How to handle multipart POST using a URI template of form /prefix/{suffix} in OpenRasta?_问答_开发者

I'm trying to handle a POST of a multipart document in OpenRasta with a URI template declaration of /content/{contentId}, but it fails. The configuration is

ResourceSpace.Has.ResourcesOfType<Content>().AtUri("/content/{contentId}").HandledBy<ContentHandler>().RenderedByAspx("~/Views/ContentView.aspx").And.AsJsonDataContract();

The handler method is as follows:

public OperationResult Post(string contentId, IEnumerable<IMultipartHttpEntity> entities) {...}

I'm using the following curl command to test

./curl -v -F myPartName=@./hello.txt http://localhost:10247/content/id-1

The POST works fine if I remove "{contentId}" from the URI template and modify the handler accordingly.

Any ideas on how to resolve? Log file follows below. Thanks --Roland

From the log, you can see that the multipart codec is being used in key/value processsing mode. In that mode, the content of the multipart is being parsed instead of assigning the IEnumerable, and that certainly is an issue with that codec.

I've added a bug to fix this issue at https://github.com/openrasta/openrasta-core/issues/32

In the meantime, you can let the multipart codec deserialize the content as needed (which you can use by simply mapping a DTO or input parameters to the names of the form entities, OpenWrap will let you assign form data into standard properties and IFile or Stream for files).

Alternatively, depending on your needs, you can unregister the key/value mutlipart codec by overriding the dependency registrar and let the object-only registration work as normal.
