一、在线安装docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum -y install docker-ce
systemctl daemon-reload && systemctl restart docker

二、安装python3以及依赖包

yum install python36

pip3.6 install websocket_client

三、运行kong网关

docker run -d --name kong \
    -e "KONG_DATABASE=off" \
    -e "KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl" \
    -p 8000:8000 \
    -p 8443:8443 \
    -p 8001:8001 \
    -p 8444:8444 \
    kong

四、网关上注册websocket接口

websocket server online: ws://123.207.136.134:9010/ajaxchattest

cat > apis.yaml <<EOF
_format_version: "1.1"
services:
 - name: websocket-service
   url: http://123.207.136.134:9010
   routes:
   - name: websocket-route
     paths:
     - /
EOF

curl -F "config=@apis.yaml" http://127.0.0.1:8001/config

五、客户端测试

其中127.0.0.1:8000是Kong网关的数据口

cat > client.py <<EOF
#!/usr/bin/env python3

from websocket import create_connection

ws = create_connection("ws://127.0.0.1:8000/ajaxchattest")
print("Sending 'Hello, World 1'...")
ws.send("Hello, World 1")
print("Sent")
print("Receiving...")
result =  ws.recv()
print("Received '%s'" % result)

print("Sending 'Hello, World 2'...")
ws.send("Hello, World 2")
print("Sent")
print("Receiving...")
result =  ws.recv()
print("Received '%s'" % result)

print("Sending 'Hello, World 3'...")
ws.send("Hello, World 3")
print("Sent")
print("Receiving...")
result =  ws.recv()
print("Received '%s'" % result)

ws.close()
EOF

chmod +x client.py

./client.py
