1. The rich text box submits the prompt "A potentially dangerous Request.Form value was detected from the client ()."

1.1、

1.2. The method added to the API belongs to the parameter "[ValidateInput(false)] "

[ValidateInput(false)]
        [HttpPost, Route("")]
        public JsonResult Create(Information model)
        {
            Service.Insert(model);
            return Ok("");
        }

1.3. Extend ValidateInputAttribute.cs

#region 程序集 System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
// D:\work-JFB\JFBWeb\packages\Microsoft.AspNet.Mvc.5.2.3\lib\net45\System.Web.Mvc.dll
#endregion

namespace System.Web.Mvc
{
    // 
    // Summary:
     //      Represents an attribute used to mark an action method whose input must be validated. 
    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true , AllowMultiple = false )]
     public  class ValidateInputAttribute : FilterAttribute, IAuthorizationFilter
    {
        // 
        // Summary:
         //      Initialize a new instance of the System.Web.Mvc.ValidateInputAttribute class.
        // 
        // Parameters:
         //    enableValidation:
         //      True if validation is enabled. 
        public ValidateInputAttribute( bool enableValidation );

        // 
        // Summary:
         //      Gets or sets a value indicating whether validation is enabled.
        // 
        // Return result:
         //      true if validation is enabled; otherwise, false. 
        public  bool EnableValidation { get ; }

        // 
        // Summary:
         //      Called when authorization is required.
        // 
        // Parameters:
         //    filterContext:
         //      Filter context.
        // 
        // Exception:
         //    T:System.ArgumentNullException:
         //      filterContext parameter is null. 
        public  virtual  void OnAuthorization(AuthorizationContext filterContext);
    }
}
