我有一堂课：
class Test {
public IPAddress Ip {get; set; }
}
默认情况下，http://localhost:1234/swaggerNswag.AspNetCore上的 Nswag (包)将其序列化，在预览“示例”输出中：
[
"Ip": {
"AddressFamily": 0,
"ScopeId": 0,
"IsIPv6Multicast": true,
"IsIPv6LinkLocal": true,
"IsIPv6SiteLocal": true,
"IsIPv6Teredo": true,
"IsIPv4MappedToIPv6": true,
"Address": 0
}
]
我想对其进行自定义，以便它仅将 Ip 字段序列化为 astring而没有IPAddress.
为此，我创建了自己的JsonConverter：
public class IPAddressConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(IPAddress));
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
writer.WriteValue(value.ToString());
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
return IPAddress.Parse((string)reader.Value);
}
}
并验证它可以与 JSON.Net 一起使用。
var settings = new JsonSerializerSettings() { Converters = { new IPAddressConverter() } };
JsonConvert.SerializeObject(IPAddress.Parse("123.123.123.123"), settings);
JsonConvert.DeserializeObject<IPAddress>("123.123.123.123", settings);
现在我想把它插入到 NSwag 中。我在 ASP.Net 的 Startup.cs 中修改了 NSwag 设置：
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMvc();
var swaggerSettings = new SwaggerUi3Settings()
{
ContractResolver = new CustomSwaggerContractResolver(),
DefaultPropertyNameHandling = NJsonSchema.PropertyNameHandling.Default /* If this is not set to default it raises an exception when a ContractResolver is set and then swagger page does not load at all */
};
app.UseSwaggerUi3(typeof(Startup).Assembly, swaggerSettings);
}
#
public class CustomSwaggerContractResolver : DefaultContractResolver
{
protected override JsonContract CreateContract(Type objectType)
{
JsonContract contract = base.CreateContract(objectType);
if (objectType == typeof(IPAddress))
{
contract.Converter = new IPAddressConverter();
}
return contract;
}
}
不幸的是，当我浏览到http://localhost:1234/swagger以查看我的类的 Json“示例”输出时Test，它仍然包括所有属性，IPAddress而不是Ip字段被序列化为简单的string.
当我调试时，我可以看到里面的代码CustomSwaggerContractResolver被调用，并且转换器被分配，但它IPAddressConverter本身从未被调用。
有什么我想念的吗？
谢谢你。
