Docker 中的 SSL UNSUPPORTED_PROTOCOL Python 3

Question

我尝试通过 https 从网站获取数据并收到 SSL 证书错误，但是当我在我的 Mac 上运行时 - 一切正常。

我也尝试使用 curl 并得到同样的错误，

curl: (35) error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol

我在 Docker 容器 My Dockerfile 中运行解析器：

FROM python:3.7

WORKDIR /parser
COPY ./requirements.txt .

RUN python -m pip install --upgrade pip

RUN pip install -r requirements.txt

COPY . /parser

我收到以下错误：

Answer 1

我在 Dockerfile 中使用以下命令解决了我的问题：

RUN    apt-get update \
    && apt-get install openssl \
    && apt-get install ca-certificates

而且还需要添加Python包pyopenssl中requirements.txt
