我有falcon应用程序,用gunicorn运行。如果.py文件中有错误,它会提供回溯,但在grunicorn中它只发送到控制台:
[2016-09-02 17:39:26 +0300] [6927] [INFO] Starting gunicorn 19.6.0
[2016-09-02 17:39:26 +0300] [6927] [INFO] Listening at: http://127.0.0.1:8000 (6927)
[2016-09-02 17:39:26 +0300] [6927] [INFO] Using worker: sync
[2016-09-02 17:39:26 +0300] [6930] [INFO] Booting worker with pid: 6930
唯一的错误输出是:
[2016-09-02 17:39:29 +0300] [6927] [INFO] Shutting down: Master
[2016-09-02 17:39:29 +0300] [6927] [INFO] Reason: Worker failed to boot.
如何获得完整的错误输出?我需要知道导致工人无法启动的原因。

这是gunicorn日志(不是猎鹰)的问题。有时它不会输出产生引导失败的异常。所以要调试我的WSGI app
我通常做的是使用wsgiref
提供的测试服务器运行服务器,如下所示:
from wsgiref import simple_server
if __name__ == '__main__':
APP_HOST = 8080 #you may want to change this
APP_HOST = '0.0.0.0' #you may want to change this
httpd = simple_server.make_server(APP_HOST, APP_PORT, app)
httpd.serve_forever()
这可以帮助您找出问题所在。
