Java Swagger generated rest client Problem authorizing requests via the generated client.

Hello ,

I am getting error in java client as below while using Basic Authentication in Swagger 2.0 version.
while generating client (java client) , we used swagger-codegen-cli-2.1.2.jar version.

io.swagger.client.ApiException: Authentication Required
at io.swagger.client.ApiClient.invokeAPI(ApiClient.java:445)
at io.swagger.client.api.CustomersApi.customersGet(CustomersApi.java:97)

from java level i can generate token by username:password.

token is matching between swagger UI tool and Java client.

below is the sample code
String auth = key + ":" + secret;
byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
String authHeader = "Basic " + new String(encodedAuth);
System.out.println("the basic auth header value is "+authHeader);

i am not sure how to pass this token in request header.
kindly help me , how to attach generated token in request header by using Generated Java Client API Classes?

Start by reading the generated client flow in ApiClient.java around invokeAPI and the call from CustomersApi.java. Reproduce the Basic Authentication request with swagger-codegen-cli-2.1.2.jar and compare it with the working Swagger UI request. Done means the generated Java client sends the expected authorization header and the request no longer returns Authentication Required.
