我需要幫助在 android Studio 中使用 JAVA 將 pdf 文件上傳到解析服務(wù)器。我嘗試使用以下代碼：private ParseObject uploadPDFToParse(File PDFFile, ParseObject po, String columnName){ if(PDFFile != null){ Log.d("EB", "PDFFile is not NULL: " + PDFFile.toString()); ByteArrayOutputStream out = new ByteArrayOutputStream(); BufferedInputStream in = null; try { in = new BufferedInputStream(new FileInputStream(PDFFile)); } catch (FileNotFoundException e) { e.printStackTrace(); } int read; byte[] buff = new byte[1024]; try { while ((read = in.read(buff)) > 0) { out.write(buff, 0, read); } } catch (IOException e) { e.printStackTrace(); } try { out.flush(); } catch (IOException e) { e.printStackTrace(); } byte[] pdfBytes = out.toByteArray(); // Create the ParseFile ParseFile file = new ParseFile(PDFFile.getName() , pdfBytes); po.put(columnName, file); // Upload the file into Parse Cloud file.saveInBackground(); po.saveInBackground(); } return po;}

嘗試以下代碼并讓我知道：
private ParseObject uploadPDFToParse(File PDFFile, ParseObject po, String columnName){
if(PDFFile != null){
Log.d("EB", "PDFFile is not NULL: " + PDFFile.toString());
int size = (int) file.length();
byte[] pdfBytes = new byte[size];
try {
BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
buf.read(pdfBytes, 0, pdfBytes.length);
buf.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// Create the ParseFile
ParseFile file = new ParseFile(PDFFile.getName() , pdfBytes);
po.put(columnName, file);
// Upload the file into Parse Cloud
file.save();
po.saveInBackground();
}
return po;
}
