Question

我有一个python程序，其中我访问一个URL并提取数据。然后我将这些数据输入到mysql表中。 mysql表有pid ,position,club, points,s,availability, rating,name列。我对python程序没有任何问题（我希望），但数据库显然似乎不接受UTF字母ex: Jääskeläinen的名称。如何使数据库接受这些名称？我尝试使用here给出的答案。但该程序仍然给我以下错误：

Traceback (most recent call last):
  File "C:\Users\GAMER\Desktop\Padai\Fall 13\ADB\player_extract.py", line 49, in <module>
    sql += "('{0}', '{1}', '{2}', '{3}', '{4}','{5}','{6}','{7}')".format(count,position,club, points,s,availability, rating,name)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 1-2: ordinal not in range(128)
excepted Goalkeepers Jääskeläinen West Ham 67 £5.5

我的python代码就是这个“

# -*- coding: utf-8 -*-
from bs4 import BeautifulSoup
from urllib import urlopen
from pprint import pprint
import MySQLdb
import traceback
import re
#fetch players list from site

url = "http://fantasy.premierleague.com/player-list/"
html = urlopen(url).read()


soup = BeautifulSoup(html)
h2s = soup.select("h2")
tables = soup.select("table")

first = True
title =""
players = []
for i,table in enumerate(tables):
    if first:
         title =  h2s[int(i/2)].text
    for tr in table.select("tr"):
        player = (title,)
        for td in tr.select("td"):
            player = player + (td.text,)
        if len(player) > 1:
            players.append(player)

    first = not first

##SQL connectivity and data entry

db = MySQLdb.connect(host="localhost", user="root", passwd="hassan28", db = "adbpro")

cur = db.cursor()

try:
    count = 1
    for i in players:
        position, name, club, points, price = i
        s = price[1:]
        name = name.replace("'"," ")
        rating = 4
        availability = 1
        sql = "INSERT INTO players (pid,position,club,points,price,availability,rating,name) VALUES "
        try:
            sql += "('{0}', '{1}', '{2}', '{3}', '{4}','{5}','{6}','{7}')".format(count,position,club, points,s,availability, rating,name)
            cur.execute(sql)
            count +=1
        except UnicodeError:
            traceback.print_exc()
            print "excepted", position, name, club, points, price
            continue
        #print sql

    db.commit()

except:
    print sql
    traceback.print_exc()
    db.rollback()
    cur.execute("SELECT * FROM PLAYERS")


print "done"

非常感谢任何帮助。

似乎是this question的副本。仅针对其他人，解决方案是“当您connect()到您的数据库时，传递charset='utf8'参数。”

Answer 2

这不是数据库问题;您正在尝试将Unicode值插入到字节字符串中，从而触发隐式编码。

此处不要使用字符串格式，而是使用SQL参数：

sql = "INSERT INTO players (pid,position,club,points,price,availability,rating,name) VALUES (%s, %s, %s, %s, %s, %s, %s, %s)"
params = (count, position, club, points, s, availability, rating, name)
cur.execute(sql, params)

此处%s告诉MySQLdb期望SQL参数的位置，并将参数作为单独的列表传递给cursor.execute()。

请记住告诉数据库连接您要将UTF-8用于Unicode值：

db = MySQLdb.connect(host="localhost", user="root", passwd="hassan28", 
                     db="adbpro", charset='utf8')

SQL数据库不接受UTF -8字符
