python - Flask 的 url_for 引发 TypeError : 'function' object has no attribute '__getitem__'

Question

我正在尝试为我的详细信息路由生成一个 url 并重定向到它。我调用 redirect(url_for(details))，但得到 TypeError: 'function' object has no attribute '__getitem__'。我做错了什么？

@app.route('/search_process')
def search():
    return redirect(url_for(details))

@app.route('/details')
def details():
    return 'details'

Traceback (most recent call last):

    return self.wsgi_app(environ, start_response)

    response = self.make_response(self.handle_exception(e))

TypeError: 'function' object has no attribute '__getitem__'

您需要将端点名称(一个字符串)传递给 url_for。

return redirect(url_for('details'))
