英文:
Keep getting a CORS error for put requests in Django from browser
问题
以下是翻译好的内容:
我在从前端应用程序(使用Fetch API)向我的Django服务器发出PUT请求时不断收到CORS错误,但在Postman中没有问题。以下是错误信息:
跨域请求被阻止:同源策略不允许读取远程资源 https://q72y0iroi2.execute-api.us-west-2.amazonaws.com/weightsheets/636。 (原因:缺少CORS头'Access-Control-Allow-Origin')。状态码:503。
不知何故,GET、POST和DELETE请求都正常工作。
我已尝试了django-cors-headers文档中建议的所有设置,但无济于事!
任何建议将不胜感激。
这是我的settings.py文件内容。
英文:
I keep getting a CORS error when I make a put request to my Django server from my frontend application (Fetch API) but not from Postman. Here is the error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://q72y0iroi2.execute-api.us-west-2.amazonaws.com/weightsheets/636. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 503.
Somehow GET, POST and DELETE requests are working fine.
I have tried all the settings suggested in the documentation for django-cors-headers but to no avail!
Any advice would be highly appreciated

只需将您的站点添加到Access-Control-Allow-Origin标头中,一切都会没问题。只需像这样执行:
Access-Control-Allow-Origin: 您域名的URL
或者
Access-Control-Allow-Origin: *
我不建议使用底部的选项,除非您知道自己在做什么。
参考链接是:CORS错误代码503
英文:
Just add your site to the Access-Control-Allow-Origin header and you'll be fine. Just do something like
Access-Control-Allow-Origin: url/of/your/domain
or
Access-Control-Allow-Origin: *
I would not recommend doing the bottom one unless you know what you are doing.
Reference would be this: CORS error code 503
