ASP.NET Core WebAPI 使用CreatedAtRoute通知消费者

一、目的

我想告诉消费者我的api关于新创建的对象的位置

二、方法说明

public virtual Microsoft.AspNetCore.Mvc.CreatedAtRouteResult CreatedAtRoute (string routeName, object routeValues, object content);

Parameters

• routeName:The name of the route to use for generating the URL.
• routeValues:The route data to use for generating the URL.
• content:The content value to format in the entity body.

三、示例代码

这里的Student和StudentDto类就不展示了，比较简单

[ApiController]
[Route("api/{Controller}")]
public class HomeController : Controller
{
    [HttpGet("students")]
    public IActionResult GetStudents()
    {
        return Ok(DbContext.Db.ToList());
    }

    [HttpGet("students/{id}", Name = nameof(GetStudents))]
    public IActionResult GetStudents(Guid id)
    {
        return Ok(DbContext.Db.FirstOrDefault(x => x.Id == id));
    }

    [HttpPost("student")]
    public IActionResult AddStudent([FromForm]Student student)
    {
        var stuDto = new StudentDto()
        {
            Id = Guid.NewGuid(),
            Name = student.FirstName + student.LastName,
            Age = DateTime.Now.Year - student.Birthday.Year
        };
        DbContext.Db.Add(stuDto);
        return CreatedAtRoute(nameof(GetStudents), new { id = stuDto.Id }, stuDto);
    }
}

四、测试

1. 发送Post请求，提交表单

2. 查看返回结果

返回值Body

返回值Headers

3. 复制Location值，发送Get请求，验证结果
