在 Sage One API 中创建“采购发票”时遇到问题。无论我对传入的数据进行什么更改，我似乎都会收到 500 内部服务错误，并且没有包含任何有意义信息的详细响应。无论我输入什么数据（只有错误代码字段中的 GUID 和服务器时间发生变化），响应总是相同的。响应如下：

{
"$diagnoses": [
{
  "$severity": "error",
  "$dataCode": "UnexpectedError",
  "$message": "Unexpected error",
  "$source": {
    "serverTime": "2016-04-29T15:48:11.637+00:00",
    "errorCode": "3b83e1b5-164d-42d4-95b3-3479b09c93f1",
    "requestPath": "/api/v2/purchase_invoices",
    "queryString": "",
        "requestMethod": "POST"
      }
     }
  ]
}

我很肯定这不是授权问题，因为我在此之前获取并创建了其他数据类型。这包括创建采购发票所需的联系人。

我已经关注了他们自助服务网站上提供的信息。我还从他们的基本SDK开始，作为我正在使用的大多数底层流程的基础。我已经重写了大部分底层结构，最初认为它可能是由 SDK 引起的，这导致我遇到同样的情况——我只得到 500 个内部服务错误作为响应。

这使我相信这是参数本身的问题，因为文档在中间列中列出的参数与右列中示例调用中的数据之间存在一些差异。具体来说，该示例具有额外的字段，例如“extra_reference”，并且在中间列中未列出的行项目“product_id”和“product_code”中。

这是调用的一些相关代码，再次记住基本架构是他们的，并进行了一些程序修改以适应我当前的架构，但不影响实际调用：

    protected override List<KeyValuePair<string, string>> GetPostDataValuesForCreate(
        SageOnePurchaseInvoice objectToCreate)
    {
        List<KeyValuePair<string, string>> postData = new List<KeyValuePair<string, string>>();

        postData.Add(new KeyValuePair<string, string>("expense[contact_id]", objectToCreate.ContactId.ToString()));
        postData.Add(new KeyValuePair<string, string>("expense[date]", objectToCreate.Date));
        postData.Add(new KeyValuePair<string, string>("expense[due_date]", objectToCreate.DueDate));

        if (!string.IsNullOrWhiteSpace(objectToCreate.Reference))
        {
            postData.Add(new KeyValuePair<string, string>("expense[reference]", objectToCreate.Reference));
        }

        if (objectToCreate.ProjectId != 0)
        {
            postData.Add(new KeyValuePair<string, string>("expense[project_id]", objectToCreate.ProjectId.ToString()));
        }

        if (!string.IsNullOrWhiteSpace(objectToCreate.Notes))
        {
            postData.Add(new KeyValuePair<string, string>("expense[notes]", objectToCreate.Notes));
        }


        for (int i = 0; i < objectToCreate.LineItems.Length; i++)
        {
            string index = "expense[line_items_attributes][" + i.ToString() + "][";
            postData.Add(new KeyValuePair<string, string>(index + "description]", objectToCreate.LineItems[i].Description));
            postData.Add(new KeyValuePair<string, string>(index + "ledger_account_id]", objectToCreate.LineItems[i].LedgerAccount.Id.ToString()));
            postData.Add(new KeyValuePair<string, string>(index + "quantity]", objectToCreate.LineItems[i].Quantity.ToString()));
            postData.Add(new KeyValuePair<string, string>(index + "unit_price]", objectToCreate.LineItems[i].UnitPrice.ToString()));
        }

        return postData;
    }

下面是创建和执行 Web 请求的实际方法：

public static string Create(Uri baseUrl, List> bodyParams, string token, string signingSecret) { string result;

        string nonce = GenerateNonce();
        HttpWebRequest sageOneWebRequest = WebRequest.Create(baseUrl) as HttpWebRequest;

        string PostParams = ConvertPostParams(bodyParams);

        string signatureString = GetSignatureString(baseUrl, null, bodyParams, nonce, WebRequestMethods.Http.Post);
        string signingKey = GetSigningKey(token, signingSecret);
        string signature = GenerateHmac(signingKey, signatureString);

        sageOneWebRequest.AllowAutoRedirect = true;
        sageOneWebRequest.Accept = "*/*";
        sageOneWebRequest.UserAgent = "Itemize";
        sageOneWebRequest.Headers.Add("X-Signature", signature);
        sageOneWebRequest.Headers.Add("X-Nonce", nonce);
        sageOneWebRequest.ContentType = "application/x-www-form-urlencoded";
        sageOneWebRequest.Timeout = 100000;
        sageOneWebRequest.Headers.Add("Authorization", "Bearer " + token);
        sageOneWebRequest.Method = WebRequestMethods.Http.Post;

        using (StreamWriter requestWriter = new StreamWriter(sageOneWebRequest.GetRequestStream()))
        {
            try
            {
                requestWriter.Write(PostParams);
            }
            catch(Exception ex)
            {
                throw new Exception("Exception thrown writing Post Params to Body", ex);
            }
        }

        try
        {
            using (WebResponse response = sageOneWebRequest.GetResponse())
            {
                Stream dataStream = response.GetResponseStream();
                using (StreamReader reader = new StreamReader(dataStream))
                {
                    result = reader.ReadToEnd();
                }
            }
        }
        catch (WebException webex)
        {
            //This is where the error is caught
            Logger.Error("Web Exception while processing Sage One Web Request: ", webex);
            string text;

            using (var sr = new StreamReader(webex.Response.GetResponseStream()))
            {
                text = sr.ReadToEnd();
            }

            result = null;
            throw new Exception("Web Exception thrown processing Sage One Request", webex);
        }
        catch (Exception ex)
        {
            Logger.Error("Exception while processing Sage One Web Request: ", ex);
            result = null;
            throw new Exception("Exception thrown processing Sage One Request", ex);
        }

        return result;
    }

任何有关此问题的帮助将不胜感激！谢谢！

编辑：关于下面的建议，遵循的实际 URL 路径是“api.sageone.com/accounts/v2/purchase_invoices”，而不是收到的错误中记录的请求路径。

根据错误响应，请求路径看起来不正确。它显示“requestPath”：“/api/v2/purchase_invoices”

但文档显示 /accounts/v2/purchase_invoices

您正在发布到/purchase_invoices，但您的参数适用于expense。请使用purchase_invoice名称来包装您的参数。
