Java連接Microsoft Dynamics 365

Question

我需要使用Java連接Microsoft Dynamics 365 CRM，對於Java連接，我只能看到此（ https://msdn.microsoft.com/zh-cn/library/jj602979(v=crm.5).aspx ）鏈接。 誰能告訴我如何使用java連接ms動態。

我唯一需要的是將聯系人從CRM加載到我的應用程序中。

Answer 1

您應該使用WebAPI 。

Web API是Microsoft Dynamics 365（在線和本地）的新增功能，可提供可在多種編程語言，平台和設備上使用的開發體驗。 Web API實現了OData（開放數據協議）版本4.0，這是用於通過豐富數據源構建和使用RESTful API的OASIS標准。

Answer 2

通過鏈接： 連接和數據交換，Java與Microsoft Dynamics，您將獲得有關使用ADFS和OAuth2從Java與“ Dynamics”進行連接的詳盡教程。 所有細節都在那里。 本教程還實現了READ和WRITE操作。

該實現利用Java庫OLingo通過Dynamics應用程序的http端點交換實際的讀寫OData消息。

Answer 3

您可以使用我的GitHub示例 。 我使用adal4j來處理所有身份驗證開銷，它為我提供了一個承載令牌，可用於對組織進行api調用。

import com.microsoft.aad.adal4j.AuthenticationContext;
import com.microsoft.aad.adal4j.AuthenticationResult;
import com.microsoft.aad.adal4j.ClientCredential;
import okhttp3.*;

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.lang.String;
import java.util.concurrent.Future;

public class Main {
    public static void main(String[] args) {

        String authority = "https://login.microsoftonline.com/";
        String resource = "https://msott.crm.dynamics.com";
        String clientId = "64f4cba8-0656-4ccd-8c2a-fd269fe7636f";
        String clientSecret = "";
        String tenantID = "grdegr.onmicrosoft.com";
        ExecutorService service = Executors.newFixedThreadPool(1);
        AuthenticationResult result;

        try {
            AuthenticationContext context = new AuthenticationContext(authority + tenantID, true, service);
            Future<AuthenticationResult> future = context.acquireToken(resource, new ClientCredential(clientId, clientSecret), null);

            result = future.get();
            String accessToken = result.getAccessToken();

            createWithDataReturned(accessToken);
        }
        catch (MalformedURLException e) { }
        catch (InterruptedException e) { }
        catch (ExecutionException e) { }
    }

    // TODO: 5
    // Retrieving customized responses on POST method:
    public static void createWithDataReturned(String accessToken) {
        try {
            OkHttpClient client = new OkHttpClient();

            MediaType mediaType = MediaType.parse("application/json; charset=utf-8");
            RequestBody body = RequestBody.create(mediaType, "{" +
                    "\"name\": \"Sample Postman Account\"," +
                    "\"creditonhold\": false," +
                    "\"address1_latitude\": 47.639583," +
                    "\"description\": \"This is the description of the sample account\"," +
                    "\"revenue\": 5000000," +
                    "\"accountcategorycode\": 1" +
                    "}");
            Request request = new Request.Builder()
                    .url("https://msott.api.crm.dynamics.com/api/data/v9.0/accounts?$select=name,creditonhold,address1_latitude,description,revenue,accountcategorycode,createdon")
                    .post(body)
                    .addHeader("OData-MaxVersion", "4.0")
                    .addHeader("OData-Version", "4.0")
                    .addHeader("Accept", "application/json")
                    .addHeader("Content-Type", "application/json; charset=utf-8")
                    .addHeader("Prefer", "return=representation")
                    .addHeader("Authorization", "Bearer " + accessToken)
                    .addHeader("cache-control", "no-cache")
                    .addHeader("Postman-Token", "472f1651-c4e1-47c1-8a5c-6f70636181b0")
                    .build();

            Response response = client.newCall(request).execute();

            String dataReturnedFromCreate = response.body().string();

            System.out.println();
        }
        catch (IOException e) { }
    }
}
