json字符串轉(zhuǎn)字典? ?loads

json_str = '{"a":1, "b":2, "c":True, "d":Null}'

data_dict = json.loads(json_str)

字典轉(zhuǎn)json? ?dumps

data_dict =?{ "b":2, "c":True, "d":Null, "e":"張三", "f":[1,2,3], "a":1}

json_str = json.dumps(data_dict, indent=2, ensure_ascii=False, sort_keys=True)

indent=2? 每一級(jí)會(huì)縮進(jìn)2；?

?ensure_ascii 默認(rèn)為T(mén)rue，會(huì)把中文轉(zhuǎn)換為二進(jìn)制（因?yàn)閡rl傳遞的都是二進(jìn)制），如果不想轉(zhuǎn)換為為二進(jìn)制，設(shè)置為False；

sort_keys 默認(rèn)為False，設(shè)置為T(mén)ure后會(huì)按照Ascii排序，a就會(huì)一直在上面
