c# - JsonSerializerSettings 和 Asp.Net Core

Question

尝试设置 JsonOutputFormatter 选项:

var jsonFormatter = (JsonOutputFormatter) options.OutputFormatters.FirstOrDefault(f => f is JsonOutputFormatter);
if (jsonFormatter != null)
{
    jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
}

或

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

但是一旦我添加这个，我就会得到:

MissingMethodException: Method not found: 'Newtonsoft.Json.JsonSerializerSettings Microsoft.AspNet.Mvc.Formatters.JsonOutputFormatter.get_SerializerSettings()'.

我使用的是标准 Microsoft.AspNet.Mvc.Formatters.Json (6.0.0-rc1-final)

编辑:通过安装 Newtonsoft.Json 6.0.6 解决了这个问题(这会降低所有其他引用)

有人知道了吗？谢谢..

.Net Core 1.0 RTM 带有开箱即用的 CamelCase 格式。这是一种行为 change来自 RC2。但是，如果您需要修改它，请尝试以下代码段:

services.AddMvc()
        .AddJsonOptions(opt =>
    {
        var resolver  = opt.SerializerSettings.ContractResolver;
        if (resolver != null)
        {
            var res = resolver as DefaultContractResolver;
            res.NamingStrategy = null;  // <<!-- this removes the camelcasing
        }
    });

对于 dotnet 核心 1.0.1:

  services
            .AddMvcCore()
            .AddJsonFormatters(o => o...);
