Microsoft Graph API更新其他用户的照片？

Question

using (HttpClient client = new HttpClient())
{
    client.BaseAddress = new Uri("https://graph.microsoft.com/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("image/jpeg"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", oauthToken);

    // HTTP GET                
    HttpResponseMessage response = await client.PatchAsync($"v1.0/users/{emailAddress}/photo/$value", byteContent);
    if (!response.IsSuccessStatusCode)
    {
        throw new Exception("Error!");
    }
}

403禁止

是不可能使用Graph API做到这一点，还是我在某个地方缺少了一个权限？

SCP值为：calendars.read calendars.read write contacts.read contacts.read write directory.accessasuser.all directory.read.all directory.readwrite.all email exchange.manage files.read files.readwrite.selected files.readwrite.readwrite.selected full_access_asuser group.read.all group.readwrite.readwrite.selected files.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.readwrite.Basic.All用户.ReadWrite用户.ReadWrite.All

首先，您应该看看在//Build 2016期间发布的新的Microsoft Graph SDK这里是Microsoft Graph SDK的Github：https://Github.com/microsoftgraph
这里是我使用它创建的完整示例：https://Github.com/mimetis/nextMeetingsforGraphSample

对于您的问题，下面是我编写的两个方法，它们对我起作用：我假设，您有一个方法可以获得有效的访问令牌。

using (HttpClient client = new HttpClient())
{
    var authResult = await AuthenticationHelper.Current.GetAccessTokenAsync();
    if (authResult.Status != AuthenticationStatus.Success)
        return;

    client.DefaultRequestHeaders.Add("Authorization", "Bearer " + authResult.AccessToken);

    Uri userPhotoEndpoint = new Uri(AuthenticationHelper.GraphEndpointId + "users/" + userIdentifier + "/Photo/$value");
    StreamContent content = new StreamContent(image);
    content.Headers.Add("Content-Type", "application/octet-stream");

    using (HttpResponseMessage response = await client.PutAsync(userPhotoEndpoint, content))
    {
        response.EnsureSuccessStatusCode();
    }
}

如果您使用Microsoft Graph SDK，它将非常简单：）

GraphServiceClient graphService = new GraphServiceClient(AuthenticationHelper.Current);
var photoStream = await graphService.Users[userIdentifier].Photo.Content.Request().PutAsync(image); //users/{1}/photo/$value
