推荐答案

您可以直接使用AWS iOS SDK调用lambda函数.这是一个代码段

You can invoke lambda functions directly using the AWS iOS SDK. Here is a code snippet

AWSLambda *lambda = [AWSLambda defaultLambda];
AWSLambdaInvocationRequest *invocationRequest = [AWSLambdaInvocationRequest new];
invocationRequest.functionName = @"functionname";
invocationRequest.invocationType = AWSLambdaInvocationTypeRequestResponse;
NSDictionary *parameters = ...

invocationRequest.payload = [NSJSONSerialization dataWithJSONObject:parameters
                                                            options:kNilOptions
                                                              error:nil];

[lambda invoke:invocationRequest]
