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，启动时会出现以下错误:

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)

我已经尝试过了:

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();
            }
        });

这:

services.AddMvc(options =>
        {
            options.Filters.Add(new UserPreferencesLoaderAtrribute());

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

推荐答案

是的，我只是整夜工作，并最终弄清楚了.这是您需要做的:

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还原为"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".

然后您可以保留以下内容:

Then you can keep this:

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"

我也有很多重新部署的麻烦，但最终还是成功了.

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

祝你好运！
