Im解析一個網站,並希望插入到MySQL。有6個字段需要在特定字段下解析每個網址。 任何人都知道我可以如何使用pymysql將一個MySQL錶轉換爲Python中的字典對象?使用pymysql來插入表
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
我該如何填充SQL插入語句與我有的數據。 這裏是數據我有
{
'brand':'Fluke',
'productPrice':'2199.99',
'SKU':'34353362',
'productID':'443329',
'mpn':'RT-AC3200',
'ean':'886290480914',
}
它產生這個錯誤
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
當您運行此代碼會發生什麼?輸出?你到底在找什麼? – r0xette
@ r0xette這裏是什麼接收 回溯(最近呼叫最後): 文件「C:/PycharmProjects/untitled4/m_new.py」,第22行,在 cursor.execute(「INSERT INTO micro(d ['brand '],d ['productPrice'],d ['SKU'],d ['productID'],d ['mpn'],d ['ean'],)VALUES(%s,%s,%s, %'s','d','['品牌'],d ['productPrice'],d ['SKU'],d ['productID'],d ['mpn'],d [ ean'])) TypeError:字符串索引必須是整數 –

您沒有從MySQL讀取數據,因此您的問題「如何使用pymysql將MySQL錶轉換爲字典對象」沒有任何意義 – e4c5
