生成 WSDL 文件

Question

I want to implement a WSDL service. To generate its codes, I use from different tools. When I use SoapUI, the generated file's method is as below:

*******************************************************
<soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:tem="http://tempuri.org/">
    <soapenv:Header>
        <tem:AuthenticationHeader>
            <tem:TicketID>?</tem:TicketID>
        </tem:AuthenticationHeader>
    </soapenv:Header>
    <soapenv:Body>
        <tem:GetInfo>
            <tem:sNo>?</tem:sNo>
            <tem:source>?</tem:source>
        </tem:GetInfo>
    </soapenv:Body>
</soapenv:Envelope>

and when I use https://app.boomerangapi.com/ on Chrome, this method will be:

<x:Envelope
    xmlns:x="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:tem="http://tempuri.org/">
    <x:Header>
        <tem:AuthenticationHeader>
            <tem:TicketID>?</tem:TicketID>
        </tem:AuthenticationHeader>
    </x:Header>
    <x:Body>
        <tem:GetInfo>
            <tem:sNo>?</tem:sNo>
            <tem:source>?</tem:source>
        </tem:GetInfo>
    </x:Body>
</x:Envelope>

Why the generated methods are different in namespaces?!

What can be the problem in the source of this service?!

Answer 1

Those two SOAP bodies are exactly the same.

A namespace prefix in an element tag is just a symbolic shorthand for a namespace URI.

An XML document can define a namespace prefix using an attribute that starts with xmlns: :

xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

That attribute means “all names in this element and its descendants starting with soapenv: are actually names associated with the URI http://schemas.xmlsoap.org/soap/envelope/ .”

The following namespace definition is exactly the same thing; it just specifies a different prefix to use as shorthand for the same URI:

xmlns:x="http://schemas.xmlsoap.org/soap/envelope/"

So, the only difference is that the two XML documents is how they refer to the “http://schemas.xmlsoap.org/soap/envelope/” URI:

• The first document specifies that elements starting with soapenv: are associated with that URI.
• The second document specifies that elements starting with x: are associated with that URI.

The notation is different, but the meaning is the same. They literally have identical content.
