verbinden Android Client zu sails.js

Question

Ich benutze nkzawa socket.io android client. Wie kann ich es mit dem Server sails.js verbinden? habe ich versucht, die Ansätze von Sending Socket request from Client (iOS & Android) to Sails.js Server und Simple Sails.js and Android Example aber ich erhalte die folgenden Fehler auf meinem Segel-Server:

This will start this socket off with an empty session, i.e. (req.session === {}) 
That "anonymous" section will only last until the socket is disconnected unless you persist the session id in your database, 
or by setting the set-cookie response header for an HTTP request that you *know* came from the same user (etc) 
Alternatively, just make sure the socket sends a `cookie` header or query param when it initially connects.

Das ist mein Android-Client:

JSONArray arr = new JSONArray(); 
JSONObject obj = new JSONObject(); 
try { 
    obj.put("url", "/user/new"); 
} catch (JSONException e) { 
    e.printStackTrace(); 
} 
arr.put(obj); 
socket.emit("get", arr); 

Answer 1

Im Objekt, das Sie zu emittieren haben gebaut Der Server, der den JSONArray-Wrapper überspringt, sollte das Problem beheben. Ändern Sie den Code wie folgt:

Wenn das Problem weiterhin besteht, gibt es einen anderen Bereich, der untersucht werden kann.

Socket-io wird das Problem der Analyse virtueller Anfrage stellen, wenn die Client-ID niedriger als 0.11.0 ist. Eine Lösung hierfür ist die Bearbeitung der Datei parse-sdk-metadata.js, die je nach Ihrer NPM-Version in /node_modules/sails-hook-sockets/lib/oder/node_modules/sails/node_modules/sails-hook-sockets/lib/ gefunden werden kann.

Darin ändern folgendes:

if (!(handshake.headers[SDK_META_PARAMS.version] || handshake.query[SDK_META_PARAMS.version])) { 
      handshake.query[SDK_META_PARAMS.version] = '0.9.0'; 
} 

TO:

if (!(handshake.headers[SDK_META_PARAMS.version] || handshake.query[SDK_META_PARAMS.version])) { 
      handshake.query[SDK_META_PARAMS.version] = '0.11.0'; 
} 

Dies sollte die Error (SAILS:HOOK:SOCKETS:PARSE_VIRTUAL_REQ) lösen, die Sie erhalten!
