我正在撰寫一個 python 腳本來轉換一些 Curl 命令，以便可以使用 python 的 requests 模塊中的方法呼叫它們，但是我遇到了一些錯誤。
這是 curl 命令塊：
export NEXRAN_XAPP=`sudo kubectl get svc -n ricxapp --field-selector metadata.name=service-ricxapp-nexran-rmr -o jsonpath='{.items[0].spec.clusterIP}'`
curl -i -X PUT -H "Content-type: application/json" -d '{"allocation_policy":{"type":"proportional","share":1024}}' http://${NEXRAN_XAPP}:8000/v1/slices/slow
curl -i -X PUT -H "Content-type: application/json" -d '{"allocation_policy":{"type":"proportional","share":256}}' http://${NEXRAN_XAPP}:8000/v1/slices/fast
這是我撰寫的名為“change_slice_allocation.py”的python腳本：
import requests
import os
os.system ("export NEXRAN_XAPP=`kubectl get svc -n ricxapp --field-selector metadata.name=service-ricxapp-nexran-rmr -o jsonpath='{.items[0].spec.clusterIP}'`")
headers = {
'Content-type': 'application/json',
}
data1 = '{"allocation_policy":{"type":"proportional","share":1024}}'
data2 = '{"allocation_policy":{"type":"proportional","share":256}}'
response1 = requests.put('http://${NEXRAN_XAPP}:8000/v1/slices/fast', headers=headers, data=data1)
response2 = requests.put('http://${NEXRAN_XAPP}:8000/v1/slices/slow', headers=headers, data=data2)
我收到以下錯誤：

我是 curl 命令的新手。任何人都可以幫助我進行正確的轉換嗎？謝謝。

這是您發布的兩個 curl 命令的轉換。
我使用將 curl 命令轉換為 Python
import requests
headers = {
# Already added when you pass json=
# 'Content-type': 'application/json',
}
json_data = {
'allocation_policy': {
'type': 'proportional',
'share': 1024,
},
}
response = requests.put('http://NEXRAN_XAPP:8000/v1/slices/slow', headers=headers, json=json_data)
import requests
headers = {
# Already added when you pass json=
# 'Content-type': 'application/json',
}
json_data = {
'allocation_policy': {
'type': 'proportional',
'share': 256,
},
}
response = requests.put('http://NEXRAN_XAPP:8000/v1/slices/fast', headers=headers, json=json_data)
