Python ldap函数在flask中调用时的行为不同
因此,我正在尝试使用python ldap和flask实现自动完成。 下面是一个测试脚本ldapA.py:Python ldap函数在flask中调用时的行为不同,python,flask,ldap,python-ldap,Python,Flask,Ldap,Python Ldap,因此,我正在尝试使用python ldap和flask实现自动完成。 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 L
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。广告上写着我的名字
现在,当我从烧瓶中这样称呼它:
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:

我知道这条线路引起了麻烦:
ldap_result_id = l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
但我不明白为什么在flask中调用时会发生这种情况,而在使用pythonldapa.py运行时不会发生这种情况。
这似乎是ldap lib内部错误,但为什么它只发生在flask中,我如何修复它?
谢谢大家 对于任何有相同错误的人来说,这都是一个unicode问题: 转到ldpaobject.py(安装了python ldap的服务器) 改变 公正
text_type = str
python ldap现在应该可以在flask中工作了对于任何有相同错误的人来说,这都是一个unicode问题: 转到ldpaobject.py(安装了python ldap的服务器) 改变 公正

python ldap现在应该可以在flask中工作了在查询方法中不返回任何内容。在flask autocomplete方法中,您返回的是查询结果,这是什么?如果你想得到打印结果,把它放在一个变量中并返回它。@ USER 140888.我可以在函数中添加一些返回,但是它仍然给出相同的错误,这只是出于调试的目的,它甚至不会返回,因为它在中间抛出异常。在查询方法中,你不返回任何东西。在flask autocomplete方法中,您返回的是查询结果,这是什么?如果你想得到打印结果,把它放在一个变量中并返回它。@ USER 140888.我可以在函数中添加一些返回,但是它仍然给出相同的错误,这只是出于调试的目的,它甚至不会返回,因为它在中间抛出异常。
