Question

我正在尝试实现一个能够处理以下POST的REST端点：

-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowChunkNumber"

1
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowChunkSize"

1048576
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowCurrentChunkSize"

1474992
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowTotalSize"

1474992
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowIdentifier"

1474992-SAM_0391JPG
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowFilename"

SAM_0391.JPG
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowRelativePath"

SAM_0391.JPG
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="flowTotalChunks"

1
-----------------------------6739772541706953700536795627
Content-Disposition: form-data; name="file"; filename="SAM_0391.JPG"
Content-Type: application/octet-stream

因此，我尝试利用org.glassfish.jersey.media.multipart.FormDataMultiPart，如下所示：

  @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public void uploadImage(FormDataMultiPart multiPartData).

此时我正在寻找检索Content-Type：application / octet-stream的实际内容。有关如何处理此类内容的任何建议吗？

提前致谢

You could just use the @FormDataParam annotations

@Consumes(MediaType.MULTIPART_FORM_DATA)
public void uploadImage(@FormDataParam("file") InputStream file)

Or if you want to stick to using FormDataMultiPart, you could do something like

@Consumes(MediaType.MULTIPART_FORM_DATA)
public void uploadImage(FormDataMultiPart multiPartData) {
    FormDataBodyPart filePart = multiPartData.getField("file");
    if (filePart != null) {
        InputStream file = filePart.getEntityAs(InputStream.class);
    }
}

See:

Javadoc for FormDataMultiPart to get an idea of other things you can do programmatically.
