我正在使用ozeki ng短信网关。我无法将任何短信发送到任何手机。请帮助我通过网络发送短信到手机
从客户端检测到一个潜在危险的Request.Form值(textboxError =“。设置此值之后，您可以通过在Page指令或配置部分中设置validateRequest =” false“来禁用请求验证。)建议您的应用在这种情况下显式检查所有输入。有关更多信息，请参见http://go.microsoft.com/fwlink/?LinkId=153133。

最佳答案
您的问题是，其中一个字段(textboxError)的值包含XML或HTML样式的标记，默认情况下不允许使用这些标记，以避免开发人员在其应用程序中引入潜在的安全问题。
错误消息中给出了解决方案。您需要在顶部的@Page指令(在示例中省略)或web.config中添加validateRequest="false"。
请注意，如果您使用的是.net 4，则需要通过稍微更改web.config并添加以下内容，从2.0退回到验证模式。
<system.web>
<httpRuntime requestValidationMode="2.0" />
</system.web>
有关requestValidationMode的更多信息，请参见this MSDN article on requestValidationMode。
