我目前在我的烧瓶网络应用程序上有一个表单，它有 +- 100 个输入。要请求 1 行中的每个值，我使用：f = request.form. 如果我在我的本地版本上打印它，我最终会按完整顺序得到我所有值的完整列表：

ImmutableMultiDict([('intro1', 'hello'), ('intro2', 'eargr'), ('intro3', 'rferferaf'), ('intro4', 'eragaerg'), ('intro5', 'aergferaf'), ('intro6', 'aerfa'), ('intro7', 'faf'),`('intro8', 'fazfa'), ('intro9', 'f'), ('intro10', 'f'), ('intro11', 'f'), ('intro12', 'ezfzef'),` ('intro13', 'f'), ('liab1', ''), ('liab2', 'hello'), 
    ('liab3', ''), ('liab4', 'nvion'),....

如果我在我的实时版本上打印它，它会以完全随机的顺序返回它：

ImmutableMultiDict([('liab43', 'hello'), ('pl33', ''), ('inv3', ''), ('fin5', ''), ('inv10', ''), `('pl44', ''), ('liab46', ''), ('liab17', ''), ('liab49', ''), ('intro10', 'ovov o'), ('fin9', ''), ('pl30', ''), ('pl15', ''), ('liab10', ''), ('pl34', 'hello'), ('pl24', ''), ('intro13', 'nvion'), ('liab31', ''), ('pl39', ''), ('intro3', 'zenfoczoi'), ('liab1', ''), ('inv15', ''), ('pl16', ''), ('liab50', ''), ('intro1', 'hello'), ('intro8', 'connfvo'), ('pl38', ''), ('fin4', ''), ('pl49', ''), ('pl21', ''), ('fin6', ''), ('intro2', 'hefhuze'), ('liab22', ''), ('pl61', ''), ('pl18', ''), ('fin10', ''), ('liab53', ''), ('liab30', ''),`

我怎样才能解决这个问题？因为两个版本完全一样，没有区别。本地版本在 Windows 上，实时版本在使用 nginx 和 gunicorn 的 Debian VPS 上。

默认情况下，当您调用时request.form，Flask 返回一个ImmutableMultiDict（不可变字典），但如果您希望数据按顺序排列，您也可以让它返回ImmutableOrderedMultiDict（有序不可变字典）。只需这样做：

from flask import Flask, Request
from werkzeug.datastructures import ImmutableOrderedMultiDict

class MyRequest(Request):
    """Request subclass to override request parameter storage"""
    parameter_storage_class = ImmutableOrderedMultiDict

class MyFlask(Flask):
    """Flask subclass using the custom request class"""
    request_class = MyRequest

app = MyFlask(__name__)
