AttributeError: 'bytes' object has no attribute 'getPage'
Question
Ive done some coding. Html and flask. Accepting pdf file from a form and watermark it using flask.
Here is my html coding:
<!DOCTYPE html>
<html>
<body>
<p>Click on the "Choose File" button to upload a file:</p>
<form action="/upload_file" method="POST" enctype = "multipart/form-data">
<input type="file" name="file">
<input type="submit">
</form>
</body>
</html>
Here is my flask coding:
@app.route('/upload_file', methods=['POST'])
def upload_file():
pdf_file = request.files['file']
watermark = "watermark.pdf"
merged_file = "merged.pdf"
input_pdf= pdf_file.read()
#input_pdf = PyPDF2.PdfFileReader(open(pdf_file,'rb'))
watermark_file = open(watermark,'rb')
watermark_pdf = PyPDF2.PdfFileReader(watermark_file)
pdf_page = input_pdf.getPage(0)
watermark_page = watermark_pdf.getPage(0)
pdf_page.mergePage(watermark_page)
output = PyPDF2.PdfFileWriter()
output.addPage(pdf_page)
merged_file = open(merged_file,'wb')
output.write(merged_file)
merged_file.close()
watermark_file.close()
input_pdf.close()
return "Success"
Traceback:

The relevant code is:
input_pdf= pdf_file.read()
pdf_page = input_pdf.getPage(0)
From a commented-out line ( input_pdf = PyPDF2.PdfFileReader(open(pdf_file,'rb')) ), it looks like you probably want to create a PdfFileReader object based on pdf_file. Since pdf_file is a file, try:
input_pdf = PyPDF2.PdfFileReader(pdf_file) # changed from pdf_file.read()
pdf_page = input_pdf.getPage(0)
