处理来自Microsoft Graph的照片响应 [英] Handling photo response from Microsoft Graph

问题描述

我无法弄清楚此调用实际返回的内容以及如何将其显示为HTML中的img标记.当我在联机Microsoft Graph Explorer测试环境中使用相同的URI时，将获得预期的图像.

I can't figure out what actually is returned by this call and how I can display it in HTML as an img tag. When I use the same URI using the online Microsoft Graph Explorer test environment I get the image as intended.

var requestUri =
    "https://graph.microsoft.com/v1.0/barfoo.onmicrosoft.com/users/xxxxx-xxxxxx-xxxxx/photo/$value";

var request =
    new HttpRequestMessage(HttpMethod.Get, requestUri);

var accessToken =
    await _authenticationHelper.GetAccessTokenAsync();

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

var response = await client.SendAsync(request);

推荐答案

HttpClient可以为您提供Stream的响应.

HttpClient can give you the response as a Stream.

在ASP.NET Core中，我这样做的是:

In ASP.NET Core, I've done this with:

[HttpGet]
public async Task<IActionResult> ProfilePhoto()
{
    //removed all the code which you already have
    HttpResponseMessage res = await client.SendAsync(request);

    return File(await res.Content.ReadAsStreamAsync(), "image/jpeg");
}

经典" ASP.NET MVC应该完全相同，您至少应将IActionResult替换为ActionResult.

"Classic" ASP.NET MVC should be pretty identical, you would replace IActionResult with ActionResult at least.

然后您可以将其链接到图像标签，例如:

You can then link this to an image tag like:

<img src="/Home/ProfilePhoto"/>
