如何传递类对象邮递员

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）和一个布尔值（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;
}

就像下面的图片一样：

在Postman中测试API时遇到问题，我使用键，值方法传递参数，只有eloanInput获取null，它没有获取传递给我的值，但是其他参数确实获取了值由邮递员。

    [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

邮递员请求

Answer 1

我会（通过[FromBody]的帮助）从请求正文发送数据，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
}

和邮递员的请求：
