Can't get Stream 1: EOF reached while reading in Java 11 HTTP/2 Client

Question

I'm currently learning HTTP/2 Client in Java 11(java.net.http module)

My purpose is send a POST JSON data to local server using Java 11 HTTP/2 Client, but I occurred some IOException, EOFException.

Exceptions

Exception in thread "main" java.io.IOException: Can't get stream 1: java.io.EOFException: EOF reached while reading

My Code

Path testPath = Paths.get( System.getProperty( "user.dir" ), "jsonSample.txt" );
byte[] testb = Files.readAllBytes( testPath );
System.out.println( new String( testb ) );

HttpClient client = HttpClient.newHttpClient();

HttpRequest request = HttpRequest.newBuilder()
                .uri( URI.create( "http://localhost:8080" ) )
                .header("Content-Type", "application/json")
                .header( "Accept", "application/json" )
//              .header( "User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36" )
                .POST( HttpRequest.BodyPublishers.ofFile( testPath ) )
                .build();

HttpResponse<?> response = client.send( request, HttpResponse.BodyHandlers.ofString());

System.out.println(response.statusCode());
System.out.println(response.body());

What am I doing wrong?

what does your file "jsonSample.txt"includes? – Intercalate

that file has { "firstName": "John", "lastName": "Doe", "age": 21 } – Ceasefire

The above just works fine for me, if I POST it to a sample web service using URI.create("http://www.example.com/"), what is the local service actually supposed to do and could it be responsible for the IO exception? – Intercalate

Oh.. thanks for checking my code. I will check my local erver, and then comment on. Thank you! – Ceasefire

Answer 1

This could be because your server does not support HTTP/2. Try adding version(HttpClient.Version.HTTP_1_1) to the HttpRequest

HttpRequest request = HttpRequest.newBuilder()
            .uri( URI.create( "http://localhost:8080" ) )
            .header("Content-Type", "application/json")
            .header( "Accept", "application/json" )
            .version(HttpClient.Version.HTTP_1_1)
            .POST( HttpRequest.BodyPublishers.ofFile( testPath ) )
            .build();

Answer 2

I have met the same question, but I find it is occur in random, you can try again and find whether it is occur certainly when you do your request. If not, you can use try catch to catch this exception and do your request again.
