How do I download a PDF file via HTTP?

Question

If I have been given a URL, how can I download that file and replace my current message with the result?

Answer 1

You can also use the qie.callRESTWebService() using the returnFullHttpResponse parameter as follows:

var urlTemplate = 'http://upload.wikimedia.org/wikipedia/en/a/a9/Example.jpg';

var parameterMap = qie.newParameterMap();

 

var responseRaw = qie.callRESTWebService("REST WS",

urlTemplate,

"GET",

null,

null,

parameterMap,

60000,

true);

 

var responseXML = qie.parseXMLString(responseRaw);

var base64Image = responseXML.getNode('/httpResponse/content');

var imageBytes = qie.base64DecodeToBytes(base64Image);

message = qie.createTextMessage(new java.lang.String(imageBytes, 'ISO-8859-1'));

 

Answer 2

You can download a PDF by using the following code in a custom mapping function:

// create HttpGet object

var request = new org.apache.http.client.methods.HttpGet(message.getNode('/').replaceAll(' ', '%20'));

   

try {

   // download

   var response = com.qvera.qie.utils.HttpClientUtils.getHttpClient('', '', 10000).execute(request);

   var entity = response.getEntity();

   if (entity !== null) {

      var stream = entity.getContent();

      try {

         var output = new java.io.ByteArrayOutputStream();

         var ch = stream.read();

         while (ch > -1) {

            output.write(ch);

            ch = stream.read();

         }

         message.setNode('/', output.toString('ISO-8859-1'));

      } finally {

         stream.close();

      }

   }

} finally {

   request.abort();

}
