求助：使用Atlassian Python API获取史诗关联任务遇400错误，求可行代码

一、Atlassian Python API 实现 #

核心问题修正 #

之前的400错误主要源于两个问题：

• get_issues_for_epic的epic_id参数需要史诗的内部数字ID，而非史诗key（如EPIC-123）
• Cloud版Jira认证优先使用API Token，而非用户密码，密码认证可能引发权限或参数解析错误

可行代码 #

import os
from atlassian import Jira

# 初始化Jira Cloud客户端
jira = Jira(
    url=os.getenv('JIRA_URL'),  # 格式示例：https://your-domain.atlassian.net
    username=os.getenv('JIRA_USERNAME'),
    password=os.getenv('JIRA_API_TOKEN'),  # 替换为Atlassian账户生成的API Token
    cloud=True
)

# 方式1：用JQL查询（无需看板ID，兼容性更强）
epic_key = "EPIC-123"  # 替换为你的史诗key
jql = f'"Epic Link" = "{epic_key}"'
issues_result = jira.jql(jql)

# 遍历输出关联任务
for issue in issues_result['issues']:
    print(f"任务Key: {issue['key']}, 标题: {issue['fields']['summary']}")

# 方式2：修复get_issues_for_epic参数（需看板ID和史诗内部ID）
# 先获取史诗的内部ID
epic_detail = jira.issue(epic_key)
epic_internal_id = epic_detail['id']
board_id = 1  # 替换为史诗所属的看板ID

epic_issues = jira.get_issues_for_epic(board_id=board_id, epic_id=epic_internal_id)
for issue in epic_issues:
    print(f"任务Key: {issue['key']}, 标题: {issue['fields']['summary']}")

二、REST API 实现 #

Curl 命令 #

curl -X GET \
  "https://your-domain.atlassian.net/rest/api/3/search?jql=%22Epic%20Link%22%20%3D%20%22EPIC-123%22" \
  -u "your-email@example.com:your-api-token"

Python Requests 实现 #

import os
import requests

jira_url = os.getenv('JIRA_URL') + "/rest/api/3/search"
auth = (os.getenv('JIRA_USERNAME'), os.getenv('JIRA_API_TOKEN'))
query_params = {
    'jql': f'"Epic Link" = "{epic_key}"'
}

response = requests.get(jira_url, auth=auth, params=query_params)
response.raise_for_status()  # 捕获HTTP错误
issues_data = response.json()

for issue in issues_data['issues']:
    print(f"任务Key: {issue['key']}, 标题: {issue['fields']['summary']}")

注意事项 #

• API Token需在Atlassian账户设置中生成：头像 → 个人设置 → 安全 → API tokens
• 确保当前用户拥有该史诗及关联任务的访问权限
• JQL中的字段名需与你的Jira实例一致，若自定义过史诗关联字段，需替换为实际字段键
