使用graph API上载到MS团队的文档已损坏

microsoft-teams microsoft-graph-api c#

我正在尝试使用Microsoft Graph(测试版)将文档上载到Microsoft团队,但成功上载后文档会损坏。

使用Graph,我首先创建一个组,基于该组创建一个团队,添加一些团队成员,最后将文档上传到默认通道。

除了上传的文档被破坏,Office Online editor无法打开之外,其他一切正常。但是,我们可以下载该文件并在更正该文件后在Microsoft Word中打开。

下面是我用于文档上传的代码->

FileInfo fileInfo = 
    new FileInfo(@"F:\Projects\TestProjects\MSTeamsSample\MSTeamsSample\Files\Test File.docx");

var bytes = System.IO.File.ReadAllBytes(fileInfo.FullName);
var endpoint = $"https://graph.microsoft.com/beta/groups/{groupId}/drive/items/root:/General/{fileInfo.Name}:/content";

var fileContent = new ByteArrayContent(bytes);
fileContent.Headers.ContentType = 
    MediaTypeHeaderValue.Parse("application/octet-stream");

var requestContent = new MultipartFormDataContent();
requestContent.Add(fileContent, "File", fileInfo.Name);

var request = new HttpRequestMessage(HttpMethod.Put, endpoint);
request.Headers.Authorization = 
    new AuthenticationHeaderValue("Bearer", "<Access Token>");
request.Content = requestContent;
var client = new HttpClient();
var response = client.SendAsync(request).Result;

我尝试将内容类型更改为 application/vnd.openxmlformats-officedocument.wordprocessingml.document 但运气不好。我不明白这里怎么了。基于此,代码非常简单 documentation .任何帮助都将不胜感激。

请试试这个:

        var filePath = @"F:\Projects\TestProjects\MSTeamsSample\MSTeamsSample\Files\Test File.docx";
        var fileName = Path.GetFileName(filePath);
        var fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
        var endpoint = $"https://graph.microsoft.com/beta/groups/{groupId}/drive/items/root:/General/{fileName}:/content";

        using (var client = new HttpClient())
        {
            using (var content = new StreamContent(fileStream))
            {
                content.Headers.Add("Content-Type", MimeMapping.GetMimeMapping(fileName));

                // Construct the PUT message towards the webservice
                using (var request = new HttpRequestMessage(HttpMethod.Put, endpoint))
                {
                    request.Content = content;

                    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", tokenResponse.Token);

                    // Request the response from the webservice
                    using (var response = await client.SendAsync(request))
                    {
                        // Check the response.
                    }
                }
            }
        }

我可以在微软团队编辑器中看到Word文档。
