无法从邮递员读取文件

Question

I was trying postman with a Java clientava client. I was getting the following output

com.squareup.okhttp.internal.http.RealResponseBody@c9673cf

the original output is

Curl -I "http://ec2-52-34-14-38.us-west-2.compute.amazonaws.com:14000/webhdfs/v1/user/ec2-user/prediction_output/part-00000?user.name=ec2-user&op=OPEN"

1234.566788

here is my java code.

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import java.io.IOException;
@Path("/hello")
public class HelloWorldService {
@GET
@Produces("application/json")
public Response getMsg() throws IOException {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("http://ec2-52-34-14-38.us-west-2.compute.amazonaws.com:14000/webhdfs/v1/user/ec2-user/prediction_output/part-00000?user.name=ec2-user&op=OPEN")
 .build();
 com.squareup.okhttp.Response responses = null;
 responses = client.newCall(request).execute();
 System.out.println(responses);
 return Response.status(200).entity(responses.body().toString()).build();
}
} 

any help will be appreciated.

Answer 1

• Use response.body().string() not toString() .
• Use the above also in System.out.println .
• Your method getMsg() says @Produces("application/json") but your built response is text/plain .
