无法使用内容类型 - JAX-RS

标签: java jax-rs resteasy

如果客户端连接到这样的Web服务(JAX-RS):

URL u = new URL(server);
URLConnection con = u.openConnection();
con.setDoOutput(true);
con.getOutputStream().write(stream.toByteArray()); // ByteArrayOutputStream 
con.connect();
InputStream inputStream = con.getInputStream();
byte [] urlBytes = new byte [inputStream.available()];
inputStream.read(urlBytes);
url = new String(urlBytes);

那么Web服务接口定义应该是什么?我有:

@POST 
@Path("/upload")
@Consumes("image/jpeg")
@Produces(MediaType.TEXT_PLAIN)
String uploadPicture();

但是,当客户端访问时,它会抛出:

此客户端的JAX-RS接口应该是什么?

更新

这里需要注意的一点是,客户端代码已经编译和签名,我无法改变它。

1 个答案:

答案 0 :(得分:5)

太糟糕了,你无法改变客户端...错误属于那里:

  • 未设置相应的Content-Type,因此连接默认为application/x-www-form-urlencoded

  • 然后它将图像数据作为简单的流发送(因此未正确编码)

可行解决方案的最短(艰难而不那么优雅)的道路可能是接受一切:

@POST 
@Path("/upload")
@Consumes("*/*")
@Produces(MediaType.TEXT_PLAIN)
String uploadPicture(InputStream image);
