我有一个运行ASP.net项目的Azure Web应用程序服务。客户端是JavaScript，服务器端是C＃。

我们一直在JSON上看到错误。服务器响应响应失败的Parse调用失败：

SyntaxError: Unexpected token S in JSON at position 0
at JSON.parse (<anonymous>)

将对控制器上的/ SubmitPromoCode进行调用。这是我在KUDU控制台的eventLogs上找到的：

有人知道为什么会出现此问题并通过重新启动应用程序服务来解决此问题吗？

答案 0 :(得分：0)

在本地删除我的项目上的MVC依赖项并将依赖项设置为该项目构建的DLLS时，我遇到了问题。这使我可以在MVC调用中进行调试，这非常方便，但是以这种状态发布项目是导致此问题的原因。

重建项目，以便将依赖项设置为标准MVC安装随附的DLL即可解决此问题。
