Case 1: Capture the packet to construct the url of the new cloud host (instance)
1. Wireshark opens the network card to capture vmware vmnet8, and the filter condition tcp.port == 8774 && http.request.method == POST starts!
2. Create a new instance named wireshark on the 
web 3. Filter condition tcp.port == 8774 && http.request.method == POST has data, open this http stream, the picture is as follows:
POST /v2.1/c0e784c602af4b40933a78bc3dcda542/servers HTTP/1.1

Based on the above information, construct an api url and use this url to construct the second virtual machine wireshark2. The api url I constructed is as follows:
curl -X POST -H "Content-Type: application/json" -H "X- the Token-auth: gAAAAABfol5E8fphn3g-q4zoqt089FHoSefQL1OFeTIg6JqFPvB53mHZMX6-qPK0pNYYa0ce86z_3g_yNNEWh2HlkEVaZq16CIC6MmVcQeyTy69fpRlOYfZp90-FiEDiHFQlPMPoZlDb0yrhraaxKPW4jck9cbzAltnTCYkd8IEfu2R8JYFG0kBuZmQp-1-8Ksd_ZwQQS8O0 "-d '

}]
}
}' http://controller:8774/v2.1/c0e784c602af4b40933a78bc3dcda542/servers
After that, the virtual machine was successfully created! (Note that the formatted json string is replaced by a space with a text tool before the cli is executed!)
Case 2: Capture the packet to construct the url to delete the cloud host (instance)
(2) Delete the host capture packet to get the api
capture filter condition is tcp.port == 8774 && http.request.method == DELETE to
obtain the packet capture information as follows:
DELETE /v2.1/c0e784c602af4b40933a78bc3dcda542/servers/e22e0fd1-44e2-487d-a37c-5d36c721ec1b HTTP/1.1

The following is what I built from the above package!

Case 3: Capture packets to construct URLs for deleting volumes, deleting mirrors, etc. can be obtained in a similar way.
In addition, the token can also be captured first like the teacher and stored using the $token variable to directly reference, so there is no need to write so long.
I'll add it tomorrow
(3) Delete a volume to capture packets to get api
tcp.port == 8776 && http.request.method == DELETE
(4) New volume
tcp.port == 8776 && http.request.method == POST
