Question

我是一个蟒蛇新手。我试图使用python来查询数据库。我需要将一些参数传递给python页面，以便它可以查询数据库。但我在检索帖子变量方面遇到了麻烦。

HTML：

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

jquery的：

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：

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")

但是当我运行localhost / py / getRaces.py时，我得到了这个：

<type 'exceptions.NameError'>   Python 2.7.8: C:\Python27\python.exe

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"

任何人都知道我做错了什么？我以为我安装了请求库。

Answer 1

不应该是以下内容：

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

错误消息表明您的程序中没有“请求”这样的内容。

Answer 2

您使用的是哪个框架？

您正在尝试访问应保存已接收数据的对象，但它未在功能范围内定义或在您的框架中根本不存在。
