解決python3 json數據包含中文的讀寫問題

Posted on by

python3 默認的是UTF-8格式，但在在用dump寫入的時候仍然要註意：如下

import json
data1 = {
 "TestId": "testcase001",
 "Method": "post",
 "Title": "登錄測試",
 "Desc": "登錄基準測試",
 "Url": "http://xxx.xxx.xxx.xx",
 "InputArg": {
  "username": "王小丫",
  "passwd": "123456",
 },
 "Result": {
  "errorno": "0"
 }
}
with open('casedate.json', 'w', encoding='utf-8') as f:
  json.dump(data1, f, sort_keys=True, indent=4)

在打開文件的時候要加上encoding=‘utf-8’，不然會顯示成亂碼，如下：

{
 "Desc": "��¼��׼����",
 "InputArg": {
  "passwd": "123456",
  "username": "��СѾ"
 },
 "Method": "post",
 "Result": {
  "errorno": "0"
 },
 "TestId": "testcase001",
 "Title": "��¼����",
 "Url": "http://xxx.xxx.xxx.xx"
}

在dump的時候也加上ensure_ascii=False,不然會變成ascii碼寫到文件中，如下：

{
 "Desc": "\u767b\u5f55\u57fa\u51c6\u6d4b\u8bd5",
 "InputArg": {
  "passwd": "123456",
  "username": "\u738b\u5c0f\u4e2b"
 },
 "Method": "post",
 "Result": {
  "errorno": "0"
 },
 "TestId": "testcase001",
 "Title": "\u767b\u5f55\u6d4b\u8bd5",
 "Url": "http://xxx.xxx.xxx.xx"
}

另外python3在向txt文件寫中文的時候也要註意在打開的時候加上encoding=‘utf-8’，不然也是亂碼，如下：

with open('result.txt', 'a+', encoding='utf-8') as rst:
  rst.write('return data')
  rst.write('|')
  for x in r.items():
    rst.write(x[0])
    rst.write(':')
