我正在尝试使用Razor将对象作为JSON写入我的Asp.Net MVC View,如下所示:
<script type="text/javascript">
var potentialAttendees = @Json.Encode(Model.PotentialAttendees);
</script>
问题是在输出中JSON是编码的,我的浏览器不喜欢它。例如:
<script type="text/javascript">
var potentialAttendees = [{"Name":"Samuel Jack"},];
</script>
如何让Razor发出未编码的JSON?

你这样做:
@Html.Raw(Json.Encode(Model.PotentialAttendees))
在早于Beta 2的版本中,您可以这样做:
@(new HtmlString(Json.Encode(Model.PotentialAttendees)))

Newtonsoft JsonConvert.SerializeObject
的行为与Json.Encode
的行为不同,并且执行@ david-k-egghead建议的行为可以让您进行 XSS攻击。
将此代码放入Razor视图中,以确保使用Json.Encode
是安全的,并且可以在JavaScript上下文中使Newtonsoft变得安全,但不是没有额外的工作。
<script>
var jsonEncodePotentialAttendees = @Html.Raw(Json.Encode(
new[] { new { Name = "Samuel Jack</script><script>alert('jsonEncodePotentialAttendees failed XSS test')</script>" } }
));
alert('jsonEncodePotentialAttendees passed XSS test: ' + jsonEncodePotentialAttendees[0].Name);
</script>
<script>
var safeNewtonsoftPotentialAttendees = JSON.parse(@Html.Raw(HttpUtility.JavaScriptStringEncode(JsonConvert.SerializeObject(
new[] { new { Name = "Samuel Jack</script><script>alert('safeNewtonsoftPotentialAttendees failed XSS test')</script>" } }), addDoubleQuotes: true)));
alert('safeNewtonsoftPotentialAttendees passed XSS test: ' + safeNewtonsoftPotentialAttendees[0].Name);
</script>
<script>
var unsafeNewtonsoftPotentialAttendees = @Html.Raw(JsonConvert.SerializeObject(
new[] { new { Name = "Samuel Jack</script><script>alert('unsafeNewtonsoftPotentialAttendees failed XSS test')</script>" } }));
alert('unsafeNewtonsoftPotentialAttendees passed XSS test: ' + unsafeNewtonsoftPotentialAttendees[0].Name);
</script>

使用Newtonsoft
<script type="text/jscript">
var potentialAttendees = @(Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model.PotentialAttendees)))
</script>
