我是编程初学者，我正在创建一个应用程序来使用 OpenStack 管理机器。但是，在尝试创建邮递员机器时，出现错误。
你可以帮帮我吗？
我的要求.txt：
Click==7.0
Flask==1.0.3
itsdangerous==1.1.0
Jinja2==2.10.1
MarkupSafe==1.1.1
Werkzeug==0.15.4
openstacksdk
来自 Github 教程的 python 代码：
from flask import Flask, request
from openstack import connection
from pprint import pprint
import json
import os
app = Flask(__name__)
# Source the openstack project rc file before running this app, to create the
# environment variables needed
conn = connection.Connection(auth_url=os.environ['OS_AUTH_URL'],
project_name=os.environ['OS_PROJECT_NAME'],
username=os.environ['OS_USERNAME'],
password=os.environ['OS_PASSWORD'],
user_domain_id="default",
project_domain_id=os.environ['OS_PROJECT_DOMAIN_ID'])
@app.route("/")
def hello():
return "Hello from Flask!"
@app.route("/list")
def list_openstack_resources():
# Check if connection is established
print("conn: ", conn)
# Print list of servers, images, flavors, endpoints, projects, users
server_list = list(conn.compute.servers())
image_list = list(conn.compute.images())
flavor_list = list(conn.compute.flavors())
project_list = list(conn.identity.projects())
user_list = list(conn.identity.users())
pprint(server_list)
pprint(image_list)
pprint(flavor_list)
pprint(project_list)
pprint(user_list)
return "List printed to stdout"
@app.route("/create_server")
def create_server():
# Check if connection is established
print("conn: ", conn)
# Create the volume first
volume_size = request.args.get('volume_size')
print("Starting to create volume with size (in GiB): ", volume_size)
volume = conn.create_volume(size=volume_size,
image="cirros-0.4.0-x86_64-disk",
wait=True,
bootable=False, #Or True
)
print("Created volume: ", json.dumps(volume))
# Create the server using the server_name parameter in the GET request
server_name = request.args.get('server_name')
print("Starting to create the server with name: ", server_name)
server = conn.create_server(name=server_name,
flavor="m1.micro",
terminate_volume=True,
timeout=180,
boot_volume=volume.id,
key_name="mayank-public-key",
)
print("Created server: ", json.dumps(server))
return "Server create request sent!"
if __name__ == "__main__":
app.run(debug=True, host='0.0.0.0', port=8080)
当我尝试这个时：
GET http://localhost:8080/create_server?server_name=server1&volume_size=2
我收到此错误：
