C# 如何将前端的json属性分配给API中的多个后端模型？

我有一个React组件，它可以像这样发布到API控制器：

onSubmit={async values => {
    await new Promise(resolve => setTimeout(resolve, 500));
    axios({
        method: "POST",
        url: "/educationalgames/api/acceptentry",
        data: values
    });
    alert(JSON.stringify(values, null, 2));
}}

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

当我点击submit时，我看到它找到的值：

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

上面的数据是我的c#后端API中不同模型的混合属性

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

团队名称、团队电子邮件和培训师属于my team.cs模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

可删除层，部门属于department.cs模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

researchType、numOfStudents和currentState属于我的research.cs模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

我的问题是，我不知道如何转换数据，以便我的API控制器能够读取数据并为匹配的模型属性分配适当的值

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

到目前为止，我的c#controller中有一个：

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

[HttpPost]
public async Task<ActionResult> AcceptEntry([FromBody] ???)

[HttpPost]
public async Task<ActionResult> AcceptEntry([FromBody] CommonModel model) {

 var team = new Team() {
   teamName = model.teamName,
   ...
 }
 var department = new Department() {
   eligiblePlayers = model.eligiblePlayers,
   ...
 }
}

[HttpPost]
公共异步任务AcceptEntry（[FromBody]？？）

我有点不知所措，无法处理这件事

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

有办法吗

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

谢谢

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

teamName、teamEmail和trainer属于我的team.cs模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

eligiblePlayers、department属于department.cs模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

research Type、numOfStudents和currentState属于my research.cs 模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

为什么不在应用程序中创建通用模型

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

public class CommonModel {
  public string teamName {get; set;} 
  teamEmail, 
  eligiblePlayers, 
  department, 
  researchType, 
  numOfStudents, 
  currentState
}

然后，在控制器中：

{
    "eligiblePlayers": [],
    "teamName": "FalconOne",
    "teamEmail": "fc@coma.edu",
    "trainer": "",
    "department": "Physics",
    "researchType": "Meta",
    "numOfStudents": 50,
    "currentState": true
}

[HttpPost]
public async Task<ActionResult> AcceptEntry([FromBody] ???)

[HttpPost]
public async Task<ActionResult> AcceptEntry([FromBody] CommonModel model) {

 var team = new Team() {
   teamName = model.teamName,
   ...
 }
 var department = new Department() {
   eligiblePlayers = model.eligiblePlayers,
   ...
 }
}

[HttpPost]
公共异步任务AcceptEntry（[FromBody]CommonModel）{
var团队=新团队（）{
teamName=model.teamName，
...
}
var部门=新部门（）{
eligiblePlayers=model.eligiblePlayers，
...
}
}

您可以将所有模型包装在一个单独的视图模型中，如图所示：只需为API创建一个新模型即可。您的模型不一定直接与后端模型相关。@DavidG但是如果前端的属性与我的模型不匹配，它们最终如何写入数据库？谢谢就像我说的，你的api模型不一定和你在数据库中使用的相同。在两者之间写一层，在两者之间转换。或者使用像AutoMapper这样的库。哦，我明白了，那么帖子会自动将值放入CommonModel模型吗？只有当React中的值对象与后端的CommonModel类的结构相同时。可能您的values对象是一个包含所有枚举参数的json。Net核心将接收到的json映射到您的类中（本例中为CommonModel）
