因此，我在Heroku上部署了Django-Rest/React应用，在那里我将静态和媒体文件放在AWS S3桶上。在推送到Heroku并访问API URL或管理URL后，一切都正常，但当我尝试访问我的React URL时，我得到了一个MIME类型的错误。
在开发者工具的网络选项卡上，我的JS和CSS文件的状态为301。
在控制台中，我得到：

Refused to apply style from 'https://app.herokuapp.com/static/css/main.9d3ee958.css/' because its MIME type 
('text/html') is not a supported stylesheet MIME type, and strict MIME checking is 
enabled.
app.herokuapp.com/:1 Refused to apply style from 'https://app.herokuapp.com/static/css/main.9d3ee958.css/' because its MIME type 
('text/html') is not a supported stylesheet MIME type, and strict MIME checking is 
enabled.
app.herokuapp.com/:1 Refused to execute script from 'https://app.herokuapp.com/static/js/main.3b833115.js/' because its MIME type 
('text/html') is not executable, and strict MIME type checking is enabled.

即使上面的URL是正确的，我确实有这些文件在我的桶。
以下是我的制作设置：

这是我的storage_backend.py代码：

from storages.backends.s3boto3 import S3Boto3Storage

class MediaStorage(S3Boto3Storage):
    location = 'media'
    file_overwrite = False

class StaticStorage(S3Boto3Storage):
    location = 'static'
    default_acl = 'public-read'

这是我的url_prod.py代码：

from django.contrib import admin
from django.urls import path, re_path, include
from django.views.generic import TemplateView
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
  path("admin/", admin.site.urls),
  path('api/', include('api.urls')),

  re_path(r'^(?P<path>.*)/$', TemplateView.as_view(template_name='index.html')),
  path('', TemplateView.as_view(template_name='index.html')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这是我的斗策：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "AllowPublicRead",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "s3:GetObject",
            "Resource": "arn:aws:s3:::bucket-name/*"
        }
    ]
}

编辑：

我检查了开发者工具中的网络选项卡，发现管理员的静态文件正在从我的was bucket中提供服务：

Request URL: 
https://bucket-name.s3.amazonaws.com/static/admin/css/base.css
Request Method: GET
Status Code: 200 OK (from disk cache)
Remote Address: 52.95.143.47:441
Referrer Policy: same-origin

但我的React视图的静态文件不是：

Request URL: 
https://app.herokuapp.com/static/css/main.9d3ee958.css
Request Method: GET
Status Code: 301 Moved Permanently
Remote Address: 54.224.34.30:441
