从一个页面重定向到另一页面以及Flask中的一些POST数据 [英] Redirect from one page to another along with some POST data in Flask

问题描述

我正在做一个Flask项目.成功执行登录功能后，应在主页上重定向一些数据.数据应邮寄.怎么办?

I am working on a Flask project. After successful execution of login function, it should redirect on home page with some data. The data should be send by post. How can this be done??

推荐答案

要成功登录后发送数据，可以在 redirect 之内使用 url_for ，如下所示:

For send data after successful login you can use url_for within of redirect something as this:

@app.route('/login', methods = ['POST'])
def login():
    if request.method == 'POST' and request.form.get("username") == 'admin':
        return redirect(url_for('success',data=request.form.get("data")),code=307)
    else:
        return redirect(url_for('index'))

成功登录后，您可以使用您的数据发送 data = data ，因此在其他视图中您可以获取该数据.

After success login you can use your data to send with data=data, so in your other view you get that data.

@app.route("/test/argument", methods=['POST'])
def success():
    messages = request.form.get('data')  # counterpart for url_for()
    return messages
