Question

我创建了一个像这样的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);

我从AsyncTask调用此方法：

@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;
    }

我也拥有互联网连接所需的所有权限：

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

但是我仍然无法向在该IP地址中运行的数据库插入值。完整的错误说：

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是正确的，因为我可以在chrome http://MYIPADDRESS:27017/

中输入它

得到了这个回报：

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

Answer 1

FWIW我得到了同样的错误。我试图静态连接，但你需要在构造函数中进行连接。

java.net.UnknownHostException：无法解析主机“@MYIPADDRESS，当使用android + mongodb时
