如何在ASP.NET Core Web API中传递int数组 [英] How to pass an array of int in ASP.NET Core Web API

问题描述

我有这个Web API方法:

I have this Web API method:

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery]int[] childrenIds)
    {
        // omitted for brevity
    }
}

我正在尝试通过Ajax传入查询字符串来调用它，但是我似乎无法使其正常工作.我的Ajax呼叫看起来像这样:

I'm trying to call this via Ajax passing in an query string but I can't seem to get it to work. My Ajax call looks like this:

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

该方法被调用，但是不会填充int数组.我在做什么错了?

The method is called but it the int array does not get populated. What am I doing wrong?

推荐答案

尝试将Name添加到[FromQuery]，因此代码应如下所示:

Try add Name to [FromQuery], so the code should look like this:

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery(Name="childrenIds")]int[] childrenIds)
    {
        // omitted for brevity
    }
}

以及像这样的ajax网址:

and ajax url like this:

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})
