UnicodeEncodeError: 'latin-1' codec can't encode character 解决sae flask 中文问题

#encoding=utf-8
#中文编码支持

import MySQLdb
from flask import Flask, g, request

app = Flask(__name__)
app.debug = True

from sae.const import (MYSQL_HOST, MYSQL_HOST_S,
    MYSQL_PORT, MYSQL_USER, MYSQL_PASS, MYSQL_DB
)

@app.before_request
def before_request():
    g.db = MySQLdb.connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASS,
                           MYSQL_DB, port=int(MYSQL_PORT))
#g.db.set_character_set('utf8')

g.db.set_character_set('utf8') 这句话加上去就OK了。

以下是网上的方案原帖。

"UnicodeEncodeError:'latin-1' codec can't encode character ..."

This is because MySQLdb normally tries to encode everythin to latin-1. This can be fixed by executing the following commands right after you've etablished the connection:

db.set_character_set('utf8')
dbc.execute('SET NAMES utf8;') dbc.execute('SET CHARACTER SET utf8;')
dbc.execute('SET character_set_connection=utf8;')

"db" is the result of MySQLdb.connect, and "dbc" is the result of db.cursor().

意思就是MySQLdb正常情况下会尝试将所有的内容转为latin1字符集处理

所以处理方法就是，设置连接和游标的charset为你所希望的编码，如utf8

db是connection连接，dbc是数据库游标
