Python代码问题AttributeError：'NoneType' object没有属性'title'-Java 学习之路

我正在尝试运行以下代码，并且它始终与 Headers 中的错误失败：

Traceback（最近一次调用最后一次）：文件“/usr/local/lib/python2.7/dist-packages/cherrypy/_cprequest.py”，第670行，在响应中响应.body = self.handler（）文件“/ usr / local / lib / python2.7 / dist-packages / cherrypy / lib / encoding.py“，第217行，调用self.body = self.oldhandler（* args，** kwargs）文件”/ usr / local / lib / python2.7 / dist-packages / cherrypy / _cpdispatch.py“，第61行，在调用返回self.callable（* self.args，** self.kwargs）文件”web / 800-53-server.py“ ，第79行，在族中control_list.append（'％s-％d - ％s'％（id，control，id，control，sc.title.title））AttributeError：'NoneType'对象没有属性'title'

似乎错误的代码块如下：

@cherrypy.expose
def family(self, id="AC", format="html"):
    id = id.upper()
    family_control_count =  {"AC": 25, "AU": 16, "AT": 5, "CM": 11, "CP": 13, "IA": 11, "IR": 10, "MA": 6, "MP": 8,
        "PS": 8, "PE": 20, "PL": 9, "PM": 16, "RA": 6, "CA": 9, "SC": 44, "SI": 17, "SA": 22}
    families = {"AC": "Access Control", "AU": "Audit and Accountability", "AT": "Awareness and Training", "CM": "Configuration Management",
        "CP": "Contingency Planning", "IA": "Identification and Authentication", "IR": "Incident Response", "MA": "Maintenance",
        "MP": "Media Protection", "PS": "Personnel Security", "PE": "Physical and Environmental Protection", "PL": "Planning",
        "PM": "Program Management", "RA": "Risk Assessment", "CA": "Security Assessment and Authorization",
        "SC": "System and Communications Protection", "SI": "System and Information Integrity", "SA": "System and Services Acquisition"}

    control_list = []
    for control in range(1,family_control_count[id]+1):
        sc = SecControl("%s-%d" % (id, control))
        control_list.append('<div><a href="/control?id=%s-%d">%s-%d</a> - %s</div>' % (id, control, id, control, sc.title.title))

    return """<html>

更多以下程序：

`#!/usr/bin/python
# -*- coding: utf-8 -*-

import os, os.path
import sys
import random
import string
import json
import yaml
import cherrypy
from jinja2 import Environment, FileSystemLoader
env = Environment(loader=FileSystemLoader('web/templates'))

sys.path.append(os.path.join('lib'))
sys.path.append(os.path.join('data'))
from seccontrol import SecControl
from seccontrolviz import SecControlViz
from utilities import *


class StringGenerator(object):
    @cherrypy.expose
    def index(self):
        return """<html>
          <head>
            <title>800-53 Controls</title>
            <link rel="stylesheet" type="text/css" href="/assets/css/main.css">
          </head>`

包 GovReady （我假设这是基于import语句使用）依赖于 xsltproc . 您可能已将其安装在Mac OS上，但未安装在其他计算机上 . 它需要安装 sudo apt install xsltproc 或类似的Linux，因为它不是一个pip包 .

尝试从 800-53-server/lib 目录运行 xsltproc --stringparam controlnumber 'AC-1' control2json.xsl ../data/800-53-controls.xml . 您正在调用的函数是该命令的包装器 .

安装该程序后，我明白了
```
{ "id": "AC-1",
  "title": "ACCESS CONTROL POLICY AND PROCEDURES",
...
}
```
