python - 为什么这个 python 脚本不会输入到我设置的 MySQL 表中？

Question

我正在尝试将 YouTube API 中的数据提取到本地 MySQL 表中。我经历了一堆调试，直到我登陆下面的脚本，但我没有从这个脚本中得到任何错误，所以我有点迷茫。任何人有任何建议从哪里开始？

#!/usr/bin/python
# -- coding: utf-8 --

import MySQLdb
import os
import requests
import json
import sys
import re
import requests
import datetime

sql_conn = MySQLdb.connect(host="localhost", user="root", passwd="PSWD", db="researchyoutube")
sql_conn.autocommit(True)
sql_db = sql_conn.cursor(MySQLdb.cursors.DictCursor)

resp = requests.get("https://gdata.youtube.com/feeds/api/videos?q=kitten&orderby=published&start-index=11&max-results=50&v=2&alt=jsonc")

if(resp.status_code == 200):
    data = json.loads(resp.content) 
    for item in data['data']['items']:

        title = item['title']
        uploaded_on = item['uploaded']
        description = item['description']
        video_length = item['duration']
        user = item['uploader']
        video_id = item['id']
        video_url = item['player']['default']

        sql = "INSERT IGNORE into NCII (title, uploaded_on, description, video_length, user, video_id, video_url) VALUES (title, uploaded_on, description, video_length, user, video_id, video_url)"

        sql_db.execute(sql)

Answer 1

看起来您的VALUES()列表包含变量名称而不是适当的%s占位符

sql = "INSERT IGNORE into NCII (title, uploaded_on, description, video_length, user, video_id, video_url) VALUES (%s, %s, %s, %s, %s, %s, %s)"

# execute with the vars in a tuple
sql_db.execute(sql, (title, uploaded_on, description, video_length, user, video_id, video_url))
