如何在 Pubnub 中重新连接？

我正在使用 PubNub 在我的 Js 代码中传输通知。一旦互联网断开并恢复，我无法弄清楚如何在 PubNub 中重新连接。

恢复：在我的初始化和执行中为真

this.listeners = {
  message: msgEvent => {
    console.log(msgEvent);
  },
  status: statusEvent => {
    if (statusEvent.category === "PNNetworkUpCategory") {
      this.pubnub.reconnect();
}}};

对我不起作用。

完整代码：

this.pubnub = new PubNub({
  subscribeKey: this.serverDetails.authInfo.subscribeKey,
  authKey: this.serverDetails.authInfo.authKey,
  uuid,
  restore: true
  ssl: true
});

this.listeners = {
  message: msgEvent => {
    console.log(msgEvent);
  },
  status: statusEvent => {
    if (statusEvent.category === "PNNetworkUpCategory") {
      this.pubnub.reconnect();
    }
  }
};

this.pubnub.addListener(this.listeners); 

软件开发工具包：4.27.2

期望：尝试重新连接 PubNub max N 次），订阅现有订阅频道。

看看它，您可能会得到一些您没有检查的其他状态响应...而且我认为您需要autoNetworkDetection使用状态来宣布网络何时关闭或开启的标志PNNetworkDownCategory and PNNetworkUpCategory. i.e.

this.pubnub = new PubNub({
  subscribeKey: this.serverDetails.authInfo.subscribeKey,
  authKey: this.serverDetails.authInfo.authKey,
  uuid,
  restore: true,
  ssl: true,
  autoNetworkDetection: true
});

this.listeners = {
  message: msgEvent => {
    console.log(msgEvent);
  },
  status: statusEvent => {
    if (statusEvent.category === "PNNetworkUpCategory") {
      this.pubnub.reconnect();
    } else {
      // check for other status events - PNTimeoutCategory, PNNetworkIssuesCategory, etc
      console.log(statusEvent.category);
    } 
  }
};

如果失败并且您仍然遇到重新连接问题，您应该设置标志listenToBrowserNetworkEvent to false因为这允许 SDK 重新连接逻辑接管。 IE。

this.pubnub = new PubNub({
  subscribeKey: this.serverDetails.authInfo.subscribeKey,
  authKey: this.serverDetails.authInfo.authKey,
  uuid,
  restore: true,
  ssl: true,
  listenToBrowserNetworkEvents: false
});
