[英]How to get schema from confluent schema registry with schema id and version using python
[英]How to programmatically get schema from confluent schema registry in Python
截至目前,我正在做類似這樣的閱讀 avsc 文件以獲取架構
value_schema = avro.load('client.avsc')
我可以做些什么來使用主題名稱從融合模式注冊表中獲取模式嗎?
我找到了一種方法,但不知道如何使用它。
https://github.com/marcosschroh/python-schema-registry-client
from confluent_kafka.avro.cached_schema_registry_client import CachedSchemaRegistryClient
sr = CachedSchemaRegistryClient({
'url': 'http://localhost:8081',
'ssl.certificate.location': '/path/to/cert', # optional
'ssl.key.location': '/path/to/key' # optional
})
value_schema = sr.get_latest_schema("orders-value")[1]
key_schema= sr.get_latest_schema("orders-key")[1]
按主題名稱獲取模式
from schema_registry.client import SchemaRegistryClient
sr = SchemaRegistryClient('localhost:8081')
my_schema = sr.get_schema(subject='mySubject', version='latest')
通過 ID 獲取架構
from schema_registry.client import SchemaRegistryClient
sr = SchemaRegistryClient('localhost:8081')
my_schema = sr.get_by_id(schema_id=1)
我喜歡這個它對我有用
import requests
import os
SCHEMA_REGISTRY_URL = os.getenv('SCHEMA_REGISTRY_URL');
print("SCHEMA_REGISTRY_URL: ", SCHEMA_REGISTRY_URL)
URL = SCHEMA_REGISTRY_URL + '/subjects/' + topic + '/versions/latest/schema'
r = requests.get(url=URL)
schema = r.json()
print("Schema From Schema Registry ==========================>>")
print("Schema: ", schema)
您可以使用get_latest_version
函數來獲取架構信息
from confluent_kafka.schema_registry import SchemaRegistryClient sr = SchemaRegistryClient({"url": 'http://localhost:8081'}) subjects = sr.get_subjects() for subject in subjects: schema = sr.get_latest_version(subject) print(schema.version) print(schema.schema_id) print(schema.schema.schema_str)
