This work out for me :
in javascript :
Axios({
method: 'post',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
url: 'https://localhost:44346/Order/Order/GiveOrder',
data: order
}).then(function (response) {
console.log(response.data);
});
and in the backend (.net core) : in startup:
#region Allow-Orgin
services.AddCors(c =>
{
c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin());
});
#endregion
and in controller before action
[EnableCors("AllowOrigin")]
