我知道java，azure ad和power bi，我想测试使用azure ad java library（ADAL）将数据推送到power bi：http://innerdot.com/azure/authenticating-to-azure-resource-manager-using-java
我已经创建了一个netbeans项目并使用了这段代码：http://innerdot.com/azure/authenticating-to-azure-resource-manager-using-java并对其进行了测试，以便我知道我有权访问我的azure广告应用程序。
在Power BI文档中，我们会告诉您注册您的应用并获取身份验证令牌，以帮助您使用API发送GET / POST ..请求
我使用了在Github上找到的示例代码。然而，按照power bi apiary docs中的例子，我得到了一个＆＃34; 403＆＃34;或＆＃34; 404＆＃34; http响应状态。
public class ApplicationAuthExample {
private final static String AUTHORIZATION_ENDPOINT = "https://login.microsoftonline.com/";
private final static String ARM_ENDPOINT = "https://management.azure.com/";
private static final boolean DEV_MODE = true;
public static void main(String[] args) throws Exception {
String username = null;
String credential = null;
String tenantId = null;
String clientId = null;
String subscriptionId = null;
if (DEV_MODE) {
username = "name.name@entity.com";
credential = "******";

subscriptionId = "16bxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
} else {
if ((!args[0].equals("service-principal") && !args[0].equals("user"))
|| (args[0].equals("user") && args.length != 6)
|| (args[0].equals("service-principal") && args.length != 5)) {
System.out.println("Usage:");
System.out.println(" user <username> <password> <client id> <tenant id> <subscription id>");
System.out.println(" service-principal <password> <client id> <tenant id> <subscription id>");
System.exit(1);
}
int idx = 1;
if (args[0].equals("user")) {
username = args[idx++];
}
credential = args[idx++];
clientId = args[idx++];
tenantId = args[idx++];
subscriptionId = args[idx++];
}
// use adal to Authenticate
AuthenticationContext context = null;
AuthenticationResult result = null;
ExecutorService service = null;
try {
service = Executors.newFixedThreadPool(1);
String url = AUTHORIZATION_ENDPOINT + tenantId + "/oauth2/authorize";
context = new AuthenticationContext(url,
false,
service);
Future<AuthenticationResult> future = null;
if (username == null) {
System.out.println("username = null");
ClientCredential cred = new ClientCredential(clientId, credential);
future = context.acquireToken(ARM_ENDPOINT, cred, null);
} else {
future = context.acquireToken(ARM_ENDPOINT, clientId,
username, credential, null);
}
result = future.get();
} catch (Exception ex) {
System.out.println("Exception occurred:");
ex.printStackTrace();
System.exit(1);
} finally {
service.shutdown();
}
// make a request to list available providers
String url = ARM_ENDPOINT
+ "subscriptions/" + subscriptionId
+ "/providers"

// String url = "https://api.powerbi.com/v1.0/myorg/datasets";
String body = null;
try {
//final HttpClient httpClient = new DefaultHttpClient();

//HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000);
RequestConfig requestConfig = RequestConfig.custom()
.setSocketTimeout(5000)
.setConnectTimeout(5000)
.setConnectionRequestTimeout(5000)
.build();
HttpGet httpGet = new HttpGet(url);
httpGet.setConfig(requestConfig);
System.out.println("url : "+url);
httpGet.addHeader("Authorization", "Bearer " + result.getAccessToken());
// httpGet.setHeader("Authorization", "Bearer " + result.getAccessToken());
// System.out.println("token : "+result.getAccessToken());
HttpResponse response = httpClient.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
System.out.println("status : "+statusCode);
if(statusCode == 403){
System.out.println(statusCode+": acces denied");
}
HttpEntity entity = response.getEntity();
InputStream instream = entity.getContent();
StringBuilder sb = new StringBuilder();
BufferedReader r = new BufferedReader(new InputStreamReader(instream), 1000);
for (String line = r.readLine(); line != null; line = r.readLine()) {
sb.append(line);
}
instream.close();
body = sb.toString();
} catch (Exception ex) {
System.out.println(ex.toString());
System.exit(1);
}
System.out.println("body : "+body);
}
}
感谢您的帮助。

