python3 json数据包含中文的读写问题

python3 默认的是UTF-8格式，但在在用dump写入的时候仍然要注意：如下

import jsondata1 = {    "TestId": "testcase001",    "Method": "post",    "Title": "登录测试",    "Desc": "登录基准测试",    "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)

在打开文件的时候要加上encoding=‘utf-8’，不然会显示成乱码，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的时候也加上ensure_ascii=False,不然会变成ascii码写到文件中，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文件写中文的时候也要注意在打开的时候加上encoding=‘utf-8’，不然也是乱码，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(':')
