我尝试使用ejabberd 17.04执行外部身份验证。但是我无法实现这一点，在ejabberd.log中我看到以下消息
@extauth：loop：141 extauth脚本突然出现原因＆＃39;正常＆＃39;
这是我的/opt/conf/ejabberd.yml外部身份验证的代码段：
auth_method: [external]
extauth_program: "php /opt/ejabberd-17.04/AuthExt.php"
extauth_instances: 3
auth_use_cache: false
AuthExt.php的代码片段如下：
#!/usr/bin/php

任何人都可以指出我使用ejabberd执行外部身份验证的正确方法。
谢谢，

如果您使用的是比5.4更新的php版本，那么您应该在脚本中删除此行，因为它已被弃用。
import csv, itertools
from math import floor
filename = 'denton_housing.csv'
denton_housing = {}
def create_nested_housing_dict():
with open(filename, 'r', encoding='utf8', newline='') as f:
for row in csv.DictReader(f, delimiter=','):
if row['year'] not in denton_housing: #UPDATE
denton_housing[row['year']] = {}
try:
denton_housing[row['year']][row['title_field']] = int(row['value'])
except KeyError:
denton_housing[row['year']] = {}
return denton_housing
data = create_nested_housing_dict()
for key, value in data.items():
print(key + ' ' + "{0:.0f}%".format(int(value['Vacant Housing Units'])) / \
int(value['Total Housing Units']) * 100 + key + ' ' + \
"{0:.0f}%".format(int(value['Occupied Housing Units'])) / \
int(value['Total Housing Units']) * 100)
