Question

我通过GitHub将本地开发的Django Web应用程序部署到Azure中，当我尝试运行URL时，在web.config文件中收到以下错误

 Error occurred while reading WSGI handler:

这是我的web.config文件：

我的代码是否有问题，还是需要安装一些其他要求？尝试在Azure中运行django Web应用程序时出现错误，在本地运行我的Web应用程序时运行正常。

RuntimeError：populate（）不能重入

我将django应用程序部署为天蓝色，但没有重现您的问题。据我所知，这意味着配置之一不正确或缺少必需的库，它将引起此填充错误。

我建议您将以下代码添加到wsgi.py文件中，并记录真正的错误，然后可以进行检查。

import os
import time
import traceback
import signal
import sys
from django.core.wsgi import get_wsgi_application

try:
    application = get_wsgi_application()
    print 'WSGI without exception'
except Exception:
    print 'handling WSGI exception'
    # Error loading applications
    if 'mod_wsgi' in sys.modules:
        traceback.print_exc()
        os.kill(os.getpid(), signal.SIGINT)
        time.sleep(2.5)

更多解决方案，请参考以下主题：

1。Django populate() isn't reentrant

2。Django stops working with RuntimeError: populate() isn't reentrant

希望它对您有帮助。

django web-config azure给出错误“ RuntimeError：populate（）不重入”
