我正在为包含以下 lambda 权限语句的用户界面颁发 STS 令牌：

   {
     "Sid" : "AllowUserInvokeLambda",
     "Action": [
        "lambda:InvokeAsync",
        "lambda:InvokeFunction"
     ],
     "Effect": "Allow",
     "Resource": [
         "arn:aws:lambda:us-east-2:*:function:CreateThumbnail",
         "arn:aws:lambda:us-east-2:*:function:ImageScanner"
     ]
   },

当我尝试从浏览器中的 aws-sdk.js 调用该函数时，我收到一条错误消息：

"User: arn:aws:sts::123456789012:assumed-role/test_sts_role/user-12345 is not authorized to perform: lambda:InvokeFunction on resource: arn:aws:lambda:us-east-2:198765432109:function:ImageScanner"

我是否遗漏了该政策中的某些内容？

我发现了问题，您的保单缺少帐号。应该是这样

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowUserInvokeLambda",
      "Action": [
        "lambda:InvokeAsync",
        "lambda:InvokeFunction"
      ],
      "Effect": "Allow",
      "Resource": [
        "arn:aws:lambda:ap-southeast-2:012345678901:function:*"
      ]
    }
  ]
}

注意：您还应该将此策略分配给您担任的角色，而不是分配给正在担任的用户。你能确认那部分吗？
