python3 json数据包含中文的读

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

代码语言：javascript复制

import json
data1 = {
    "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：

代码语言：javascript复制

{
    "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：

代码语言：javascript复制

{
    "Desc": "u767bu5f55u57fau51c6u6d4bu8bd5",
    "InputArg": {
        "passwd": "123456",
        "username": "u738bu5c0fu4e2b"
    },
    "Method": "post",
    "Result": {
        "errorno": "0"
    },
    "TestId": "testcase001",
    "Title": "u767bu5f55u6d4bu8bd5",
    "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：

代码语言：javascript复制

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(':')

ascii
