目录
1.服务端提供所有直播间的列表信息
1.marshmallow.py
from marshmallow_sqlalchemy import SQLAlchemyAutoSchema,auto_field
from .models import LiveStream,db
from application.apps.users.models import User
from marshmallow import post_dump
class StreamInfoSchema(SQLAlchemyAutoSchema):
id = auto_field()
name = auto_field()
room_name = auto_field()
user = auto_field() class Meta:
model = LiveStream
include_fk = True
include_relationships = True
fields = ["id","name","room_name","user"]
sql_session = db.session @post_dump()
def user_format(self, data, **kwargs):
user = User.query.get(data["user"])
if user is None:
return data data["user"] = {
"id":user.id,
"nickname": user.nickname if user.nickname else "",
"ip": user.ip_address if user.ip_address else "",
"avatar": user.avatar if user.avatar else ""
}
return data
marshmallow.py
2.views.py
from .marshmallow import StreamInfoSchema
from flask import current_app
@jsonrpc.method("Live.stream.list")
@jwt_required # 验证jwt
def list_stream():
# 验证登陆用户信息
current_user_id = get_jwt_identity() # get_jwt_identity 用于获取载荷中的数据
user = User.query.get(current_user_id)
if user is None:
return {
"errno": status.CODE_NO_USER,
"errmsg": message.user_not_exists,
"data": { }
} # 查询数据库中所有的直播流
stream_list = LiveStream.query.filter(LiveStream.status==True, LiveStream.is_deleted==False).all()
sis = StreamInfoSchema()
data_list = sis.dump(stream_list,many=True) # 使用requests发送get请求,读取当前srs中所有的直播流和客户端列表
import requests,re,json
stream_response = requests.get(current_app.config["SRS_HTTP_API"]+"streams/")
client_response = requests.get(current_app.config["SRS_HTTP_API"]+"clients/")
stream_text = re.sub(r'[^\{\}\/\,0-9a-zA-Z\"\'\:\[\]\._]', "", stream_response.text)
client_text = re.sub(r'[^\{\}\/\,0-9a-zA-Z\"\:\[\]\._]', "", client_response.text)
stream_dict = json.loads(stream_text)
client_dict = json.loads(client_text) # 在循环中匹配所有的客户端对应的总人数和当前推流用户的IP地址
for data in data_list:
data["status"] = False
for stream in stream_dict["streams"]:
if data["name"] == stream["name"]:
data["status"] = stream["publish"]["active"]
break
data["clients_number"] = 0
for client in client_dict["clients"]:
if data["name"] == client["url"].split("/")[-1]:
data["clients_number"]+=1
if client["publish"] and "/live/"+data["name"]==client["url"]:
data["user"]["ip"] = client["ip"]
return {
"errno": status.CODE_OK,
"errmsg": message.ok,
"stream_list": data_list
}
views.py
2.前端显示房间列表
1.房间列表页面初始化:live_list.html
把上面的客户端live_list.html,修改成live.html,并新建live_list.html,代码:
<!DOCTYPE html>
<html>
<head>
<title>好友列表</title>
<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">
<meta charset="utf-8">
<link rel="stylesheet" href="../static/css/main.css">
<script src="../static/js/vue.js"></script>
<script src="../static/js/axios.js"></script>
<script src="../static/js/main.js"></script>
<script src="../static/js/uuid.js"></script>
<script src="../static/js/settings.js"></script>
</head>
<body>
<div class="app setting" id="app">
<div class="bg">
<img src="../static/images/rooms_bg.png">
</div>
<img class="back" @click="goto_home" src="../static/images/user_back.png" alt="">
<div class="add_friend_btn" @click="add_room">
<img src="../static/images/add_room.png" alt="">
</div>
<div class="friends_list room_list">
<div class="item" v-for="room in rooms">
<div class="avatar">
<img class="user_avatar" :src="room.avatar" alt="">
</div>
<div class="info">
<p class="username">{{room.name}}</p>
<p class="fruit">人数：{{room.num}}</p>
</div>
