我正在使用JAX-RS 2.0编写一个REST服务来模仿现有的HTTP接口。
这包括针对路径发布空请求,然后将内容POST到同一路径。
现在我的资源看起来像这样:
@Path("data")
public class MyResource {
@Inject
MyService service;
@POST
@Produces(MediaType.APPLICATION_OCTET_STREAM)
public byte[] init() {
return service.init();
}
@POST
@Produces(MediaType.APPLICATION_OCTET_STREAM)
@Consumes(MediaType.APPLICATION_OCTET_STREAM)
public byte[] work(byte[] data) {
return service.work(data);
}
}
不幸的是,当客户端尝试POST其init时,会发生以下错误:

有没有办法通过JAX-RS解决这个问题,还是我必须回到Servlet来处理这种特殊情况?
答案 0 :(得分:0)
我无法重现这个问题。考虑这个JAX-RS方法:
@POST
@Path("/bytes")
@Consumes(MediaType.APPLICATION_OCTET_STREAM)
public Response postOctetStream(byte[] bytes) {
return Response.ok(bytes.length).build();
}
考虑这个curl
电话:
$ curl -v -X POST -H "Content-Type: application/octet-stream" -d "" http://localhost:8080/WebApplication4/webresources/bytes
* About to connect() to localhost port 8080 (#0)
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8080 (#0)
> POST /WebApplication4/webresources/foo/bytes HTTP/1.1
> User-Agent: curl/7.29.0
> Host: localhost:8080
> Accept: */*
> Content-Type: application/octet-stream
> Content-Length: 0

< HTTP/1.1 200 OK
< X-Powered-By: Servlet/3.1 JSP/2.3 (GlassFish Server Open Source Edition 4.0 Java/Oracle Corporation/1.7)

< Content-Type: text/plain

如您所见,客户端设置Content-Length: 0
。服务器可以将此空体映射到零长度byte[]
。
