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
