Question

考虑到下面的路由，我发现如果参数 test 具有默认值，则通过 url_for 传递值时它不会改变>和重定向。我想要的是在渲染模板时更改参数 test ，具体取决于是否刚刚提交了表单。

@app.route('/view_story/<story_id>', methods=['GET', 'POST'])
def view_story(story_id, test='no'):
    ...
    if current_user.is_authenticated:
        if request.method == 'POST':
            #Add stuff to database from the form. 
            return redirect(url_for('view_story', story_id=story_id, test='yes'))

    return render_template('story.html', test=test)

Answer 1

尝试以下代码：

@app.route('/view_story/<story_id>', defaults={"test": "no"})
@app.route('/view_story/<story_id>/<test>', methods=['GET', 'POST'])
def view_story(story_id, test):
    ...
    if current_user.is_authenticated:
        if request.method == 'POST':
            #Add stuff to database from the form. 
            return redirect(url_for('view_story', story_id=story_id, test='yes'))

    return render_template('story.html', test=test)

烧瓶重路由始终使用默认函数参数
