Acionador do Lambda antes da geração do token

Como oferecer compatibilidade com a personalização do token de acesso em um gatilho do Lambda de pré-geração do tokens

Gere uma UpdateUserPoolAPIsolicitação CreateUserPoolor. Você deve especificar um valor para todos os parâmetros que não deseja definir como padrão. Para obter mais informações, consulte Atualização da configuração do pool de usuários e do cliente do aplicativo.

Inclua o conteúdo a seguir no parâmetro LambdaVersion da solicitação. Um valor LambdaVersion de V2_0 faz com que o grupo de usuários adicione parâmetros para personalização do token de acesso. Para invocar uma versão de função específica, use uma ARN função Lambda com uma versão da função como valor de. LambdaArn

"PreTokenGenerationConfig": { 
   "LambdaArn": "arn:aws:lambda:us-west-2:123456789012:function:MyFunction",
   "LambdaVersion": "V2_0"
},

O token da versão 1 pode definir a associação ao grupo, IAM funções e novas reivindicações em tokens de ID.

O evento de solicitação da versão 2 adiciona campos que personalizam o token de acesso. Ele também adiciona suporte para tipos de claimsToOverride dados complexos no objeto de resposta. Sua função Lambda pode retornar os seguintes tipos de dados no valor de: claimsToOverride
