泽西岛图像上传客户端

Question

我正在尝试使用 Jersey webservice 上传图片，我正在使用 jersey 客户端上传图片。下面是球衣网络服务，它接受输入流并在服务器上上传图像。当我使用 jsp 多部分表单上传直接调用它时它工作正常但当我使用 jersey 客户端

上传图像时失败

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) throws ServiceException
{
    // upload code
}

下面是用于上传图片的 Jersey 客户端，客户端代码是从 php rest 客户端调用的另一个 Web 服务的一部分，如果我直接调用jersey 网络服务上传图像工作正常，但当我使用 jersey 客户端上传时它不工作。

ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
client.setChunkedEncodingSize(1024);
WebResource wr = client
        .resource("http://localhost:8080/rest/upload");

String contentDisposition = "attachment; filename=\""
        + fileDetail.getName() + "\"";
FormDataMultiPart form = new FormDataMultiPart();
ContentDisposition contentDisposition2 = new ContentDisposition(contentDisposition);
form.setContentDisposition(contentDisposition2);
FormDataBodyPart fdp = new FormDataBodyPart("file",
        uploadedInputStream, MediaType.MULTIPART_FORM_DATA_TYPE);
form.bodyPart(fdp);
ClientResponse response = wr.type(MediaType.MULTIPART_FORM_DATA).post(
        ClientResponse.class, form)

请帮助我确定我在这里遗漏了什么。谢谢

这是使用球衣客户端和网络服务上传图片的完整示例客户端代码

public class Test {

    private static URI getBaseURI() {
        return UriBuilder.fromUri("http://localhost:8080/restfullwebservice/resources/generic").build("");
    }

    public static void main(String[] args) throws FileNotFoundException {
        final ClientConfig config = new DefaultClientConfig();
        final Client client = Client.create(config);

        final WebResource resource = client.resource(getBaseURI()).path("upload");

        final File fileToUpload = new File("C:/Users/Public/Pictures/Desert.jpg");

        final FormDataMultiPart multiPart = new FormDataMultiPart();
        if (fileToUpload != null) {
            multiPart.bodyPart(new FileDataBodyPart("file", fileToUpload,
                    MediaType.APPLICATION_OCTET_STREAM_TYPE));
        }

        final ClientResponse clientResp = resource.type(
                MediaType.MULTIPART_FORM_DATA_TYPE).post(ClientResponse.class,
                multiPart);
        System.out.println("Response: " + clientResp.getClientResponseStatus());

        client.destroy();
    }
}

网络服务服务器代码

@POST
@Path("upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public void uploadFile(@FormDataParam("file") InputStream uploadedInputStream, @FormDataParam("file") FormDataContentDisposition fileDetail) throws ServiceChannelException {
    OutputStream os = null;
    try {
        File fileToUpload = new File("C:/Users/Public/Pictures/Desert1.jpg");
        os = new FileOutputStream(fileToUpload);
        byte[] b = new byte[2048];
        int length;
        while ((length = uploadedInputStream.read(b)) != -1) {
            os.write(b, 0, length);
        }
    } catch (IOException ex) {
        Logger.getLogger(GenericResource.class.getName()).log(Level.SEVERE, null, ex);
    } finally {
        try {
            os.close();
        } catch (IOException ex) {
            Logger.getLogger(GenericResource.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}
