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": "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：
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(':')
