请问这个code,payload()输出的是什么类型的数据啊？

请问这个扫码识别得到的code.payload（）,扫码结果是123+321 ,我将它赋值给message，然后通过比对message是否等于字符串123+321，一直显示不相等，请问这个code,payload()输出的是什么类型的数据啊？

while(b==1):
    img = sensor.snapshot()
    img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens.
    for code in img.find_qrcodes():
        img.draw_rectangle(code.rect(), color = (255, 0, 0))
        message = code.payload()
        if message =='123+321'
               print("0")

就是字符串，估计你的代码写错了，或者是二维码错了。

# QRCode Example

# This example shows the power of the OpenMV Cam to detect QR Codes
# without needing lens correction.

import sensor, image, time

sensor.reset()
sensor.set_pixformat(sensor.GRAYSCALE)
sensor.set_framesize(sensor.VGA)
sensor.set_windowing((240, 240)) # look at center 240x240 pixels of the VGA resolution.
sensor.skip_frames(time = 2000)
sensor.set_auto_gain(False) # must turn this off to prevent image washout...
clock = time.clock()

while(True):
    clock.tick()
    img = sensor.snapshot()
    for code in img.find_qrcodes():
        if code.payload() == '123+321':
            print("yes")
