[英]How to test the CORS policy in .net core web API, if I dont have access to front end?
[英]how do i pass a datatable from a .net core 5.0 web api to an angular front end as json?
My old .net core 2 web api project used newtonsoft to serialise a datatable to json which I then passed back to a front end (angular) site as json ie using something along the lines of:
public IActionResult Countries_Get()
, query a sql server database and populate a new sql datatable ie DataTable dtCountries = clsDB.Execute_To_DataTable("selCountries", lstDBParams, Request);
.return Ok(dtCountries);
上面的代码在 .net 5.0 项目(重新开始)中不再工作,并出现System.NotSupportedException: Serialization and deserialization of 'System.Type' instances are not supported and should be avoided since they can lead to security issues. Path: $.Columns.DataType.
System.NotSupportedException: Serialization and deserialization of 'System.Type' instances are not supported and should be avoided since they can lead to security issues. Path: $.Columns.DataType.
我已经读到这是 Microsoft 的设计,因为它使用新的 System.Text.Json 命名空间是不安全的,我真的想以正确的方式前进,但经过数小时的搜索后,我离答案更近了。
有人可以建议如何做上述与原始应用程序相同的事情。
干杯
您似乎想直接返回一个 DataTable 作为结果。 事实上,这会导致安全问题。
您是否尝试过进行中间映射?
将您的 DataTable 属性放入一个新的 class 然后返回这个新的 class 作为结果。
