有报错，不知道是咋回事，大神能指导一下么

出现这个说明没问题了，因为那个接口只有答题的时候有数据，所以平时会报这个错误

[p1094358629]

关于这个错误，我看了源码不是很明白，是什么事件开始出发截屏的呢？？？ 我们运行main之后，系统系统在干什么呢？？？

[steveyg]

@p1094358629 是这样的，这个脚本分为两个模式，一种是截屏，一种是调接口，出现这个问题是因为接口没有数据导致的，如果是截屏模式，截屏在Img_utils中的spot中调用

[p1094358629]

@steveyg 我昨天在公司的时候用您的项目，模式是冲顶大会的，当我运行main.py,貌似进程会等待msg，有数据就会直接跳到web。而今天这个如果没有msg，直接报题目这个错？？？我需要不停的运行main.py,请问这是为什么呢？？？

[steveyg]

@p1094358629 我也发现了这个问题，正在排查中

[p1094358629]

@steveyg 您这个api 挺有意思的啊，能看下源码吗？？？

[steveyg]

@p1094358629 api是别人提供的，见https://github.com/steveyg/AnswerHelper/issues/1

[steveyg]

问题已修复，原因是之前访问太频繁导致报了403错误 修改见https://github.com/steveyg/AnswerHelper/commit/8594421edc059435dd8fb554c84ebc952f0d0b61

好像今天晚上答题接口一直返回没数据

[steveyg]

嗯，获取题目的接口好像用不了了，先暂时用ocr的方式吧

[fcc04101405]

靠度娘解决了。。。 改了一下Image.py的tostring方法的代码，注释掉了上面这句，改成了return self.tobytes()

[steveyg]

这是库的问题？

[fcc04101405]

好像是，百度好像说得pillow版本3.0以下，以上的好像tostring就不支持。。。
