在烧瓶上使用旋转式原木

Question

这是我的代码： 这在flask和python 3.0中只是一个概念上的证明

from flask import Flask
from flask import request
from flask import jsonify
from flask_cors import CORS
import linecache
import json
import time
import logging
from logging.handlers import RotatingFileHandler

logger.setLevel(logging.DEBUG)

formatter = logging.Formatter('%(asctime)s :: %(levelname)s :: %(message)s')

file_handler = RotatingFileHandler('../productpicapi.log', 'a', 1000000, 1)

file_handler.setLevel(logging.DEBUG)
file_handler.setFormatter(formatter)
logger.addHandler(file_handler)

stream_handler = logging.StreamHandler()
stream_handler.setLevel(logging.DEBUG)
logger.addHandler(stream_handler)

def PrintException():
    exc_type, exc_obj, tb = sys.exc_info()
    f = tb.tb_frame
    lineno = tb.tb_lineno
    filename = f.f_code.co_filename
    linecache.checkcache(filename)
    line = linecache.getline(filename, lineno, f.f_globals)
    return 'EXCEPTION IN ({}, LINE {} "{}"): {}'.format(
        filename, lineno, line.strip(), exc_obj
    )


app = Flask(__name__)
cors = CORS(app, resources={r"/*": {"origins": "*"}})
app.logger = logger


@app.route("/productPicApi/v1/productPicture", methods=["POST"])
def savePicture():
    logger.info("inside productpic api")
    try:
        try :
            document = request.form
            document = json.loads(document["json"])
            logger.info("inside android")
            return  jsonify({"STATUS": "OK"})
        except:
            logger.info("inside ios")
            document = request.get_json()
            r = requests.post(productPictureEndpointUrl, json=document)
            array = r.json()
            logger.info("return productpic micro")
            logger.info(array)
            return jsonify(array)
        return jsonify({"STATUS": "KO"})
    except Exception as e:
        print("error")
        print(e)
        return jsonify(
            {
                "STATUS": "KO",
                "EXCEPTION": PrintException() + " " + str(e),
                "DOCUMENT": document,
                "ORIGIN": "ProductPicApi",
            }
        )

if __name__ == "__main__":
    logger.info("productPictureEndpointUrl")
    app.run(host="0.0.0.0", port=portPicApi,debug=True)

但是日志文件为空，是的，我已经检查了上面的目录。 为什么不将其写入日志文件？ 通常，它至少应该写入文件中的某些内容... 通常记录器应该执行此操作吗？ 有没有办法在烧瓶中使用旋转式原木？ 长颈瓶能抓住我的记录仪吗？
