我正在用Java编写一个简单的Android应用程序，最近实现了从Microsoft Dynamics CRM中为用户检索令牌（我在Azure中创建了一个连接的应用程序，获得了应用程序ID，秘密等） .
我希望此应用程序的其他用户能够连接到他们的CRM和组织 .
现在我正在尝试将令牌与REST API一起使用并获得401错误 . 在这里阅读所有相关答案，没有任何帮助 . 我正在使用的代码：
//retrieved the authorization code by this url:
mAuthorizationUrl = Configuration.AUTHORIZE_ENDPOINT + "?response_type=code&client_id="
+ Configuration.CLIENT_ID + "&redirect_uri=" + Configuration.REDIRECT_URI;
...
//Retrieving access_token:
String body_content = "grant_type=authorization_code&client_id=" +
Configuration.CLIENT_ID + "&redirect_uri=" + Configuration.REDIRECT_URI
+ "&code=" + code + "&resource=" + Configuration.CLIENT_ID;
//I don't have app URI (resource) in Azure, so I used app id (client id).
//This worked (see above).
RequestBody body = RequestBody.create(
MediaType.parse("application/x-www-form-urlencoded; charset=utf-8"),
body_content);
Request request = new Request.Builder()
.url(Configuration.TOKEN_RETRIEVAL_ENDPOINT)
.post(body)
.build();
Response response = new OkHttpClient().newCall(request).execute();
String responseString = response.body().string();
JSONObject json = new JSONObject(responseString);
String token = json.getString("access_token");
//NOT WORKING CODE:
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.protocols(Collections.singletonList(Protocol.HTTP_1_1))
.build();
Map<String, String> headers = new ArrayMap<>();
headers.put("Authorization", "Bearer " + token));
headers.put("Accept", "application/json");
request = new Request.Builder()
.url(Configuration.REST_ENDPOINT)
.headers(Headers.of(headers))
.build();
try {
response = okHttpClient
.newCall(request)
.execute();
statusCode = response.code();
}
...
//401 UNAUTHORIZED
我使用的 endpoints ：
AUTHORIZE_ENDPOINT = https://login.microsoftonline.com/common/oauth2/authorize
TOKEN_RETRIEVAL_ENDPOINT = https://login.microsoftonline.com/common/oauth2/token
REST_ENDPOINT = url_to_crm / api / data / v9.0 /
