参数类型与参数不匹配（datetime）
参数：
{
dt:"2022-03-02 03:16:26"
}
接收：DateTime
message:"参数与参数类型不匹配"
有两种
第一种：
第一步：自定义DateTime解析类
public class DateTimeConverter : JsonConverter<DateTime>
{
public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
{
return DateTime.TryParse(reader.GetString(), out var dateTime) ? dateTime : default(DateTime);
}
public override void Write(Utf8JsonWriter writer, DateTime value, JsonSerializerOptions options)
{
writer.WriteStringValue(value.ToString("yyyy-MM-dd HH:mm:ss"));
}
}
DateTime?类型解析类
public class DateTimeNullableConvert : JsonConverter<DateTime?>
{
public override DateTime? Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
{
return DateTime.TryParse(reader.GetString(), out var dateTime) ? dateTime : default(DateTime?);
}
public override void Write(Utf8JsonWriter writer, DateTime? value, JsonSerializerOptions options)
{
writer.WriteStringValue(value?.ToString("yyyy-MM-dd HH:mm:ss"));
}
}
第二步：在startup中加入此两个类：
services.AddControllers().AddJsonOptions(config =>
{
//此设定解决JsonResult中文被编码的问题
config.JsonSerializerOptions.Encoder = JavaScriptEncoder.Create(UnicodeRanges.All);
config.JsonSerializerOptions.Converters.Add(new DateTimeConverter());
config.JsonSerializerOptions.Converters.Add(new DateTimeNullableConvert());
})
第二种比较简单
services.AddControllersWithViews()
.AddNewtonsoftJson(options=> {
options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); //序列化时key为驼峰样式 options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Local;
options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;//忽略循环引用 });
