webapi 获取参数值的几种方式

[FromRoute(Name="名字")],捕捉的值会被自动赋值给Action中同名的参数；如果名字不一致，可以用[FromRoute(Name="名字")]

//前端传入
export async function workOrderWithdrawApprove() {
    return requestClient.post('/workOrder/withdrawApprove/'+ 10086);
}

//后端接收
[HttpPost("{workorderId}")]
public IActionResult WithdrawApprove([FromRoute] int workorderId)
{
    return Ok("ok");  
}

 

[FromQuery]来获取QueryString中的值。如果名字一致，只要为参数添加[FromQuery]即可；而如果名字不一致，[FromQuery(Name = 名字)]

//前端传递
export async function workOrderWithdrawApprove(workorderId: number) {
    return requestClient.post('/workOrder/withdrawApprove?workorderId='+workorderId);
}

//后端接收
[HttpPost]
public IActionResult WithdrawApprove([FromQuery] int workorderId)
{
    return Ok(new { code = 0, data = true });
}

 

[FromForm] 从Content-Type为multipart/form-data的请求中获取数据的[FromForm]

[FromBody]：从请求正文中获取值。

//前端传入
export async function workOrderWithdrawApprove() {
    return requestClient.post('/workOrder/withdrawApprove',{pageIndex: 1, pageSize: 10, type: "乌鸦坐飞机"});
}

//后端接收
public class A
{
    public int pageIndex { get; set; }
    public int pageSize { get; set; }
    public string type { get; set; }
}
[HttpPost]
public IActionResult WithdrawApprove([FromBody] A a)
{
    return Ok(a);
}

 

[FromHeader]从请求报文头中获取值的[FromHeader]
下面举例: 

[HttpGet("BlogByComposite/{title}")]
public Blog GetBlogByBody(string name, [FromRoute(Name = "title")] string title, string contentt, [FromQuery(Name = "typeId")] int typeIdd)
{
    return new Blog(name, title, typeIdd);
}
