返回 JSON 到 OutputBuffer

Question

我在反序列化 return 将 JSON 字符串返回到输出时遇到问题。

我声明了以下三个类是我从 json2csharp 生成的：

public class Application
{
    public int App_ID { get; set; }
    public string App_Ref { get; set; }
    public string Status { get; set; }
    public string Error_Code { get; set; }
    public string Error_Message { get; set; }
    public string Create_Dt { get; set; }
    public string Modify_Dt { get; set; }
    public string Client_Name { get; set; }
    public string Client_Code { get; set; }
    public string Centrelink_Status { get; set; }

}
public class Response
{
    public List<Application> Applications { get; set; }
    public string Current_Dt { get; set; }
    public string Last_App_Dt { get; set; }
    public int Count { get; set; }
    public int Total { get; set; }
}

public class RootObject
{
    public bool Success { get; set; }
    public Response jsonResponse { get; set; }

}

我的 JSON 回复如下：

    {
      "Success": true,
      "Response": {
        "Applications": [
          {
            "App_ID": 2877582,
            "App_Ref": "Odonnell",
            "Status": "Complete",
            "Error_Code": 0,
            "Error_Message": "",
            "Create_Dt": "2016-10-09 19:28:18.867 +00:00",
            "Modify_Dt": "2016-10-09 19:33:10.810 +00:00",
            "Client_Name": "Aussie Bike Auto & Boat Loans South",
            "Client_Code": "GGT31",
            "Centrelink_Status": "Receiving_Logons"
          },
          {
            "App_ID": 2878070,
            "App_Ref": "alliso",
            "Status": "Quicklink",
            "Error_Code": null,
            "Error_Message": null,
            "Create_Dt": "2016-10-09 21:55:49.220 +00:00",
            "Modify_Dt": "2016-10-09 21:55:49.220 +00:00",
            "Client_Name": "KChristoforidis",
            "Client_Code": "GGT05",
            "Centrelink_Status": "Receiving_Logons"
          }...
    ],
        "Current_Dt": "2016-11-13 22:52:41.581 +00:00",
        "Last_App_Dt": "2016-10-11 01:42:25.470 +00:00",
        "Count": 65,
        "Total": 65
      }
}

我能够从响应中输出 "Success" 布尔值，但是我无法从响应中取回任何其他内容，因为我得到的是 "Object reference not set to an instance of an object." 当我尝试执行以下操作时出错：

foreach (Application app in outPutResponse.jsonResponse.Applications)
{
    ApplicationBuffer.AddRow();
    ApplicationBuffer.AppID = app.App_ID;
    ApplicationBuffer.AppRef = app.App_Ref;
    ApplicationBuffer.Status = app.Status;

}

我也无法 return 对 outputBuffer 的响应 "jsonResponse" 出现错误 "can not implicitly convert jsonResponse to BlobColumn"

我也无法 return 来自 outPutResponse.jsonResponse 的响应值，并出现以下错误：

    RawBuffer.AddRow();
    RawBuffer.ResponseSuccess = outPutResponse.Success;
    RawBuffer.Response.AddBlobData(Encoding.ASCII.GetBytes(outPutResponse.jsonResponse));

'System.Text.Encoding.GetBytes(char[])' 的最佳重载方法匹配有一些无效参数参数 1：无法从 'Script.Response' 转换为 'char[]'

这是我最后的绊脚石，我似乎无法做到这一点。

假设您正在使用 Newtonsoft JSON.Net，因为这是一个聪明的主意。

您已将属性名称更改为 jsonResponse，而实际属性名称为 Response。

如果您想更改名称，您必须使用

修饰属性

[JsonProperty("myproperty_name")]

像这样：

public class Application
{
    [JsonProperty("App_ID")]
    public int App_ID { get; set; }

    [JsonProperty("App_Ref")]
    public string App_Ref { get; set; }

    [JsonProperty("Status")]
    public string Status { get; set; }

    [JsonProperty("Error_Code")]
    public int? Error_Code { get; set; }

    [JsonProperty("Error_Message")]
    public string Error_Message { get; set; }

    [JsonProperty("Create_Dt")]
    public string Create_Dt { get; set; }

    [JsonProperty("Modify_Dt")]
    public string Modify_Dt { get; set; }

    [JsonProperty("Client_Name")]
    public string Client_Name { get; set; }

    [JsonProperty("Client_Code")]
    public string Client_Code { get; set; }

    [JsonProperty("Centrelink_Status")]
    public string Centrelink_Status { get; set; }
}

public class Response
{
    [JsonProperty("Applications")]
    public IList<Application> Applications { get; set; }

    [JsonProperty("Current_Dt")]
    public string Current_Dt { get; set; }

    [JsonProperty("Last_App_Dt")]
    public string Last_App_Dt { get; set; }

    [JsonProperty("Count")]
    public int Count { get; set; }

    [JsonProperty("Total")]
    public int Total { get; set; }
}

public class RootObject
{
    [JsonProperty("Success")]
    public bool Success { get; set; }

    [JsonProperty("Response")]
    public Response jsonResponse { get; set; }
}

虽然我推荐上面的示例，但您也可以使用 Response 而不是 c:

public Response Response { get; set; }
