Question

这是我在MYSQL中插入推文数据的代码

import pymysql
import tweepy
import time
import json
from tweepy import Stream
from tweepy import OAuthHandler
from tweepy.streaming import StreamListener
import pymysql.cursors

ckey= ''
csecret= ''
atoken=''
asecret=''

conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='admin1234', db='mysql')
cur = conn.cursor()

class listener(StreamListener):

 def on_data(self, data):
        all_data = json.loads(data)
        tweet = all_data["text"]
        a=0
        #username = all_data["user"]["screen_name"]

        cur.execute("INSERT INTO tweet (textt) VALUES (%s)" (tweet))
        print (tweet)
        return True

def on_error(self, status):
    print (status)

auth = OAuthHandler(ckey, csecret)
auth.set_access_token(atoken, asecret)
twitterStream = Stream(auth, listener())
twitterStream.filter(track = ["puasa"])

cur.close()
conn.close()

但我收到错误TypeError: 'str' object is not callable

Answer 1

您需要额外2个逗号：

cur.execute("INSERT INTO tweet (textt) VALUES (%s)", (tweet,))

第一个将查询字符串与参数分开，第二个将括号中的值转换为1个元素元组中的第一个元素（如果您只使用单个字符串而不是元组，则实际为would work，假设你只有一个参数，但从事物的外观来看，这并没有得到官方支持。

但是您在评论中提到的这个错误：

UnicodeEncodeError: 'latin-1' codec can't encode character '\u201c' in position 97: ordinal not in range(256)

表示您尝试将包含扩展字符集中的字符的unicode文本解释为latin-1。

如果该字段已在内部定义（在您的mysql数据库中）为unicode，则可能需要指定连接时使用的字符集，例如：

conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='admin1234', db='mysql', use_unicode=True, charset="utf8")

如果mysql中的字段不是像utf-8那样，那么我建议你改变或以其他方式重新定义数据库，以便为此列使用unicode字符。