<div class="behavior pick">直播</div>
<div class="goto"><img src="../static/images/arrow1.png" alt=""></div>
</div>
</div>
</div>
<script>
apiready = function(){
init();
new Vue({
el:"#app",
data(){
return {
rooms:[{"avatar":"../static/images/avatar.png",name:"房间名称",num:5}],
prev:{name:"",url:"",params:{}},
current:{name:"live",url:"live_list.html",params:{}},
}
},
created(){ },
methods:{
add_room(){ },
goto_home(){
// 退出当前页面
this.game.outFrame("live","live_list.html", this.current);
},
}
});
}
</script>
</body>
</html>
房间列表页面初始化:live_list.html
2.房间列表页面CSS样式
.room_list{
position: absolute;
top: 18rem;
}
3.前端获取后端传过来的直播流列表:get_room_list
获取服务端的直播流列表, live_list代码:
<!DOCTYPE html>
<html>
<head>
<title>房间列表</title>
<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">
<meta charset="utf-8">
<link rel="stylesheet" href="../static/css/main.css">
<script src="../static/js/vue.js"></script>
<script src="../static/js/axios.js"></script>
<script src="../static/js/main.js"></script>
<script src="../static/js/uuid.js"></script>
<script src="../static/js/settings.js"></script>
</head>
<body>
<div class="app user setting" id="app">
<div class="bg">
<img src="../static/images/rooms_bg.png">
</div>
<img class="back" @click="goto_home" src="../static/images/user_back.png" alt="">
<div class="add_friend_btn" @click="add_room">
<img src="../static/images/add_room.png" alt="">
</div>
<div class="friends_list room_list">
<div class="item" v-for="room in rooms">
<div class="avatar">
<img class="user_avatar" :src="room.user && settings.static_url+room.user.avatar" alt="">
</div>
<div class="info">
<p class="username">{{room.room_name}}</p>
<p class="fruit">人数：{{room.clients_number}}</p>
</div>
<div class="behavior pick" v-if="room.status">直播</div>
<div class="goto" @click="goto_live(room.id,room.name)"><img src="../static/images/arrow1.png" alt=""></div>
</div>
</div>
</div>
<script>
apiready = function(){
init();
new Vue({
el:"#app",
data(){
return {
rooms:[], // 房间列表
prev:{name:"",url:"",params:{}},
current:{name:"live",url:"live_list.html",params:{}},
}
},
created(){
this.get_room_list();
},
methods:{
get_room_list(){
var token = this.game.get("access_token") || this.game.fget("access_token");
this.axios.post("",{
"jsonrpc": "2.0",
"id": this.uuid(),
"method": "Live.stream.list",
"params": {}
},{
headers:{
Authorization: "jwt " + token,
}
}).then(response=>{
if(parseInt(response.data.result.errno)==1000){
this.rooms = response.data.result.stream_list;
}else{
this.game.print(response.data.result.errmsg);
}
}).catch(error=>{
// 网络等异常
this.game.print(error);
});
},
goto_live(room_id,stream_name){
// 进入房间
var pageParam = {
name: this.current.name,
url: this.current.url,
room_id: room_id,
stream_name: stream_name
}
this.game.goFrame("room","live.html",pageParam);
},
add_room(){ },
goto_home(){
// 退出当前页面
this.game.outWin("live");
},
}
});
}
</script>
</body>
</html>
前端获取后端传过来的直播流列表
3.创建房间
1.创建房间页面初始化:add_room.html
当用户点击创建房间时,会让用户输入房间名和房间密码
当用户输入后点击确定,会向后端接口发送请求,将用户输入的房间名和房间密码传递给后端
创建房间, add_room.html, 代码:
<!DOCTYPE html>
<html>
<head>
<title>创建房间</title>
<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">
<meta charset="utf-8">
<link rel="stylesheet" href="../static/css/main.css">
<script src="../static/js/vue.js"></script>
<script src="../static/js/axios.js"></script>
<script src="../static/js/main.js"></script>
<script src="../static/js/uuid.js"></script>
<script src="../static/js/settings.js"></script>
</head>
