PDF Services API - File has been damaged

[Bobby_Solo]

After copying the code from Postman I can sucessfully gertate (in PHP using cURL) my tokens. I the POLL the returend link in javascript and sucessfully gernerate a respone. Here is part of the Polling code I use in javescript to save the response.

var xhr = new XMLHttpRequest();
xhr.open("GET", '<URL FROM HEADER>', true);
xhr.responseType = "blob";
xhr.setRequestHeader('Authorization', accTok);
xhr.setRequestHeader('x-api-key', '<KEY>');
xhr.onload = function(event) {
    if(this.status == 200) {
        // Create a new Blob object using the response data of the onload object
        var blob = new Blob([this.response], {type: 'application/octetstream'});
        //Create a link element, hide it, direct it towards the blob, and then 'click' it programatically
        let a = document.createElement("a");
        a.style = "display: none";
        document.body.appendChild(a);
        //Create a DOMString representing the blob and point the link element towards it
        let url = window.URL.createObjectURL(blob);
        a.href = url;
        a.download = 'myFile.pdf';
        //programatically click the link to trigger the download
        a.click();
        window.URL.revokeObjectURL(url);
        clearInterval(pollInterval);
    }else{
        //deal with your error state here
    }
};
xhr.send();

This generates and saves the PDF File, however this file can oly be opend in a browser. If it try loading it in Adobe Embed PDF Api, it shows up as damaged. When I try to upload myfile.pdf to this forum I get this:

Correct the highlighted errors and try again.

• The attachment's myfile.pdf content type (application/pdf) does not match its file extension and has been removed.

What am I missing?

Can you zip the file you got and try attaching it? Or email it to jedimaster@adobe.com.

So the issue is that the REST API is *not* returning just PDF binary, but a multipart response that *includes* the PDF. If you open the result in Notepad (or a text editor in general), you will see:

%PDF-1.7
binary stuff here...

In order to get the PDF, you have to handle the mutlpart response first.

Many thanks for the reply. As you can see from my code I'm not hadeling it properly. This is where the online documentation gets thin. I've no idea how to handle the application/octetstream. Is this encoded? How do i extract the pdf exactly in JavaScript? Any help or tips are greatly appreciated. 

[Bobby_Solo]

help! I did not want to mark this as a correct answer. How can i undo this?

[Raymond Camden · Accepted solution]

In this case, you would need to look up how to parse multipart responses - that's not specific to our API, but is generic. I know I struggled with this myself.

lucky for you i came across your thread and actually did this today...

<cfscript>
contentType = variables.fileres.Responseheader['Content-Type'];  
dataSource  = createObject("java", "javax.mail.util.ByteArrayDataSource").init(variables.fileres.fileContent.toByteArray(), javaCast( "string", contentType));
mimeParts   = createObject("java", "javax.mail.internet.MimeMultipart").init(dataSource);
for (i = 0; i < mimeParts.getCount(); i++) {
  bp = mimeParts.getBodyPart( javacast("int", i));
  if (!isNull(bp) && bp.isMimeType("application/octet-stream")) {
   outputFile = createObject("java", "java.io.File").init(variables.ocrFileHandle);
   bp.saveFile(outputFile);
  }
 }
</cfscript>

does anyone else think it's strange Adobe doesn't have a ColdFusion option in their insert code WYSIWYG???

[Raymond Camden]

If you are on ColdFusion, why not just use the Java SDK? 

[dwaynea8754223]

I don't have a great reason, but trying to restructure the architecture of an existing app, the use of dev environments and build tools and deployment strategies that are different from what I typically do, make writing the 9 or so lines of code above more efficient for me. Maybe if I started a new project I could take that path more easily. Probably just my lack of knowledge to make the sdk an option. Couldn't they just hand out the jar file?

[Raymond Camden]

There's an issue with our JAR and CF - but there's an easy workaround. I documented it here: https://medium.com/adobetech/adobe-coldfusion-and-document-services-living-in-harmony-46279ec09d21

[dwaynea8754223]

I'm looking at giving this a shot.... looks like he changed some of the class paths from what you have in your example. But thanks for the direction.

[dwaynea8754223]

Just thought I'd follow up on this... when his JAR is loaded in the CF class path, it creates conflict in some Java io functionality. <cfmailparam name="Content-Type" value="text/x-gm-impdata"> causes failure.

[Raymond Camden]

I'd suggest filing that as a bug report on his repo.
