Amazon Web Services - API Gateway

Question

J'essaie d'intégrer AWS Api Gateway et AWS Lambda,
Je peux appeler la fonction Lambda et obtenir une réponse.
Mais lorsque j'utilise l'AWS API Gateway et appelez ma fonction Lambda à l'aide d'une méthode GET,
Je ne parviens pas à transmettre les paramètres à l'aide d'une chaîne de requête.

Voici mon Handler -

package example; 

import com.amazonaws.services.lambda.runtime.RequestHandler; 
import com.amazonaws.services.lambda.runtime.LambdaLogger; 
import com.amazonaws.services.lambda.runtime.Context; 

public class Hello implements RequestHandler<Request, Response>{ 
    public Response myHandler(Request request, Context context) { 

     LambdaLogger logger = context.getLogger(); 
     logger.log("received a Lambda request"); 
     logger.log("Name param contains: "+request.getName()+" Age param contains: "+request.getAge()); 
     String greetingString = String.format("Hello "+request.getName()+", you are "+request.getAge()+" years old"); 
     return new Response(greetingString); 
    } 

    public Response handleRequest(Request arg0, Context arg1) { 
     // TODO Auto-generated method stub 
     return null; 
    } 
} 

est ici la classe Request -

package example; 

public class Request { 
    String name; 
    String age; 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public String getAge() { 
     return age; 
    } 

    public void setAge(String age) { 
     this.age = age; 
    } 

} 

est ici la classe Response -

package example; 

public class Response { 
    String greetings; 

    public String getGreetings() { 
     return greetings; 
    } 

    public void setGreetings(String greetings) { 
     this.greetings = greetings; 
    } 

    public Response(String greetings) { 
     this.greetings = greetings; 
    } 

    public Response() { 
    } 

} 

Voici mon chaîne de test pour la fonction Lambda pour laquelle je reçois une réponse positive -

{ 
    "name": "Aniruddha", 
    "age": "25" 
} 

réponse succès à l'appel Lambda -

{ 
    "greetings": "Hello Aniruddha, you are 25 years old" 
} 

Maintenant, est ici le problème,
J'ai configuré une passerelle AWS API pour une méthode Get,
paramètres de erie sont -

?name=aniruddha&age=25 

Je reçois un corps de réponse -

{ 
    "greetings": "Hello null, you are null years old" 
} 

têtes de réponse -

{"Content-Type":"application/json"}

Vérifiez votre demande de passerelle API et la cartographie de réponse est correcte Ref: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html#input-variable-reference

En outre, ne pas oublier de déployer les changements api pour l'obtenir reflète

#set($allParams = $input.params()) 
{ 
    "params" : { 
    #foreach($type in $allParams.keySet()) 
    #set($params = $allParams.get($type)) 
    "$type" : { 
     #foreach($paramName in $params.keySet()) 
     "$paramName" : "$util.escapeJavaScript($params.get($paramName))" 
     #if($foreach.hasNext),#end 
     #end 
    } 
    #if($foreach.hasNext),#end 
    #end 
    } 
}
