i am trying to use one of the method from the generated client as shown below
package io.swagger.client.api;
import com.squareup.okhttp.OkHttpClient;
import io.swagger.client.ApiClient;
import io.swagger.client.ApiException;
import io.swagger.client.Configuration;
import io.swagger.client.model.AppModel;
import io.swagger.client.model.NodeModel;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
public class testSample {
private final PlatformApi api = new PlatformApi();
public void getNodesTest() throws ApiException {
List<AppModel> response = api.getApps();
System.out.print("------------------------inside testsample------------------------");
System.out.print(response);
}
public static void main(String args[]){
testSample t1=new testSample();
System.out.print("------------------------inside main------------------------");
try{
ApiClient defaultApiClient = Configuration.getDefaultApiClient();
ApiClient apiClient = t1.api.getApiClient();
System.out.println(defaultApiClient);
System.out.println(apiClient);
t1.getNodesTest();
}
catch(Exception e){
System.out.println("inside exeption");
e.printStackTrace();
}
}
}
Please provide some suggestion how to use the generated java client from swagger in local

Answer 1

I hope these helps someone;
DefaultApi defaultApi = new DefaultApi();
ApiClient apiClient = new ApiClient();
apiClient.setBasePath("http://....");
apiClient.addDefaultHeader("Authorization", "bearer TOKEN");
OkHttpClient httpClient = apiClient.getHttpClient();
httpClient.setConnectTimeout(60, TimeUnit.SECONDS);
httpClient.setReadTimeout(60, TimeUnit.SECONDS);
httpClient.setWriteTimeout(60, TimeUnit.SECONDS);
defaultApi.setApiClient(apiClient);
SomeModel var1 = defaultApi.getNodesTest();
generator sample command;

The error below suggests that the Java API client couldn't connect to the API server:
io.swagger.client.ApiException: java.net.SocketTimeoutException: connect timed out
I would suggest you to verify the Swagger/OpenAPI spec to ensure it has a proper host setting, e.g.
host: petstore.swagger.io
e.g. https://github.com/swagger-api/swagger-codegen/blob/master/modules/swagger-codegen/src/test/resources/2_0/petstore.yaml#L12
Ref: Swagger 2.0 spec: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#swagger-object
