Json ASP.NET 核心 WebAPI 中没有模型绑定的请求

Question

如何在没有模型绑定的情况下使用 ASP.NET Core WebAPI 处理 json 请求？

我有一百多个API需要转移到ASP.NET Core WebAPI，但我无法为每个API设计一个模型，因为数量太多了。

此外，我还需要使用Swagger，所以不能使用IActionResult Post(string json)或IActionResult Post(JObject obj).

这样的字符串解析

控制器代码（有错误）：

[ApiController]
[Route("[controller]")]
public class TestController : ControllerBase
{
    public class Person { public int Age { get; set; } }
    [HttpPost]
    public IActionResult Post([FromBody] string name, Person person)
    {
        return Ok(new
        {
            Name = name,
            person.Age
        });
    }
}

邮递员：

POST /Test HTTP/1.1
Host: localhost:5000
Content-Type: application/json
Content-Length: 68

{
    "Name": "Test",
    "Person": {
        "Age": 10
    }
}

当前API接口：

bool InsertPoint(PointInfo point);
bool[] InsertPoints(PointInfo[] points);
bool RemovePoint(string pointName);
bool[] RemovePoints(string[] pointNames);
string[] Search(SearchCondition condition, int count);
...

我想在控制器中做什么：

[HttpPost]
[SomeJsonBodyAttribute]
public IActionResult InsertPoint(PointInfo point);
[HttpPost]
[SomeJsonBodyAttribute]
public IActionResult InsertPoints(PointInfo[] points);
[HttpPost]
[SomeJsonBodyAttribute]
public IActionResult RemovePoint(string pointName);
[HttpPost]
[SomeJsonBodyAttribute]
public IActionResult RemovePoints(string[] pointNames);
[HttpPost]
[SomeJsonBodyAttribute]
public IActionResult Search(SearchCondition condition, int count);
...

我想在请求中做什么：

移除点

POST /Point/RemovePoint HTTP/1.1
Content-Type: application/json

{
    "pointName": "Test"
}

搜索

POST /Point/Search HTTP/1.1
Content-Type: application/json

{
    "condition": {
        ...
    },
    "count": 10
}

请务必在您的 project.You 中添加 Newtonsoft 支持可参考以下答案：

那么你可以得到如下数据：

[HttpPost]
public IActionResult Post([FromBody] JObject obj)
{
    //for list model:
    //obj["Person"][0]["Age"].ToString()
    return Ok(new { Name = obj["Name"].ToString(), Age = obj["Person"]["Age"].ToString() });
}

与json:

{
    "Name": "Test",
    "Person": {
        "Age": 10
    }
}

结果：
