با سلام بله من تمام اپ های که دارم کار میکنم از پایه وب اپلیکیشن هستن در این پروژه از  بک اند فایل جنگو شما هستش  رو ست کردم  و برای  درخواستهای که سمت سرور میره فایل هدر سمت فلاتر   رو با کد زیر ست کردم :

"Access-Control-Allow-Origin": "*", // Required for CORS support to work
"Access-Control-Allow-Credentials": true.toString(), // Required for cookies, authorization headers with HTTPS
"Access-Control-Allow-Headers": "Origin,Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token,locale",
"Access-Control-Allow-Methods": "POST, OPTIONS"

ولی بک اند رو نمی دونم چطور ست کنم هر کاری بگین انجام دادم الان سه تا پروژه من سر همین خطا خوابیده .ممنون میشم راهنمایی کنید.
