如何在Django中显示内存中的图片? [英] How to display picture from memory in Django?

问题描述

我知道如何使用以下方式从内存中将图片显示为页面:

I know how to show picture as a page from memory just using like this:

import cStringIO

mStream = cStringIO.StringIO(picBin)

return HttpResponse(mStream.getvalue(),"image/jpg")

但是，如果我不想将图片显示为页面，而是想在页面中显示，例如使用HTML，有人知道如何设置图片"src"怎么办?是从内存加载的?

But what if I don't want to show the picture as a page, instead I want to show it within a page, say using in HTML, does someone has an idea what I should set the "src" if the picture is loaded from memory?

推荐答案

您需要对图像内容进行base-64编码到数据URI :

You'll need to base-64 encode the image contents into a Data URI:

data_uri = 'data:image/jpg;base64,'
data_uri += mStream.getvalue().encode('base64').replace('\n', '')

现在，您可以将 data_uri 推入图像的 src 属性中.

Now you can shove data_uri into the src attribute of an image.
