[SOLVED] Return more than one content-type from ColdFusion

Return more than one content-type from ColdFusion

I have a ColdFusion REST component. For one method (GET) I need to return a JSON response and a file to save.

I have this, but it's not doing what I hoped it would

// the getDocument function returns a PDF file
returnFile = getDocument(configuration, myNode);
getpagecontext().getresponse().setStatus( JavaCast( 'int', 200 ), "OK" );
cfcontent(type="application/json");
writeOutput(serializeJSON(outputPayload));
fName = "#payloadIn.documentName#.#lcase(payloadIn.documentMimeType)#";
cfheader(name="Content-Disposition", value="attachment;filename=#fName#");
writeOutput(returnFile);

I get the JSON and then the pdf dumps out after. I want to see the JSON and have the PDF be an attachment.

    "uniqueId": "18974-2025-000009",
    "documentName": "TestDocument-0140481423",
    "documentType": "Mitigating - Underwriting",

[and so on]

Solution

returnFile = getDocument(configuration, myNode);
fName = "#payloadIn.documentName#.#lcase(payloadIn.documentMimeType)#";
returnFile['fileData'] = ToBase64(FileReadBinary(fName));
getpagecontext().getresponse().setStatus( JavaCast( 'int', 200 ), "OK" );
cfcontent(type="application/json");
writeOutput(serializeJSON(outputPayload));

The response will have a key with the base64 representation if the file which client can read and write to a file.
