通过 postman 和使用 java 的代码库调用 microsoft graph beta api

Question

I am already aware to call microsft graph API using postman and code base for v1.0. Question: How to call microsoft graph beta api via postman and codebase using java for beta version.

There are lots of articles related to v1.0 but i do not find any related to beta version. i think, it might be possible that we can call beta version API using custom API call. Please suggest or share any article.

Note: I know it is not recommended to use beta version API but I am working on some POC to test this

Answer 1

I'm not sure if I misunderstand you.

Here's a format of graph api, and you could manage {version} to switch ' beta ' version and ' v1.0 ' version. Here's the description .

{HTTP method} https://graph.microsoft.com/{version}/{resource}?{query-parameters}

You can change the input choice to get different versions of one api.

=============UPDATE============

//js sample call graph api
function callMSGraph(endpoint, token, callback) {
    const headers = new Headers();
    const bearer = `Bearer ${token}`;
    headers.append("Authorization", bearer);    
    const options = {
        method: "GET",
        headers: headers
    };
    fetch(endpoint, options)
        .then(response => response.json())
        .then(response => callback(response, endpoint))
        .catch(error => console.log(error))
}

java sample call graph api, code comes from this

private String getUserInfoFromGraph(String accessToken) throws Exception {
        // Microsoft Graph user endpoint
        URL url = new URL(authHelper.getMsGraphEndpointHost() + "v1.0/me");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();

        // Set the appropriate header fields in the request header.
        conn.setRequestProperty("Authorization", "Bearer " + accessToken);
        conn.setRequestProperty("Accept", "application/json");

        String response = HttpClientHelper.getResponseStringFromConn(conn);

        int responseCode = conn.getResponseCode();
        if(responseCode != HttpURLConnection.HTTP_OK) {
            throw new IOException(response);
        }

        JSONObject responseObject = HttpClientHelper.processResponse(responseCode, response);
        return responseObject.toString();
    }
