Umbraco Media Services创建媒体

本文关键字：媒体 创建 Services Media Umbraco | 更新日期: 2023-09-27 18:12:02

我需要帮助，我目前正在开发一个Umbraco api，它将从第三方网站以编程方式创建媒体。

我使用下面的代码创建媒体

    public HttpResponseMessage CreateMedia()
    {
        var mediaService = Services.MediaService;
        using (WebClient client = new WebClient())
        {
            Stream s = client.OpenRead("http://karl.media.local/Uploads/ef093845-41dd-4620-        b220-1b346a5f9b2e.jpg");
            using (MemoryStream ms = new MemoryStream())
            {
                s.CopyTo(ms);
                var mediaImage = mediaService.CreateMedia("test4", 1152, "Image");
                mediaImage.SetValue("umbracoFile", "test4", ms);
                mediaService.Save(mediaImage);
            }
        }
        var response = Request.CreateResponse(HttpStatusCode.OK);
        response.Content = new StringContent("ExternalMediaCreate", Encoding.UTF8, "application/json");
        return response;
    }
}

我在这行mediaImage上得到以下错误。SetValue("umbracoFile"， "test4"， ms);:

<Error>
    <Message>An error has occurred.</Message>
    <ExceptionMessage>
        Length cannot be less than zero. Parameter name: length
    </ExceptionMessage> 
</Error>

任何帮助都将不胜感激，

Thanks in advance

已修复。

我需要将文件加载到一个文件流中，这样我才能访问文件名。

public HttpResponseMessage CreateMedia()
        {
            var mediaService = Services.MediaService;
            var request = WebRequest.Create("http://karl.media.local/Uploads/ef093845-41dd-4620-b220-1b346a5f9b2e.jpg");
            var webResponse = request.GetResponse();
            var responseStream = webResponse.GetResponseStream();
            if (responseStream != null)
            {
                var originalImage = new Bitmap(responseStream);
                var path = HttpContext.Current.Server.MapPath("~/_tmp/ef093845-41dd-4620-b220-1b346a5f9b2e.jpg");

                originalImage.Save(path, ImageFormat.Jpeg);

                FileStream fileStream = new FileStream(path, FileMode.Open);
                var test = fileStream.Name;

                var mediaImage = mediaService.CreateMedia("test4", 1152, "Image");
                mediaImage.SetValue("umbracoFile", test, fileStream);
                mediaService.Save(mediaImage);
                responseStream.Dispose();
                webResponse.Dispose();
                originalImage.Dispose();
            }

            var response = Request.CreateResponse(HttpStatusCode.OK);
            response.Content = new StringContent("ExternalMediaCreate", Encoding.UTF8, "application/json");
            return response;
        }
