找不到方法:'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.MvcJsonOptions.get_SerializerSettings()' [英] Method not found: 'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.MvcJsonOptions.get_SerializerSettings()'

问题描述

我的项目在本地运行良好，但是当我使用 Web 应用程序在 Azure 上部署时，启动时出现以下错误:

Locally my project runs fine but when I deploy on Azure using a web app, I get the following error when it starts:

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)

MissingMethodException: Method not found: 'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.Formatters.JsonOutputFormatter.get_SerializerSettings()'. SmartAdmin.Startup.<>c.b__13_7(MvcOptions options)

我试过了:

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();
        });

推荐答案

是的，我只是工作了一夜，最终还是弄明白了.以下是您需要做的:

Yes, I just worked all night and did eventually figured it out. Here is what you need to do:

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".

Make sure you install: -Microsoft.AspNet.Mvc.Formatters.Json version "6.0.0-rc1-final" and -Revert Netonsoft.Json to "6.0.6".

那么你可以保留这个:

services.AddMvc().AddJsonOptions(options =>
    {
        options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    });

project.json:

project.json:

"Microsoft.AspNet.Mvc.Formatters.Json": "6.0.0-rc1-final",Newtonsoft.Json":6.0.6"

"Microsoft.AspNet.Mvc.Formatters.Json": "6.0.0-rc1-final", "Newtonsoft.Json": "6.0.6"

我在重新部署时也遇到了很多麻烦，但最终这成功了.

I had a bunch of trouble redeploying too but eventually this worked.

祝你好运！
