javascript - 加载模块脚本失败：服务器以“text/plain”的非 JavaScript MIME 类型响应。对模块执行严格的 MIME 类型检查

问题描述

我在安装 django 调试工具栏以及docs时关注了这个视频。但是，我就是无法让它工作。开发工具的控制台选项卡中不断弹出 MIME 类型错误。

设置.py

from pathlib import Path
import os

BASE_DIR = Path(__file__).resolve().parent.parent

def show_toolbar(request):
    return True

    'SHOW_TOOLBAR_CALLBACK': show_toolbar
}

网址.py

from django.conf import settings
from django.contrib import admin
from django.urls import path, include

from .views import home, java_script




urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home, name='home'),
    path('.*\.js', java_script),
]


if settings.DEBUG:
    import debug_toolbar
    urlpatterns += [path('__debug__/', include(debug_toolbar.urls))]

视图.py

from django.shortcuts import render

def home(request):
    return render(request, "index.html", {})



def java_script(request):
    filename = request.path.strip("/")
    data = open(filename, "rb").read()
    return HttpResponse(data, mimetype="application/x-javascript")

base.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta Content-Type: text/html; charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <title>Document</title>
</head>
<body>
    {% block content %}
        
    {% endblock content %}
</body>
</html>

我还在HKEY_CLASSES_ROOT\.js\Content Type注册表编辑器中设置了text/javascript如下所示。

这里有一个完全相同的问题，有人要求提供更多信息，但没有提供任何信息，我也无法添加评论。因此，一个全新的问题。

编辑：工具栏出现在微软边缘，WTF !!!
