從jquery中檢索python中的post變量

我是一個python新手。我試圖用python來查詢數據庫。我需要傳遞一些參數到python頁面，以便它可以查詢數據庫。但是我無法檢索後期變量。從jquery中檢索python中的post變量

HTML：

<select class="chooseRace" id="race"> 
        <option value="president">Presidential</option> 
        <option value="governor">Gubernatorial</option> 
        <option value="senate">Senatorial</option> 
</select>

的jQuery：

var e = document.getElementById("race"); 
var strRace = e.options[e.selectedIndex].value; 

$.ajax({ 
    url: "http://localhost/py/getRaces.py", 
    method: "POST", 
    data: {level: strLevel}, 
    success: function(data) { 
     // Successful POST; do something with the response if you want 
     console.log("ok, it worked. "); 
    }, 
    error: function(jxhr, statusText, err) { 
     // Error, handle it 
     console.log(statusText + " " + err); 
    } 
});

蟒蛇：

import MySQLdb 
import cgitb 
cgitb.enable() 
import json 
import requests 

print "Content-Type: text/html"  # HTML is following 
print 
print request.POST['level'] # for POST form method 

db = MySQLdb.connect(host="localhost", # your host, usually localhost 
        user="user", # your username 
         passwd="pass", # your password 
         db="my_dbs") # name of the data base 

cur = db.cursor() 

cur.execute("SELECT * FROM mytable")

但是當我運行本地主機/ PY/getRaces.py，我得到這個：

<type 'exceptions.NameError'> Python 2.7.8: C:\Python27\python.exe 
Tue Jul 22 14:58:21 2014 
A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred. 

C:\code\getRaces.py in() 
     7 print "Content-Type: text/html"  # HTML is following 
     8 print 
=> 9 print request.POST['level'] # for POST form method 
    10 
    11 db = MySQLdb.connect(host="localhost", # your host, usually localhost 
request undefined 
<type 'exceptions.NameError'>: name 'request' is not defined 
     args = ("name 'request' is not defined",) 
     message = "name 'request' is not defined"

任何人都知道我在做什麼錯了？我以爲我安裝了請求庫。

它不應該是如下：

print requests.post['level'] # for POST form method

該錯誤消息表示，有沒有這樣的事情在你的程序的要求「。

我改變了行來打印requests.POST ['level']，錯誤信息是：'module'對象沒有屬性'POST' – LauraNMS

編輯我的答案;沒有考慮到區分大小寫。 –

會導致錯誤：：'function'object has no attribute'__getitem__' args =（「'function'object has no attribute'__getitem__'」，） message =「'function'object沒有屬性'__getitem__'「 – LauraNMS

您正在使用哪種框架？

您試圖訪問應該保存您收到的數據的對象，但它沒有在函數作用域中定義或根本不存在於您的框架中。
