Can'；t获取流1:在Java 11 HTTP/2客户端中读取时达到EOF

我目前正在学习Java11中的HTTP/2客户端（

Java.net.HTTP

module）

我的目的是使用Java11HTTP/2客户端向本地服务器发送

POST

JSON

数据，但我发生了一些

IOException

，

eofeexception

例外情况

我的代码

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());

Path testPath=Path.get（System.getProperty（“user.dir”），“jsonSample.txt”）；
字节[]testb=Files.readAllBytes（testPath）；
System.out.println（新字符串（testb））；
HttpClient=HttpClient.newHttpClient（）；
HttpRequest请求=HttpRequest.newBuilder（）
.uri（uri.create（“http://localhost:8080" ) )
.header（“内容类型”、“应用程序/json”）
.header（“接受”、“应用程序/json”）

.POST（HttpRequest.bodypublisher.ofFile（testPath））
.build（）；
HttpResponse response=client.send（请求，HttpResponse.BodyHandlers.ofString（））；
System.out.println（response.statusCode（））；
System.out.println（response.body（））；

我做错了什么

我遇到了同样的问题，但我发现它是随机发生的，您可以再试一次，在您提出请求时确定它是否确实发生。

如果没有，您可以使用try-catch捕获此异常并再次执行请求。

这可能是因为您的服务器不支持HTTP/2。尝试向HttpRequest添加

version（HttpClient.version.HTTP\u 1\u 1）

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();

您的文件

“jsonSample.txt”

包括什么？该文件有{“firstName”：“John”，“lastName”：“Doe”，“age”：21}如果我使用

URI将其发布到示例web服务中，上述内容对我来说就很好了http://www.example.com/）

，本地服务实际应该做什么？它可能会对IO异常负责吗？哦。。谢谢你检查我的代码。我将检查我的本地服务器，然后评论。非常感谢。
