所以我試圖使用python-ldap和flask來自動完成。 這是一個測試腳本ldapA.py:當在燒瓶中調用時,Python ldap函數的行爲有所不同
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()
它按預期工作當我運行它。它給了我我的名字來自公元。
現在,當我把它從燒瓶這樣的:
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 -

我知道這行導致的麻煩:
ldap_result_id = l.search(baseDN, searchScope, searchFilter, retrieveAttributes)
但我m難以理解爲什麼它在瓶子中調用時發生,而不是在用python ldapA.py運行時發生。 它似乎是ldap lib內部錯誤,但爲什麼它只發生在燒瓶中,我怎麼修復它? 謝謝你們!
您不會在查詢方法中返回任何內容。在你的瓶子自動填充方法中,你正在返回查詢的結果,這是什麼?如果你想獲得打印結果,把它放在一個變量中並返回。 – user1408786
@ user1408786我可以在函數中添加一些返回值,但它仍然會給出相同的錯誤,這只是爲了調試目的,它甚至從不會返回到返回值,因爲它會在中間引發異常。 –
