想要用pywebview+flask做一个小demo,代码如下:import flask
import webview
app = flask.Flask(__name__)
@app.route('/')
def home_page():
return flask.render_template('index.html')
@app.route('/admin/', methods=['GET', 'POST'])
def hello_admin():
if flask.request.form['password'] == '229773fxy':
return "welcome, admin!"
else:
return "warning, wrong password, please check your password again"
if __name__ == '__main__':
window = webview.create_window(
title='demo',
url=app,
confirm_close=True
)
cn = {
'global.quitConfirmation': u'确定关闭?'
}
webview.start(localization=cn, gui='mshtml')
index.html内容如下:<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="http://127.0.0.1:5000/admin/" method="post">
<p>Enter Password:</p>
<input type="password" name="password" />
<br>
<input type="submit" value="done"/>
</form>
</body>
</html>
但当我按下“done”按钮后,显示无法访问此页面(也就是https://127.0.0.1:5000/admin/这个网址)
我自己的想法是,可能flask服务没有开启,所以无法访问
但如果在代码中加上app.run(__name__)时,主进程被阻塞,gui界面没有出现
我想使用multiprocessing把flask服务放到另一个进程运行,结果失败了:Traceback (most recent call last):

实在没办法,有没有人知不知道如何解决? |
