我具有服务器配置,可以与Android客户端通话：
<?PHPrequire_once("MysqL.class.PHP");require_once("lib/autoloader.PHP");// Setting up the PubNub Server:use Pubnub\Pubnub;$pubnub = new Pubnub( "pub-c...", ## PUBliSH_KEY "sub-c..." ## SUBSCRIBE_KEY);// Publishing :$post_data = Json_encode(array("type"=> "groupMessage", "data" => array("chatUser" => "SERVER", "chatMsg" => "Now lets talk", "chatTime"=>1446514201516)));$info = $pubnub->publish('MainChat', $post_data);print_r($info);print_r($post_data);?>和HTML：
<!DOCTYPE HTML><HTML><head> <Title>PubNub PHP Test Page</Title></head> <body> <form method="POST" action="index.PHP"> <input type="submit" name="submit" value="TestSendMessage" /> </form> </body></HTML>由于我可以看到消息到达客户端AndroID应用程序的日志控制台,因此该发布功能在服务器中起作用,但是该消息从未正确解析,因此在没有SubscribeCallback的情况下,它不会出现在列表视图中：
public voID subscribeWithPresence(String channel) { this.channel = channel; Callback subscribeCallback = new Callback() { @OverrIDe public voID successCallback(String channel, Object message) { if (message instanceof JsONObject) { try { JsONObject JsonObj = (JsONObject) message; JsONObject Json = JsonObj.getJsONObject("data"); final String name = Json.getString(Constants.JsON_USER); final String msg = Json.getString(Constants.JsON_MSG); final long time = Json.getLong(Constants.JsON_TIME); if (name.equals(mpubNub.getUUID())) return; // Ignore own messages final ChatMessage chatMsg = new ChatMessage(name, msg, time); presentActivity.runOnUiThread(new Runnable() { @OverrIDe public voID run() { // Adding messages published to the channel mChatAdapter.addMessage(chatMsg); } }); } catch (JsONException e) { e.printstacktrace(); } } Log.d("PUBNUB", "Channel: " + channel + " Msg: " + message.toString()); } @OverrIDe public voID connectCallback(String channel, Object message) { Log.d("Subscribe", "Connected! " + message.toString()); //hereNow(false); // setStateLogin(); } }; try { mpubNub.subscribe(this.channel, subscribeCallback); //presenceSubscribe(); } catch (PubnubException e) { e.printstacktrace(); // Checking if success Log.d("Fail subscribe ", "on channel: " + channel); }}通过单击TestSendMessage在浏览器中测试服务器输出,将产生：
Array ( [0] => 1 [1] => Sent [2] => 14465159776373950 ) {"type":"groupMessage","data":{"chatUser":"SERVER","chatMsg":"Now lets talk","chatTime":1446514201516}}在应用程序中,从以下行输出日志：Log.d(“ PUBNUB”,“ Channel：” channel“ Msg：” message.toString());
返回值：D / PUBNUB：频道：MainChat消息：{“ type”：“ groupMessage”,“ data”：{“ chatUser”：“ SERVER”,“ chatMsg”：“ Now let talk”,“ chatTime”：1446514201516}}
确实应该这样,但是消息永远不会出现在消息的ListVIEw中,从而使JsON解析失败.
JsON标签在Constants类中很简单：
public static final String JsON_GROUP = "groupMessage";public static final String JsON_USER = "chatUser";public static final String JsON_MSG = "chatMsg";public static final String JsON_TIME = "chatTime";如何重新配置服务器发送,以成功进行应用内解析？
解决方法:
通过PubNub发送JsON
Send the JSON object without stringifying it first.对于PHP,不要对消息进行Json_encode. PubNub SDK将为您编码和解码.
这个：
$post_data = array("type"=> "groupMessage", "data" => array( "chatUser" => "SERVER", "chatMsg" => "Now lets talk", "chatTime"=>1446514201516));不是这个：
$post_data = Json_encode(array("type"=> "groupMessage", "data" => array( "chatUser" => "SERVER", "chatMsg" => "Now lets talk", "chatTime"=>1446514201516)));请解决此问题.
