你可以使用 PyPDF2 来完成这个任务：
import PyPDF2
def add_custom_property(pdf_path, property_name, property_value):
with open(pdf_path, "rb") as file:
pdf_reader = PyPDF2.PdfReader(file)
pdf_writer = PyPDF2.PdfWriter()
[pdf_writer.add_page(page) for page in pdf_reader.pages]
pdf_writer.add_metadata(
{
f"/{property_name}": property_value,
**pdf_reader.metadata,
}
)
output_path = "modified_" + pdf_path
with open(output_path, "wb") as output_file:
pdf_writer.write(output_file)
add_custom_property("test.pdf", "institution", "stack overflow")

You can use PyPdf2 to do that:
import PyPDF2
def add_custom_property(pdf_path, property_name, property_value):
with open(pdf_path, "rb") as file:
pdf_reader = PyPDF2.PdfReader(file)
pdf_writer = PyPDF2.PdfWriter()
[pdf_writer.add_page(page) for page in pdf_reader.pages]
pdf_writer.add_metadata(
{
f"/{property_name}": property_value,
**pdf_reader.metadata,
}
)
output_path = "modified_" + pdf_path
with open(output_path, "wb") as output_file:
pdf_writer.write(output_file)
add_custom_property("test.pdf", "institution", "stack overflow")