众所周知，代码中的端点仅用于Azure上的服务，而不适用于PowerBI。请按照PowerBI官方document设置端点进行身份验证，并查看文档Push data into a Power BI Dashboard以了解如何开始使用。
对于authenticating to PowerBI service，请根据您的需要注册客户端应用或需要不同身份验证的网络应用。
我在GitHub中搜索了sample，其中包含使用Java获取PowerBI身份验证访问令牌的代码，请参阅https://github.com/satalyst/powerbi-rest-java/blob/master/src/main/java/com/satalyst/powerbi/impl/Office365Authenticator.java。
希望它有所帮助。
如有任何疑虑，请随时告诉我。

在C＃中测试并返回java之后，我终于设法建立了连接并获得了一个有效的令牌：
public class ApplicationAuth {
public static void main(String[] args) throws Exception {
String username = null;
String credential = null;
String clientId = null;
username = "xxxx.xxxxx@company.com";
credential = "************";
clientId = "50xxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
// use adal to Authenticate
AuthenticationContext context = null;
AuthenticationResult result = null;
ExecutorService service = null;
try {
service = Executors.newFixedThreadPool(1);
String url = "https://login.windows.net/common/oauth2/authorize";
context = new AuthenticationContext(url,
false,
service);
Future<AuthenticationResult> future = null;
if (username==null) {
System.out.println("username = null");
ClientCredential cred = new ClientCredential(clientId, credential);
future = context.acquireToken("https://analysis.windows.net/powerbi/api", cred, null);
} else {
future = context.acquireToken("https://analysis.windows.net/powerbi/api", clientId,
username, credential, null);
}
result = future.get();
} catch (Exception ex) {
System.out.println("Exception occurred:");
ex.printStackTrace();
System.exit(1);
} finally {
service.shutdown();
}
String body = null;
String token = result.getAccessToken();
try {
DatasetsHandler datasetH = new DatasetsHandler();
String data = "{\"name\": \"JavaDatasetTest\", \"tables\": " +
"[{\"name\": \"Product\", \"columns\": " +
"[{ \"name\": \"ProductID\", \"dataType\": \"Int64\"}, " +
"{ \"name\": \"Name\", \"dataType\": \"string\"}, " +
"{ \"name\": \"Category\", \"dataType\": \"string\"}," +
"{ \"name\": \"IsCompete\", \"dataType\": \"bool\"}," +
"{ \"name\": \"ManufacturedOn\", \"dataType\": \"DateTime\"}" +
"]}]}";
//datasetH.CreateDataset(data, token);
System.out.println("after creating dataset");
body = datasetH.GetDatasets(token);
String datasetID = datasetH.GetDatasetID(token);
System.out.println("dataset ID: "+datasetID);
String rows = "{\"rows\":" +
"[{\"ProductID\":1,\"Name\":\"Adjustable Race\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
"{\"ProductID\":2,\"Name\":\"LL Crankarm\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
"{\"ProductID\":3,\"Name\":\"HL Mountain Frame - Silver\",\"Category\":\"Bikes\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}]}";
String resu = datasetH.AddRows( datasetID, token, "Product", rows);
}catch (Exception ex) {
System.out.println(ex.toString());
System.exit(1);
}
// System.out.println("body : "+body); //{"value":[]}
}
}
以下是我使用的方法：
public class DatasetsHandler {
public String powerBIDatasetsApiUrl = "https://api.powerbi.com/v1.0/myorg/datasets";
public String GetDatasets(String token) throws IOException{
HttpRequests httpRequest = new HttpRequests();
HttpResponse response = httpRequest.HttpHeaderParams(token, powerBIDatasetsApiUrl, "GET", "");
HttpEntity entity = response.getEntity();
InputStream instream = entity.getContent();
StringBuilder sb = new StringBuilder();
BufferedReader r = new BufferedReader(new InputStreamReader(instream), 1000);
