BASH中的自动化-在AWS-IoT中创建事物。如何在创建thingId后检索它？

Question

这是我们在AWS中使用BASH脚本创建一个东西的时候。它工作得很好，但我想检索thing_ID并将其存储在一个变量中。

下面是创建这个东西的bash代码。这是蚊子mosquitto_pub --cafile root.cert --cert deviceCertAndCACert.crt --key deviceCert.key -h xxxxx.iot.us-east-2.amazonaws.com -p 8883 -q 1 -t foo/bar -I anyclientID --tls-version tlsv1.2 -m "Hello" -d的第一次调用，但在第一个连接中它只返回：

Client anyclientID18351 sending CONNECT
Error: The connection was lost.

如何在创建thing_Id后检索它？

代码如下：

openssl genrsa -out deviceCert.key 2048
openssl req -new -key deviceCert.key -out deviceCert.csr -subj "/C=CA/ST=ON/L=NY/O=SC/OU=DG/CN=EX"
openssl x509 -req -in deviceCert.csr -CA rootCA.pem -CAkey rootCA.key -CAcreateserial -out deviceCert.crt -days 365 -sha256
cat deviceCert.crt rootCA.pem > deviceCertAndCACert.crt
wget https://www.symantec.com/content/en/us/enterprise/verisign/roots/VeriSign-Class%203-Public-Primary-Certification-Authority-G5.pem
mv VeriSign-Class\ 3-Public-Primary-Certification-Authority-G5.pem root.cert
mosquitto_pub --cafile root.cert --cert deviceCertAndCACert.crt --key deviceCert.key -h xxxxx.iot.us-east-2.amazonaws.com -p 8883 -q 1 -t foo/bar -I anyclientID --tls-version tlsv1.2 -m "Hello" -d
mosquitto_pub --cafile root.cert --cert deviceCertAndCACert.crt --key deviceCert.key -h xxxxx.iot.us-east-2.amazonaws.com -p 8883 -q 1 -t foo/bar -I anyclientID --tls-version tlsv1.2 -m "Thing $i is Working" -d

Answer 1

如果您知道对象的名称，则可以在命令行界面中使用describe-thing命令。

aws iot describe-thing --thing-name ENTER_THING_NAME_HERE

响应：

{
    "defaultClientId": "anyclientID",
    "thingName": "THING_NAME",
    "thingId": "40da2e73-c6af-406e-b415-15acae538797",
    "thingArn": "arn:aws:iot:us-east-2:123456789012:thing/THING_NAME",
    "thingTypeName": "LightBulb",
    "attributes": {
        "model": "123",
        "wattage": "75"
    },
    "version": 1
