我正在使用以下代码来配置ASP.NET Core 3.1控制器方法,以上载包含2个部分的多部分请求,一个部分名为“元数据”以包含JSON模型,另一部分名为“ file”以包含实际文件二进制Swagger UI似乎可以正确呈现,但是在调用该操作时,它从未为我的元数据部分发送“内容类型”。
调试我的控制器方法时,文件二进制文件的部分很好,并包含“ content-type”标头,但是当我检查元数据部分的标头时,“ content-type”标头丢失了。对于元数据部分,我收到的唯一标头是“ content-disposition”。
我确实确认swagger.json正确显示“ application / json”作为元数据部分的内容类型。
当前我正在使用Swashbuckle.AspNetCore v5.0.0-rc4
我在操作过滤器中缺少任何东西吗?
public class FileUploadOperationFilter : IOperationFilter
{
public virtual void Apply(OpenApiOperation operation, OperationFilterContext context)
{
context?.MethodInfo?.GetCustomAttribute<FileUploadOperationAttribute>()?.Apply(operation, context);
}
}
[AttributeUsage(AttributeTargets.Method)]
public class FileUploadOperationAttribute : Attribute
{
public Type MetadataType { get; }
public string MetadataPropertyName { get; set; } = "metadata";
public string FilePropertyName { get; set; } = "file";
public FileUploadOperationAttribute(Type metadataType)
{
MetadataType = metadataType;
}
public virtual void Apply(OpenApiOperation operation, OperationFilterContext context)
{
if (operation == null || context == null)
return;
var metadataSchema = context.SchemaGenerator.GenerateSchema(
MetadataType,
context.SchemaRepository);
operation.RequestBody = new OpenApiRequestBody
{
Content = new Dictionary<string, OpenApiMediaType>
{
["multipart/form-data"] = new OpenApiMediaType
{
Schema = new OpenApiSchema
{
Type = "object",
Properties = new Dictionary<string, OpenApiSchema>
{
[MetadataPropertyName] = metadataSchema,
[FilePropertyName] = new OpenApiSchema
{
Type = "string",
Format = "binary",
},
},
},
Encoding = new Dictionary<string, OpenApiEncoding>
{
[MetadataPropertyName] = new OpenApiEncoding
{
ContentType = "application/json",
},
},
}
},
};
}
}
[HttpPut("{fileName}/versions/{version}/content")]
[FileUploadOperation(typeof(SubmitFileRequest))]
[ProducesResponseType(StatusCodes.Status204NoContent)]
[ProducesResponseType(typeof(GenericActionResponse), StatusCodes.Status404NotFound)]
public async Task<IActionResult> SubmitFileVersionContentAsync([FromRoute] string fileName, [FromRoute] string version, CancellationToken cancellationToken)
{
// code omitted for brevity...
}
public class SubmitFileRequest
{
[Required]
public DateTime CreationTimeUtc { get; set; }
[Required]
public DateTime LastWriteTimeUtc { get; set; }
[Required]
public string InstallMethod { get; set; }
}

这是Swagger UI的问题–当前(截至2019年12月),它没有向Content-Type
请求中的JSON数据添加multipart/*
头。在此跟踪该问题:
