【Python】【Websocket】Python实现websocket客户端高并发压测

WebSocket压测，可以使用Jmeter方式，也可以使用Python代码直接压测

import websocket
import time
import threading

SERVER_URL = "ws://192.168.1.208:7600/box/reader-"
def on_message(ws, message):
    print(message)


def on_error(ws, error):
    print(error)


def on_close(ws):
    print("### closed ###")


def on_open(ws):
    def send_trhead():
        send_info = {
        "store_id": "0001",
            "msg_type":"pay_info",
        "device_id": "device_001",
        "pay_code": "ffe2sdfdf-8sdfew-sdfsdf-ijlkj",
        "goods": [
            "C004-SD343-234",
            "D004-GE343-990",
            "G004-X343-452"
        ]
        }
        while True:
            time.sleep(5)
            ws.send(json.dumps(send_info))


    t = threading.Thread(target=send_trhead)
    t.start()




def on_start(a):
    time.sleep(a%20)
    websocket.enableTrace(True)
    ws = websocket.WebSocketApp(SERVER_URL + str(a),
                                on_message=on_message,
                                on_error=on_error,
                                on_close=on_close)
    ws.on_open = on_open
    ws.run_forever()




from threadpool import ThreadPool, makeRequests
if __name__ == "__main__":
    init_logging()
    pool = ThreadPool(5000)
    test = list()
    for ir in range(5000):
        test.append(ir)
    requests = makeRequests(on_start, test)
    [pool.putRequest(req) for req in requests]
    pool.wait()

# 同时5000个连接，每个连接5秒发一次数据
# 如果需用作socket client的测试，直接修改启动连接的函数为socket连接方式

前提需要安装相关依赖库

pip install websocket
pip install threadpool
pip install websocket-client
pip install multiprocessing

脚本如下，参考，也可以参考其github：
