我正在尝试根据用户输入编辑可编辑 pdf 上的复选框。我可以使用 pdfrw 编辑文本字段,如下所示:https ://bostata.com/how-to-populate-fillable-pdfs-with-python/
#! /usr/bin/python
import os
import pdfrw
INVOICE_TEMPLATE_PATH = 'invoice_template.pdf'
INVOICE_OUTPUT_PATH = 'invoice.pdf'
ANNOT_KEY = '/Annots'
ANNOT_FIELD_KEY = '/T'
ANNOT_VAL_KEY = '/V'
ANNOT_RECT_KEY = '/Rect'
SUBTYPE_KEY = '/Subtype'
WIDGET_SUBTYPE_KEY = '/Widget'
def write_fillable_pdf(input_pdf_path, output_pdf_path, data_dict):
template_pdf = pdfrw.PdfReader(input_pdf_path)
annotations = template_pdf.pages[0][ANNOT_KEY]
for annotation in annotations:
if annotation[SUBTYPE_KEY] == WIDGET_SUBTYPE_KEY:
if annotation[ANNOT_FIELD_KEY]:
key = annotation[ANNOT_FIELD_KEY][1:-1]
if key in data_dict.keys():
annotation.update(
pdfrw.PdfDict(AP=data_dict[key], V=data_dict[key])
)
pdfrw.PdfWriter().write(output_pdf_path, template_pdf)
data_dict = {
'business_name_1': 'Bostata',
'customer_name': 'company.io',
'customer_email': 'joe@company.io',
'invoice_number': '102394',
'send_date': '2018-02-13',
'due_date': '2018-03-13',
'note_contents': 'Thank you for your business, Joe',
'item_1': 'Data consulting services',
'item_1_quantity': '10 hours',
'item_1_price': '$200/hr',
'item_1_amount': '$2000',
'subtotal': '$2000',
'tax': '0',
'discounts': '0',
'total': '$2000',
'business_name_2': 'Bostata LLC',
'business_email_address': 'hi@bostata.com',
'business_phone_number': '(617) 930-4294'
}
if __name__ == '__main__':
write_fillable_pdf(INVOICE_TEMPLATE_PATH, INVOICE_OUTPUT_PATH, data_dict)
但是,我仍然无法保存对复选框值的更改。在本地,我可以看到输出文件中复选框的更改。但是,当我将文件上传到 AWS S3 存储桶时,不会保存更改。我不确定问题是什么。任何帮助,将不胜感激。谢谢!
