我在订阅频道组时遇到错误。无法弄清楚原因。代码如下：

var pubnub = new PubNub({
        subscribeKey: subKey,
        publishKey: pubKey
      });

pubnub.addListener({
        status: function(s){
          console.log('status',s);
        },
        message: function(m) {
          var msg = m.message; // The Payload
          console.log('new message',msg);
        },
      });

pubnub.subscribe({
        channelGroups: [viewFinderChannelGroup],
        withPresence: false
      });

结果是： GET http://ps4.pubnub.com/v2/subscribe/…db1b&uuid=&pnsdk=PubNub-JS-Web%2F4.3.3 400（错误）

控制台输出没有多大帮助：

status Object {error: true, operation: "PNSubscribeOperation", statusCode: 400, errorData: Error: Error
at Request.<anonymous> (https://cdn.pubnub.com/sdk/javascript/pubnub.4.3.3.js:1330:…, category: "PNBadRequestCategory"}

【解决方案1】：

withPresence 不会为假。把wihPresence去掉就好了。试试下面的代码。

var pubnub = new PubNub({
        subscribeKey: subKey,
        publishKey: pubKey
      });

pubnub.addListener({
        status: function(s){
          console.log('status',s);
        },
        message: function(m) {
          var msg = m.message; // The Payload
          console.log('new message',msg);
        },
      });

pubnub.subscribe({
        channelGroups: [viewFinderChannelGroup]
      });
