我尝试使用NPM / Webpack / Vue.js创建ASP.NET Core MVC应用程序。我正在学习本教程:https://marczak.io/posts/netcore-vuejs/
启动项目时,我得到以下异常:
An exception of type 'System.AggregateException' occurred in System.Private.CoreLib.dll but was not handled in user code: 'One or more errors occurred.'
Inner exceptions found, see $exception in variables window for more details.
Innermost exception Newtonsoft.Json.JsonReaderException : Unexpected character encountered while parsing value: <. Path '', line 0, position 0.
at Newtonsoft.Json.JsonTextReader.ParseValue()
at Newtonsoft.Json.JsonTextReader.Read()
at Newtonsoft.Json.JsonReader.ReadForType(JsonContract contract, Boolean hasConverter)
at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.Deserialize(JsonReader reader, Type objectType, Boolean checkAdditionalContent)
异常发生在Configure方法的Startup.cs中:
app.UseWebpackDevMiddleware(new WebpackDevMiddlewareOptions
{
HotModuleReplacement = true
});
好像有些JSON文件格式错误了?!但是哪一个。我是NPM和Webpack的新手。
如果您需要更多信息,请与我们联系。
发现这个dotnet问题:https://github.com/dotnet/core/issues/1726
我在代理后面,需要停用它(我不能)或在Program.cs的Main()方法中添加此行之前的其他内容:
AppContext.SetSwitch("System.Net.Http.UseSocketsHttpHandler", false);
