I am following Graph APIs to download a file from Sharepoint.
I tried this endpoint:
https://graph.microsoft.com/v1.0/drives/{drive_id}/root:/{folder}/{file_name}:/content
And to fetch InputStream using restTemplate:
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.setContentType(MediaType.APPLICATION_JSON);
httpHeaders.set(GraphConstant.AUTHORIZATION, TOKEN);
HttpEntity httpEntity = new HttpEntity(httpHeaders);
String downloadEndPoint = DOWNLOAD_FILE_ENDPOINT.replace(GraphConstant.DRIVE_ID,getDriveId(id)).replace("{folder}",folder).replace(GraphConstant.FILE_NAME, URLEncoder.encode(fileName, GraphConstant.UTF_8).replace("+", "%20"));
ResponseEntity<InputStream> responseEntity = restTemplate.exchange(downloadEndPoint,
HttpMethod.GET,
httpEntity,
InputStream.class);
if(responseEntity.getStatusCode().equals(HttpStatus.OK)){
return responseEntity.getBody();
}
responseEntity.getBody() returns null.
What is the return type of Graph Download file API? Any inputs here?
I am using a SpringBoot application and making calls with restTemplate (not using Microsoft SDK to make graph calls).
Changing ResponseEntity to ResponseEntity<byte[]> solved my problem.
ResponseEntity<byte[]> responseEntity = graphRestTemplate.exchange(DOWNLOAD_FILE_ENDPOINT,
HttpMethod.GET,
httpEntity,
byte[].class,
drive_id,
entity_id,
fileName);

In order to test the Azure DevOp API,
POST https://dev.azure.com/{organization}/{project}/_apis/git/repositories/{repositoryId}/itemsbatch?api-version=6.0
we need to log in first.
HTTP/1.1 203 Non-Authoritative Information
What is the best way to handle authentication in this API testing?
Add tokens in the request headers?
After you get JWT you can use it in the command line like below:
set header Authorization "bearer <TOKEN VALUE>"
You can see this link https://learn.microsoft.com/en-us/aspnet/core/web-api/http-repl/?view=aspnetcore-6.0&tabs=windows#set-http-request-headers
To test the REST API, you need either Testing Tool to drive the API or writing down your own code.
Rest API can be tested with tools like:
Advanced Rest Client
Postman
To write your own code, you could refer to the following sample:
public static async void GetProjects()
{
try
{
var personalaccesstoken = "PAT_FROM_WEBSITE";
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(
new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
Convert.ToBase64String(
System.Text.ASCIIEncoding.ASCII.GetBytes(
string.Format("{0}:{1}", "", personalaccesstoken))));
using (HttpResponseMessage response = await client.GetAsync(
"https://dev.azure.com/{organization}/_apis/projects"))
{
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
}
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
}
I'm looking for a way to convert Office files to PDF.
I found out that Microsoft Graph could be used.
I'm trying to download converted PDF using Microsoft Graph from OneDrive.
I'd like to convert .docx to .pdf.
However, when I sent the following request, I did not receive a response even if I waited.
GET https://graph.microsoft.com/v1.0/users/{id}/drive/root:/test.docx:/content?format=pdf
Also, the error code is not returned.
If syntax is wrong, an error code will be returned as expected.
It will not return only when it is correct.
In addition, I can download the file if I do not convert.
GET https://graph.microsoft.com/v1.0/users/{id}/drive/root:/test.docx:/content
Is my method wrong or else I need conditions?
If possible, please give me sample code that you can actually do.
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
client.BaseAddress = new Uri(graphUrl);
var result = await client.GetAsync("/v1.0/users/xxxxxxxxxxxxxxxxxxxxxxxxx/drive/root:/test.docx:/content?format=pdf");
:
I would like to elaborate a bit Marc's answer by providing a few examples for HttpClient.
Since by default for HttpClient HttpClientHandler.AllowAutoRedirect property is set to True there is no need to explicitly follow HTTP redirection headers and the content could be downloaded like this:
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
client.BaseAddress = new Uri("https://graph.microsoft.com");
var response = await client.GetAsync($"/v1.0/drives/{driveId}/root:/{filePath}:/content?format=pdf");
//save content into file
using (var file = System.IO.File.Create(fileName))
{
var stream = await response.Content.ReadAsStreamAsync();
await stream.CopyToAsync(file);
}
}
In case if follow HTTP redirection is disabled, to download the converted file, your app must follow the Location header in the response as demonstrated below:
var handler = new HttpClientHandler()
{
AllowAutoRedirect = false
};
using (HttpClient client = new HttpClient(handler))
{
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
client.BaseAddress = new Uri("https://graph.microsoft.com");
var response = await client.GetAsync($"/v1.0/drives/{driveId}/root:/{filePath}:/content?format=pdf");
if(response.StatusCode == HttpStatusCode.Redirect)
{
response = await client.GetAsync(response.Headers.Location); //get the actual content
}
//save content into file
using (var file = System.IO.File.Create(fileName))
{
var stream = await response.Content.ReadAsStreamAsync();
await stream.CopyToAsync(file);
}
}
The API doesn't return the converted content directly, it returns a link to the converted file. From the documentation:
Returns a 302 Found response redirecting to a pre-authenticated download URL for the converted file.
To download the converted file, your app must follow the Location header in the response.
Pre-authenticated URLs are only valid for a short period of time (a few minutes) and do not require an Authorization header to access.
You need to capture the 302 and make a 2nd call to the URI in the Location header in order to download the converted file.
