通过基于REST合约的API从Acumatica导出记录

本主题将演示如何通过基于REST合约的API从Acumatica ERP导出记录。与Acumatica ERP基于屏幕的API不同，基于合同的API同时提供SOAP和REST接口。有关基于契约的API的更多信息，请参阅在单个REST调用中导出数据 在本例中，您将探索如何通过基于REST合约的API在一次调用中从Acumatica ERP导出以下数据：

• 应用程序中存在的所有库存项
• 类型中的所有销售订单

如果需要从Acumatica ERP导出记录，请使用以下URL：

以下是上文所有示例中使用的RestService类的实现，用于与Acumatica ERP基于合同的web服务交互，供您参考：

public class RestService : IDisposable
{
    private readonly HttpClient _httpClient;
    private readonly string _acumaticaBaseUrl;
    private readonly string _acumaticaEndpointUrl;

    public RestService(string acumaticaBaseUrl, string endpoint,
        string userName, string password,
        string company, string branch)
    {
        _acumaticaBaseUrl = acumaticaBaseUrl;
        _acumaticaEndpointUrl = _acumaticaBaseUrl + "/entity/" + endpoint + "/";
        _httpClient = new HttpClient(
            new HttpClientHandler
            {
                UseCookies = true,
                CookieContainer = new CookieContainer()
            })
        {
            BaseAddress = new Uri(_acumaticaEndpointUrl),
            DefaultRequestHeaders =
            {
                Accept = {MediaTypeWithQualityHeaderValue.Parse("text/json")}
            }
        };

        var str = new StringContent(
            new JavaScriptSerializer()
                .Serialize(
                    new
                    {
                        name = userName,
                        password = password,
                        company = company,
                        branch = branch
                    }),
                    Encoding.UTF8, "application/json");

        _httpClient.PostAsync(acumaticaBaseUrl + "/entity/auth/login", str)
            .Result.EnsureSuccessStatusCode();
    }

    void IDisposable.Dispose()
    {
        _httpClient.PostAsync(_acumaticaBaseUrl + "/entity/auth/logout",
            new ByteArrayContent(new byte[0])).Wait();
        _httpClient.Dispose();
    }

    public string GetList(string entityName)
    {
        var res = _httpClient.GetAsync(_acumaticaEndpointUrl + entityName)
            .Result.EnsureSuccessStatusCode();

        return res.Content.ReadAsStringAsync().Result;
    }

    public string GetList(string entityName, string parameters)
    {
        var res = _httpClient.GetAsync(_acumaticaEndpointUrl + entityName + "?" + parameters)
            .Result.EnsureSuccessStatusCode();

        return res.Content.ReadAsStringAsync().Result;
    }
}

我真希望我在6个月前找到了这个！您好，是否有一个端点供我在登录后调用，以获取Acumatica安装版本的默认端点字符串？（“在你的例子中是6.00.001”）看看他们github上的一个示例控制台应用程序，它只是硬编码的？？？
