java.net.UnknownHostException：無法解析主機“@MYIPADDRESS，當使用android + mongodb時

Question

我創建了一個像這樣的MongoClientURI：

MongoClientURI uri = new MongoClientURI( "mongodb://User_name:Password@MyIPAddress:27017/"+TEST_SKETCH_APP );

        MongoClient instance = MongoDatabaseConnection.getInstance(uri);
        DB db = instance.getDB(uri.getDatabase());
        DBCollection collection = db.getCollection(SKETCH_COLLECTION);

        BasicDBObject  dbObject = new BasicDBObject();

        dbObject.put("name", url[0]);
        dbObject.put("password", url[1]);
        dbObject.put("email", url[2]);
        dbObject.put("phoneNumber", url[3]);

        collection.insert(dbObject);

我從AsyncTask調用這個方法：

@Override
    protected JSONObject doInBackground(String... urls) {

        // params comes from the execute() call: params[0] is the url.
        try {
            return saveValues(urls);
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return  null;
    }

我也擁有互聯網連接所需的所有權限：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

但是我仍然無法向在該IP地址中運行的數據庫插入值。 完整錯誤說：

Timed out after 10000 ms while waiting for a server that matches AnyServerSelector{}.
Client view of cluster state is {type=Unknown, servers=[{address=@MYIPADDRESS:27017,
 type=Unknown, state=Connecting, exception={com.mongodb.MongoException$Network: 
 Exception opening the socket}, caused by {java.net.UnknownHostException: 
 Unable to resolve host "@MYIPADDRESS": No address associated with hostname}, 
 caused by {android.system.GaiException: android_getaddrinfo failed: 
 EAI_NODATA (No address associated with hostname)}}]

我知道IP ADDRESS是正確的，因為我可以在chrome http://MYIPADDRESS:27017/

得到這個回報：

It looks like you are trying to access MongoDB over HTTP on the native driver port.

FWIW我得到了同樣的錯誤。 我試圖靜態連接，但你需要在構造函數中進行連接。
