我正在尝试WebRTC使用socket.io.

信令服务器是用 python 编写的，如下所示。

import socketio
import uvicorn
from starlette.applications import Starlette

ROOM = 'room'


sio = socketio.AsyncServer(async_mode='asgi', cors_allowed_origins='*')
star_app = Starlette(debug=True)
app = socketio.ASGIApp(sio, star_app)


@sio.event
async def connect(sid, environ):
    await sio.emit('ready', room=ROOM, skip_sid=sid)
    sio.enter_room(sid, ROOM)


@sio.event
async def data(sid, data):
    await sio.emit('data', data, room=ROOM, skip_sid=sid)


@sio.event
async def disconnect(sid):
    sio.leave_room(sid, ROOM)


if __name__ == '__main__':
    uvicorn.run(app, host='0.0.0.0', port=8003)

客户端看起来像这样

<script>
    const SIGNALING_SERVER_URL = 'http://127.0.0.1:8003?session_id=1';
    // WebRTC config: you don't have …

该项目使用了招摇。有以下代码。

@swagger_auto_schema(
        manual_parameters=[
            Parameter('download', IN_QUERY,
                      'Set `Content-Disposition=attachment` to make browser to download file'
                      'instead of showing it.',
                      type='bool'),
            Parameter('share_id', IN_PATH, type='uuid')
        ],
        security=[],
        responses={'400': 'Validation Error (e.g. base64 is wrong)',
                   '200': VideoSerializer}
    )

请解释每个论点的责任。我阅读了文档，但了解的很少......特别感兴趣'200': VideoSerializer

我是rest用 Flask写的flask-marshmallow

模型.py

class Application(db.Model):
    __tablename__ = 'applications'

    id = db.Column(db.String(), primary_key=True)
    name = db.Column(db.String())
    versions = db.relationship('Version', backref='application', lazy=True)

    def __repr__(self):
        return '<application {}>'.format(self.name)


class Version(db.Model):
    __tablename__ = 'versions'

    id = db.Column(db.String(), primary_key=True)
    file = db.Column(db.String(80), nullable=True)
    application_id = db.Column(db.Integer, db.ForeignKey('applications.id'))

谢马斯.py

class ApplicationDetailSchema(ma.Schema):
    class Meta:
        fields = ('id', 'name', 'versions')

路线.py

@bp.route("/<id>")
def application_detail(id):
    application = Application.query.get(id)
    result = application_detail_schema.dump(application)
    return jsonify(result)

类型错误：“版本”类型的对象不可 JSON 序列化

我执行此类请求： curl http://127.0.0.1:8000/api/v1/landing?param1=1&param2=2 结果，我只得到第一个参数。为什么会发生这种情况以及如何解决？
