Question

我想解码一个JSON格式的字符串，并通过MySQL将它插入SQL数据库。

import json
import MySQLdb as mdb

jsonofabitch = '{"timestamp":1479132183,"sn":"B59EC63F","u":[3346,3346,3347,3346],"soc":96,"i":-32,"cc":345351,"ccMax":360000}'

parsed_stuff = json.loads (jsonofabitch)

con = None

try:
    con = mdb.connect('localhost', 'name', 'password', 'mysql')
    cur = con.cursor()
    cur.execute("SELECT * FROM database")


    cur.execute("INSERT INTO database (timestamp, sn, u0, u1, u2, u3, soc, i, cc, ccMax) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)" % (parsed_stuff['timestamp'], parsed_stuff['sn'], parsed_stuff['u'[1]], parsed_stuff['u'[2]], parsed_stuff['u'[3]], parsed_stuff['u'[4]], parsed_stuff['soc'], parsed_stuff['i'], parsed_stuff['cc'], parsed_stuff['ccMax']))
    con.commit()

except mdb.Error as e:
     print("Error %d: %s" % (e.args[0], e.args[1]))
     sys.exit(1)

if con:
    con.close()

它抛出错误：

＆＃34;未知栏＆＃39; B59EC63F＆＃39;在＆＃39;字段列表＆＃39;＆＃34;

另外抛出

＆＃34; IndexError：字符串索引超出范围＆＃34;。

我改变了

VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)

到

VALUES (%s, '%s', %s, %s, %s, %s, %s, %s, %s, %s)

现在有效。

解码JSON-string并插入SQL数据库（sqlite3）
