我正在解析一个网站并想要插入到 MySQL。特定字段下的每个url需要解析6个字段。 有人知道如何使用 pymysql 将 MySQL 表转换为 Python 中的字典对象吗？
from bs4 import BeautifulSoup
import requests
import urllib.request
import pymysql
con = pymysql.connect(host = 'localhost',user = 'root',passwd = 'root',db = 'm_db')
cursor = con.cursor(pymysql.cursors.DictCursor)
with open(r"C:\New folder\urllist.txt") as f:
urls = [u.strip('\n') for u in f.readlines()]
page = 0
while page < 5:
try:
soup = BeautifulSoup(requests.get(urls[page]).content, "html.parser")
text = soup.select("head script[type=text/javascript]")[-1].text
start = text.find('dataLayer = [') + len('dataLayer = [')
end = text.rfind('];')
rows = text[start:end].strip().split('\n')
except:
pass
for d in rows:
cursor.execute("INSERT INTO micro (d['brand'], d['productPrice'], d['SKU'], d['productID'], d['mpn'], d['ean'], ) VALUES (%s,%s,%s,%s,%s,%s)",(d['brand'], d['productPrice'], d['SKU'], d['productID'], d['mpn'], d['ean']))
d = cursor.fetchall()
con.commit()
page = page + 1
如何使用我拥有的数据填充 SQL 插入语句。 这是我的数据
{
'brand':'Fluke',
'productPrice':'2199.99',
'SKU':'34353362',
'productID':'443329',
'mpn':'RT-AC3200',
'ean':'886290480914',
}
它会产生此错误
Traceback (most recent call last): File "C:/PycharmProjects/untitled4/m_new.py", line 22,
in <module> cursor.execute("INSERT INTO micro (d['brand'], d['productPrice'], d['SKU'], d['productID'], d['mpn'], d['ean'], ) VALUES (%s,%s,%s,%s,%s,%s)",(d['brand'], d['productPrice'], d['SKU'], d['productID'], d['mpn'], d['ean']))
TypeError: string indices must be integers
最佳答案
您的 SQL 查询不正确。应该是
cursor.execute("INSERT INTO micro (brand, productPrice, SKU, productID, mpn, ean) VALUES (%s,%s,%s,%s,%s,%s)",(d['brand'], d['productPrice'], d['SKU'], d['productID'],d['mpn'], d['ean']))
