所以我正在尝试让自动完成与python-ldap和flask一起使用。 下面是一个测试脚本 ldapA.py：
import ldap
#first you must open a connection to the server
def query():
try:
l = ldap.open("server.net")
## searching doesn't require a bind in LDAP V3. If you're using LDAP v2, set the next line appropriately
## and do a bind as shown in the above example.
# you can also set this to ldap.VERSION2 if you're using a v2 directory
# you should set the next option to ldap.VERSION2 if you're using a v2 directory
l.protocol_version = ldap.VERSION3
l.set_option(ldap.OPT_REFERRALS, 0)
username="CN=user user,OU=bbbgbg,OU=bdbfd,DC=dsffd,DC=net"
passw="adsada"
l.simple_bind_s(username,passw)
except ldap.LDAPError, e:
print e
# handle error however you like
## The next lines will also need to be changed to support your search requirements and directory
baseDN = "ou=xds, ou=sd, dc=sd, dc=net"
searchScope = ldap.SCOPE_SUBTREE
## retrieve all attributes - again adjust to your needs - see documentation for more options
retrieveAttributes = ['name']
searchFilter = "name=*jace*"
try:
ldap_result_id = l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
result_set = []
while 1:
result_type, result_data = l.result(ldap_result_id, 0)
if (result_data == []):
break
else:
## here you don't have to append to a list
## you could do whatever you want with the individual entry
## The appending to list is just for illustration.
if result_type == ldap.RES_SEARCH_ENTRY:
result_set.append(result_data)
res = result_set[0]
res1 = res[0]
res2 = res1[1]
res3 = res2["name"]
print res3[0]
except ldap.LDAPError, e:
print e
query()
当我运行它时，它按预期工作。它给了我广告中我的名字。
现在，当我像这样从烧瓶中调用它时：
from flask import render_template
from app import app
from flask import request
from ldapA import query
@app.route('/')
@app.route('/index')
def index():
return render_template("index.html")
@app.route('/autocomplete', methods=['GET'])
def autocomplete():
return query()
我得到：
127.0.0.1 - - [19/Jul/2017 14:08:58] "GET /autocomplete HTTP/1.1" 500 -

我知道这条线会导致麻烦：
ldap_result_id = l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
但是我很困惑为什么它在烧瓶中调用时会发生，而不是在使用python ldapA.py 运行时发生。 这似乎是 ldap lib 内部错误，但为什么它只发生在烧瓶中，我该如何解决它？ 谢谢大家！
事实证明，这是一个 unicode 问题，对于任何有相同错误的人来说： 转到 ldpaobject.py(您在哪里安装了python-ldap( 改变
if PY2:
text_type = unicode
else:
text_type = str
到只是
text_type = str
python-LDAP 现在应该在 Flask 中工作
