[已解决]Flask的Jinja中如何实现页面跳转

Flask crifan 1636浏览 0评论

之前静态页面中,是通过:

<a href="creatEvent.html" class="link icon-only" class="external">
    <img src="{{ url_for(‘static’, filename=’img/avatar/navi_add_lightblue_24x24.svg’) }}"/>
</a>

实现页面跳转的到:

creatEvent.html

但是现在在Flask中,点击无效。

且希望,同时传递对应的参数user_openid

Flask jinja 页面跳转

Flask jinja jump page

Flask jinja redirect  page

flask跳转页面参数加上#? – SegmentFault

jinja redirect  page

jinja2 – Flask 手机版和PC版模板的代码设计问题 – SegmentFault

Flask 使用小结【Updating】 – leejun2005的个人页面 – 开源中国社区

redirect(url_for(‘foo’))

但是是在.py中实现的。

此处是需要在template的html中实现页面跳转

Simple Pagination | Flask (A Python Microframework)

[AF] Use Jinja to redirect to a page:flask

python – How can I "redirect" to another URL and pass a list object using Flask – Stack Overflow

->好像是:

template的html中,用:

url_for(“creatEvent")

然后在views.py中加上对应的路由,在路由中,render_templte

python – How do I create a link to another html page? – Stack Overflow

->果然是这个思路

但是还是不会传递参数啊

google app engine – Python jinja2 redirect with passing a parameter – Stack Overflow

 jinja redirect url_for

python – Can’t pass a variable with Jinja in Flask – Stack Overflow

python – Flask url_for() with multiple parameters – Stack Overflow

python – Creating link to an url of Flask app in jinja2 template – Stack Overflow

然后此处,可以实现页面跳转了:

/Users/crifan/dev/dev_root/daryun/SIPEvents/sourcecode/flask/sipevents/templates/index.html

<a href="{{ url_for(‘creatEvent’, curUser = curUser) }}" class="link icon-only" class="external">

然后,对应的

/Users/crifan/dev/dev_root/daryun/SIPEvents/sourcecode/flask/sipevents/views.py

@app.route(‘/creatEvent’, methods=[‘GET’, ‘POST’])
def creatEvent():
    requestMethod = request.method
    app.logger.debug(‘requestMethod=%s’, requestMethod)
    requestArgs = request.args
    app.logger.debug(‘requestArgs=%s’, requestArgs)
    curUser = request.args.get("curUser", "")
    app.logger.debug(‘curUser=%s’, curUser)
    if request.method == ‘POST’:
        return redirect(url_for(‘index’))
    else:
        return render_template("creatEvent.html", curUser = curUser)

然后对于页面:

点击右上角的加号,可以接收到对应的参数,且是GET方法,

可以从对应的打印出来的log中看出来:

DEBUG in views [/root/html/SIPEvents/sipevents/views.py:298]:
requestMethod=GET

<div–<——————————————————————————

<div–<——————————————————————————

DEBUG in views [/root/html/SIPEvents/sipevents/views.py:300]:
requestArgs=ImmutableMultiDict([(‘curUser’, u"<User nickname=u’\\u793c\\u8c8c’ openid=oswjmv4X0cCXcfkIwjoDfCkeTVVY avatar_static_path=img/avatar/oswjmv4X0cCXcfkIwjoDfCkeTVVY.png>")])

<div–<——————————————————————————

<div–<——————————————————————————

DEBUG in views [/root/html/SIPEvents/sipevents/views.py:302]:
curUser=<User nickname=u’\u793c\u8c8c’ openid=oswjmv4X0cCXcfkIwjoDfCkeTVVY avatar_static_path=img/avatar/oswjmv4X0cCXcfkIwjoDfCkeTVVY.png>

对应的跳转到新页面:

然后也是可以接收到对应的传入到参数:curUser对象的。

[总结]

Flask的Jinja中,从页面1,比如index.html,跳转到新页面页面2,比如createEvent,可以:

1.在template的html中,用:

<a href="{{ url_for(’someRounterInFlask’, parameter1 = value1) }}" >

2.在对应的Flask的路由,比如views.py中,加上对应的路由

然后其中可以调用render_template,加上对应的页面的2的模板,就可以跳转页面了:

@app.route(‘/creatEvent’, methods=[‘GET’, ‘POST’])
def creatEvent():
    requestMethod = request.method
    app.logger.debug(‘requestMethod=%s’, requestMethod)
    requestArgs = request.args
    app.logger.debug(‘requestArgs=%s’, requestArgs)
    value1 = request.args.get("parameter1", "")
    app.logger.debug(‘value1=%s’, value1)
    if request.method == ‘POST’:
        return redirect(url_for(‘index’))
    else:
        return render_template("creatEvent.html", curUser = curUser)
