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 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：
{
"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(':')
