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 kno...

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

    I got it working:

    import javax.servlet.http.HttpServletResponse
import com.eviware.soapui.support.Tools
import com.eviware.soapui.impl.rest.mock.RestMockResult

def fileDir = context.mockService.getProperty("fileDir").value
def projectPath = (new  com.eviware.soapui.support.GroovyUtils(context)).projectPath
fileDir = fileDir.replace('$projectDir', projectPath)
fileDir = fileDir.replace("\\", "/")
def filename = requestContext.getProperty("filename")
def file = new File(fileDir + '\\' + filename)
def response = mockRequest.httpResponse
response.setContentType('application/octect-stream')
def headerKey = 'Content-Disposition'
def headerValue = 'attachment; filename="' + filename + '"'
response.addHeader(headerKey, headerValue)
if (file.exists() && file.isFile()){
  byte[] fileBytes = file.getBytes()
  if (fileBytes.length > 0){
    try{
      InputStream inputS = file.newInputStream()
    	 long length=file.length()
      response.setContentLength( ( int )length );
      Tools.readAndWrite(inputS, length, response.getOutputStream());
      inputS.close();
      return new com.eviware.soapui.impl.rest.mock.RestMockResult(mockRequest);
    }
    catch(Exception e){
      mockResponse.responseContent = "Exception:" + e.getMessage() + e
    }
  }
  else{
    mockResponse.responseContent = ""
  }
}
else{
  mockResponse.responseContent = "File does not exist!"
  
}

      Your example from post 5 helped me to sent back a non plain text file like PDF / ZIP / JPEG or whatever, Tools.readAndWrite was the key.

      But due to my project usage after successfully sent back the response with

      "return new com.eviware.soapui.impl.rest.mock.RestMockResult(mockRequest);"

      my SoapUI has thrown the Exception "Failed to find MockResonse"

       

      I had to change the call of Response.

      Instead of return directly the content, I put the output stream response.getOutputStream()) into a requestContext variable:

       

            Tools.readAndWrite(inputS, length, response.getOutputStream());
      inputS.close();
      requestContext.myResponse = response.getOutputStream();
      return "MockResponse";

       

      The "MockResponse" below the MockAction contains as Body only

      ${myResponse}

       

      No error log entry anymore and everything works as expected. :smileyhappy:
