName("Chipotle");
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
setContentView(R.layout.breadcrumb);
TextView crumbName = (TextView) findViewById(R.id.crumb_name);
crumbName.setText(name);

您实际上需要显式设置HttpClient来处理SSL。我相信这个stackoverflow线程有你需要的信息：
为方便起见，我将从线程中复制相关的代码：
private HttpClient createHttpClient()
{
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.DEFAULT_CONTENT_CHARSET);
HttpProtocolParams.setUseExpectContinue(params, true);
SchemeRegistry schReg = new SchemeRegistry();
schReg.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schReg.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));
ClientConnectionManager conMgr = new ThreadSafeClientConnManager(params, schReg);
return new DefaultHttpClient(conMgr, params);
}

作为帮助者;
我还实现了Android库来抽象MongoLab通信
主要目标是直接从Android应用程序中轻松使用可在云中利用Mongo强大功能的库！
注意：我还包括使用MongoLab的自定义ACRA记者。
这是第一个版本（我将继续扩展）：
