Django的。如何发送'假'MIME类型图像以避免警告

I send a quick message to my server by setting the message as an image src. (It's faster than Ajax and I don't need a response).

我通过将消息设置为图像src来向我的服务器发送快速消息。（它比Ajax更快，我不需要响应）。

var img = new Image();
var msg= "something happened";
img.src = my_domain_url +'?' + msg;

Server side I return something to avoid an error:

服务器端我返回一些东西以避免错误：

return HttpResponse("ok")

However, I get a warning:

但是，我得到一个警告：

"Resource interpreted as Image but transferred with MIME type text/html:"

“资源解释为图像，但使用MIME类型text / html传输：”

How can I avoid that? I guess I need to send an image type, but do I need to send an actual image?

我怎么能避免这种情况？我想我需要发送图像类型，但是我需要发送实际图像吗？

Well of course you're going to get that message, you're telling JavaScript to get an Image at some URL but instead text is being returned. You could just do

那么你当然会得到那条消息，你告诉JavaScript在某个URL上获取一个图像，但是正在返回文本。你可以这样做

HttpResponse("ok", content_type="image/jpeg")

Though i'm not sure what the implications are of returning the string "ok" to a var image in JavaScript.

虽然我不确定将字符串“ok”返回到JavaScript中的var图像有什么影响。

see the documentation on the HttpResponse

请参阅HttpResponse上的文档
