1.机器人智能回复接口：http://www.liulongbin.top:3006/api/robot
2.机器人语音接口：http://www.liulongbin.top:3006/api/synthesize
目标效果：
1.点击发送按钮，即可发送自己在聊天框输入的内容【空格/没输入，则不会被发送】
2.聊天机器人会回复自己发送的内容
3.机器人可以将它发送的聊天信息的语音自动播放【该接口有时行，有时不行。好的时候可以智能回应1中的内容，并读出该内容的语音】
4.在有多次对话之后，右边的滚动条会默认处于右边最下方，以显示最新的对话
5.按回车键，也可发送自己在聊天框输入的内容
更换的新接口：
1.机器人智能回复接口：http://www.liulongbin.top:3006/api/robot
2.机器人语音接口：http://www.liulongbin.top:3006/api/synthesize
e.g.1初始状态：
e.g.2用户输入牛奶：
机器人智能回复，并且读出回复内容的语音
b站黑马Ajax案例代码——聊天机器人效果.mp4
e.g.3多次对话后，右边滚动条还是在右边的最下面
重点原理：
1.jQuery中trim方法
2.jquery中append方法
3.jQuery中attr方法-设置/返回被选元素的属性值
4.通过设置 <audio> 自动播放语音
5.keyup是某个键盘按键松开触发
6.keyup是某个键盘按键松开触发
代码部分：
1.chat.js（全是重点）
$(function () {
// 初始化右侧滚动条
// 这个方法定义在scroll.js中
resetui();//resetui函数用于实现：每次发送内容之后，页面会自动滚动到最底部
//1.给发送按钮绑定点击事件
$('#btnSend').on('click',function () {
var text = $('#ipt').val().trim();//trim()用于去除两端的空格
//(1)如果用户输入的是空格/没输入
if (text.length <= 0) {
return $('#ipt').val('');//清空#ipt文本框内容
}
//(2)如果用户输入了内容，则将该内容追加至页面上显示
//字符串不允许回车换行，所以下一行中append后面的内容得在一行上
$('#talk_list').append('<li class="right_word"><img src="img/person02.png" /><span>' + text + '</span></li>');
$('#ipt').val('');//发送完毕后，清空#ipt文本框内容
//发送完毕，实现页面自动滚动到最底部
resetui();
//调用下面的getMsg函数，传递参数text给下面的text
getMsg(text);
})
//2.获取聊天机器人发送回来的消息
function getMsg(text1) {//此处text1,接收上面的text参数
$.ajax({
method: 'GET',url: 'http://www.liulongbin.top:3006/api/robot',data: {
spoken: text1
},success: function (res) {
if (res.message === 'success') {
//接收机器人发送过来的聊天消息
var msg = res.data.info.text;
$('#talk_list').append('<li class="left_word"><img src="img/person01.png"/><span>' + msg + '</span></li>');
//发送完毕，实现页面自动滚动到最底部
resetui();
//调用下面的getVoice函数，传递参数msg给下面的text2
getVoice(msg);
}
}
})
}
//3.将机器人发送的聊天信息转换为语音
function getVoice(msg1) {//此处msg1和,接收上面的msg参数
$.ajax({
method: 'GET',url: 'http://www.liulongbin.top:3006/api/synthesize',data: {
text: msg1
},success: function (res) {
// console.log(res);
if (res.status === 200) {
//播放语音
$('#voice').attr('src',res.voiceUrl);//给audio设置了新的src属性
}
}
})
}
//4.按回车键可以发送自己聊天消息内容
$('#ipt').on('keyup',function (e) {
//e.key返回按键的字符串形式（ie9以上支持）
//用户弹起键盘的回车键的时候
if (e.key === 'Enter') {
//触发发送的按钮
$('#ntnSend').click();
}
})
