加入聊天室。

  • targetId 聊天室会话 ID
  • messageCount 进入聊天室拉取消息数目，-1 时不拉取任何消息，0 时拉取 10 条消息，最多只能拉取 50
  • autoCreate 是否创建聊天室，TRUE 如果聊天室不存在，sdk 会创建聊天室并加入，如果已存在，则直接加入
  • callback 事件回调。SDK 从 5.3.1 版本开始支持 callback 方式回调。从 5.4.0 版本废弃该接口的其他回调方式，预计将在 6.x 版本删除此其他回调方式。如果传入了 callback 参数，仅触发 callback 回调。
  • 返回值 当次接口操作的状态码。0 代表调用成功 具体结果需要实现接口回调，非 0 代表当前接口调用操作失败，不会触发接口回调，详细错误参考错误码
  • 接口回调 onChatRoomJoined

Join a chatroom.

  • targetId The chatroom conversation ID
  • messageCount The number of messages to fetch upon entering the chatroom. -1 means no messages will be fetched, 0 means fetching 10 messages, with a maximum of 50 messages allowed.
  • autoCreate Whether to create the chatroom. If TRUE and the chatroom does not exist, the SDK will create the chatroom and join it. If the chatroom already exists, the SDK will directly join it.
  • callback Event callback. The SDK supports callback-based events starting from version 5.3.1. Other callback methods for this interface are deprecated as of version 5.4.0 and are expected to be removed in version 6.x. If the callback parameter is provided, only the callback will be triggered. call, and the specific result needs to be handled by the interface callback. Non-zero values indicate a failure in the current operation, and no interface callback will be triggered. Refer to the error codes for detailed error information.
