问题

原代码：

async def call_wss_api(msg):
    async with websockets.connect('wss://xxx.com/tool/handle') as websocket:
        await websocket.send(msg)
        response = ""
        count = 0
        while websocket.open:
            response = await websocket.recv()
    return response

执行代码时，发现会报错：ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)

Traceback (most recent call last):

ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)

进程已结束，退出代码为 1

解决方法

需要在调用函数websockets.connect()时，传递一个关键字参数ssl=ssl_context即可，代码如下：

import ssl
import certifi

ssl_context = ssl.create_default_context()
ssl_context.load_verify_locations(certifi.where())

async def call_wss_api(msg):
    async with websockets.connect('wss://xxx.com/tool/handle', ssl=ssl_context) as websocket:
        await websocket.send(msg)
        response = ""
        count = 0
        while websocket.open:
            response = await websocket.recv()
    return response