for (String line = r.readLine(); line != null; line = r.readLine()) {
sb.append(line);
}
instream.close();
String body = sb.toString();
return body;
}
public void CreateDataset(String data, String token) throws IOException{
HttpRequests httpRequest = new HttpRequests();
HttpResponse response = httpRequest.HttpHeaderParams(token, powerBIDatasetsApiUrl, "POST", data);
System.out.println("createDataset response: "+response.getStatusLine().getStatusCode());
HttpEntity entity = response.getEntity();
System.out.println("entity: "+entity);
InputStream instream = entity.getContent();
StringBuilder sb = new StringBuilder();
BufferedReader r = new BufferedReader(new InputStreamReader(instream), 1000);
for (String line = r.readLine(); line != null; line = r.readLine()) {
sb.append(line);
}
instream.close();
String body = sb.toString();
System.out.println("created dataset");
}
public String GetDatasetID(String token) throws IOException{
int id_count = 0;
DatasetsHandler DatasetH = new DatasetsHandler();
String result = DatasetH.GetDatasets(token);
JSONObject jObject = new JSONObject(result);
JSONArray geodata = jObject.getJSONArray("value");
for (int i = 0; i<geodata.length(); i++){
try{
JSONObject cdataset = geodata.getJSONObject(i);
id_count = id_count +1;
}catch (JSONException e) {
// If id doesn't exist, this exception is thrown
}
}
JSONObject cdataset = geodata.getJSONObject(id_count -1);
String Id = cdataset.getString("id");
System.out.println("get dataset name : "+cdataset.getString("name"));
System.out.println("get dataset id : "+cdataset.getString("id"));
return Id;
}
public String AddRows(String DatasetID, String token, String TableName, String rows) throws IOException{
String url = "https://api.powerbi.com/v1.0/myorg/datasets/"+DatasetID+"/tables/"+TableName+"/rows";
HttpRequests httpRequest = new HttpRequests();
HttpResponse response = httpRequest.HttpHeaderParams(token, url, "POST", rows);
System.out.println("Rows Added");
return response.getEntity().toString();
}
}
和HttpHandelr：
public class HttpRequests {
public HttpRequestBase httpRequest;
public static Gson gson = new Gson();
public HttpResponse HttpHeaderParams (String token, String powerBIApiUrl, String method, String body) throws IOException {
final HttpClient httpClient = HttpClientBuilder.create().build();
//JSONObject jsonObj = new JSONObject(body);
StringEntity dataset = new StringEntity(body);
RequestConfig requestConfig = RequestConfig.custom()
.setSocketTimeout(5000)
.setConnectTimeout(5000)
.setConnectionRequestTimeout(5000)
.build();
if("GET".equals(method)){
httpRequest = new HttpGet(powerBIApiUrl);
}else if("POST".equals(method)){
System.out.println("===POST METHOD");
httpRequest = new HttpPost(powerBIApiUrl);
((HttpPost)httpRequest).setEntity(dataset);
System.out.println("get entity: "+((HttpPost)httpRequest).getEntity());
}
System.out.println("TOKEN: "+token);
httpRequest.setConfig(requestConfig);
httpRequest.addHeader("Authorization", "Bearer " + token);
httpRequest.setHeader("Content-Type", "application/json");
httpRequest.setHeader("ContentLength", "\""+body.length()+"\"");
HttpResponse response = httpClient.execute(httpRequest);
System.out.println("response: "+Arrays.toString(response.getAllHeaders()));
System.out.println("response: "+response.getStatusLine().getStatusCode());
return response;
}
}
我希望它有所帮助：）
