无法使用 ms graph 设置个人资料照片

Question

I tried the following:

filePath = sourcePath + "ash.jpg";

byte[] fileContent = FileUtils.readFileToByteArray(new File(filePath));
String encodedString = Base64.getEncoder().encodeToString(fileContent);

imagePayload = HttpRequest.BodyPublishers.ofString(encodedString)

def url='https://graph.microsoft.com/v1.0/users/<myuser>/photo/$value';

HttpClient httpClient = HttpClient.newBuilder()
                        .version(HttpClient.Version.HTTP_2)
                        .build();

HttpRequest request = HttpRequest.newBuilder()
                      .uri(URI.create(url))
                      .method("PUT",imagePayload)
                      .header("Content-Type", "image/jpeg")
                      .header("Authorization", "Bearer " + token)
                      .build();

the return keeps telling me:

An internal server error occurred. The operation failed., The file you chose isn't an image. Please choose a different file.

I guess that the payload is wrong, but what does he expect exactly? the MS Graph documentation states that it should the binary represetation of the jpeg image

with the following:

filePath = sourcePath + "ash.jpg";

file = new File(filePath);

BufferedImage image = ImageIO.read(file);

ByteArrayOutputStream b = new ByteArrayOutputStream();
ImageIO.write(image, "jpg", b);

byte[] jpgByteArray = b.toByteArray();

StringBuilder sb = new StringBuilder();
for (byte by : jpgByteArray)
    sb.append(Integer.toBinaryString(by & 0xFF));

imagePayloadAsString = sb.toString();

imagePayload = HttpRequest.BodyPublishers.ofString(imagePayloadAsString)

I get the binary string with Os and 1s but the webservice still says that my file is not an image. I must confess that I'm confused

Answer 1

This endpoint takes the raw image as input, not a base64 encoded version. Check the documentation . In the request body, include the binary data of the photo in the request body.

I see that you're using HTTPClient. I would do like the following:

Code snippet:

 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(); } }

Answer 2

I finally got it. what the ms graph service awaits is just the file itself (with the header image/jpeg): So this way I managed to upload the photo:

file = new File(filePath);

imagePayload = HttpRequest.BodyPublishers.ofFile(file.toPath())

as Dev stated, no need to convert it using base64
