android - 使用 REST 接口(interface) : Cannot connect 连接到数据库

Question

我正在尝试通过正在开发的 Android 应用程序中的 mongolabs REST 接口(interface)连接到 mongodb，但它没有连接，而是抛出异常(或者至少我认为是)。我对后端不熟悉，所以如果我犯了一个致命的菜鸟错误，请原谅我。这是日志

01-10 16:28:50.377: W/System.err(630): javax.net.ssl.SSLException: hostname in certificate didn't match: != OR OR >01-10 16:28:50.377: W/System.err(630): at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:185) 01-10 >16:28:50.388: W/System.err(630): at org.apache.http.conn.ssl.BrowserCompatHostnameVerifier.verify(BrowserCompatHostnameVerifier.java:54)

下面是我编写的用于访问数据库并获取名称等项目的 MongoLabHelper 类的一部分

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");               
}

这里是它使用的类的一部分

   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 线程有您需要的信息:

Secure HTTP Post in Android

为了方便起见，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);
}