In need of some help accessing an external Web API passing along credentials in order to access the methods available. I have included the code below that i use in order to attempt to access the Web API. However, i receive the following error every time i attempt to access it:
"The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
What am i missing or what am i doing wrong? I have been circling around this for a couple days and have tried a couple different techniques but continue to get the same error. Here is one technique that i used.
private static async Task<string> GetAPIToken(string userName, string password, string apiBaseUri)
{
try
{
using (var client = new HttpClient())
{
//setup client
client.BaseAddress = new Uri(apiBaseUri);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//setup login data
var formContent = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string,string>("username",userName),
new KeyValuePair<string,string>("password",password),
});
//send request
HttpResponseMessage responseMessage = await client.PostAsync("Token", formContent);
//get access token from response body
var responseJson = await responseMessage.Content.ReadAsStringAsync();
var jobject = JObject.Parse(responseJson);
return jobject.GetValue("access_token").ToString();
}
}
catch (Exception ex)
{
return null;
}
}
Any help would be greatly appreciated.
Thanks
There is a little bit of a difference when using HTTPS vs HTTP. This question should give you the information you need to fix your problem.
Make Https call using HttpClient
I am using oauth2/token to authenticate my application and get the access_token. Bellow is the java code which is working fine.
private String getToken() throws Exception {
String access_token = "";
String url = "https://login.windows.net/MyApplication_ID_here/oauth2/token";
HttpClient client = HttpClients.createDefault();
HttpPost post = new HttpPost(url);
post.setHeader("Content-Type", "application/x-www-form-urlencoded");
List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
urlParameters.add(new BasicNameValuePair("grant_type", "client_credentials"));
urlParameters.add(new BasicNameValuePair("client_id", "MyApplication_ID_here"));
urlParameters.add(new BasicNameValuePair("client_secret", "MyApplication_secret_here"));
urlParameters.add(new BasicNameValuePair("resource", "https://graph.microsoft.com"));
post.setEntity(new UrlEncodedFormEntity(urlParameters));
HttpResponse response = client.execute(post);
System.out.println("Sending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + post.getEntity());
System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
String responseAsString = EntityUtils.toString(response.getEntity());
System.out.println(responseAsString);
try {
access_token = responseAsString.split(",")[6].split("\"")[3]; // get the access_token from response
} catch (Exception e) {
e.printStackTrace();
return null;
}
return access_token;
}
Response :
{"token_type":"Bearer","expires_in":"3599","ext_expires_in":"0","expires_on":"1493011626","not_before":"1493007726","resource":"https://graph.microsoft.com","access_token":"eyJ0e..."}
then I am using access_token to load the memberOf value which is not working and gives me the Access Token missing or malformed error. Bellow is the java code
private void getMemberOf()
{
HttpClient httpclient = HttpClients.createDefault();
try
{
URIBuilder builder = new URIBuilder("https://graph.windows.net/MyApplication_ID_here/users/test#testABC.onmicrosoft.com/memberOf?api-version=1.6");
URI uri = builder.build();
HttpGet request = new HttpGet(uri);
request.addHeader("Authorization", "Bearer " + access_token);
request.addHeader("Content-Type", "application/json");
HttpResponse response = httpclient.execute(request);
HttpEntity entity = response.getEntity();
System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
if (entity != null) {
System.out.println(EntityUtils.toString(entity));
}
}
catch (Exception e)
{
e.getMessage();
}
}
Response :
Response Code : 401
{"odata.error":{"code":"Authentication_MissingOrMalformed","message":{"lang":"en","value":"Access Token missing or malformed."},"date":"2017-04-24T04:39:38","requestId":"c5aa2abe-9b37-4611-8db1-107e3ec08c14","values":null}}
Can someone please tell me which part of the above request is wrong? Am I not setting access_token correctly?
According to your code , your access token is for resource "https://graph.microsoft.com"(Microsoft Graph API) ,But the access token is used for "https://graph.windows.net"(AAD Graph API) :
URIBuilder builder = new URIBuilder("https://graph.windows.net/MyApplication_ID_here/users/test#testABC.onmicrosoft.com/memberOf?api-version=1.6");
If you want to call Azure AD graph api , you need to get access token for Azure AD Graph API .
I got this issue while performing the CRUD operation on Azure AD B2C service via AD Graph API for user management.
The idea is to get the access token for the resource "graph.windows.net" instead I was using my tenant App Id URI as it was suggested here.

I am trying to get activity stream of my jira instance using the below api and it is not working , can anybody point me in the right direction ?
You should check this page out: https://developer.atlassian.com/docs/atlassian-platform-common-components/activity-streams/consuming-an-activity-streams-feed
The Atom feed of the activity stream works well only if you also log in in your feed reader.
Here is an example of consuming the activity stream through the Jira API using Basic Authentication. This is in C#, but the basic pattern can be applied anywhere:
string myJiraUsername = "username";
string myJiraPassword = "password"; //or API token
string authenticationHeaderValue = Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(myJiraUsername + ":" + myJiraPassword));
System.Net.Http.HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authenticationHeaderValue);
Task<HttpResponseMessage> task = client.GetAsync("https://mycompany.atlassian.net/activity");
task.Wait();
HttpResponseMessage response = task.Result;
string resultOfApiCall = "";
if (response.IsSuccessStatusCode)
{
resultOfApiCall = response.Content.ReadAsStringAsync().Result;
Console.WriteLine("This was returned by your API request:\n" + resultOfApiCall);
}
