在Java 11 HTTP / 2客户端中读取时无法获得流1：达到EOF

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?

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();

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.
