Python中如何使用Sentry进行错误日志聚合？

# 安装Sentry SDK
# pip install sentry-sdk

import sentry_sdk
from sentry_sdk.integrations.flask import FlaskIntegration
from sentry_sdk.integrations.django import DjangoIntegration
import logging

# 基础配置示例
def setup_sentry_basic():
    sentry_sdk.init(
        dsn="https://your-public-key@sentry.io/your-project-id",  # 从Sentry控制台获取
        traces_sample_rate=1.0,  # 性能监控采样率
        environment="production",  # 环境标识
    )
    
# Flask应用集成示例
def setup_sentry_flask():
    sentry_sdk.init(
        dsn="YOUR_DSN_HERE",
        integrations=[FlaskIntegration()],
        traces_sample_rate=1.0
    )
    
    from flask import Flask
    app = Flask(__name__)
    
    @app.route('/error')
    def trigger_error():
        division_by_zero = 1 / 0  # 这会被Sentry捕获
        return "This won't be reached"
    
    return app

# Django集成（在settings.py中添加）
"""
import sentry_sdk
from sentry_sdk.integrations.django import DjangoIntegration

sentry_sdk.init(
    dsn="YOUR_DSN_HERE",
    integrations=[DjangoIntegration()],
    traces_sample_rate=1.0,
    send_default_pii=True  # 是否发送用户信息
)
"""

# 手动捕获异常示例
def manual_capture():
    try:
        risky_operation()
    except Exception as e:
        sentry_sdk.capture_exception(e)
        print("错误已发送到Sentry")

# 记录自定义消息
def log_custom_message():
    sentry_sdk.capture_message("发生了自定义业务异常", level="error")

# 添加用户上下文
def set_user_context():
    sentry_sdk.set_user({"email": "user@example.com", "id": "12345"})

# 添加额外标签
def add_tags():
    with sentry_sdk.configure_scope() as scope:
        scope.set_tag("page_locale", "zh-cn")
        scope.set_tag("business_unit", "payment")

# 与Python logging集成
def integrate_with_logging():
    sentry_sdk.init(dsn="YOUR_DSN_HERE")
    
    logger = logging.getLogger(__name__)
    handler = sentry_sdk.integrations.logging.EventHandler()
    logger.addHandler(handler)
    
    # 现在logging.error()会自动发送到Sentry
    logger.error("通过logging模块记录的错误")

# 测试配置是否生效
def test_sentry():
    setup_sentry_basic()
    
    # 测试异常捕获
    try:
        result = 1 / 0
    except ZeroDivisionError as e:
        sentry_sdk.capture_exception(e)
        print("测试异常已发送")
    
    # 测试自定义消息
    sentry_sdk.capture_message("Sentry配置测试", level="info")

if __name__ == "__main__":
    test_sentry()

核心步骤：

1. 注册Sentry账号并创建项目，获取DSN
2. 安装SDK：pip install sentry-sdk
3. 在应用初始化时调用sentry_sdk.init()配置DSN
4. 添加对应的框架集成（Flask/Django等）
5. 自动捕获未处理异常，或使用capture_exception()手动捕获

配置建议：根据环境设置不同的DSN和采样率。
