OneNote API创建显示红色x的图像

本文关键字：图像 红色 显示 API 创建 OneNote | 更新日期: 2023-09-27 18:16:05

尝试使用Windows Store示例将图像捕获到OneNote API被证明有点困难。

我得到一个"红色x"而不是图像。它看起来像图像源是不正确的，但我做了一些改变。

下面是我的代码:(任何帮助都会很感激)

private async void btnCreatePage_Click(object sender, RoutedEventArgs e)
        {
            await CreatePageWithImage();
        }

 private async Task CreatePageWithImage()
        {
            var client = new HttpClient();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            if (IsAuthenticated)
            {
                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authClient.Session.AccessToken);
            }
            const string imagePartName = "assets''Asthma.jpg";
            string date = GetDate();
            string simpleHtml = "<html>" +
                                "<head>" +
                                "<title>A simple page created with an image on it</title>" +
                                "<meta name='"created'" content='"" + date + "'" />" +
                                "</head>" +
                                "<body>" +
                                "<h1>This is a page with an ximage on it</h1>" +
                                "<img src='"name:" + imagePartName + "'" alt='"A beautiful logo'" width='"426'" height='"68'" />" +
                                "</body>" +
                                "</html>";
       // Create the image part - make sure it is disposed after we've sent the message in order to close the stream.
            HttpResponseMessage response;
    using (var imageContent = new StreamContent(await GetBinaryStream("assets''Asthma.jpg")))
            {
                imageContent.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");
                HttpRequestMessage createMessage = new HttpRequestMessage(HttpMethod.Post, PagesEndPoint)
                {
                    Content = new MultipartFormDataContent
                    {
                        {new StringContent(simpleHtml, System.Text.Encoding.UTF8, "text/html"), "Presentation"},
                        {imageContent, imagePartName}
                    }
                };
                // Must send the request within the using block, or the image stream will have been disposed.
                response = await client.SendAsync(createMessage);
            }
            tbResponse.Text = response.ToString();
        }

OneNote API创建显示红色x的图像

在代码中，您已将媒体类型设置为"image/jpg"。应该将其设置为"image/jpeg"。您还需要更改imagePartName以删除"'"。
