我目前可以使用以下代码将OpenCV图像帧发送到我的Flask服务器

def sendtoserver(frame):
    imencoded = cv2.imencode(".jpg", frame)[1]
    headers = {"Content-type": "text/plain"}
    try:
        conn.request("POST", "/", imencoded.tostring(), headers)
        response = conn.getresponse()
    except conn.timeout as e:
        print("timeout")


    return response

但是我想发送一个unique_id以及我尝试使用JSON组合框架和ID的框架，但是遇到以下错误TypeError: Object of type 'bytes' is not JSON serializable，任何人都不知道我如何将一些其他数据与框架一起发送到服务器。

更新：

json格式代码

def sendtoserver(frame):
    imencoded = cv2.imencode(".jpg", frame)[1]
    data = {"uid" : "23", "frame" : imencoded.tostring()}
    headers = {"Content-type": "application/json"}
    try:
        conn.request("POST", "/", json.dumps(data), headers)
        response = conn.getresponse()
    except conn.timeout as e:
        print("timeout")


    return response
