java - 向 Azure Graph API 发送 POST 请求时收到 400 Bad request

Question

我正在尝试向 Microsoft Azure Graph API 发送 POST 请求以创建用户。我引用了他们的样本example并且能够成功执行 GET 请求，但不能成功执行 POST。

我的代码如下:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

import javax.naming.ServiceUnavailableException;

import org.json.JSONException;
import org.json.JSONObject;

import com.microsoft.aad.adal4j.AuthenticationContext;
import com.microsoft.aad.adal4j.AuthenticationResult;

public class CreateUser {

    private final static String AUTHORITY = "https://login.microsoftonline.com/common/";
    private final static String CLIENT_ID = "<Client_id>";

    public static void main(String args[]) throws Exception {

        try (BufferedReader br = new BufferedReader(new InputStreamReader(
                System.in))) {
            System.out.print("Enter username: ");
            String username = br.readLine();
            System.out.print("Enter password: ");
            String password = br.readLine();

            // Request access token from AAD
            AuthenticationResult result = getAccessTokenFromUserCredentials(
                    username, password);
            // Get user info from Microsoft Graph
            String userInfo = createUserInGraph(result.getAccessToken());
            System.out.print(userInfo);
        }
   }

    private static AuthenticationResult getAccessTokenFromUserCredentials(
            String username, String password) throws Exception {
        AuthenticationContext context;
        AuthenticationResult result;
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            context = new AuthenticationContext(AUTHORITY, false, service);
            Future<AuthenticationResult> future = context.acquireToken(
                    "https://graph.microsoft.com", CLIENT_ID, username, password,
                    null);
            result = future.get();
        } finally {
            service.shutdown();
        }

        if (result == null) {
            throw new ServiceUnavailableException(
                    "authentication result was null");
        }
        return result;
    }

    private static String createUserInGraph(String accessToken) throws IOException {

        String jsonInputData = "{  \"accountEnabled\": true," + 
                "  \"city\": \"Delhi\"," + 
                "  \"country\": \"India\"," +

                "    \"forceChangePasswordNextSignIn\": false" + 
                "  }," + 
                "  \"officeLocation\": \"131/1105\"," +

        System.out.println("Input: " + jsonInputData);
        URL url = new URL("https://graph.microsoft.com/v1.0/users");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setDoInput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Authorization", "Bearer " + accessToken);
        System.out.println("Access Token: \n" + accessToken);
        System.out.println();
        conn.setRequestProperty("Content-type","application/json; charset=UTF-8");

        OutputStream os = conn.getOutputStream();
        os.write(jsonInputData.getBytes("UTF-8"));
        os.close();
        //display what returns the POST request

        StringBuilder sb = new StringBuilder();  
        int HttpResult = conn.getResponseCode();
        System.out.println("Response code: " + HttpResult);
        if (HttpResult == HttpURLConnection.HTTP_OK) {
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(conn.getInputStream(), "utf-8"));
            String line = null;  
            while ((line = br.readLine()) != null) {  
                sb.append(line + "\n");  
            }
            br.close();
            System.out.println("" + sb.toString());  
        } else {
            System.out.println(conn.getResponseMessage());  
        }
        return null;
    }
}

因此，我收到的错误代码为 400，错误消息为“错误请求”。有人可以解释一下这是什么问题吗？

Answer 1

错误请求问题通常与发送的某些无效数据/格式有关。

查看您的 json，有两件事很突出。请进行这些更改，看看这是否可以解决您的问题。

1. "userPrincipalName": "adamg@alandonaldgmail.onmicrosoft.com"(确保 alandonaldgmail.onmicrosoft.com 是您的 Azure Active Directory 组织的经过验证的域，如果不是并且您错误地使用了它，则将 userPrincipalName 的值更改为“adamg@yourazurereadtenantname.onmicrosoft.com”)

2. “usageLocation”:“IND”(这可能应该只是“IN”，因为它应该是两个字母的国家/地区代码(ISO 标准 3166))
