我遇到了以下错误:
Access to XMLHttpRequest at 'http://127.0.0.1:8000/' from origin 'http://localhost:62570' has been blocked by CORS policy: Request header field access-control-allow-origin is not allowed by Access-Control-Allow-Headers in preflight response.
我尝试添加 django-cors-headers 中间件和CORS_ALLOW_ALL_ORIGINS = True
,并在settings.py
文件中添加了ALLOWED_HOSTS = ['*']
但仍然出现相同的CORS错误。我在NestJS中也遇到了相同的问题,但在添加app.enableCors()
后问题得到解决。
这是我的settings.py
文件:
