Startup
全局配置Json序列化处理
1.忽略循环引用
2.long转string
//全局配置Json序列化处理
services.AddJsonOptions(options =>
{
//忽略循环引用
options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
options.SerializerSettings.Converters.Add(new Common.LongConvert());//Long类型转换
//在这里日期类格式化处理是不起作用的
//不返回值为NULL的属性,甚用啊,数据要很严谨
//options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
});
数据处理
1.时间格式
2.string null转空
Startup
services.PostConfigure<MvcJsonOptions>(options =>
{
options.SerializerSettings.ContractResolver = new CustomContractResolver();
});

json序列化小驼峰格式
属性名首字母为小写
var setting = new JsonSerializerSettings
{
ContractResolver = new Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver()
};
var json = JsonConvert.SerializeObject(resp, Formatting.None, setting);
