service responses binary data

Hi,

 

I am trying to create a mock service that reads some binary data from a file. The mock service needs to send back a http response using just the binary data as the content. Since I do not know the encoding of the binary data, I cannot encode the binary to, e.g., hex string. I have tried to search for possible solutions, but I couldn't find what I am looking for. Can anyone please help me with this issue? Thank you very much in advance.

 

Regards,

Peter

    Hi,

     

    Here is one example below of how to achieve this, I think you just need the last line to convert to hex string.

     

    import java.io.FileInputStream
    import java.io.File

    File f = new File("/.rnd")
    FileInputStream fis = new FileInputStream(f)
    byte[] b = new byte[f.length()]
    fis.read(b)
    log.info javax.xml.bind.DatatypeConverter.printHexBinary(b) //returns a hex string

     

     

    Regards,

    Marcus

      I've got same kind of problem.

      I'm using Ready! API and 'the ServiceV for a rest service to mock a download of a file with an url.

      The filename is the parameter of the REST api and the directory is set as a custom project property.

       

       

      def fileDir = context.mockService.getProperty("fileDir").value
def filename = requestContext.getProperty("filename")
def file = new File(fileDir + '\\' + filename)
mockResponse.contentType = 'application/octect-stream'
def headers = mockResponse.getResponseHeaders()
def headerKey = 'Content-Disposition'
def headerValue = 'attachment; filename="' + filename + '"'
headers[headerKey] = [headerValue]
mockResponse.responseHeaders = headers
if (file.exists() && file.isFile()){
  byte[] fileBytes = file.getBytes()
  if (fileBytes.length > 0){
    try{
      //mockResponse.responseContent="bytes:" + fileBytes.length
      
      com.eviware.soapui.impl.rest.mock.RestMockResult mockResult = mockResponse.getMockResult()
      mockResult.setRawResponseData(fileBytes)

      //mockResponse.responseContent=javax.xml.bind.DatatypeConverter.printHexBinary(fileBytes)
    }
    catch(Exception e){
      mockResponse.responseContent = "Exception:" + e.getMessage() + e
    }
  }
  else{
    mockResponse.responseContent = ""
  }
}
else{
  mockResponse.responseContent = "File does not exist!"
  
}

        Binary is needed to support all kind of file types (.txt, .pdf, .docx, etc)

        Also the code below doesn't work.

         

              com.eviware.soapui.impl.rest.mock.RestMockResult mockResult = mockResponse.getMockResult()
      InputStream inputS = new ByteArrayInputStream(fileBytes);
      long length=fileBytes.length
      com.eviware.soapui.support.Tools.readAndWrite(inputS, length, mockResult.getOutputStream());
      inputS.close();

        When running, this exception is written to file:

        java.io.IOException: Closed
