I have encountered the problem to write Base64image data on FTP. When I write it on local drive, The photo is appeared clearly. But, When I write it on FTP server, it's appeared like spoiled images. when I write it on local drive, it's shown like this enter image description here I have attached the picture on FTP . enter image description here
Here is my code.
private static String testFilesDir = "C:\\Storage";
public String getIncidentPhotoByID(int incident_id, int photoId) {
String base64Image = null;
WebSSLClient client = new WebSSLClient();
Response response =client.createRequest(PropertiesUtil.getOracleCloudRestUrL() + "/mobile/platform/storage/collections/incident_photos_collection/objects/incident_462_03").get();
String jsonResponse = response.readEntity(String.class);
base64Image = jsonResponse;
FTPClient ftp = new FTPClient();
FileInputStream fis = null;
String filename = "incident_462_03";
String[] strings = base64Image.split(",");
String extension;
switch (strings[0]) {//check image's extension
case "data:image/jpeg;base64":
extension = "jpeg";
break;
case "data:image/png;base64":
extension = "png";
break;
default://should write cases for more images types
extension = "jpg";
break;
}
//convert base64 string to binary data
byte[] data1 = Base64.decodeBase64(strings[1]);
/*
String path = testFilesDir+"/"+filename+"."+ extension;
File file = new File(path);
try (OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(file))) {
outputStream.write(data1);
} catch (IOException e) {
e.printStackTrace();
} */
try {
ftp.connect("link.myjpl.com");
ftp.login("user", "password");
String path = "Images/test/"+filename+"."+ extension;
OutputStream out1 = ftp.storeFileStream(path);
out1.write(data1);
ftp.logout();
} catch (IOException e) {
e.printStackTrace();
}
return base64Image;
}
}
Try setting the fileType to FTP.BINARY_FILE_TYPE. Also as per the javadocs, to finalize the file transfer you must call completePendingCommand and check its return value to verify success.
