Question

我有一个chrome扩展，可以调用本地Django服务器，如下所示：

http://127.0.0.1:8000/currentthread?threadid=2gv051

请求的标题选项卡中的以下文字：

Provisional headers are shown
Accept:*/*
Origin:chrome-extension://goacodhlgclokcokefjhmiahbgbhjbco
Referer:<SOME_DOMAIN>
User-Agent:Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36
X-DevTools-Emulate-Network-Conditions-Client-Id:A31DE079-2F0B-400A-B5BA-E3721ADB7EE6

但是，Chrome网络工具中的请求状态文字显示为(canceled)。为什么会这样，我该如何解决？我还使用django-cors-headers包添加了CORS头。

您还可以在Chrome's net-internals tool中查看错误（以及许多其他相关的有用信息）：chrome://net-internals/#events

请求从Chrome扩展程序取消到Django服务器
