Question

我有一个servicestack服务器，它使用响应过滤器向我们的服务添加数据验证消息。我的Put / Post处理程序返回一个HttpResult对象，其Response设置为我们的验证对象。然后，响应过滤器将此对象分解为将其设置为Response对象的原始html字符串。为了使其工作，我必须在“views”中创建一个String.md文件以及一个空白的html模板文件。我现在看到的问题是当我们的自定义html响应包含逗号“，”jsv fromater尝试序列化字符串并抛出异常：

我的问题是如何才能将这些回复变为jsv？或者有更好的方法来返回原始HTML？我不能让我的请求处理程序返回一个字符串，因为我需要控制响应代码和返回的标题。

您可以在HttpResult中返回HTML字符串，例如：

return new HttpResult("<html>...</html>", ContentType.Html);

对于引用，可以在以下位置找到ServiceStack的HTML Story：

除了Markdown之外，我们还添加了新的MVC Razor支持，您可以看到以下示例：
