为什么demo的语义解析打开之后是这样的：  {"content":{"item":["搜索微信"],"json_res":"{\"parsed_text\":\"搜索 微 信\",\"raw_text\":\"搜索微信\",\"results\":[{\"domain\":\"app\",\"intent\":\"search\",\"object\":{\"_appname\":\"微信\",\"appname\":\"微信\"},\"score\":0.650},{\"domain\":\"search\",\"intent\":\"search\",\"object\":{\"_content\":\"微信\",\"content\":\"微信\"},\"score\":0.350}]}\n"},"result":{"corpus_no":6363796564710386869,"err_no":0,"idx":-15,"res_type":3,"sn":"1a5fdcc9-72ee-4a6e-bc8f-434380f160af"}}

而我自己获取的时候是这样的：{"content":{"item":["帮我搜索微信"],"json_res":"{\"parsed_text\":\"帮 我 搜索 微 信\",\"raw_text\":\"帮我搜索微信\",\"results\":[]}\n"},"result":{"corpus_no":6363793999807262279,"err_no":0,"idx":-16,"res_type":3,"sn":"154b731f-cba1-4714-9a17-55a229c8a45c"}}

是少传了什么参数导致的吗？
