我得到一个包含图像字节的json数组。这个json数组嵌入在json对象中。当检查这个json数组中的元素类型时，它显示了类＆＃39; str＆＃39;。
我想将这些字节从json数组保存到不同的文件中。这就是我所做的。
images = []
images = data["Images"]
del data["Images"]
future = db.Document.insert(data)
result = yield future
if result:
index = 1
for image in images:
os.mkdir("/home/sandeep/Projects/PycharmProjects/Fortentia/src/Images/QID"+str(result))
f = open("/home/sandeep/Projects/PycharmProjects/Fortentia/src/Images/QID"+str(result)+"option"+str(index)+".jpg","wb")
f.write(image)
f.close()
index += 1
self.write("successful")
else:
self.write("Unsuccessful")
我正在和Motor一起使用龙卷风。
我得到的错误是：
