これは私のコードであり、「内部サーバーエラー」が発生するだけなので、デバッグ方法がわかりません。
外部ASPXにHTTPPOSTしようとしています:
def upload
uri = 'https://api.postalmethods.com/2009-02-26/PostalWS.asmx' #postalmethods URI
#https://api.postalmethods.com/2009-02-26/PostalWS.asmx?op=UploadFile
#http://www.postalmethods.com/method/2009-02-26/UploadFile
@postalcard = Postalcard.find(:last)
#Username=string&Password=string&MyFileName=string&FileBinaryData=string&FileBinaryData=string&Permissions=string&Description=string&Overwrite=string
filename = @postalcard.postalimage.original_filename
filebinarydata = File.open("#{@postalcard.postalimage.path}",'rb')
body = "Username=me&Password=sekret&MyFileName=#{filename}&FileBinaryData=#{filebinarydata}"
@response = RestClient.post(uri,
body, #body as string
{"Content-Type" => 'application/x-www-form-urlencoded',
"Content-Length" => @postalcard.postalimage.size} # end headers
) #close arguments to Restclient.post
end
