azure应用程序中应用程序的ajax请求出现错误

问题描述 投票：0回答：1

我在 python-django 中有一个应用程序，在本地主机上一切正常。我正确地向 Python 发出 ajax 请求，但它在 Azure 应用程序中不起作用，请按照我如何发出请求的示例代码进行操作：

 $.ajax({
                url: '/PlanEx/DCC/GerarTabelaAnova',
                data: formData,
                type: 'POST',

此外，我的网关应用程序经常超时

我尝试将一个简单的 Django 项目（其中包含 AJAX POST 请求）部署到 Azure 应用服务，没有任何问题。

这是我的项目结构

在将应用程序部署到 azure 应用程序服务之前创建一个requirements.txt 文件

要生成 

requirements.txt
文件，您可以在终端中使用以下命令。

pip freeze > requirements.txt

本地输出：

这是部署后的输出：
