问题描述
我正在尝试使用 Flask 将 HTML 转换为 pdf。
我可以使用以下软件包。
- pdfkit
- wkhtmltopdf
当我运行服务器时，它无法加载到浏览器中，甚至主页也无法加载到浏览器中。我不明白这有什么问题。
HTML 标记：
<!DOCTYPE html>
<html lang="en">
<head>
<Meta charset="UTF-8">
<Meta http-equiv="X-UA-Compatible" content="IE=edge">
<Meta name="viewport" content="width=device-width,initial-scale=1.0">

</head>
<body>
<div class="container">
<h1 class="text-center mt-4">Leave Workers Details</h1>
<table class="table mt-4">
<thead class="table-dark">
<tr>
<th scope="col">Id</th>
<th scope="col">Name</th>
<th scope="col">Address</th>
<th scope="col">Contact</th>
<th scope="col">LeaveDate</th>
<th scope="col">Admin</th>
</tr>
</thead>
{% for worker in leave_worker %}
<tbody>
<tr>
<td> {{ worker.id }}</td>
<td> {{ worker.leave_worker_name }} </td>
<td> {{ worker.leave_worker_address }} </td>
<td> {{ worker.leave_worker_contact }} </td>
<td> {{ worker.leave_date.strftime('%Y-%m-%d') }} </td>
<td> {{ worker.admin.username }} </td>
</tr>
</tbody>
{% endfor %}
</table>
</div>
</body>
</html>
route.py 代码：
config = pdfkit.configuration(wkhtmltopdf='C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe')
pdfkit.from_url('http://127.0.0.1:5000/leave_worker_pdf','output.pdf',configuration=config)
@app.route('/leave_worker_pdf')
def leave_worker_pdf():
leave_worker = LeaveWorker.query.all()
html = render_template(
"leave_worker_pdf.html",leave_worker=leave_worker)
pdf = pdfkit.from_string(html,False)
response = make_response(pdf)
response.headers["Content-Type"] = "application/pdf"
response.headers["Content-disposition"] = "inline; filename=output.pdf"
return response
解决方法
改变
def leave_worker_pdf():
leave_worker = LeaveWorker.query.all()
html = render_template(
"leave_worker_pdf.html",leave_worker=leave_worker)
pdf = pdfkit.from_string(html,False)
response = make_response(pdf)
response.headers["Content-Type"] = "application/pdf"
response.headers["Content-Disposition"] = "inline; filename=output.pdf"
return response
到
@app.route('/leave_worker_pdf')
def leave_worker_pdf():
leave_worker = LeaveWorker.query.all()
html = render_template(
"leave_worker_pdf.html",False)
response = make_response(pdf)
response.headers["Content-Type"] = "application/pdf"
response.headers["Content-Disposition"] = "inline; filename=output.pdf"
return response
这假设您使用的是 app 而不是蓝图。
