core MVC 默认大小写不敏感

对于.Net Core 3.1及以上版本, 默认使用json序列化/反序列化时对大小写不敏感. 设置大小写敏感, 在Startup.cs中添加:

            services.AddControllersWithViews().AddNewtonsoftJson(opt =>
            {
                // lazy mode json Serializer
                opt.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
                // donot up case the first letter
                opt.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver();
            });

一些简单配置如下.

public void ConfigureServices(IServiceCollection services)
{
     services.AddJsonOptions(options =>
            {
                //格式化日期时间格式
                options.JsonSerializerOptions.Converters.Add(new DatetimeJsonConverter());
                //数据格式首字母小写
                //options.JsonSerializerOptions.PropertyNamingPolicy =JsonNamingPolicy.CamelCase;
                //数据格式原样输出
                options.JsonSerializerOptions.PropertyNamingPolicy = null;
                //取消Unicode编码
                options.JsonSerializerOptions.Encoder = JavaScriptEncoder.Create(UnicodeRanges.All);
                //忽略空值
                options.JsonSerializerOptions.IgnoreNullValues = true;
                //允许额外符号
                options.JsonSerializerOptions.AllowTrailingCommas = true;
                //反序列化过程中属性名称是否使用不区分大小写的比较
                options.JsonSerializerOptions.PropertyNameCaseInsensitive = false;
            });
}
