在Flask中，如何在单击按钮时生成动态URL?

问题描述

例如，现在，如果我在表单元素中有两个按钮，则单击它们中的任何一个时，您将被定向到相应的配置文件.

For example, now if I have two buttons in a form element, when you click on either one of them, you'll be directed to the corresponding profile.

<form action="{{ url_for('getProfile') }}" method="post">
    <button type="submit" name="submit" value="profile1"> View Profile</button>
    <button type="submit" name="submit" value="profile2"> View Profile</button>
</form>

在我的apprunner.py中，

In my apprunner.py, I have

 @app.route('/profile', methods=['POST'])
 def getProfile():
       if request.form['submit'] = 'profile1':
            return render_template("profile1.html")
       else if request.form['submit'] = 'profile2':
            return render_template("profile2.html")

但是，我的问题是，当我单击任一按钮时，URL总是像"127.0.0.1:5000/profile"之类的东西.但是，我希望它看起来像" http://127.0.0.1:5000/profile1 "或" http://127.0.0.1:5000/profile2 ".

However, my problem is when I click on either button, the url will always be something like "127.0.0.1:5000/profile". But, I want it to look like "http://127.0.0.1:5000/profile1" or "http://127.0.0.1:5000/profile2".

我一直在寻找有关如何在线生成动态URL的解决方案，但是它们都不适合单击按钮.

I have looked for solution on how to generate dynamic URL online, but none of them works for button click.

提前谢谢！

推荐答案

@app.route('/profile<int:user>')
def profile(user):
    print(user)

您可以在REPL上对其进行测试:

You can test it on a REPL:

import flask
app = flask.Flask(__name__)

@app.route('/profile<int:user>')
def profile(user):
    print(user)

ctx = app.test_request_context()
ctx.push()

flask.url_for('.profile', user=1)
'/profile1'

如何将 user 参数传递到新路由取决于您的需求.如果您需要 profile1 和 profile2 的硬编码路由，则可以分别传递 user = 1 和 user = 2 .如果要以编程方式生成这些链接，请取决于这些配置文件的存储方式.

how you pass the user parameter to your new route depends on what you need. If you need hardcoded routes for profile1 and profile2 you can pass user=1 and user=2 respectively. If you want to generate those links programatically, depends on how these profiles are stored.

否则，您可以将请求对象中已解析的元素重定向而不是 render_template 重定向到 url_for .这意味着有两条路线

Otherwise you could redirect instead of render_template, to the url_for with the parsed element in the request object. This means having two routes

@app.route('/profile<int:user>')
def profile_pretty(user):
    print(user)

@app.route('/profile', methods=['POST'])
def getProfile():
      if request.form['submit'] = 'profile1':
           return redirect(url_for('.profile_pretty', user=1))
       else if request.form['submit'] = 'profile2':
            return redirect(url_for('.profile_pretty', user=2))

如 http://exploreflask.com/en/latest/views.html#url-converters

@app.route('/user/<username>')
def profile(username):
    pass

@app.route('/user/id/<int:user_id>')
def profile(user_id):
    pass

我们还可以使用第二个视图来查找字符串.将会为/user/id/Q29kZUxlc3NvbiEh/调用，而第一个会为/user/id/124调用.

We could have a second view that looks for a string as well. That would be called for /user/id/Q29kZUxlc3NvbiEh/ while the first would be called for /user/id/124.
