上述两种召唤人工的方式均可实现，采用相同的调用方式，可以参考MainContent.vue的transform方法。
```
//召唤人工
transform() {
    let transformData = {
        channel: 'WEB',
        controlType: "TRANS2AGENT",
        mediaType: "TEXT",
        content: 'hello',
        sourceType: "CUSTOMER",
        to: this.$Chat.getChannelId(),
        "from": this.$Chat.userId,
        senderNickname: this.$Chat.userName
    };
    let that = this;
    let transSuccess = function (data) {
        if (data['resultCode'] === '0') {
            that.sendUserInfo();
        } else {
            EventBus.$emit("toAgentFailed");
        }
    }
    this.$Chat.send(transformData, transSuccess);
},
```
Demo当前在send方法调用失败时，会发送toAgentFailed事件，该事件会触发用户留言的方法。成功时，会向客服座席发送用户在接入时填写的用户信息，可以参考[用户接入](https://support.huaweicloud.com/devg-webdemo-cec/cec_05_1116.html)中的信息；具体方法如下：
```
//向座席发送用户信息
sendUserInfo() {
    let storage = window.localStorage;
    let userInfo = storage.getItem("sc_chat_user");
    if (userInfo) {
        let data = JSON.parse(userInfo);
        let message = '';
        if (data.userPhone) {
            message += ('用户电话:' + data.userPhone + ",");
        }
        if (data.userEmail) {
            message += ('用户邮箱:' + data.userEmail);
        }
        if (message !== '') {
            let connectMessage = {
                channel: 'WEB',
                controlType: "CHAT",
                mediaType: "TEXT",
                content: message,
                sourceType: "CUSTOMER",
                to: this.$Chat.getChannelId(),
                "from": this.$Chat.userId,
                senderNickname: this.$Chat.userName
            };
            this.$Chat.send(connectMessage);
        }
    }
}
```
