Sentry：限制速率错误以防止错误配额的耗尽

使用Sentry的Rate Limiting（速率限制）功能，可以控制发送到Sentry的错误速率，以防止在一段时间内错误配额被用尽。可以使用Sentry的API触发速率限制并编写代码来处理速率限制错误。

以下是使用Python的示例代码：

import sentry_sdk
from sentry_sdk import capture_exception
from sentry_sdk.transport import Transport
from sentry_sdk.utils import MAX_INT

class RateLimitedTransport(Transport):
    """
    Transport class that handles rate limiting exceptions
    """
    def __init__(self, *args, **kwargs):
        Transport.__init__(self, *args, **kwargs)
        self.quota_remaining = MAX_INT
        self.quota_limit = MAX_INT

    def send_event(self, event):
        if self.quota_remaining == 0:
            raise RateLimitError("Rate limit exceeded")

        try:
            response = super(RateLimitedTransport, self).send_event(event)
            self.quota_remaining = int(response.headers.get('X-Sentry-Rate-Limits', '0;').split(';')[0])
            self.quota_limit = int(response.headers.get('X-Sentry-Rate-Limits', '0;').split(';')[1])
            return response
        except RateLimitError as e:
            raise e
        except Exception as e:
            self.quota_remaining = 0
            self.quota_limit = 0
            raise TransportError(repr(e))

    def send(self, data, headers):
        if self.quota_remaining == 0:
            raise RateLimitError("Rate limit exceeded")

        try:
            response = super(RateLimitedTransport, self).send(data, headers)
            self.quota_remaining = int(response.headers.get('X-Sentry-Rate-Limits', '0;').split(';')[0])
            self.quota_limit = int(response.headers.get('X-Sentry-Rate-Limits', '0;').split(';')[1])
            return response
        except RateLimitError as e:
            raise e
        except Exception as e:
            self.quota_remaining = 0
            self.quota_limit = 0
            raise TransportError(repr(e))

# Configure the Sentry SDK to use our custom transport
sentry_sdk.init(
    dsn="YOUR DSN HERE",
    transport=RateLimitedTransport,
)

此示例代码会设置一个名为RateLimitedTransport的自定义传输类，该传输类处理速率限制异常。示例代码还演示了如何使用该传输类来初始化Sentry SDK。
