使用 cURL 的 Cisco ACI 身份验证不起作用

Question

I've been reading about Cisco ACI Automation with cURL here and trying to follow the same steps.

Unfortunately, the code doesn't work on cURL. I'm getting the following error.

C:\>curl -X POST -k https://x.x.x.x/api/aaaLogin.json -d '{"aaaUser":{"attributes":{"name":"user007","pwd":"password007"}}}'
{"totalCount":"1","imdata":[{"error":{"attributes":{"code":"400","text":"JSON parsing failed - incomplete attribute value at line: 1"}}}]}
C:\>

However, when I test the same code using Postman, it's working like a charm. What was wrong with the curl command?

Note: I did not put -c cookie.txt in this example as I'm getting the same error even if it's there.

Desired Output

Getting proper HTTP 200 response, not 400 Bad Request ..

Answer 1

You need first to login:

curl -X POST -k https://APIC_IP_ADDRESS/api/aaaLogin.xml -d '<aaaUser name="USERNAME" pwd="PASSWORD"/>' -c cookie.txt

The APIC controller returns a token stored in a cookie. It will last for 5 minutes. You must use this cookie to run any following REST API .

For example the REST API that creates a new Tenat, a new Application Profile and a new EPG will look like this:

curl -b cookie.txt -X POST -k https://APIC_IP_ADDRESS/api/node/mo/uni.xml -d '<polUni> <fvTenant name="TENANT-NAME" descr="TENANT-NAME-DESC" status=""> <fvAp name="APP-PROF-NAME">   <fvAEPg name="NEW-EPG-NAME" > </fvAEPg> </fvAp> </fvTenant> </polUni>' -c cookie.txt

You need to escape the double quotes (")

C:\>curl -X POST -k https://x.x.x.x/api/aaaLogin.json -d '{\"aaaUser\":{\"attributes\":{\"name\":\"user007\",\"pwd\":\"password007\"}}}'

In fact, you can even use the double quotes for user and password only:

C:\>curl -X POST -k https://x.x.x.x/api/aaaLogin.json -d '{aaaUser:{attributes:{name:\"user007\",pwd:\"password007\"}}}'

The reason you need to escape the \\" is because curl will remove them when constructing and sending the POST message. This is a capture from whireshark: whireshark capture
