D365商业中心，我们需要使用C＃代码在项中创建记录

问题描述

我们需要创建一个自己的C＃WebAPI项目，该项目将连接Business Central并将数据插入/更新到Items中。进行搜索之后，我们发现可以使用下面链接中给出的Business Central API来实现这一点。：//docs.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-develop-connect-apps

在这里，我们听不懂

我们应该如何连接到Business Central？
我们如何调用项API以及参数是什么？
我们如何查看可用API的列表？
我们为什么需要创建其他连接应用程序？

如果有人拥有C＃代码段/示例，请与我们分享，这对我们真的很有帮助。

或者像CRM SDK一样，有没有可用的SDK？

解决方法

我们应该如何连接到Business Central？

如果您要谈论使用代码将其连接到BC，则将需要Business Central用户的用户名和Web访问密钥，该密钥与AAD用户凭据不同。

我们如何调用商品API和参数是什么？

请找到以下示例代码，这些代码可能有助于您了解如何调用API

    string url = "https://api.businesscentral.dynamics.com/v2.0/<<Your Environment Name>>/api/v1.0/companies(<<GUID of the company for which item/items needs to be retrieved/added/updated>>)/items";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    HttpClient httpClient = new HttpClient();

    String username = "<<UserName>>";
    String password = "<<WebAccessKey>>";
    String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(username + ":" + password));

    //Get Request for all Items
    HttpRequestMessage readRequest = new HttpRequestMessage(HttpMethod.Get,url);
    readRequest.Headers.Add("Authorization","Basic " + encoded);
    HttpResponseMessage readResponse = httpClient.SendAsync(readRequest).Result;
    string content = string.Empty;

    using (StreamReader stream = new StreamReader(readResponse.Content.ReadAsStreamAsync().Result))
    {
        content = stream.ReadToEnd();
    }

    //Get Request for a specific Item

    string specificItemURl = url + "(<<Guid of the item to be reteieved>>)";
    HttpRequestMessage readSpecificRequest = new HttpRequestMessage(HttpMethod.Get,specificItemURl);
    readSpecificRequest.Headers.Add("Authorization","Basic " + encoded);
    HttpResponseMessage readSpecificResponse = httpClient.SendAsync(readSpecificRequest).Result;
    string specificItem = string.Empty;

    using (StreamReader streamSpecificItem = new StreamReader(readSpecificResponse.Content.ReadAsStreamAsync().Result))
    {
        specificItem = streamSpecificItem.ReadToEnd();
    }

    //Create Request
    string jsonObject = "{'number':'18962-S','displayName':'ATHENS Desk 3','type':'Inventory','itemCategoryId':'6d4e5f4d-8ad1-ea11-bb85-000d3a2a9e6e','itemCategoryCode':'TABLE','blocked':false,'baseUnitOfMeasureId':'354f6647-8ad1-ea11-bb85-000d3a2a9e6e','gtin':'','unitPrice':1000.8,'priceIncludesTax':false,'unitCost':780.7,'taxGroupId':'fc4c5f4d-8ad1-ea11-bb85-000d3a2a9e6e','taxGroupCode':'FURNITURE','baseUnitOfMeasure':{'code':'PCS','displayName':'Piece','symbol':null,'unitConversion':null}}";
    HttpRequestMessage createRequest = new HttpRequestMessage(HttpMethod.Post,url);  
    createRequest.Content = new StringContent(jsonObject,Encoding.UTF8,"application/json");
    createRequest.Headers.Add("Authorization","Basic " + encoded);
    HttpResponseMessage createResponse = httpClient.SendAsync(createRequest).Result;

我们如何查看可用的API列表？

您将需要具有管理角色的用户登录到Business Central实例。登录后，从功能区上单击Services，然后选择Web Services。您应该能够查看所有api端点。

希望这可以帮助您实现所要达到的目标。
