c# - 如何传递类对象 Postman

Question

我有一个需要三个参数的 api，一个字符串(数据类型)、一个类(eloanInput)和一个 bool 值(isCluster)

public HttpResponseMessage getEloanExcel(string dataType, EloanInput eloanInput, bool isCluster = false) 
{
   var exportDataService = new ExportDataService();
   var exportExcel = new ExportExcel(dataType);
   var inputParams = new CaseSearch.EloanInput();
   inputParams.SEARCH_TYPE = eloanInput.SEARCH_TYPE;
   inputParams.COUNTY_ID = eloanInput.COUNTY_ID;
   inputParams.TOWN_ID = eloanInput.TOWN_ID;
   inputParams.HOUSE_TYPES = (eloanInput.HOUSE_TYPES[0] == "-1" && eloanInput.HOUSE_TYPES.Count() == 1) ? null : eloanInput.HOUSE_TYPES;
   inputParams.HouseProject = (eloanInput.HouseProject[0] == "-1" && eloanInput.HouseProject.Count() == 1) ? null : eloanInput.HouseProject;
   inputParams.PUB_START_DT = eloanInput.PUB_START_DT;
   inputParams.PUB_END_DT = eloanInput.PUB_END_DT;
}

如下图所示:

我在Postman中测试API时出现问题，我使用key,value方法传递我的参数，只有eloanInput得到null，它没有得到我传递给它的值，但其他参数确实得到了值由 postman 。

    [Key]         [Value] 

    dataType      'Eloan' 

    eloanInput  { "SEARCH_TYPE": 2,
                "COUNTY_ID": "-1",
               "TOWN_ID": "-1",
               "PUB_START_DT": "2006/11/22",
               "PUB_END_DT": "2006/12/15",
               "HOUSE_TYPES": ["01", "02", "03"],
               "HouseProject": [1, 2, 3, 4, 5],
               "DONE_START_DT": "88",
               "DONE_END_DT": "108",
               "FLOOR_FROM": "1",
               "FLOOR_TO": "18",
               "BUILD_AREA_FROM": "2",
               "BUILD_AREA_TO": "48",
               "CASE_TYPE": [1, 2, 3, 4, 5],
               "CASE_CATEGORY": [1, 2, 3, 4],
               "CASENM_KEYWORD": "12"} 

   isCluster    false

postman 请求:

我将从请求正文(在 [FromBody] 的帮助下)发送该数据，并将其更改为 [HttpPost] 方法而不是 [HttpGet]。

您更新的方法代码:

[HttpPost]
public HttpResponseMessage getEloanExcel(string dataType, [FromBody] EloanInput eloanInput, bool isCluster = false)
{
   // your code
}

以及 Postman 的请求:
