python腳本的問題

我已經遇到了另一個問題，下面給出的代碼我無法登錄，它仍然說訪問被拒絕，即使用戶名和密碼是正確的。控制檯上沒有錯誤。看起來我在連接後錯過了一些東西。python腳本的問題

我所要做的就是修改TODO部分，以便它在連接和成功登錄後對我的Oracle數據庫運行計算的查詢時，它應該顯示權限表的結果。

import cgi 
import cx_Oracle 

print("Content-type: text/html\n") 
print("<title>Test</title>") 
print("<body><center>") 

try: 
    # get post data 
    form = cgi.FieldStorage() 
    name = form['name'].value if 'name' in form else '' 
    pwd = form['pwd'].value if 'pwd' in form else '' 

    permissions = [] 
    # query to check password and get permissions 
    query = "SELECT PERMISSIONS FROM USERS WHERE NAME='{}' and PWD='{}'".format(name, pwd) 

    # TODO: connect to database and run query 
    host = '123.abc.com' 
    port = 1521 
    SID = 'orcl' 
    dsn_tns = cx_Oracle.makedsn(host, port, SID) 

    connection = cx_Oracle.connect('abuser', 'userpass', dsn_tns) 
    curs = connection.cursor() 
    result = curs.execute(query) 

    # TODO section ends 

    if len(permissions) > 0: 
     print("<H1>Access granted. You have the following permissions: {}.</H1>".format(permissions[0][0])) 
    else: 
     print("<H1>Access denied.</H1>") 
    connection.close()  
except cx_Oracle.DatabaseError as e: 
    # for ease of debugging 
    print("Database Error: {}".format(e)) 
    print("<br>Query: {}".format(query)) 

print(""" 
<form action="../login.html" method="GET"> 
    <input type="submit" value="Back to Login"> 
</form> 
""") 

print('</center></body>')

非常感謝，它排序我的問題:) –

你縮進太大起始線36（我猜你上傳的部分源代碼），在那裏它開始host =
