Question

所以当我在我的控制台中运行它时，我有一段代码可以正常工作，但是当我尝试在app引擎上运行它时，它不会。

from lib.PIL import Image
import urllib, cStringIO
@endpoints.method(ImageCreateRequest, DummyResponse, http_method='POST', name='image_create')
def image_create(self, request):
    file = cStringIO.StringIO(urllib.urlopen(URL).read())
    img = Image.open(file)
    img.load()
    return DummyResponse(
        response=str(img.size)
    )

我收到以下错误

in _new

new.mode = im.mode

AttributeError: 'NoneType' object has no attribute 'mode'

编辑：确切追溯

Encountered unexpected error from ProtoRPC method implementation: AttributeError ('NoneType' object has no attribute 'mode')

AttributeError：'NoneType'对象没有属性'mode'

我不太确定为什么这么简单的东西会在控制台中运行而不是在app引擎上运行。有什么想法吗？

如果是生产问题，你应该试试这个 - 从您自己安装的lib文件夹中删除PIL模块。

转到app.yaml并将其粘贴到库部分下（如果没有粘贴整个部分） -

from src.models.base import Base

通过 -

调用基于appengine的模块

libraries:
  - name: PIL
    version: latest

在应用引擎
