Swagger UI failing to execute multiple file upload (open api 3.01)
I have a .aspnet core 3.1 project that implements swagger UI (5.00). One of the API methods posts multiple images, [HttpPost("images", Name = "PostImages")] public async Task<IActionResult> Images([FromForm] IEnumerable<IFormFile> files) { I am implementing an IOperationFilter to rebake the schema. if (operation.OperationId != "PostImages") { return; } var properties = new Dictionary<string, OpenApiSchema>(); var openApiSchema = new OpenApiSchema { Type = "array", Items = new OpenApiSchema { Type = "string", Format = "binary", Description = "Multiple File Upload" } }; properties.Add("files", openApiSchema); operation.RequestBody.Content["multipart/form-data"].Schema.Properties = properties; Where the json looks like this, "/api/Upload/images": { "post": { "tags": [ "Upload" ], "operationId": "PostImages", "requestBody": { "content": { "multipart/form-data": { "schema": { "type": "object", "properties": { "files": { "type": "array", "items": { "type": "string", "description": "Multiple File Upload", "format": "binary" } } } }, "encoding": { "files": { "contentType": "image/png", "style": "form" } } } } }, Seems like all of this is correct but when breaking in the method I get no files. My dev tools show the request body as, files: [object File],[object File] Throw me a bone someone. This is driving me crazy. Thank you5KViews0likes1Comment
