本地我的项目运行正常,但当我使用Web应用程序在Azure上部署时,我在启动时收到以下错误:
MissingMethodException:找不到方法:’Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.Formatters.JsonOutputFormatter.get_SerializerSettings()’.
SmartAdmin.Startup.<> c.b__13_7(MvcOptions选项)
我试过这个:
services.AddMvc(options => { options.Filters.Add(new UserPreferencesLoaderAtrribute()); var jsonFormatter = (JsonOutputFormatter)options.OutputFormatters.FirstOrDefault(f => f is JsonOutputFormatter); if (jsonFormatter != null) { jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } });
还有这个:
services.AddMvc(options => { options.Filters.Add(new UserPreferencesLoaderAtrribute()); }).AddJsonOptions(options => { options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); });
是的,我刚刚工作了一整夜,并最终弄明白了.这是你需要做的:
确保安装:
-Microsoft.AspNet.Mvc.Formatters.Json版本“6.0.0-rc1-final”
和
– 将Netonsoft.Json恢复为“6.0.6”.
然后你可以保持这个:
services.AddMvc().AddJsonOptions(options => { options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); });
project.json:
“Microsoft.AspNet.Mvc.Formatters.Json”:“6.0.0-rc1-final”,
“Newtonsoft.Json”:“6.0.6”
我在重新部署时遇到了一些麻烦,但最终还是有效.
祝好运!
