Python requests.post 发送中文 'latin-1' codec can't encode characters in position 57-62:

 headers = {"Content-type": "application/json;charset=utf-8", "Authorization": "bearer " + token}
    data = {

        'upstreamTaskId': taskid,

    data = json.dumps(data, ensure_ascii=False)
    response = requests.post(url, data=data, headers=headers, timeout=600, verify=False).content.decode('utf8')

报错：Python requests.post 发送中文 'latin-1' codec can't encode characters in position 57-62: Body ('元素认知服务') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

data = json.dumps(data, ensure_ascii=False)改成

data = json.dumps(data, ensure_ascii=False).encode("utf-8")
