如何将httpie与httpie-aws-authv4绑定到Python zipapp中？

Question

将httpie打包到Python "PYZ“(zipapp)中很简单，例如使用

$ pip install --upgrade zapp
$ zapp httpie.pyz httpie.__main__:main httpie
$ python ./httpie.pyz --version
1.0.3

现在，我尝试将httpie-aws-authv4作为一个插件包含到httpie中，用于AWS身份验证。遗憾的是，httpie并没有采用这个插件。

$ zapp httpie-aws4.pyz httpie.__main__:main httpie httpie-aws-authv4
$ python ./httpie-aws4.pyz       
usage: http [--json] [--form] [--pretty {all,colors,format,none}]
...   
            [--auth USER[:PASS]] [--auth-type {basic,digest}]

$ python ./httpie-aws4.pyz -A aws4 http://localhost:9200/
...
http: error: argument --auth-type/-A: invalid choice: u'aws4' (choose from 'basic', 'digest')

它应该显示为[--auth-type {basic,digest,aws4}]

有人知道怎么做吗？

根据记录，我通过在内置身份验证机制列表中注册扩展来解决插件加载问题。这使得插件可用并可操作，尽管是通过不同的机制。对于zipapp的使用，这是非常好的：

zapp httpie-aws4.pyz httpie.__main__:main httpie httpie-aws-authv4
mkdir -p httpie/plugins
unzip -q -c httpie-aws4.pyz httpie/plugins/__init__.py | gsed \
      -e '15i from httpie_aws_authv4 import AWSv4AuthPlugin # ADDED' \
      -e '19i AWSv4AuthPlugin, # ADDED' \
> httpie/plugins/__init__.py
zip httpie-aws4.pyz httpie/plugins/__init__.py

然后，根据需要显示aws4身份验证机制：

python ./httpie-aws4.pyz 2>&1 | grep auth-type
            [--auth USER[:PASS]] [--auth-type {aws4,basic,digest}]
