ruby - 如何将 aws 中的 Gem 与 Ruby 结合使用？

Question

我想使用 gem httparty (作为示例)

我添加了一个 Gemfile

source 'https://rubygems.org'

gem 'httparty'

我的 lambda 代码有:

...
require 'httparty'

我用它来调用它

response = Net::HTTParty.get('example.com', '/index.html')

但是最初的require正在获取

{
  "errorMessage": "cannot load such file -- httparty",
  "errorType": "Init<LoadError>",
  "stackTrace": [
    "/var/lang/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require'",
    "/var/lang/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require'",
    "/var/task/lambda_function.rb:3:in `<top (required)>'",
    "/var/lang/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require'",
    "/var/lang/lib/ruby/site_ruby/2.5.0/rubygems/core_ext/kernel_require.rb:54:in `require'"
  ]
}

需要将非 aws gems 捆绑到本地供应商文件夹中，然后压缩要包含的那些依赖项，即

bundle install --path vendor/bundle  # <-- Note using path

zip -r function.zip lambda_function.rb vendor/ # <-- vendor/ for the dependencies

aws lambda update-function-code --function-name myFunction \
--zip-file fileb://function.zip --region 'us-east-2' # <= your region
