在Windows上使用bat呼叫python指令碼時出現報錯、亂碼

Python指令碼內容是將excel轉為csv

xlsx_to_csv.py

# -*- coding: gbk -*-
import codecs
import json

import xlrd
import datetime
import csv
import sys
reload(sys)
sys.setdefaultencoding('gbk')
print sys.getdefaultencoding()
def xlsx_to_csv():
    filename='E:\workspaces\test測試.xlsx
 
'
    workbook = xlrd.open_workbook(filename)
    
    # with codecs.open('fcc.csv', 'w', encoding='utf-8') as f:
    #     write = csv.writer(f)
    #     for row_num in range(table.nrows):
    #         row_value = table.row_values(row_num)
    #         write.writerow(row_value)
    sheet_names=workbook.sheet_names()
    
 
for i in range(len(sheet_names)):
        table = workbook.sheet_by_index(i)
        for row_num in range(0,table.nrows):
            row_value = table.row_values(row_num)
            # print row_value
            print sheet_names[i],",",json.dumps(row_value, ensure_ascii=False, encoding='utf-8')
        
 
# print str(row_value).encode('GB2312')  .decode('unicode_escape')
if __name__ == '__main__':
    xlsx_to_csv()

三處編碼相關設定：

1、指定檔案編碼

# -*- coding: gbk -*-

2、更改系統預設編碼

sys.setdefaultencoding('gbk')

3、json.dumps 序列化時對中文預設使用的ascii編碼，print json.dumps(row_value)輸出unicode編碼的結果

print json.dumps(row_value,ensure_ascii=False)不使用ascii編碼，而以gbk編碼 。

以下encoding指定為”utf-8"/"gbk"都可以。

json.dumps(row_value, ensure_ascii=False, encoding='utf-8')

不同配置下：

亂碼： ["鐗矽壊", "瀛楁1", "瀛楁2", "瀛楁3", "瀛楁4", "瀛楁5", "瀛楁6"]

亂碼：["\u7279\u8272", "\u5b57\u6bb51", "\u5b57\u6bb52", "\u5b57\u6bb53", "\u5b57\u6bb54", "\u5b57\u6bb55"]

報錯：UnicodeEncodeError: 'ascii' codec can't encode characters in position 25-32: ordinal not in range(128)
