I'm posting a file to my web app using the following form:
<form accept-charset="UTF-8" action="@(url-for 'upload-contacts (organization-id org-obj))"
method="post" enctype="multipart/form-data" class="file-upload-form">
...
</form>
I use a simple function to create a hashtable of attributes:
(define (form-values req)
(for/hash ([ b (in-list (request-bindings/raw req)) ])
(cond [ (binding:form? b) (values
(bytes->string/utf-8 (binding-id b) #\space)
(bytes->string/utf-8 (binding:form-value b) #\space)) ]
[ (binding:file? b) (values
(bytes->string/utf-8 (binding-id b) #\space)
(binding:file-content b)) ])))
It appears that the entire file contents are in the binding by the time the request is available to me. This is fine for "small enough" files, but for larger files, it would be great to be able to stream the file contents. The solution may be to use something like nginx's upload module:
But before I go down that route, I thought I'd ask if the Racket web server provides a more direct way to accomplish this.
Thanks,
