https://answers.axonivy.com/questions/3777/how-to-upload-a-file-to-a-rest-api<p>I am building a document management service with a RESTful API. </p> <pre><code>@Path("fileUpload") public class FileUploadService { @PUT @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadFile(@FormDataParam("file") InputStream fileStream, @FormDataParam("file") FormDataContentDisposition fileDetail) throws IOException { .... } } </code></pre> <p>It seems to work as expected if I use a third party client such as Postman. However, when using the REST activity of ivy I am unable to call this service. I always get errors stating the the header <code>X-Requested-By</code> is missing. Whats the issue? How can I send files using a REST Client Call activity?</p>enThu, 18 Apr 2019 04:19:34 -0400https://answers.axonivy.com/questions/3777/how-to-upload-a-file-to-a-rest-api/3779<p>Hi. The problem with <code>X-Requested-By</code> is that it shows up a lot even if it's not the problem. This issue was fixed in <a href="https://jira.axonivy.com/jira/browse/XIVY-3097">XIVY-3097</a>. So if you are sending a modyfing request like PUT or POST and you are sure that you set X-Requested-By Header then it's other issue. What your problem probably is, is that you need to set MediaType boundary like </p> <pre><code>MediaType contentType = MediaType.MULTIPART_FORM_DATA_TYPE; contentType = Boundary.addBoundary(contentType); </code></pre> <p>and use it in your entity as content-type. And it will not work if you use <em>MediaType.MULTIPART_FORM_DATA_TYPE</em> instead of <em>contentType</em></p> <p>Example:</p> <pre><code>MediaType contentType = MediaType.MULTIPART_FORM_DATA_TYPE; contentType = Boundary.addBoundary(contentType); Response apacheConnectorResponse = client .target(uri).request() .header("X-Requested-By", "ivy") .put(Entity.entity(createMultipart(realPdf), contentType)); </code></pre> <p>You are able to see the full example in <a href="https://developer.axonivy.com/permalink/lib/dev/connectivity-demos.iar">ConnectivityDemos (7.3 and newer)</a> &gt; rest &gt; FileUpload</p>ivy-jlaThu, 18 Apr 2019 04:19:34 -0400https://answers.axonivy.com/questions/3777/how-to-upload-a-file-to-a-rest-api/3779
