我在我的Android应用程序中使用retrofit2进行任何http / rest调用.现在我需要调用

Amazon AWS API Gateway生成的api.

AWS文档say我应该生成客户端代码抛出API网关控制台并使用类ApiClientFactory来构建请求：

ApiClientFactory factory = new ApiClientFactory();

// Use CognitoCachingCredentialsProvider to provide AWS credentials

// for the ApiClientFactory

AWSCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(

context, // activity context

"identityPoolId", // Cognito identity pool id

Regions.US_EAST_1 // region of Cognito identity pool

};

factory.credentialsProvider(credentialsProvider);

// Create an instance of your SDK (this should come from the generated code).

final MyApiClient client = factory.build(MyApiClient.class);

// Invoke a method (e.g., 'parentPath1Get(param1,body)') exposed by your SDK.

// Here the method's return type is OriginalModel.

OriginalModel output = client.parentPath1Get(param1,body);

// You also have access to your API's models.

OriginalModel myModel = new OriginalModel();

myModel.setStreetAddress(streetAddress);

myModel.setCity(city);

myModel.setState(state);

myModel.setStreetNumber(streetNumber);

myModel.setNested(nested);

myModel.setPoBox(poBox);

相反,我想像改造那样定义API：使用我编写的接口,将其连接到RxJava,OkHttp等……

我的问题是：如何使用Cognito Identity Provider签署改装请求？
