我试图将一个参数从文本输入形式传递到我的app.py中，但出现以下错误消息：
不允许的方法所请求的URL不允许使用此方法。
这里是我的app.py配置：
@main_blueprint.route('/reports/daily_reports')
def downloadsss():
if request.method == 'GET':
daily_path = "./app/templates/Repo/DailyReports"
daily_listOfFiles = os.listdir(daily_path)
return render_template('main/DailyReports.html', len = len(daily_listOfFiles), daily_listOfFiles
= daily_listOfFiles)
elif request.method == 'POST' and 'download' in request.form:
download = request.form.get('download')
path = 'C:/Users/Ahmed Mustafa/FlaskProject/app/templates/Repo/DailyReports/' + download
return send_file(path, as_attachment=True)
以下是我的HTML代码：
{% extends "main/main_base.html" %} {# main/main_base.html extends layout.html #}
{% block content %}
<head>
<style>
body {background-color: powderblue;}
h1 {color: blue;}
p {color: red;}
h2 {color: black; font-size: 20px; font-family: "Lucida Sans Unicode", "Lucida Grande", sans-
serif;}
th {vertical-align: top; align-items: center;}
table{align-items: center; }
</style>
<div class="jumbotron text-center">
<p><font size="6">This page is to show the Daily Reports list!</font></p>
<form method="post">
<input type="text" name="download" />
<input type="submit" value="Download" />
</form>
<!-- For loop logic of jinja template -->
<li class="list-group-item"><font size="6">
{% print('Total Number of Reports:'), len %}</font></li>
<div align="left" >
{%for i in range(0, len)%}
{% print('Report Number:'),[i+1] %}
<li class="list-group-item">
