如何使用Python Rally API获取给定缺陷的讨论

import requests
import json

api_key = "YOUR_API_KEY"
workspace = "YOUR_WORKSPACE"
project = "YOUR_PROJECT"
defect_id = "DEFECT_ID"

url = f"https://rally1.rallydev.com/slm/webservice/v2.0/defect/{defect_id}?fetch=Discussion"
headers = {
    "ZSESSIONID": api_key,
    "Content-Type": "application/json"
}

response = requests.get(url, headers=headers)

if response.status_code == 200:
    data = json.loads(response.text)
    discussions = data["Defect"]["Discussion"]["Comments"]
    for discussion in discussions:
        print(discussion["Text"])
else:
    print("Failed to retrieve discussions.")
