TypeError(repr(o) + " is not JSON serializable")

self.request = Request(url, data = json.dumps(data), headers = {"Content-Type": "application/json"})

json.dumps(data)

也碰到这个问题。
不过我改了代码。百度的post data规格改了。
data = {
"format": "pcm",
# "lan": self.language,
"token": self.token,
"len": len(audio_data.data),
# "rate": audio_data.rate,
"rate": 8000,
"channel" : 1,
"speech": base64.b64encode(audio_data.data),
"cuid": '93489083242',
}

不过出现另外一个问题
with sr.WavFile(WAV_FILE) as source:
audio = r.record(source) # read the entire WAV file
读不出数据！！！
audio为空！！
