Upload File with Meta-Data (`multipart/form-data`) to ColdFusion 11 REST Service -

-

how access meta-data (form data) sent file upload (using enctype="multipart/form-data") in coldfusion 11 rest service?

mocking simple service:

component   restpath = "test"   rest     = true {   remove void function upload(     required numeric id       restargsource = "path",     required     document restargsource = "form",     required string  title    restargsource = "form"   )     httpmethod = "post"     restpath   = "{id}/"     produces   = "application/json"   {     if ( fileexists( document ) )       restsetresponse({         "status"  = 201,         "content" = {           "id"    = id,           "title" = title,           "size"  = getfileinfo( document ).size         }       });     else       restsetresponse({         "status"  = 400,         "content" = "nothing uploaded"       });   } }

and simple html file test it:

<!doctype html> <html> <body> <form method="post"       action="http://localhost/rest/testservice/test/1/"       enctype="multipart/form-data"> <input type="text" name="title"    value="file title" /><br /> <input type="file" name="document" /><br /> <button type="submit">submit</button> </form> </body> </html>

then service returns 500 http status code , json response:

{"message":"the document parameter upload function required not passed in."}

checking http request headers shows both fields passed in service not receiving them.

commenting out enctype attribute within html form (so uses default encoding of application/x-www-form-urlencoded) service returns 400 http status code , response nothing uploaded.

how can resolved?

to thoroughly confusing request data populates form variable but, though function arguments state restargsource="form", value not passed on rest service argument when enctype other application/x-www-form-urlencoded.

this confirmed in adobe's getting started restful web services in coldfusion article:

form parameters:

in many scenarios, must process data enter in form in rest service. can use data make new entry ( post ) or update existing record ( put ) in database. if use form fields, set restargsource form . extracts data present in request , makes available further processing. also, must set content-type header application/x-www-form-urlencoded when sending data form fields.

however, can solved changing arguments use restargsource="form" parameters explicitly scoped within form variable.

so, modifying service this:

component   restpath = "test"   rest     = true {   remove void function upload(     required numeric id       restargsource = "path"   )     httpmethod = "post"     restpath   = "{id}/"     produces   = "application/json"   {     param name="form.document" type="string";     param name="form.title"    type="string";      if ( fileexists( form.document ) )       restsetresponse({         "status"  = 201,         "content" = {           "id"    = id,           "title" = form.title,           "size"  = getfileinfo( form.document ).size         }       });     else       restsetresponse({         "status"  = 400,         "content" = "nothing uploaded"       });   } }
