到lambda到rds的亚马逊API网关？
[英]Amazon API Gateway to lambda to rds?
问题描述
I am trying to have a mobile app access an amazon rds postgres instance. 
我想让移动应用程序访问亚马逊rds postgres实例。 Referencing https://stackoverflow.com/questions/36103629/is-it-posible-to-query-an-amazon-rds-instance-directly-from-api-gateway# = , Mark said "You should look into pointing API Gateway at a Lambda function that has the ability to connect to your RDS database and run queries." 参考https://stackoverflow.com/questions/36103629/is-it-posible-to-query-an-amazon-rds-instance-directly-from-api-gateway# = ，Mark说：“你应该研究指向API Lambda函数的网关，能够连接到RDS数据库并运行查询。“ So my question is could I implement this approach using this link: http://docs.aws.amazon.com/lambda/latest/dg/vpc-rds.html and then using api gateway to point at that lambda function? 所以我的问题是我可以使用以下链接实现此方法： http ： //docs.aws.amazon.com/lambda/latest/dg/vpc-rds.html然后使用api网关指向该lambda函数？ Then any mobile client with credentials from cognito would be able to call that api? 然后任何拥有来自cognito的凭据的移动客户端都可以调用该API吗？ Am I correct and is this the best way? 我是对的，这是最好的方法吗？ My worries is that since a VPC is involved, only a small number of people will be able to use the lambda function. 我担心的是，由于涉及VPC，只有少数人能够使用lambda函数。

Yes you could use the technique listed in your link (which is exactly what I was referring to in my other answer that you reference) and then expose that Lambda function via API Gateway. 是的，您可以使用链接中列出的技术（这正是我在您引用的其他答案中所指的那样），然后通过API网关公开该Lambda函数。 This is (one of ) the correct ways to accompolish this. 这是（其中一种）正确的方法。
My worries is that since a VPC is involved, only a small number of people will be able to use the lambda function.
I don't understand what you are saying here. 我不明白你在这说什么。 Why would use of a VPC restrict the number of people that could use the Lambda function? 为什么使用VPC会限制可以使用Lambda函数的人数？
