Answer 1

I solved by defined only one schema tag, example:

From:

<types>
    <xsd:schema targetNamespace="http://www.russianpost.org/custom-duty-info/data">
        <xsd:import namespace="http://www.russianpost.org/custom-duty-info/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=1"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://www.russianpost.org/RTM/DataExchangeESPP/Data">
        <xsd:import namespace="http://www.russianpost.org/RTM/DataExchangeESPP/Data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=2"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://schemas.xmlsoap.org/soap/envelope/">
        <xsd:import namespace="http://schemas.xmlsoap.org/soap/envelope/"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=3"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://russianpost.org/sms-info/data">
        <xsd:import namespace="http://russianpost.org/sms-info/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=4"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://russianpost.org/operationhistory/data">
        <xsd:import namespace="http://russianpost.org/operationhistory/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=5"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://russianpost.org/operationhistory">
        <xsd:import namespace="http://russianpost.org/operationhistory"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=6"/>
    </xsd:schema>
</types>

To:

<types>
    <xsd:schema targetNamespace="http://www.russianpost.org/custom-duty-info/data">
        <xsd:import namespace="http://www.russianpost.org/custom-duty-info/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=1"/>
        <xsd:import namespace="http://www.russianpost.org/RTM/DataExchangeESPP/Data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=2"/>
        <xsd:import namespace="http://schemas.xmlsoap.org/soap/envelope/"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=3"/>
        <xsd:import namespace="http://russianpost.org/sms-info/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=4"/>
        <xsd:import namespace="http://russianpost.org/operationhistory/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=5"/>
        <xsd:import namespace="http://russianpost.org/operationhistory"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=6"/>
    </xsd:schema>
</types>

I got the same problem but haven't solved it.

Version: "soap": "^0.19.0"

    Target-Namespace "undefined" already in use by another Schema!
Target-Namespace "undefined" already in use by another Schema!
/Users/andreas/scm/todoListApi/node_modules/soap/lib/wsdl.js:481
    this.element = schema.elements[nsName.name];
                         ^

TypeError: Cannot read property 'elements' of undefinedTarget-Namespace "undefined" already in use by another Schema!

Update: the WSDL does not contain targetNamespace. How to work around that? Can I use the WSDL Options somehow?

Answer 3

While the above top solution does work, it's a poor solution since it defeats the whole purpose of WSDLs. SoapUI works fine with the service I'm using and this tool should be able to as well.

I ended up solving this by updating the node-soap code in node_modules\soap\lib\wsdl\elements.js by adding the following lines after line 826: var targetNamespace = child.$targetNamespace;:

if (!targetNamespace && child.includes && child.includes.length === 1) {
    targetNamespace = child.includes[0].namespace;
}

This works if you have a schema element where the only child is an import element (see example below). May try to get a PR approved if the maintainer is up for it.

Example:

<types>
  <xsd:schema>
    <xsd:import namespace="http://schema.core.datamodel.fs.documentum.emc.com/" schemaLocation="ObjectService_schema1.xsd"/>
  </xsd:schema>
  <xsd:schema>
    <xsd:import namespace="http://rt.fs.documentum.emc.com/" schemaLocation="ObjectService_schema2.xsd"/>
  </xsd:schema>
</types>

See git repo for original TS code: https://github.com/.../node-soap/.../elements.ts#L826

Answer 4

Solved. Workaround of issue. First instead of their .wsdl file I use modified original wsdl file and store it locally.

workaround of xml file Fixed it by adding into schema targetnNamespace parameter.

<definitions ... xmlns:myns="http://russianpost.org/operationhistory">
<types>
    <xsd:schema targetNamespace="http://www.russianpost.org/custom-duty-info/data">
        <xsd:import namespace="http://www.russianpost.org/custom-duty-info/data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=1"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://www.russianpost.org/RTM/DataExchangeESPP/Data">
        <xsd:import namespace="http://www.russianpost.org/RTM/DataExchangeESPP/Data"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=2"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://schemas.xmlsoap.org/soap/envelope/">
        <xsd:import namespace="http://schemas.xmlsoap.org/soap/envelope/"
                    schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=3"/>
    </xsd:schema>
    <xsd:schema targetNamespace="http://russianpost.org/sms-info/data">

Original wsdl code part

    <types>
    <xsd:schema>
        <xsd:import namespace="http://www.russianpost.org/custom-duty-info/data" schemaLocation="https://tracking.russianpost.ru/rtm34?xsd=1"/>

    </xsd:schema>
</types>
<message name="getOperationHistory">
    <part name="parameters" element="tns:getOperationHistory"/>
</message>

now to use our wsdl file:

var SoapClient = require('soap');
var options = {
    'trace': 1,
    "overrideRootElement": {
        "namespace": "myns",
        "xmlnsAttributes": [{
            "name": "xmlns:ns2",
            "value": "http://russianpost.org/operationhistory"
        }]
    },
    forceSoap12Headers: true,
    connection: 'keep-alive',
    'soap_version': 2
};
SoapClient.createClient('./local_wsdl.xml', options, function (err, client) {
    client.getOperationHistory(
        {
        'ns1:OperationHistoryRequest': {
            'ns1:Barcode': trackValue,
            'ns1:MessageType': 0,
            'ns1:Language': 'RUS',
        },
        'ns1:AuthorizationHeader': {
            'ns1:login': login,
            'ns1:password': password,
        },
    },
    (err, result) => {
        if (err) {
            console.log(err);

            return;
        }

        console.log(result.OperationHistoryData);
    }
    );
}
