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
