Question

有问题的应用程序使用包含瓶子的connexion来处理Web服务器。使用swagger指定API。是否有一种简单直接的方法可以从代码中获取从Web服务器生成http响应的代码？

如果可能的话，我想避免写200个错误处理程序，或者最流行的10个错误处理程序。

api.py

import connexion
app = connexion.App(__name__,
                specification_dir='../swagger/',
                swagger_ui=False,
                validator_map={
                    'body': connexion.decorators.validation.RequestBodyValidator
                })
app.add_api('swagger.yml', strict_validation=True)

# If I had to use app.error_handler decorators to implement the special
# treatment of http responses with error codes, I would put it here

swagger.yml

      responses:

          description: Success!
          schema:
            $ref: '#/definitions/Response'
        '400':
          description: Error!
          schema:
            $ref: '#/definitions/Response'
        '403':
          description: Not Authorized
          schema:
            $ref: '#/definitions/Response'    
# a lot more stuff and "definitions"

我通过继承Flask对象解决了这个问题，正如davidism建议的那样。简短的版本是：

<强> app.py

import logging.config
import yaml

logging.config.dictConfig(yaml.load(open('logging.conf', 'r')))
logger = logging.getLogger("mainLogger")


class LoggingFlask(Flask):
    def make_response(self, rv):
        rv = super(LoggingFlask, self).make_response(rv)
        if int(rv.status_code) >= 300:
            logger.warn("Request failed with error code %s." % rv.status_code)
        return rv


app = LoggingFlask(__name__)

<强> SESSION.LOG

如果有人知道如何访问触发当前响应的请求，请随时删除评论，以便我也可以将其包含在此答案中。

记录所有http响应，错误代码＆gt; = 400
