detergentex's Issues

Detergent is now released on Hex

https://hex.pm/packages/detergent

Pass an empty parameter

How to pass an empty parameter. For example, I have method with 5 parameters and first parameter must be empty. I try pass nil, empty string("", " "), but without success, throw {:error, 'nil value provided for non-nillable element}
Although the first parameter of method is <nillable="true"/>

Problem with erlsom parsing

I get the following error:

iex(1)> Detergentex.call("http://webapi.allegro.pl/service.php?wsdl", "doQuerySysStatus", [])
** (throw) {:error, 'Struct doesn\'t match model: recordtype not expected: p:doQuerySysStatus'}
    (erlsom) src/erlsom_write.erl:357: :erlsom_write.findAlternative/4
    (erlsom) src/erlsom_write.erl:258: :erlsom_write.processSubType/5
    (erlsom) src/erlsom_write.erl:241: :erlsom_write.processElementValues/7
    (erlsom) src/erlsom_write.erl:132: :erlsom_write.struct2xml/6
    (erlsom) src/erlsom_write.erl:323: :erlsom_write.processAlternativeValue/8
    (erlsom) src/erlsom_write.erl:241: :erlsom_write.processElementValues/7
    (erlsom) src/erlsom_write.erl:116: :erlsom_write.struct2xml/6
    (erlsom) src/erlsom_write.erl:323: :erlsom_write.processAlternativeValue/8

even if I have this operation listed:

iex(2)> Detergentex.init_model("http://webapi.allegro.pl/service.php?wsdl")
{:wsdl,
 [
  {:operation, 'serviceService', 'servicePort', 'doQuerySysStatus',
   'serviceBinding', 'https://webapi.allegro.pl/service.php',
   '#doQuerySysStatus'},
  ...
 {:model,
  [{:type, :_document, :sequence,
    [{:el,
      [
       {:alt, :"p:doQuerySysStatusResponse", :"p:doQuerySysStatusResponse", [],
        1, 1, true, :undefined},
        ...
      ]
  }]}]}
 ]
 ...
}

What may be the reason?

Add header to SOAP Request

Does anyone have an example about how to add header to request? I'm searching and trying for whole night without any positive result.

Thank you so much

problem to search project in hex

hexpm/hexpm#128

Error {:error, 'Struct doesn\'t match model: recordtype not expected: p:login'}

I am trying connecting to Magento soap API but I always get that error.

Please help me resolve it.

I use this soap api /api/v2_soap?wsdl=1

Thank you so much

https support

SOAP requests to https urls fails with {:error, :enoent}

I traced it back to src/detergent.erl in deps, which doesn't have pattern matching for URLs starting with https. It falls back to reading from a local file with the name of the URL, which doesn't exist. The code I'm seeing is

get_url_file("http://"++_ = URL) ->
    case httpc:request(URL) of
    {ok,{{_HTTP,200,_OK}, _Headers, Body}} ->
        {ok, Body};
    {ok,{{_HTTP,RC,Emsg}, _Headers, _Body}} ->
        error_logger:error_msg("~p: http-request got: ~p~n", [?MODULE, {RC, Emsg}]),
        {error, "failed to retrieve: "++URL};
    {error, Reason} ->
        error_logger:error_msg("~p: http-request failed: ~p~n", [?MODULE, Reason]),
        {error, "failed to retrieve: "++URL}
    end;
get_url_file("file://"++Fname) ->
    {ok, Bin} = file:read_file(Fname),
    {ok, binary_to_list(Bin)};
%% added this, since this is what is used in many WSDLs (i.e.: just a filename).
get_url_file(Fname) ->
    {ok, Bin} = file:read_file(Fname),
    {ok, binary_to_list(Bin)}.

However detergent at https://github.com/devinus/detergent/blob/master/src/detergent.erl has the same version of the dependency in detergentex (0.3.0) and does support https (https://github.com/devinus/detergent/blob/master/src/detergent.erl#L395).

get_url_file(URL) ->
    case xmerl_uri:parse(URL) of
        {http, _, _, _, _} -> get_remote_file(URL);
        {https, _, _, _, _} -> get_remote_file(URL);
        _Other -> get_local_file(URL)
end.

That was added in 2013 with devinus/detergent@5354f1c#diff-c46a9580e05c152c0b037750f88eb760

It happens that detergentex is downloading an older detergent or some different fork. However https://hex.pm/packages/detergent links to https://github.com/devinus/detergent

I wonder if there is some dependency mismatch and if mix.exs could be updated to depend from the version at https://github.com/devinus/detergent

Thanks

Access to authenticated web services.

Hi Ricardo,
Does detergentex support authenticated services? I need to contact a service using elixir that requires username/password.
Thank you.

No idea why this happens :/

Any info on what i can do to get closer is also welcome, but my erlang is very limited

{:ok, :undefined, :undefined}

When i launch the example request or this one : http://www.webservicex.net/New/Home/ServiceDetail/42

I get this answer from the service : {:ok, :undefined, :indefined}
Am I missing something?

here is my code:

Detergentex.init_model("http://www.webservicex.net/uszip.asmx?WSDL")
Detergentex.call("http://www.webservicex.net/uszip.asmx?WSDL", "GetInfoByZIP", ["35006"])
