Intro#
上次更新了 asp.net core 3.0 简单的记录了一下 swagger 的使用，那个项目的 api 比较简单，都是匿名接口不涉及到认证以及 api 版本控制，最近把另外一个 api 项目升级到了 3.0，还是遇到了一些问题，这里单独写一篇文章介绍，避免踩坑。
Swagger 基本使用#
swagger 服务注册：
services.AddSwaggerGen(option =>
{
option.SwaggerDoc("sparktodo", new OpenApiInfo
{
Version = "v1",
Title = "SparkTodo API",
Description = "API for SparkTodo",
Contact = new OpenApiContact() { Name = "WeihanLi", Email = "weihanli@outlook.com" }
});
// include document file
option.IncludeXmlComments(Path.Combine(AppContext.BaseDirectory, $"{typeof(Startup).Assembly.GetName().Name}.xml"), true);
});
中间件配置：
//Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseSwagger();
//Enable middleware to serve swagger-ui (HTML, JS, CSS etc.), specifying the Swagger JSON endpoint
app.UseSwaggerUI(option =>
{
option.SwaggerEndpoint("/swagger/sparktodo/swagger.json", "sparktodo Docs");
option.RoutePrefix = string.Empty;
option.DocumentTitle = "SparkTodo API";
});
为 Swagger 添加 Bearer Token 认证#
services.AddSwaggerGen(option =>
{
// ...
// Add security definitions
option.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme()
{
Description = "Please enter into field the word 'Bearer' followed by a space and the JWT value",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
});
option.AddSecurityRequirement(new OpenApiSecurityRequirement
{
{ new OpenApiSecurityScheme
{
Reference = new OpenApiReference()
{
Id = "Bearer",
Type = ReferenceType.SecurityScheme
}
}, Array.Empty<string>() }
});
});
支持多个 ApiVersion#
services.AddApiVersioning(options =>
{
options.AssumeDefaultVersionWhenUnspecified = true;
options.DefaultApiVersion = ApiVersion.Default;
options.ReportApiVersions = true;
});
services.AddSwaggerGen(option =>
{
// ...
option.SwaggerDoc("v1", new OpenApiInfo { Version = "v1", Title = "API V1" });
option.SwaggerDoc("v2", new OpenApiInfo { Version = "v2", Title = "API V2" });
option.DocInclusionPredicate((docName, apiDesc) =>
{
var versions = apiDesc.CustomAttributes()
.OfType<ApiVersionAttribute>()
.SelectMany(attr => attr.Versions);
return versions.Any(v => $"v{v.ToString()}" == docName);
});
option.OperationFilter<RemoveVersionParameterOperationFilter>();
option.DocumentFilter<SetVersionInPathDocumentFilter>();
});
自定义 Api version 相关的 OperationFilter:
public class SetVersionInPathDocumentFilter : IDocumentFilter
{
public void Apply(OpenApiDocument swaggerDoc, DocumentFilterContext context)
{
var updatedPaths = new OpenApiPaths();
foreach (var entry in swaggerDoc.Paths)
{
updatedPaths.Add(
entry.Key.Replace("v{version}", swaggerDoc.Info.Version),
entry.Value);
}
swaggerDoc.Paths = updatedPaths;
}
}
public class RemoveVersionParameterOperationFilter : IOperationFilter
{
public void Apply(OpenApiOperation operation, OperationFilterContext context)
{
// Remove version parameter from all Operations
var versionParameter = operation.Parameters.Single(p => p.Name == "version");
operation.Parameters.Remove(versionParameter);
}
}
中间件配置：
//Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseSwagger();
//Enable middleware to serve swagger-ui (HTML, JS, CSS etc.), specifying the Swagger JSON endpoint
app.UseSwaggerUI(option =>
{
option.SwaggerEndpoint("/swagger/v2/swagger.json", "V2 Docs");
option.SwaggerEndpoint("/swagger/v1/swagger.json", "V1 Docs");
option.RoutePrefix = string.Empty;
option.DocumentTitle = "SparkTodo API";
});
最终 swagger 效果
