问iOS SDK如何调用Lambda函数？

EN

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] 

import AWSLambda

// ...

let request = AWSLambdaInvocationRequest()!
request.functionName = "name of your lambda"
request.invocationType = .requestResponse
let params: [String: Any] = [:]
request.payload = try! JSONSerialization.data(withJSONObject: params, options: [])

AWSLambda.default().invoke(request) { response, error in
    if let error = error {
        print(error)
    } else {
        print(response!.debugDescription)
    }
}
