As the service I try to contact is reachable only by https I can not trace the
network traffic...
Does this answer your question Sergey?
Not really; the above has no Accept header listed, but I'm not sure it
is the reason for making the request to succeed.
Do you control the target server ? What does the server logs in both cases ?
Cheers, Sergey
Best regards

Betreff: Re: Upload file with CXF client proxy
Hi
What does HttpClient produces, is it actually a multipart request ?
Can you trace it and let me know what the differences are ?
Cheers, Sergey

Hi,
I'm trying to use CXF client proxies to connect to 3rd party REST Services
using typed interfaces. Among other things I need to upload a file with a POST
request to an URL. Using apache-httpclient the call to the service looks like
this and works:
CloseableHttpClient httpclient = HttpClients.createDefault();
try {
HttpPost httppost = new HttpPost(
"https://localhost/upload?name=test";);
File file = new File("d:/ws/file.txt");
FileEntity reqEntity = new FileEntity(file,
ContentType.create("application/vnd.qlik.sense.app"));
httppost.setEntity(reqEntity);
System.out.println("Executing request: "
+ httppost.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httppost);
try {
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
System.out.println(EntityUtils.toString(response.getEntity()));
EntityUtils.consume(response.getEntity());
} finally {
response.close();
}
} finally {
httpclient.close();
}
I tried to use the following interface to create a CXF client proxy to execute
the call via cxf:
public interface UploadService
{
String QUERY_PARAM_APPNAME = "name";
@POST
@Consumes("application/vnd.qlik.sense.app")
@Produces("application/json")
@Path("/upload")
UploadResponse upload(@QueryParam(QUERY_PARAM_APPNAME) final String
anAppName, final File anAppFile);
}
final UploadService proxy = JAXRSClientFactory.create(
https://localhost,
UploadService.class,
Collections.singletonList(new JacksonJsonProvider()));
proxy.upload("test", new File("d:/ws/file.txt"));
Instead of using File I already tried to use InputStream or byte[] but all the
requests result in a 400 response (BadRequest) from the server. As the server
is a 3rd party tool I have no more information about how the file is to be
uploaded other than that the file needs to be the request body.
I turned on the logging interceptors and the request looks fine:
Nov 05, 2014 3:42:04 PM org.apache.cxf.interceptor.LoggingOutInterceptor
INFO: Outbound Message
---------------------------
ID: 1
Address: https://localhost/upload?name=test
Http-Method: POST
Content-Type: application/vnd.qlik.sense.app

Accept=[application/json]}
Messages: Outbound Message (saved to tmp file):

(message truncated to 102400 bytes)
Payload: ....
But the response is
Nov 05, 2014 3:42:04 PM org.apache.cxf.interceptor.LoggingInInterceptor
INFO: Inbound Message
----------------------------
ID: 1
Response-Code: 400

API > REST Server/1.0.0.0 Microsoft-HTTPAPI/2.0], transfer-encoding=[chunked]}
Payload: File upload error
Thus my question is: How can I do the call that works using httpclient with cxf?
Best regards
