Talking with a SOAP service using Savon gem in Ruby - ruby

Question

I'm trying to communicate with a soap service and I know that I should send a SOAP Envelope like this:
POST /webpay_test/SveaWebPay.asmx HTTP/1.1
Host: webservices.sveaekonomi.se
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "https://webservices.sveaekonomi.se/webpay/CreateOrder"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<CreateOrder xmlns="https://webservices.sveaekonomi.se/webpay">
<request>
<Order>
<ClientOrderNr>string</ClientOrderNr>
<CustomerReference>string</CustomerReference>
<OrderDate>dateTime</OrderDate>
<CountryCode>string</CountryCode>
<SecurityNumber>string</SecurityNumber>
<CustomerEmail>string</CustomerEmail>
<IsCompany>boolean</IsCompany>
<PreApprovedCustomerId>long</PreApprovedCustomerId>
<AddressSelector>string</AddressSelector>
</Order>
<InvoiceRows>
<ClientInvoiceRowInfo>
<ArticleNr>string</ArticleNr>
<Description>string</Description>
<PricePerUnit>double</PricePerUnit>
<NrOfUnits>double</NrOfUnits>
<Unit>string</Unit>
<VatPercent>int</VatPercent>
<DiscountPercent>int</DiscountPercent>
<ClientOrderRowNr>int</ClientOrderRowNr>
</ClientInvoiceRowInfo>
<ClientInvoiceRowInfo>
<ArticleNr>string</ArticleNr>
<Description>string</Description>
<PricePerUnit>double</PricePerUnit>
<NrOfUnits>double</NrOfUnits>
<Unit>string</Unit>
<VatPercent>int</VatPercent>
<DiscountPercent>int</DiscountPercent>
<ClientOrderRowNr>int</ClientOrderRowNr>
</ClientInvoiceRowInfo>
</InvoiceRows>
</request>
</CreateOrder>
</soap:Body>
</soap:Envelope>
here is the code I've wrote:
client = Savon::Client.new("https://webservices.sveaekonomi.se/webpay_test/SveaWebPay.asmx?wsdl")
res = client.create_order do |soap|
soap.namespace = "https://webservices.sveaekonomi.se/webpay_test/CreateOrder.asmx"
soap.body = { :auth => { :username => "username", :password => "pass", :client_number => "1111" },
:order => { :client_order_nr => "1000000", :customer_reference => "4212", :order_date => Date.today,
:country_code => "SE", :security_number => "1111111111", :is_company => false,
:customer_email => "me#gmail.com", :pre_approved_customer_id => 0 },
:invoice_rows => { :client_invoice_row_info => { :article_nr => "x100", :description => "something cool -- description",
:price_per_unit => 100, :nr_of_units => 3, :unit => "SEK", :vat_percent => 25,
:discount_percent => 0, :client_order_row_nr => "1"},
:client_invoice_row_info => { :article_nr => "x200", :description => "something cooler -- description",
:price_per_unit => 200, :nr_of_units => 2, :unit => "SEK", :vat_percent => 25,
:discount_percent => 0, :client_order_row_nr => "1" }
}
}
end
and it generates this, which is different from what I have as the template and that's why I'm getting an error:
<?xml version="1.0" encoding="UTF-8"?><env:Envelope xmlns:wsdl="https://webservices.sveaekonomi.se/webpay_test/CreateOrder.asmx" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<env:Body>
<wsdl:CreateOrder>
<invoiceRows>
<clientInvoiceRowInfo>
<clientOrderRowNr>1</clientOrderRowNr>
<pricePerUnit>200</pricePerUnit>
<nrOfUnits>2</nrOfUnits>
<unit>SEK</unit>
<vatPercent>25</vatPercent>
<articleNr>x200</articleNr>
<discountPercent>0</discountPercent>
<description>something cooler -- description</description>
</clientInvoiceRowInfo>
</invoiceRows>
<order>
<customerEmail>me#gmail.com</customerEmail>
<preApprovedCustomerId>0</preApprovedCustomerId>
<countryCode>SE</countryCode>
<clientOrderNr>1000000</clientOrderNr>
<securityNumber>11111111</securityNumber>
<customerReference>4212</customerReference>
<isCompany>false</isCompany>
<orderDate>2010-06-28</orderDate>
</order>
<auth>
<password>pass</password>
<clientNumber>1111</clientNumber>
<username>username</username>
</auth>
</wsdl:CreateOrder>
</env:Body>
</env:Envelope>
and here is the response:
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<CreateOrderResponse xmlns="https://webservices.sveaekonomi.se/webpay">
<CreateOrderResult>
<Accepted>false</Accepted>
<ErrorMessage>Failed to create or authorize order</ErrorMessage>
<SveaOrderNr>0</SveaOrderNr>
<RejectionCode>Error</RejectionCode>
<WillBuyInvoices xsi:nil="true" />
<AuthorizeId>0</AuthorizeId>
<AuthorizedAmount xsi:nil="true" />
<ExpirationDate xsi:nil="true" />
</CreateOrderResult>
</CreateOrderResponse>
</soap:Body>
</soap:Envelope>
could anyone tell me how can I solve this problem. and since I'm a newbie when it comes to SOAP would you also tell me if the order of the xml tags in the soap:Body tag is important or not?

Thanks to Steve, I found "Why is “wsdl” namespace interjected into action name when using savon for ruby soap communication?" where Nick and Steve were talking about a similar problem.
Like Nick, my problem was in the way Savon is cooking up a SOAP envelope. As recommended by Nick, I ended up monkey patching a couple of methods in the Savon SOAP class. It's in lib/savon/soap.rb
and I'm good to go now.
I'm a novice when it comes to SOAP and it's my first time writing a SOAP client, but honestly it SUCKS! I still remember my first time writing a client for a REST service and gosh it was fun.
REST ROCKS, SOAP SUCKS. that's all!

Answer 2

You are missing the <request> element.
Try replacing your soap.body with a single hash with a key of ::request and a value of the existing hash record that you have already.
EDIT 1:
Your namespace line within your code should be "https://webservices.sveaekonomi.se/webpay" not the full URL you have there currently.
