初始化SDK #

构造SDK配置 #

    SyOptions syOptions = SyOptions();
    syOptions.appId = "您的AppID";
    syOptions.secret = "您的secret";
    //SDK运行环境
    syOptions.environment=SyEnvironmentEnum.prod;

调用初始化方法： #

    SyClient.getInstance().init(syOptions: syOptions);

用户登录 #

通过业务方UUID登录 #

    SyClient.getInstance().loginByUUID(
        uuid: "uuid", // 第三方 uuid, 测试使用, 正式请使用 token 方式登录
        callback: SyCallBack(
            onSuccess: (authInfo) {
                //todo 处理登录成功逻辑
            }, 
            onFail: (code, msg) {
                //todo 处理登录失败逻辑
            })
    );

通过token登录 #

    SyClient.getInstance().loginByToken(
        token: "token",
        callback: SyCallBack(
            onSuccess: (authInfo) {
                //todo 处理登录成功逻辑
            }, 
            onFail: (code, msg) {
                //todo 处理登录失败逻辑
            })
    );   

会话管理 #

创建会话（无用户信息） #

    SyClient.getInstance().conversationManager().createSignConversationByUid(userId: userId, callback: SyCallBack<SyConversation>(
        onSuccess: (conversation) {
          /*会回调会话的信息*/
          /*sessionId 是会话id,发送消息需要*/
          var sessionId =  conversation.sessionId;
          /*会话中对方存在sdk服务器的用户信息*/
          var info = conversation.contact;
        },
        onFail: (code, msg) {
          /*错误*/
        })
    );

创建会话（有用户信息） #

    SyContact contact =SyContact();
    //contact.userId 为必传字段，其他信息可以根据业务需要自行增加
    contact.userId="";
    contact.avatar="";
    contact.nickName="";
    SyClient.getInstance().conversationManager().createSignConversationByContact(contact: contact, callback: SyCallBack<SyConversation>(
        onSuccess: (conversation) {
          // conversation 回调会话的信息
          // conversation.sessionId 是会话id,发送消息需要*/
        },
        onFail: (code, msg) {
            //处理错误信息
        })
    );

获取会话列表 #

     SyClient.getInstance().conversationManager().getConversationList(
        callback: SyCallBack<List<SyConversation>>(onSuccess: (conversationList) {
          /*会话列表*/
        }, 
        onFail: (code, msg) {
          /*异常*/
        })
    );

    syMessage.sessionId = "会话ID";
    int pageSize = 20;
    SyClient.getInstance().chatManager().getMessageList(
        starMessage: syMessage,
        pageSize: pageSize,
        callBack: SyCallBack(
            onSuccess: (messageList) {
                //todo 处理消息
                }, 
            onFail: (code, error) {
                //todo 处理查询失败
            })
    );

发送消息 #

     _getReceiveUserInfo() {
        SyContact receiveUserInfo = SyContact();
        receiveUserInfo.userId = "消息接收人用户ID";
        receiveUserInfo.avatar = "接收人头像";
        receiveUserInfo.nickName = "消息接收人用户昵称";
        return receiveUserInfo;
    }

    //发送文本消息
    _sendTxtMessage(String content) {
        SyMessage syMessage = SyMessage.buildTxtMsg(_getReceiveUserInfo(), "会话ID");
        syMessage.content=content;
        SyClient.getInstance().chatManager().sendMessage(
            syMessage: syMessage,
            callBack: SyCallBack(onSuccess: (syMessage) {
            //todo 发送成功回调
            }, 
                onFail: (code, error) {
            //todo 发送失败回调
            })
        );
    }
    
    //发送图片消息（传入图片URI地址）
    _sendImgMessage(Uri uri) {
        SyMessage syMessage = SyMessage.buildImgMsg(_getReceiveUserInfo(), sessionId);
        syMessage.uri=uri;
        SyClient.getInstance().chatManager().sendMessage(
            syMessage: syMessage,
            callBack: SyCallBack(onSuccess: (syMessage) {
                //todo 发送成功回调
            }, 
            onFail: (code, error) {
                //todo 发送失败回调
            })
        );
    }
    
    //发送自定义消息
    _sendCustomMessage(String content) {
            SyMessage syMessage = SyMessage.buildCustomMsg(_getReceiveUserInfo(), sessionId);
            syMessage.content=content;
            SyClient.getInstance().chatManager().sendMessage(
                syMessage: syMessage,
                callBack: SyCallBack(onSuccess: (syMessage) {
                //todo 发送成功回调
                }, 
                onFail: (code, error) {
                //todo 发送失败回调
                })
        );
    }

保存消息到本地 #

    SyMessage syMessage = SyMessage.buildTxtMsg(_getReceiveUserInfo(), content);

    SyClient.getInstance().chatManager().saveMessageToLocal(
        syMessage: syMessage,
        callBack: SyCallBack(
            onSuccess: (syMessage) {
            //todo 保存成功回调
            }, 
            onFail: (code, error) {
            //todo 保存失败回调
            },
        ),
    );    

删除消息 #

    SyClient.getInstance().chatManager().deleteMessage(
      msgId: "消息ID",
      sessionId: '会话ID',
      callBack: SyCallBack(
        onSuccess: (bool status) {
          //todo 处理删除成功逻辑
        },
        onFail: (String code, String error) {
          //todo 处理删除失败逻辑
        },
      ),
    );

消息监听 #

    1、初始化消息监听

    OnMessageListener onMessageListener=OnMessageListener(
        onMessage: (List<SyMessage> syMessage) {
            //todo 处理新消息
        },
        onStatusChange: (List<SyMessage> syMessage) {
            //todo 处理状态变更消息
        },
    )
    2、注册消息监听
    
    SyClient.getInstance().chatManager().addMessageListener(onMessageListener);

    3、移除消息监听

    SyClient.getInstance().chatManager().removeMessageListener(onMessageListener);
