java - 如何在 Apache - CXF 客户端的上传文件后调用中发送 multipart/formData？

Question

您好，我正在我的项目中使用上传 api。我能够使用 jersy 客户端发送数据并获取响应。

我收到 200 作为 Response 。这是该代码。

    final Client client = ClientBuilder.newBuilder().register(MultiPartFeature.class).build();
    client.register(new LoggingFilter());
    FileDataBodyPart filePart = new FileDataBodyPart("file", new File("/Users/rasaminathan/Desktop/test.txt"));
    FormDataMultiPart formDataMultiPart = new FormDataMultiPart();
    FormDataMultiPart multipart = (FormDataMultiPart) formDataMultiPart.field("param1", "paramValue")
                                                .field("param2", "value")
                                                .bodyPart(filePart);   
    final WebTarget target = client.target("http://URL:8000/apiPath");
    final Response response = target.request().post(Entity.entity(multipart, multipart.getMediaType()));

这是我得到的日志。

    Jul 22, 2016 12:15:14 PM org.glassfish.jersey.filter.LoggingFilter log
    INFO: 1 * Sending client request on thread main
    1 > POST http://URL:8000/apiPath
    1 > Content-Type: multipart/form-data

    Jul 22, 2016 12:15:15 PM org.glassfish.jersey.filter.LoggingFilter log
    INFO: 1 * Client response received on thread main
    1 < 200

但是在我的项目中我们应该使用 CXF 。我尝试使用 CXF webclient 进行相同的操作。但我收到“401”未经授权的错误。这是代码。

    WebClient client = WebClient.create("http://URL:8000");
    String path = "apiPath"; 
    client.type(MediaType.MULTIPART_FORM_DATA)
            .path(path);

    ClientConfiguration config = WebClient.getConfig(client);
    config.getInInterceptors().add(new LoggingInInterceptor());
    config.getOutInterceptors().add(new LoggingOutInterceptor());

    List<Attachment> atts = new LinkedList<Attachment>();
    atts.add(new Attachment("file", "application/octet-stream", new ByteArrayInputStream("testContent".getBytes())));
    atts.add(new Attachment("param1","text/plain","paramValue"));
    atts.add(new Attachment("param2","text/plain","value"));
    MultipartBody body = new MultipartBody(atts);
    Response response= client.post(body);

这是我得到的日志。

我猜参数“Param1,Param2”值未正确发送。我猜这就是为什么我收到 401 错误的原因。我是否在 CXF Web 客户端中正确发送数据？如果不是请帮我更正代码

在所有附件中设置内容处置有助于解决该问题。我找到了解决方案 here.

正如我猜测的那样，Param1、param2 值未到达服务器。

        List<Attachment> atts = new LinkedList<Attachment>();
        ContentDisposition cd = new ContentDisposition("form-data; name=\"file\";filename=\"test.txt\"");
        atts.add(new Attachment("file", new ByteArrayInputStream("testContent".getBytes()),cd));
        ContentDisposition cd1 = new ContentDisposition("form-data; name=\"param1\";");
        atts.add(new Attachment("param1",new ByteArrayInputStream("paramValue".getBytes()),cd1));
        ContentDisposition cd2 = new ContentDisposition("form-data; name=\"param2\";");
        atts.add(new Attachment("param2",new ByteArrayInputStream("value".getBytes()),cd1));
        MultipartBody body = new MultipartBody(atts);
        Response response= client.post(body);

现在我收到成功响应
