asp.net core 6中跨域问题-Toy模板网

这篇具有很好参考价值的文章主要介绍了asp.net core 6中跨域问题。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

1.在使用 .net 6 开发WEBAPI程序时，出现跨域问题。原来的写法不能用了。用下面的写法解决问题

builder.Services.AddCors(options =>
{
   options.AddPolicy("any", builder =>
   {
       builder.SetIsOriginAllowed(_ => true).AllowAnyMethod().AllowAnyHeader().AllowCredentials();
   });
});

app.UseCors("any");文章来源地址https://www.toymoban.com/news/detail-601104.html
