logging 日志完整应用实例
日志文件函数：日志相关设置
logfile.py
import logging
def logg():
# LOG_FORMAT = "%(asctime)s - %(levelname)s - %(message)s"
LOG_FORMAT = "%(asctime)s - %(levelname)s - %(filename)s, line:%(lineno)d - %(message)s" # 带有文件名、行号
DATE_FORMAT = "%Y-%m-%d %H:%M:%S"
logger = logging.getLogger()
logger.setLevel(logging.DEBUG) #这里设置日志的级别
# 输出到文件
file_handler = logging.FileHandler("all.log", mode='a', encoding='utf-8')
# 输出到控制台
stream_handler = logging.StreamHandler()
# 错误日志单独输出到一个文件
error_handler = logging.FileHandler('error.log', mode='a', encoding='utf-8')
error_handler.setLevel(logging.ERROR) #注意这里，错误日志只记录ERROR级别的日志
# 将所有的处理器加入到logger中
logger.addHandler(file_handler)
logger.addHandler(stream_handler)
logger.addHandler(error_handler)
formatter = logging.Formatter(fmt=LOG_FORMAT, datefmt=DATE_FORMAT)
# 设置格式化
file_handler.setFormatter(formatter)
stream_handler.setFormatter(formatter)
error_handler.setFormatter(formatter)
logger.info('info级别的')
logger.error('error级别')
logger.debug('debug级别')
logger.warning('warning级别')
logg()
应用用文件uploadAPI.py调用日志文件方法
uploadAPI.py
from flask import Flask, jsonify , request,render_template,redirect,url_for

filemode='w', format='[%(asctime)s] [%(levelname)s] >>> %(message)s',

)'''

@app.route('/')
def index():
return render_template('upload.html')
@app.route('/center/upload',methods=['POST'])#对应表单里面的action="/upload"
def center():
if "file" not in request.files: #"file" 对应前端upload.html 中的name
return redirect(request.url)#redirect 重定向新的地址
file = request.files.get('file') # 获取文件
if not file :#如果文件为空
return "请选择文件"
if not allowed_file(file.filename): #如果不是传入的指定格式文件。重定向到当前url
#return redirect(request.url)

filename = secure_filename(file.filename) # 用这个函数确定文件名称是否是安全
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename)) # 保存文件 os.path.join把目录和文件名合成一个路径
return redirect(url_for('show', filename=filename))
# 展示
@app.route('/show/' )
def show(filename):
# send_from_directory可以从目录加载文件
return send_from_directory(app.config['UPLOAD_FOLDER'], filename)
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000, debug=True)
