亚马逊网络服务 - API网关

Question

我正在尝试整合AWS Api网关和AWS Lambda，
我可以调用Lambda函数并获得响应。
但是，当我使用AWS API网关并使用GET方法调用我的Lambda函数时，我无法使用查询字符串传递参数
。

这里是我的处理程序 -

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; 
    } 
} 

这里的Request类 -

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; 
    } 

} 

这里的Response类 -

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() { 
    } 

} 

这是我对这个lambda函数，我得到一个成功的响应测试字符串 -

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

成功响应LAMBDA呼叫 -

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

现在，这里的问题，
我为获取方法配置了AWS API网关，
预期的曲线ERY参数 -

?name=aniruddha&age=25 

我得到回应体 -

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

响应头 -

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

检查您的API网关的请求和响应映射正确 编号：http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html#input-variable-reference

另外，不要忘了部署API的变化来获得它反映

#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 
    } 
}
