内容导读

互联网集市收集整理的这篇技术教程文章主要介绍了python-枕头返回错误：“ IOError：图像文件被截断(6个字节未处理)”，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含4306字，纯文字阅读大概需要7分钟。

内容图文

我将Pillow 4.1.1与Python 2.7 / Django 1.9一起使用

我的网站上有成千上万张用户上传的图片,我使用枕头从模板生成缩略图.

例如.：

{% thumbnail apicture.file "1200x350" crop="center" as im %}
    <img src="{{ im.url }}" width=100%>
{% endthumbnail %}

直到本周为止,它的运转情况都很好. Django现在显示此错误：

IOError: image file is truncated (6 bytes not processed)

在stackoverflow上找到的解决方案不起作用,因为它们都适用于视图而不是模板(例如ImageFile.LOAD_TRUNCATED_IMAGES = True).

有没有一种简单的方法来识别哪些图片会产生此错误？如何解决这个错误？

这是完整的回溯：

谢谢

解决方法:

好的,我得到了我自己问题的答案！

正如lepsch所说,只需添加

从PIL导入Image,ImageFile
ImageFile.LOAD_TRUNCATED_IMAGES =真

尽早在Django应用中.我将其添加到生成页面的视图中,并且工作正常.
