折腾：
【已解决】Mac中启动uiautomator2的weditor界面调试环境
期间，后续去刷新页面，结果报错：

表面上看是缺少了个d
但是感觉好像是由于 Pillow的PIL的image保存图片时出错的呢
像是之前自己遇到的：
【已解决】Python自动化安卓游戏测试报错：cannot write mode RGBA as JPEG
去看看代码：
venv/lib/python3.8/site-packages/uiautomator2/__init__.py
@retry((IOError, SyntaxError), delay=.5, tries=5, jitter=0.1,
max_delay=1, logger=logging) # delay .5, .6, .7, .8 ...

format (str): used when filename is empty. one of ["pillow", "opencv", "raw"]

cv2.imwrite('saved.jpg', screenshot(format='opencv'))
"""
# print("filename=%s, format=%s" % (filename, format))
# print("before /screenshot/0: %s" % datetime.now())
beforeSceenshotTime = datetime.now()
# print("beforeSceenshotTime=%s" % beforeSceenshotTime)
r = self.http.get("/screenshot/0", timeout=10)
# print("after /screenshot/0: %s" % datetime.now())
afterSceenshotTime = datetime.now()
# print("afterSceenshotTime=%s" % afterSceenshotTime)

f.write(r.content)
afterSaveFileTime = datetime.now()

# print("save file time: %s" % saveFileTime)
return filename
elif format == 'pillow':
buff = io.BytesIO(r.content)
# print("after io.BytesIO: %s" % datetime.now())
try:

rgbImg = Image.open(buff).convert("RGB")
# print("after convert RGB: %s" % datetime.now())
return rgbImg

raise IOError("PIL.Image.open IOError", ex)
return Image.new("RGB", self.window_size(), (220, 120, 100))
elif format == 'opencv':
import cv2
import numpy as np
nparr = np.fromstring(r.content, np.uint8)
# print("before cv2.imdecode: %s" % datetime.now())
decodedImage = cv2.imdecode(nparr, cv2.IMREAD_COLOR)

return decodedImage
elif format == 'raw':
print("before resp content: %s" % datetime.now())
return r.content
else:
raise ValueError("Invalid format {}".format(format))
正好是最近调试过的代码。
if d.settings['fallback_to_blank_screenshot']:
去找了下，别处都是
self.settings
所以去改为：
if self.settings['fallback_to_blank_screenshot']:
估计就可以了。
但是此处只是解决了语法错误，没有解决逻辑错误：
依旧是去img转换报错的。
把自己的代码合并过来
jpegNotSupportFormatList = ["RGBA", "P"]
originImg = Image.open(buff)
if originImg.mode in jpegNotSupportFormatList:
originImg = originImg.convert("RGB")但是突然发现，其本身就是去转换为RGB的
算了， 还是去调试，看看：
if self.settings['fallback_to_blank_screenshot']:
raise IOError("PIL.Image.open IOError", ex)抛出的异常具体是啥
不过发现代码：
originImg = Image.open(buff)
print("originImg.mode=%s" % originImg.mode)
jpegNotSupportFormatList = ["RGBA", "P"]
if originImg.mode in jpegNotSupportFormatList:
originImg = originImg.convert("RGB")
rgbImg = originImg
# print("after convert RGB: %s" % datetime.now())
return rgbImg已经可以正常工作了：
[I 201211 16:37:54 page:297] Serial: android:2e2a0cb1 filename=None, format=pillow originImg.mode=RGBA [I 201211 16:37:55 web:2242] 200 GET /api/v1/devices/android%3A2e2a0cb1/screenshot (::1) 976.28ms
没问题了。
可以截图了：
【总结】
目前是把之前代码：
venv/lib/python3.8/site-packages/uiautomator2/__init__.py
elif format == 'pillow':
buff = io.BytesIO(r.content)
# print("after io.BytesIO: %s" % datetime.now())
try:
# print("before convert RGB: %s" % datetime.now())
rgbImg = Image.open(buff).convert("RGB")
# print("after convert RGB: %s" % datetime.now())
return rgbImg
except IOError as ex:
# Always fail in secure page
# 截图失败直接返回一个粉色的图片
# d.settings['default_screenshot'] =
if d.settings['fallback_to_blank_screenshot']:
raise IOError("PIL.Image.open IOError", ex)
return Image.new("RGB", self.window_size(), (220, 120, 100))改为：
elif format == 'pillow':
buff = io.BytesIO(r.content)
# print("after io.BytesIO: %s" % datetime.now())
try:
# print("before convert RGB: %s" % datetime.now())
# rgbImg = Image.open(buff).convert("RGB")
originImg = Image.open(buff)
print("originImg.mode=%s" % originImg.mode)
jpegNotSupportFormatList = ["RGBA", "P"]
if originImg.mode in jpegNotSupportFormatList:
originImg = originImg.convert("RGB")
rgbImg = originImg
# print("after convert RGB: %s" % datetime.now())
return rgbImg
except IOError as ex:
# Always fail in secure page
# 截图失败直接返回一个粉色的图片
# d.settings['default_screenshot'] =
# if d.settings['fallback_to_blank_screenshot']:
if self.settings['fallback_to_blank_screenshot']:
raise IOError("PIL.Image.open IOError", ex)
return Image.new("RGB", self.window_size(), (220, 120, 100)) 即可：正常截图了。