<body>
<div class="app frame avatar update_password" id="app">
<div class="box">
<p class="title">创建房间</p>
<img class="close" @click="close_frame" src="../static/images/close_btn1.png" alt="">
<div class="content">
<input class="password" type="text" v-model="name" placeholder="房间名称....">
<input class="password password2" type="password" v-model="password" placeholder="房间密码....">
</div>
<img @click="add_room_submit" class="btn" src="../static/images/yes.png" alt="">
</div>
</div>
<script>
apiready = function(){
init();
new Vue({
el:"#app",
data(){
return {
name:"",
password:"",
prev:{name:"",url:"",params:{}},
current:{name:"add_room",url:"add_room.html",params:{}},
}
},
methods:{
close_frame(){
this.game.outFrame("add_room");
},
add_room_submit(){
// 提交数据
var token = this.game.get("access_token") || this.game.fget("access_token");
this.axios.post("",{
"jsonrpc": "2.0",
"id": this.uuid(),
"method": "Live.stream",
"params": {
room_name: this.name,
password: this.password
}
},{
headers:{
Authorization: "jwt " + token,
}
}).then(response=>{
if(parseInt(response.data.result.errno)==1000){
this.rooms = response.data.result.stream_list;
}else{
this.game.print(response.data.result.errmsg);
}
}).catch(error=>{
// 网络等异常
this.game.print(error);
});
},
}
});
}
</script>
</body>
</html>
创建房间页面初始化:add_room.html
2.在直播流数据表中增加房间密码字段
服务端接口增加房间密码字段,live/models.py ,代码:
from application.utils.models import BaseModel,db
class LiveStream(BaseModel):
"""直播流管理"""
__tablename__ = "mf_live_stream"
name = db.Column(db.String(255), unique=True, comment="流名称")
room_name = db.Column(db.String(255), default="未命名",comment="房间名称")
room_password = db.Column(db.String(255), default="", comment="房间密码")
user = db.Column(db.Integer, comment="房主") class LiveRoom(BaseModel):
"""直播间"""
__tablename__ = "mf_live_room"
stream_id = db.Column(db.Integer, comment="直播流ID")
user = db.Column(db.Integer, comment="用户ID")
3.后端修改创建房间接口,新增验证密码功能
服务端创建房间接口, 新增密码字段并验证密码才可以进入房间
用户输入房间名和房间密码后,前端向后端发起请求,将输入内容提交给后端
后端接收到房间名和房间密码后,做如下几件事:
1.创建直播流:,mysql中存放:用户id/房间名/房间密码/直播流号
2.创建房间:mysql中存放:用户id/直播流号
live/views.py, 代码:
from application import jsonrpc,db
from message import ErrorMessage as message
from status import APIStatus as status
from flask_jwt_extended import jwt_required,get_jwt_identity
from application.apps.users.models import User
from .models import LiveStream,LiveRoom
from datetime import datetime
import random
@jsonrpc.method("Live.stream")
@jwt_required # 验证jwt
def live_stream(room_name,password):
"""创建直播流"""
current_user_id = get_jwt_identity() # get_jwt_identity 用于获取载荷中的数据
user = User.query.get(current_user_id)
if user is None:
return {
"errno": status.CODE_NO_USER,
"errmsg": message.user_not_exists,
}
# 申请创建直播流
stream = LiveStream.query.filter(LiveStream.user==user.id).first()
if stream is None:
stream_name = "room_%06d%s%06d" % (
user.id, datetime.now().strftime("%Y%m%d%H%M%S"), random.randint(100, 999999))
stream = LiveStream(
name=stream_name,
user=user.id,
room_name=room_name,
room_password=password
)
db.session.add(stream)
db.session.commit()
else:
stream.room_name = room_name
stream.room_password = password
db.session.commit() # 进入房间
room = LiveRoom.query.filter(LiveRoom.user==user.id,LiveRoom.stream_id==stream.id).first()
if room is None:
room = LiveRoom(
stream_id=stream.id,
user=user.id
)
db.session.add(room)
db.session.commit() return {
"errno": status.CODE_OK,
"errmsg": message.ok,
"data":{
"stream_name": stream.name,
