Aws-lambda-dotnet: O AWS Lambda oferece suporte a invocações System.Drawing com libgdiplus?

Criado em 18 abr. 2018  ·  7Comentários  ·  Fonte: aws/aws-lambda-dotnet

Ei,

Implementei recentemente a geração de Captcha em meu AWS Lambda .NET Core 2 API. Eu poderia jurar que já estava funcionando, mas agora está simplesmente falhando. Eu examinei a implementação atual de System.Drawing do .NET Core; no entanto, pelo que estou lendo, as dependências explícitas do GDI + tornam essa biblioteca não compatível com várias plataformas. Após uma investigação mais aprofundada, existe um CompatCore.System.Drawing que foi originalmente desenvolvido pela equipe Mono. Supostamente, esta é uma versão de plataforma cruzada de System.Drawing que é capaz de usar a implementação baseada em Linux do GDI +; no entanto, a tentativa de usá-lo simplesmente gera o seguinte erro / rastreamento de pilha:

System.TypeInitializationException: The type initializer for 'System.Drawing.GDIPlus' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'gdiplus': The specified module or one of its dependencies could not be found.

De acordo com o seguinte tópico: https://github.com/CoreCompat/CoreCompat/issues/3

Eu deveria ter sido capaz de incluir a referência da DLL libgdiplus adicionando o pacote NuGet runtime.linux-x64.CoreCompat.System.Drawing; no entanto, isso foi em vão para mim. Tenho tentado várias combinações de referências de biblioteca na esperança de que esse seja um problema semelhante que muitas pessoas já viram com o System.Cryptography.x509Certificates; mas ainda não encontrei uma combinação que permita que isso funcione.

Alguém mais conseguiu colocar a funcionalidade System.Drawing em execução no AWS Lambda?

Sim, o Magick.NET foi atualizado alguns meses antes de começar a funcionar em várias plataformas. Tudo que eu precisava fazer era adicioná-lo ao projeto. Abaixo está uma função Lambda que escrevi para criar miniaturas de imagens com ela.

Eu ouvi falar sobre o uso de libgdiplus para System.Drawing no Linux, mas ainda não tentei. Para manipulação de imagens no Lambda, tenho usado a última versão do Magick.NET-Q16-AnyCPU . Não fiz nenhum desenho com ele, suponho que você precisaria para o Captcha, mas vejo que tem alguns recursos de desenho .

Meu problema parece ser que libgdiplus não é uma instalação padrão na instância do Lambda Linux. Supostamente, o runtime.linux-x64.CoreCompat.System.Drawing era um pacote NuGet que simplesmente executava scripts para instalar esta biblioteca via apt-get na inicialização do aplicativo; no entanto, depois de examinar o código deste projeto no link abaixo, não consegui entender exatamente como isso funciona ou por que pode estar falhando para mim.

https://github.com/CoreCompat/CoreCompat/tree/master/native/runtime.linux-x64.CoreCompat.System.Drawing

Vou continuar procurando por uma solução por enquanto; mas, aquele link do Magick.NET parece ser um método válido de gerar algumas imagens Captcha, então vou ter certeza de manter isso como um fallback. Eu pesquisei o uso do System.Drawing nativo, pois parece que foi desenvolvido para uma melhor compatibilidade entre plataformas, mas ainda parece que eles estão de alguma forma fazendo referência à biblioteca GDI + instalada,

Você viu este pacote Magick.NET usado com sucesso no Lambda?

Estou apenas entrando no Magick e acho que funcionará lindamente. Você não só tem acesso a uma API de manipulação de imagens relativamente diversa, como também parece ser uma plataforma cruzada bem suportada. Muito obrigado pela sugestão, um pouco mais de esforço de desenvolvimento e eu devo ser capaz de superar esse obstáculo sem problemas!

Ainda estou curioso para saber como algumas pessoas parecem ter conseguido colocar a implementação GDI + em funcionamento. Não vejo nenhuma maneira de obter a biblioteca libgdiplus apropriada instalada no Lambda antes da execução em tempo de execução.

Parece que a API ImageMagick Drawables pode não ser compatível com várias plataformas com AWS Lambda, pelo que estou vendo. Ao implementar a biblioteca e executar a função Draw (), estou gerando o seguinte erro:

Não importa o que eu faça, não consigo fazer nenhuma funcionalidade de desenho funcionar no Lambda. Tentei usar System.Drawing (Microsoft), CoreCompat.System.Drawing (Mono) e ImageMagick (terceiros), mas todos aparentemente sem sucesso. Cada biblioteca de geração de imagem parece ter algumas dependências de sistema importantes que estou tendo dificuldade em lidar com o AWS Lambda. Vou continuar a experimentar e relatar se tiver sucesso.

Existe alguma chance de que possamos personalizar nosso tempo de execução Lambda no futuro de forma semelhante a como podemos personalizar os contêineres do Docker? Tudo isso poderia ser resolvido com uma simples execução para instalar libgdiplus em minha instância Lambda.

Sou um idiota e nunca deveria ter gerado imagens Captcha em meu servidor AWS Lambda quando poderia simplesmente ter usado o Google ReCaptcha. Dessa forma, meu AWS Lambda lida apenas com o código de verificação e nunca precisa fazer referência a qualquer forma de funcionalidade de desenho.

Eu ainda gostaria de ver um método de implementação de alguma forma de funcionalidade de desenho no AWS Lambda no futuro; no entanto, vou colocar esse problema em banho-maria e atribuir isso a uma péssima decisão de design da minha parte por enquanto.

Talvez as camadas de implantação do Lambda possam remediar esse problema até que o suporte adequado esteja disponível no .Net Core em algum ponto.
