Working with base64Binary value returned from web service

Posted by tgagnon on 25-Jul-2013 06:25

Hello Everyone,

I am trying to make use of the base64string data that was returned from a web service (RenderResponse).  The return response definition from it's wsdl is below:

<s:element name="RenderResponse">
<s:element name="Result" type="s:base64Binary" maxOccurs="1" minOccurs="0"/>
<s:element name="Extension" type="s:string" maxOccurs="1" minOccurs="0"/>
<s:element name="MimeType" type="s:string" maxOccurs="1" minOccurs="0"/>
<s:element name="Encoding" type="s:string" maxOccurs="1" minOccurs="0"/>
<s:element name="Warnings" type="tns:ArrayOfWarning" maxOccurs="1" minOccurs="0"/>   
<s:element name="StreamIds" type="tns:ArrayOfString" maxOccurs="1" minOccurs="0"/>

I am interested in getting the "Result" base64Binary value converted into a character string that I can display.

Currently I have the value returned from the web service call saved in a MEMPTR  variable.

Does anyone know how I convert the base64Binary data to a character string?

Thank you,

Hi Terry,

You can use COPY-LOB and BASE64-DECODE for this purpose.

COPY-LOB can be used to copy the value from a MEMPTR to a LONGCHAR.

Then you can use BASE64-DECODE to decode the string to whatever the original value was.

If you can get the web service return value to be stored in a LONGCHAR instead of in a MEMPTR, you can use BASE64-DECODE immediately.

I hope this answers your question.

Best regards,
