关于#python#的问题：分割连续json

Question

#如何用python分割多个连接起来的json
（求问）
现有一个字符串如(是由两个json无缝连接而成):

{"cmd":"ONLINE_RANK_COUNT","data":{"count":236},"is_report":false,"msg_id":"875144313051649","send_time":1690223085309}{"cmd":"ENTRY_EFFECT","data":{"basemap_   _url":"https://i0.hdslb.com/bfs/live/mlive/6d38ab463be28a130870c8c43d109473f215963e.png","business":4,"copy_color":"#ffffff","copy_writing":"欢迎\u003c%唐周很乖y%\u003e进入直播间","copy_writing_v2":"欢迎\u003c%唐周很乖y%\u003e进入直播间","effect_silent_time":0,"effective_time":3,"effective_time_new":0,"face":"https://i1.hdslb.com/bfs/face/d2003a3bb5933d03ed25ac5106d8c046d9101563.jpg","highlight_color":"#ffea18","icon_list":[],"id":253,"identities":1,"max_delay_time":7,"mobile_dynamic_url_webp":"","mock_effect":0,"new_style":0,"priority":1,"privilege_type":0,"show_avatar":1,"target_id":1869286411,"trigger_time":1690223084898894800,"uid":3493291370744671,"wealthy_info":null,"web_basemap_url":"https://i0.hdslb.com/bfs/live/mlive/6d38ab463be28a130870c8c43d109473f215963e.png","web_close_time":900,"web_dynamic_url_apng":"","web_dynamic_url_webp":"","web_effect_close":1,"web_effective_time":3},"is_report":false,"msg_id":"875144677431296","send_time":1690223086004} 

该怎么将它分割成:

{"cmd":"ONLINE_RANK_COUNT","data":{"count":236},"is_report":false,"msg_id":"875144313051649","send_time":1690223085309}

和

{"cmd":"ENTRY_EFFECT","data":{"basemap_   _url":"https://i0.hdslb.com/bfs/live/mlive/6d38ab463be28a130870c8c43d109473f215963e.png","business":4,"copy_color":"#ffffff","copy_writing":"欢迎\u003c%唐周很乖y%\u003e进入直播间","copy_writing_v2":"欢迎\u003c%唐周很乖y%\u003e进入直播间","effect_silent_time":0,"effective_time":3,"effective_time_new":0,"face":"https://i1.hdslb.com/bfs/face/d2003a3bb5933d03ed25ac5106d8c046d9101563.jpg","highlight_color":"#ffea18","icon_list":[],"id":253,"identities":1,"max_delay_time":7,"mobile_dynamic_url_webp":"","mock_effect":0,"new_style":0,"priority":1,"privilege_type":0,"show_avatar":1,"target_id":1869286411,"trigger_time":1690223084898894800,"uid":3493291370744671,"wealthy_info":null,"web_basemap_url":"https://i0.hdslb.com/bfs/live/mlive/6d38ab463be28a130870c8c43d109473f215963e.png","web_close_time":900,"web_dynamic_url_apng":"","web_dynamic_url_webp":"","web_effect_close":1,"web_effective_time":3},"is_report":false,"msg_id":"875144677431296","send_time":1690223086004} 

分割完后可以用json.loads()那种

Answer 1

import json

def multijson_gen(multijson):
    while True:
        try:
            obj = json.loads(multijson)
            yield obj
            return
        except json.JSONDecodeError as e:
            json_str = multijson[:e.pos]
            multijson = multijson[e.pos:]
            if json_str == "":
                return
            yield json.loads(json_str)
