在GAE中的python SAML [英] python SAML in GAE

问题描述

是否有一个库可用于在App Engine中使用python进行SAML身份验证？

我看了 pysaml2 ，它确实说它是纯粹的python实现。但是，它使用subprocess.Popen，它不能在App Engine中使用，并且在那个时候会失败。

解决方案

您可以使用python -saml on GAE如果您使用flex环境并使用由标准python27 构建的自定义运行时运行时由Google提供。我刚刚获得了onelogin的 python-saml flask-demo ，成功地处理了这个问题使用以下设置：

Dockerfile：

  FROM gcr。 io / google_appengine / python 
 LABEL python_version = python 
运行virtualenv / env -p python 
 
＃为运行时尚未包含的onelogin依赖项安装系统软件包
 RUN apt - 更新&& apt-get --yes --quiet install python2.7-dev libxmlsec1-dev 
 
＃设置virtualenv环境变量。这相当于运行
＃source / env / bin / activate 
 ENV VIRTUAL_ENV / env 
 ENV PATH / env / bin：$ PATH 
 ADD requirements.txt / app / 
 RUN pip install -r requirements.txt 
 ADD。 / app / 
 CMD python index.py 
  

app.yaml

 运行时：自定义
 env：flex 
入口点：python index.py 
 
 api_version：1 
 threadsafe：true 
  

requirements.txt

  flask == 0.10.1 
 python-saml 
  

然后简单地执行 gcloud app deploy app.yaml --version v1

Is there a library I can use to do a SAML authentication in App Engine using python?

I've looked at pysaml2 which does say it's pure python implementation. However, it's using subprocess.Popen which cannot be used within App Engine and will fail at that point.

解决方案

You can use python-saml on GAE if you use the flex environment with a custom runtime built off of the standard python27 runtime provided by google. I just got onelogin's python-saml flask-demo successfully working with this approach using the following settings:

Dockerfile:

FROM gcr.io/google_appengine/python
LABEL python_version=python
RUN virtualenv /env -p python

# Install system packages for onelogin dependencies not already included in runtime
RUN apt-get update && apt-get --yes --quiet install python2.7-dev libxmlsec1-dev

# Set virtualenv environment variables. This is equivalent to running
# source /env/bin/activate
ENV VIRTUAL_ENV /env
ENV PATH /env/bin:$PATH
ADD requirements.txt /app/
RUN pip install -r requirements.txt
ADD . /app/
CMD python index.py

app.yaml

runtime: custom
env: flex
entrypoint: python index.py

api_version: 1
threadsafe: true

requirements.txt

flask==0.10.1
python-saml

then simply do gcloud app deploy app.yaml --version v1
