How to post parameter with special symbol like "\/" or "|" in https://apigee.com GET api request? - apigee

Question

We are trying to use an external SOAP service in our mobile app. We are converting that SOAP service into a GET method REST api using https://apigee.com. But that REST api , is changing our parameter value (which contain some special character like / | and all), when hitting actual SOAP api. How can we stop this encoding/decoding part in Apigee? is their any other free service available there for same purpose ?

Answer 1

REST API GET Request. So you will be sending request parameters in the URL as query parameters. Use the below flow
Use Extract Variables policy to extract query parameter variables
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="true" enabled="true" name="getqueryparams">
<DisplayName>getqueryparams</DisplayName>
<QueryParam name="param1">
<Pattern ignoreCase="true">{param1}</Pattern>
</QueryParam>
<QueryParam name="param2">
<Pattern ignoreCase="true">{param2}</Pattern>
</QueryParam>
<QueryParam name="param3">
<Pattern ignoreCase="true">{param3}</Pattern>
</QueryParam>
<Source>request</Source>
<VariablePrefix>getqueryparams</VariablePrefix>
<IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
</ExtractVariables>
Use Service callout policy to create and send SOAP POST Request
<ServiceCallout async="false" continueOnError="false" enabled="true" name="Service-Callout-1">
<DisplayName>Custom label used in UI</DisplayName>
<Request clearPayload="true" variable="myRequest">
<IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
<Set>
<Headers>
<Header name="Content-Type">text/xml</Header>
<Header name="SOAPAction">http://www.webserviceX.NET/GetWeather</Header>
</Headers>
<Payload contentType="text/xml">
<?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>
<GetWeather xmlns="http://www.webserviceX.NET">
<CityName>{getqueryparams.param1}</CityName>
<CountryName>{getqueryparams.param2}</CountryName>
</GetWeather>
</soap:Body>
</soap:Envelope>
</Payload>
<Verb>POST</Verb>
</Set>
</Request>
<Response>response</Response>
<Timeout>60000</Timeout>
<HTTPTargetConnection>
<URL>http://www.webservicex.com/globalweather.asmx</URL>
</HTTPTargetConnection>
</ServiceCallout>
Use xml to json policy to convert the response xml to JSON in RESPONSE flow
Your service URL: http://superman-prod.apigee.net/service/getService?param1=abc/xyz&param2=one|two&param3=omgomgomg