"room_name": room_name,
"room_owner": user.id,
"room_id": "%04d" % stream.id,
}
} from .marshmallow import StreamInfoSchema
from flask import current_app
@jsonrpc.method("Live.stream.list")
@jwt_required # 验证jwt
def list_stream():
"""房间列表"""
current_user_id = get_jwt_identity() # get_jwt_identity 用于获取载荷中的数据
user = User.query.get(current_user_id)
if user is None:
return {
"errno": status.CODE_NO_USER,
"errmsg": message.user_not_exists,
"data": { }
} stream_list = LiveStream.query.filter(LiveStream.status==True, LiveStream.is_deleted==False).all()
sis = StreamInfoSchema()
data_list = sis.dump(stream_list,many=True) # 使用requests发送get请求
import requests
stream_response = requests.get(current_app.config["SRS_HTTP_API"]+"streams/")
client_response = requests.get(current_app.config["SRS_HTTP_API"]+"clients/")
import re,json
stream_text = re.sub(r'[^\{\}\/\,0-9a-zA-Z\"\'\:\[\]\._]', "", stream_response.text)
client_text = re.sub(r'[^\{\}\/\,0-9a-zA-Z\"\:\[\]\._]', "", client_response.text)
stream_dict = json.loads(stream_text)
client_dict = json.loads(client_text)
for data in data_list:
data["status"] = False
for stream in stream_dict["streams"]:
if data["name"] == stream["name"]:
data["status"] = stream["publish"]["active"]
break
data["clients_number"] = 0
for client in client_dict["clients"]:
if data["name"] == client["url"].split("/")[-1]:
data["clients_number"]+=1
if client["publish"] and "/live/"+data["name"]==client["url"]:
data["user"]["ip"] = client["ip"]
return {
"errno": status.CODE_OK,
"errmsg": message.ok,
"stream_list": data_list
}
服务端提供创建房间接口
4.前端判断房间是否存在密码,如存在密码必须正确输入密码才可进入房间
客户端中判定当房间存在密码时, 用户必须输入密码成功以后才可以进入房间, live_list.html代码:
<!DOCTYPE html>
<html>
<head>
<title>房间列表</title>
<meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no">

</div>
</div>
<script>
apiready = function(){
init();
new Vue({
el:"#app",
data(){
return {
rooms:[], // 房间列表
prev:{name:"",url:"",params:{}},
current:{name:"live",url:"live_list.html",params:{}},
}
},
created(){
this.get_room_list();
},
methods:{
get_room_list(){
var token = this.game.get("access_token") || this.game.fget("access_token");
this.axios.post("",{
"jsonrpc": "2.0",
"id": this.uuid(),
"method": "Live.stream.list",
"params": {}
},{
headers:{
Authorization: "jwt " + token,
}
}).then(response=>{
if(parseInt(response.data.result.errno)==1000){
this.rooms = response.data.result.stream_list;
}else{
this.game.print(response.data.result.errmsg);
}
}).catch(error=>{
// 网络等异常
this.game.print(error);
});
},
goto_live(room_id,stream_name,room_password){
// 验证密码
if(room_password != null){
api.prompt({
title:"请输入房间密码!",
buttons: ['确定', '取消'],
}, (ret, err)=>{
if( ret.text == room_password ){
this.goto_room(room_id,stream_name);
}else {
alert("密码错误!");
}
});
}else{
this.goto_room(room_id,stream_name);
}
},
goto_room(room_id,stream_name){
// 进入房间
var pageParam = {
name: this.current.name,
url: this.current.url,
room_id: room_id,
stream_name: stream_name
}
this.game.goFrame("room","live.html",pageParam);
},
add_room(){
this.game.goFrame("add_room","add_room.html",this.current,null,{
type:"push",
subType:"from_top",
duration:300
}); api.addEventListener({
name: 'add_room_success'
}, (ret, err)=>{
if( ret ){
this.game.print("创建房间成功");
}
}); },
goto_home(){
// 退出当前页面
this.game.outWin("live");
},
}
});
}
</script>
</body>
</html>
前端判断房间是否存在密码,如果存在密码,必须正确输入密码才可以进入房间
5.当用户点击返回键时,关闭推流
1.live_list.html
监听当前窗口下的任意一个帧页面点击返回键(keyback)的操作
当用户点击返回键的时候,告知(sendEvent)直播间关闭直播推流
