Python 3.x 使用TCHA时uWSGI分段错误

我在我的服务器（Ubuntu18.04.2 LTS）上使用Tcha功能时遇到问题。在我的本地机器上，一切正常，但当我在服务器上运行同一个项目时，在我打勾后，验证ReCaptcha时失败

日志：

我在服务器和本地机器上都使用Python 3.7。已安装的库列表：

bcrypt==3.1.7
certifi==2019.11.28
cffi==1.13.2
chardet==3.0.4

uwsgi.ini

[uwsgi]
module = antifraud_dashboard
callable = app

Dockerfile

FROM tiangolo/uwsgi-nginx-flask:python3.7

VOLUME /app

WORKDIR /app

COPY requirements.txt .

RUN echo "uwsgi_read_timeout 600s;" > /etc/nginx/conf.d/custom_timeout.conf

RUN pip install -r requirements.txt

更新：

UWSGI\u LAZY\u APPS=1

似乎没有效果，但在设置

PYTHONFAULTHANDLER=1

后，我得到了以下回溯：

将

PYTHONFAULTHANDLER

环境变量设置为某个值，例如

1

，您可能会得到一个回溯（）

uWSGI有一些不好的默认值，糟糕到我个人建议不要使用它，因为这样，但是如果必须：将

uWSGI\u LAZY\u APPS

env variable设置为

1

。默认情况下，uWSGI执行fork（）-without-exec（），这会导致崩溃和神秘的bug。在这种情况下，这可能不是问题，但仍然需要解决

---

更新了一个带有回溯的问题不确定uWSGI的env变量如何与uWSGI配置文件交互，因此值得尝试将其设置为配置选项。
