How to unzip unzip multipar/form-data in Erlang?

Question

I have a Erlang application and I need to read a zip file pass in a POST request. At the moment I'm use this solution but return an error.

FileUnziped = zip:unzip(Payload),

I pass in a body of a post request like this image

And the error is:

{error,bad_eocd}

Is there any solution for this problem?

Looks like the Payload/*.zip data/file what you try unzip is damaged or improperly packed, see logic in zip.erl. Here is example:

1> {ok, Data} = file:read_file("tester.txt.zip").
{ok,<<80,75,3,4,10,0,0,0,0,0,133,165,69,81,0,0,0,0,0,0,0,0,0,0,0,0,10,...>>}
2> zip:unzip(Data).                                   
{ok,["tester.txt"]}
3> zip:unzip(<<Data/binary, "break archive">>).    
{error,bad_eocd}

Make sure that in Payload provided correct data.
