要通过Apache Atlas访问创建词汇表、术语、分类和分类的功能,可以使用Apache Atlas的REST API进行操作。以下是一个使用Python编写的示例代码:
import requests
import json
# Apache Atlas的基本信息
atlas_host = "http://localhost:21000"
atlas_username = "admin"
atlas_password = "admin"
# 登录Apache Atlas获取令牌
def get_auth_token():
url = f"{atlas_host}/api/atlas/v2/login"
headers = {"Content-Type": "application/json"}
data = {
"username": atlas_username,
"password": atlas_password
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 200:
return response.json()["token"]
else:
raise Exception("Failed to get authentication token")
# 创建词汇表
def create_glossary():
url = f"{atlas_host}/api/atlas/v2/glossary"
headers = {"Content-Type": "application/json", "Authorization": f"Bearer {get_auth_token()}"}
data = {
"name": "My Glossary",
"shortDescription": "This is a sample glossary",
"longDescription": "This glossary contains terms and classifications"
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 201:
return response.json()["guid"]
else:
raise Exception("Failed to create glossary")
# 创建术语
def create_term(glossary_guid):
url = f"{atlas_host}/api/atlas/v2/glossary/{glossary_guid}/terms"
headers = {"Content-Type": "application/json", "Authorization": f"Bearer {get_auth_token()}"}
data = {
"name": "Sample Term",
"description": "This is a sample term",
"glossaryGuid": glossary_guid
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 201:
return response.json()["guid"]
else:
raise Exception("Failed to create term")
# 创建分类
def create_category(glossary_guid):
url = f"{atlas_host}/api/atlas/v2/glossary/{glossary_guid}/categories"
headers = {"Content-Type": "application/json", "Authorization": f"Bearer {get_auth_token()}"}
data = {
"name": "Sample Category",
"description": "This is a sample category",
"glossaryGuid": glossary_guid
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 201:
return response.json()["guid"]
else:
raise Exception("Failed to create category")
# 示例用法
glossary_guid = create_glossary()
term_guid = create_term(glossary_guid)
category_guid = create_category(glossary_guid)
print(f"Created glossary with GUID: {glossary_guid}")
print(f"Created term with GUID: {term_guid}")
print(f"Created category with GUID: {category_guid}")
请注意,上述代码中使用的atlas_host
,atlas_username
和atlas_password
变量需要根据实际情况进行修改。此外,代码中的create_glossary
,create_term
和create_category
函数分别用于创建词汇表、术语和分类,可以根据需要进行修改和扩展。
