我想為從 Django 專案打開 pdf 檔案添加密碼保護。
def pdf_view(request):
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="members.pdf"'
elements = []
doc = SimpleDocTemplate(response, rightMargin=0.5 * cm, leftMargin=6.5 * cm, topMargin=0.3 * cm, bottomMargin=0)
rows = []
users = User.objects.all()
for user in users:
rows.append((
user.username,
user.email,
user.first_name,
user.last_name,
formats.date_format(user.date_joined, "SHORT_DATETIME_FORMAT"),
formats.date_format(user.subscriptions.current_period_end, "SHORT_DATETIME_FORMAT")
))
table = Table(rows, colWidths=46 * mm, rowHeights=30, repeatRows=1)
table.setStyle([
('GRID', (0, 0), (-1, -1), 0.25, colors.black),
("ALIGN", (0, 0), (-1, -1), "LEFT"),
])
table = Table(rows, colWidths=46 * mm, rowHeights=30, repeatRows=1)
elements.append(table)
doc.build(elements)
return response
我在哪里可以添加這行代碼來進行加密
pdfencrypt.StandardEncryption("password", canPrint=0)
任何幫助都感激不盡
uj5u.com熱心網友回復：
您可以添加如下代碼行
def pdf_view(request):
response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="members.pdf"'
elements = []
**doc = SimpleDocTemplate(response, encrypt=pdfencrypt.StandardEncryption("pass", canPrint=0)**, rightMargin=0.5 * cm, leftMargin=6.5 * cm, topMargin=0.3 * cm, bottomMargin=0)
rows = []
users = User.objects.all()
for user in users:
rows.append((
user.username,
user.email,
user.first_name,
user.last_name,
formats.date_format(user.date_joined, "SHORT_DATETIME_FORMAT"),
formats.date_format(user.subscriptions.current_period_end, "SHORT_DATETIME_FORMAT")
))
table = Table(rows, colWidths=46 * mm, rowHeights=30, repeatRows=1)
table.setStyle([
('GRID', (0, 0), (-1, -1), 0.25, colors.black),
("ALIGN", (0, 0), (-1, -1), "LEFT"),
])
table = Table(rows, colWidths=46 * mm, rowHeights=30, repeatRows=1)
elements.append(table)
doc.build(elements)
return response
