如何解决将python日志记录添加到托管在docker上的FastApi端点上不会显示API端点日志
我有一个fastapi应用程序,要在上面添加python日志记录。我遵循了基本教程并添加了此内容,但是它并没有添加API,而只是添加了gunicorn日志记录。
因此,我有一个本地服务器使用docker build托管,因此要使用docker-compose up
运行服务器,并使用api客户端(失眠,类似于邮递员)测试我的端点。
下面是没有创建日志文件,因此也没有添加日志语句的代码。
我的项目str如下:
project/
src/
api/
models/
users.py
routers/
users.py
main.py
logging.conf
"""
main.py Main is the starting point for the app.
"""
import logging
import logging.config
from fastapi import FastAPI
from msgpack_asgi import MessagePackMiddleware
import uvicorn
from api.routers import users
logger = logging.getLogger(__name__)
app = FastAPI(debug=True)
app.include_router(users.router)
@app.get("/check")
async def check():
"""Simple health check endpoint."""
logger.info("logging from the root logger")
return {"success": True}
此外,我使用的是gunicorn.conf
,如下所示:
[program:gunicorn]
command=poetry run gunicorn -c /etc/gunicorn/gunicorn.conf.py foodgame_api.main:app
directory=/var/www/
autostart=true
autorestart=true
redirect_stderr=true
gunicorn.conf.py
和
import multiprocessing
bind = "unix:/tmp/gunicorn.sock"
workers = multiprocessing.cpu_count() * 2 + 1
worker_class = "uvicorn.workers.UvicornWorker"
loglevel = "debug"
errorlog = "-"
capture_output = True
chdir = "/var/www"
reload = True
reload_engine = "auto"
accesslog = "-"
access_log_format = '%(h)s %(l)s %(u)s %(t)s "%(r)s" %(s)s %(b)s "%(f)s" "%(a)s"'
这是我在docker上上述API端点的输出终端:
有人可以在这里指导我吗?我是FastApi的新手,所以将感谢您的帮助。
解决方法
我会使用 dict日志配置
按如下所示创建记录器配置,
# my_log_conf.py
log_config = {
"version": 1,"disable_existing_loggers": False,"formatters": {
"default": {
"()": "uvicorn.logging.DefaultFormatter","fmt": "%(levelprefix)s %(asctime)s %(message)s","datefmt": "%Y-%m-%d %H:%M:%S",},"handlers": {
"default": {
"formatter": "default","class": "logging.StreamHandler","stream": "ext://sys.stderr","loggers": {
"foo-logger": {"handlers": ["default"],"level": "DEBUG"},}
然后,使用 dictConfig
功能加载配置,
from logging.config import dictConfig
from fastapi import FastAPI
from some.where.my_log_conf import log_config
dictConfig(log_config)
app = FastAPI(debug=True)
注意:建议在 dictConfig(...)
初始化之前调用 FastAPI
函数。
初始化后,您可以在代码中的任何位置使用名为 foo-logger
的记录器,
import logging
logger = logging.getLogger('foo-logger')
logger.debug('This is test')
,
受到@JPG 答案的启发,但使用 pydantic 模型看起来更干净。
您可能希望公开更多变量。这个配置对我很有用。
library(baRcodeR)
library(dplyr)
example_labels <- uniqID_maker(user = FALSE,string = "Pool",level = 1:80,digits = 5)
example_labels_new <- example_labels %>% slice(rep(1:n(),each = 3))
write.csv(example_labels_new,file = "~/test.csv")
pdf_file_name <- tempfile()
custom_create_PDF(Labels = example_labels_new,name = "~/test",page_height = cm(29.7),page_width = cm(21),label_width = cm(4.826),label_height = cm(1.693),type = "linear",numrow = 16,numcol = 4,Fsz = 80,width_margin = cm(0.848),height_margin = cm(1.306),trunc = FALSE,Across = FALSE)
然后将其导入到您的
from pydantic import BaseModel
class LogConfig(BaseModel):
"""Logging configuration to be set for the server"""
LOGGER_NAME: str = "mycoolapp"
LOG_FORMAT: str = "%(levelprefix)s | %(asctime)s | %(message)s"
LOG_LEVEL: str = "DEBUG"
# Logging config
version = 1
disable_existing_loggers = False
formatters = {
"default": {
"()": "uvicorn.logging.DefaultFormatter","fmt": LOG_FORMAT,}
handlers = {
"default": {
"formatter": "default",}
loggers = {
"mycoolapp": {"handlers": ["default"],"level": LOG_LEVEL},}
文件中:
main.py
