是否有一种方法显示所有枚举作为他们的字符串值在swagger而不是他们的int值?
我希望能够提交POST动作，并根据它们的字符串值放置枚举，而不必每次都查看enum。
我尝试了DescribeAllEnumsAsStrings，但服务器然后接收字符串而不是enum值，这不是我们要寻找的。
有人解决了吗?
编辑:
public class Letter
{
[Required]
public string Content {get; set;}
[Required]
[EnumDataType(typeof(Priority))]
public Priority Priority {get; set;}
}
public class LettersController : ApiController
{
[HttpPost]
public IHttpActionResult SendLetter(Letter letter)
{
// Validation not passing when using DescribeEnumsAsStrings
if (!ModelState.IsValid)
return BadRequest("Not valid")
..
}
// In the documentation for this request I want to see the string values of the enum before submitting: Low, Medium, High. Instead of 0, 1, 2
[HttpGet]
public IHttpActionResult GetByPriority (Priority priority)
{
}
}
public enum Priority
{
Low,
Medium,
High
}
为了生成有名称和值的枚举，可以使用此解决方案。
先决条件:
你正在使用NSwag或Openapi-generator来生成API客户端
你有一个旧的Web Api项目(pre . net Core)并使用Swashbuckle。WebApi包
SchemaFilter登记:
GlobalConfiguration.Configuration
.EnableSwagger("/swagger", c =>
{
c.SchemaFilter<EnumSchemaFilter>();
});
EnumSchemaFilter:
public class EnumSchemaFilter : ISchemaFilter
{
public void Apply(Schema schema, SchemaRegistry schemaRegistry, Type type)
{
var enumProperties = schema.properties?.Where(p => p.Value.@enum != null);
if(enumProperties != null)
{
foreach (var property in enumProperties)
{
var array = Enum.GetNames(type.GetProperty(property.Key).PropertyType).ToArray();
property.Value.vendorExtensions.Add("x-enumNames", array); // NSwag
property.Value.vendorExtensions.Add("x-enum-varnames", array); // Openapi-generator
}
}
}
}
在。net core 3.1和swagger 5.0.0中:
using System.Linq;
using Microsoft.OpenApi.Any;
using Microsoft.OpenApi.Models;
using Swashbuckle.AspNetCore.SwaggerGen;
namespace WebFramework.Swagger
{
public class EnumSchemaFilter : ISchemaFilter
{
public void Apply(OpenApiSchema schema, SchemaFilterContext context)
{
if (context.Type.IsEnum)
{
var enumValues = schema.Enum.ToArray();
var i = 0;
schema.Enum.Clear();
foreach (var n in Enum.GetNames(context.Type).ToList())
{
schema.Enum.Add(new OpenApiString(n + $" = {((OpenApiPrimitive<int>)enumValues[i]).Value}"));
i++;
}
}
}
}
}
在Startup.cs中:
services.AddSwaggerGen(options =>
{
#region EnumDesc
options.SchemaFilter<EnumSchemaFilter>();
#endregion
});
ASP。NET Core 3与Microsoft JSON库(System.Text.Json)
在Startup.cs / ConfigureServices ():
services
.AddControllersWithViews(...) // or AddControllers() in a Web API
.AddJsonOptions(options =>
options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter()));
ASP。NET Core 3和Json。NET (Newtonsoft.Json)库
安装Swashbuckle.AspNetCore.Newtonsoft包。
在Startup.cs / ConfigureServices ():
services
.AddControllersWithViews(...)
.AddNewtonsoftJson(options =>
options.SerializerSettings.Converters.Add(new StringEnumConverter()));
// order is vital, this *must* be called *after* AddNewtonsoftJson()
services.AddSwaggerGenNewtonsoftSupport();
ASP。NET Core 2
在Startup.cs / ConfigureServices ():
services
.AddMvc(...)
.AddJsonOptions(options =>
options.SerializerSettings.Converters.Add(new StringEnumConverter()));
Pre-ASP。网络核心
httpConfiguration
.EnableSwagger(c =>
{
c.DescribeAllEnumsAsStrings();
});
