Thanks for this. I tried playing (briefly) with Neer’s package, but the reliance on XML sockets (and the associated security issues) made it a pain. Using the built-in URLLoader functionality in your example was much friendlier.

Thanks!

Hi borf. It sounds like you may be having the encoding issues that Vincent pointed out initially.

Sorry I didn’t get around to it sooner, but I’ve now updated to include the fixes he mentioned. You can grab the latest build from the updated link at the bottom of the post.

Let me know if you still get any errors.

Great addition to the community thanks! I am trying to post one file with this to an ASP page and I am getting the “Invalid procedure call or argument: ‘MidB’” error which is commonly due to the encoding type being wrong. I looked at the URLRequest in the debugger and everything appears ok. Ideas?

Appreciate the feedback Vincent, and I’m glad it was of some use to you. I’ll get those fixes up and tested soon.

hi,
first of all thanks for the code, it really helped me.
Second this code works great with a php backend but unfortunatly not with a java or a rails one (less tolerants).
there are two changes to make in URLRequestBuilder.as:
- the LF character for a network transaction is ‘\r\n’ and not ‘\n’
- in the iteration in encodeMultipartFile the FIRST time you call encodeMultipartVariable, the encoding function called (either encodeMultipartFile, encodeMultipartString) should NOT write LF at the beginning. Otherwise you have three LF between the http header and the body which result in a broken boundary.
With those fixes it works great.

Vincent
