PROSAGA码农传奇-IOT-使用WebSocket的AWS IoT MQTT：CERTIFICATE_VERIFY

我正在尝试使用此链接中提到的Python脚本设置AWS IoT ：我无需WebSocket（使用x.509证书）就可以在AWS IoT MQTT上进行连接。
<pre><code># creates the AWS IoT 
def createIoT(): 
 iot = AWSIoTMQTTShadowClient('AWSHome') 
 # update this with your own endpoint from the IOT dashboard 
 iot.configureEndpoint('allj.iot.reg.amazonaws.com', 443) 
 iot.configureCredentials('rootCA','private.key','certificate.crt') 
 iot.configureConnectDisconnectTimeout(10) # 10 sec 
 iot.configureMQTTOperationTimeout(5) # 5 sec 
 iot.connect() 
 return 
</code></pre>但是，当我尝试使用WebSocket在AWS IoT MQTT上进行连接时，出现以下错误：使用通过运行以下命令生成的证书：wget
<pre><code># creates the AWS IoT 
def createIoT(): 
 iot = AWSIoTMQTTShadowClient('AWSHome') 
 # update this with your own endpoint from the IOT dashboard 
 iot.configureEndpoint('asdasd.reg.amazonaws.com', 443) 
 iot.configureCredentials('VeriSign-Class%203-Public-Primary-Certification-Authority-G5.pem') 
 iot.configureConnectDisconnectTimeout(10) # 10 sec 
 iot.configureMQTTOperationTimeout(5) # 5 sec 
 iot.connect() 
 return 
</code></pre>错误：
<pre><code> Traceback (most recent call last):
