Api Management

Call Old SOAP Service

Url: https://postnumbers.azurewebsites.net/Service.asmx Method: Post Headers:

SOAPAction: 	http://tempuri.org/GetCity
Content-Type: 	text/xml

Body:

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
	<Body>
		<GetCity xmlns="http://tempuri.org/">
    		<postnumber>8200</postnumber>
    	</GetCity>
	</Body>
</Envelope>

Create a blank API, with the Web Service Url
Add an operation (GetCity) GET -> /city/{postnumber}
Call the API operation https://aller.azure-api.net/postnumbers/city/{postnumber}

PostNumber = 5000 You will get a 401 Access Denied

Ocp-Apim-Subscription-Key: 529a799a71254c23aa66e54fecc68ec5;product=starter

500 Internal Error Trace will tell that http://xemmel.com/webservices/postnumber.asmx/city/5000 was called

Set the following policies on operation level

 <inbound>
        <base />
        <rewrite-uri template="?op=GetCity" copy-unmatched-params="false" />
        <set-method>POST</set-method>
        <set-header name="Content-Type" exists-action="override">
            <value>text/xml</value>
        </set-header>
        <set-body template="liquid">
			<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/">
				<Body>
					<GetCity xmlns="http://tempuri.org/">
						<pPostNumber>4000</pPostNumber>
					</GetCity>
				</Body>
			</Envelope>
		</set-body>
</inbound>

Read the Template Parameter instead of the hard-coded value

<pPostNumber>{{context.Request.MatchedParameters["postnumber"]}}</pPostNumber>

Change outbound policies*

 <outbound>
        <base />
        <xsl-transform>
			<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:source="http://tempuri.org/" exclude-result-prefixes="source">
				<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
				<xsl:template match="/">
					<Response>
						<xsl:value-of select="//source:GetCityResult" />
					</Response>
				</xsl:template>
			</xsl:stylesheet>
		</xsl-transform>
        <xml-to-json kind="javascript-friendly" apply="always" consider-accept-header="true" />
    </outbound>

Alter xslt to prettify JSON

<Response value="{//source:GetCityResult}" />
