在生产环境中使用uWSGI来运行Flask应用

安装uwsgi

bash 复制代码

pip install uwsgi -i https://pypi.tuna.tsinghua.edu.cn/simple

安装不上则使用以下命令：

bash 复制代码

conda install -c conda-forge uwsgi

当您成功安装uwsgi后，您可以通过以下步骤来测试uwsgi是否安装成功：

创建一个Python脚本，例如app.py，其中包含以下内容：

python 复制代码

def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"]

在终端中，使用以下命令启动uwsgi服务器：

bash 复制代码

uwsgi --http :8000 --wsgi-file app.py

如果一切顺利，您将看到类似以下的输出：

bash 复制代码
