“五一”期间用了一下Swagger,碰到了以下问题:
现将解决办法记下留存。
一、在Docker中显示OpenApiInfo的中文内容
builder.Services.AddSwaggerGen(options => { options.SwaggerDoc("v1", new OpenApiInfo { Version = "v1", Title = "xxx Api调用说明", Description = "巴拉巴拉的一堆描述", License = new OpenApiLicense { Name = "Api调用须知", Url = new Uri("http://xxx.com/readmi.html") } }); });
以上设置的效果
然而发布到Docker以后,中文乱码了(似乎在Program.cs里面输入的中文都会乱码)。我的解决的办法是:
builder.Services.AddSwaggerGen(ProgramHelper.SwaggerSetup);
using Microsoft.OpenApi.Models; using Swashbuckle.AspNetCore.SwaggerGen; namespace SwaggerDemo; public static class ProgramHelper { public static void SwaggerSetup(SwaggerGenOptions options) { options.SwaggerDoc("v1", new OpenApiInfo { Version = "v1", Title = "xxx Api调用说明", Description = "巴拉巴拉的一堆描述", License = new OpenApiLicense { Name = "Api调用须知", Url = new Uri("http://xxx.com/readmi.html") } }); } }
问题解决,但有点脱裤子放屁,不知道有没有不需要脱裤子的方法。
二、显示xml注释
这个微软文档说的很清楚,这里记一下网址备查。
三、如何显示Header
办法如下:
public class SwaggerHeaderAttribute : Attribute { } public class SwaggerOperationFilter : IOperationFilter { public void Apply(OpenApiOperation operation, OperationFilterContext context) { if (context.ApiDescription.CustomAttributes().Any(ii => ii.GetType() == typeof(SwaggerHeaderAttribute)) || context.ApiDescription.ActionDescriptor.EndpointMetadata.Any(ii => ii.GetType() == typeof(SwaggerHeaderAttribute))) { if (operation.Parameters == null) operation.Parameters = new List<OpenApiParameter>(); operation.Parameters.Add(new OpenApiParameter { Name = "Sign", In = ParameterLocation.Header, Description = "我的签名是这个生成的,巴拉巴拉巴拉", Required = true }); } } }
然后在SwaggerSetup里面添加一行
options.OperationFilter<SwaggerOperationFilter>();
在ApiController或者Action前面添加一行[SwaggerHeader]
四、隐藏ApiController、Action、类或者属性,显示枚举
想把1、2隐藏起来,把
public enum ECode { 成功, [Description("时间戳错误")] Timestamp, [Description("签名错误")] Sign }
显示成3的样子,办法如下:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class | AttributeTargets.Property | AttributeTargets.Enum | AttributeTargets.Field)] public partial class SwaggerIgnoreAttribute : Attribute { } public class SwaggerSchemaFilter : ISchemaFilter { public void Apply(OpenApiSchema schema, SchemaFilterContext context) { #region 给设置了SwaggerIgnoreAttribute特性的类作个标记,以便在DocumentFilter里面移除整个架构 if (context.Type.GetCustomAttribute<SwaggerIgnoreAttribute>() != null) { schema.Title = "Remove"; } #endregion else { if (context.Type.IsEnum) { #region 设置枚举的描述 List<string> titleItems = new List<string>(); foreach (var e in Enum.GetValues(context.Type)) { if (context.Type.GetField(e.ToString()).GetCustomAttribute<SwaggerIgnoreAttribute>() == null) { titleItems.Add($"{(int)e}:{context.Type.GetField(e.ToString()).GetCustomAttribute<DescriptionAttribute>()?.Description ?? e}"); } } schema.Description = string.Join(";", titleItems); #endregion } else { #region 移除设置了SwaggerIgnoreAttribute特性的属性 foreach (var propertyName in context.Type.GetProperties().Where(ii => ii.GetCustomAttribute<SwaggerIgnoreAttribute>() != null).Select(ii => ii.Name)) schema.Properties.Remove(propertyName); #region } } } } public class SwaggerDocFilter : IDocumentFilter { public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context) { //移除在SchemaFilter作了标记的架构 foreach (var key in swaggerDoc.Components.Schemas.Where(ii => ii.Value.Title == "Remove")) swaggerDoc.Components.Schemas.Remove(key); #region 移除设置了SwaggerIgnoreAttribute特性的ApiController var ignoreApis = context.ApiDescriptions.Where(wh => wh.ActionDescriptor.EndpointMetadata.Any(any => any is SwaggerIgnoreAttribute)); if (ignoreApis != null) { foreach (var ignoreApi in ignoreApis) { swaggerDoc.Paths.Remove("/" + ignoreApi.RelativePath); } } #endregion } }
照例需要在在SwaggerSetup里面添加两行
options.SchemaFilter<SwaggerSchemaFilter>();
options.DocumentFilter<SwaggerDocFilter>();
然后给隐藏的内容添加[SwaggerIgnore]
如此,大致达到了我的目的,但存两点不爽:
