将数组传递给asp net core web api action方法HttpGet [英] passing an array to a asp net core web api action method HttpGet

问题描述

我正在尝试向我的操作方法发送一个整数数组，代码如下所示:

I am trying to send an array of integers to my action method the code looks like so:

[HttpGet]
    public async Task<IActionResult> ServicesByCategoryIds([FromQuery] int[] ids)
    {
        var services = await _accountsUow.GetServiceProfilesByCategoryIdsAsync(ids);
        return Ok(services);
    }

我这样调用方法:https://localhost:44343/api/accounts/servicesbycategoryids?ids=1&ids=2

但是当我调用这个方法时总是得到一个空数组，即使我在查询字符串中传递了 id.我正在使用 .net 核心 2.1.

but always get en empty array when I call this method even tho I pass the ids in the query string. I am using .net core 2.1.

我在谷歌上搜索的所有内容都表明这实际上就是这样做的方式...有什么我在这里遗漏的吗?

everything I have googled suggests that this is in fact the way this is done. . . is there something I am missing here?

谢谢！

推荐答案

Binding failed for Array parameter is a known issue under Asp.Net Core 2.1 已记录查询字符串中的数组或列表未解析#7712.

Binding failed for Array parameter is a known issue under Asp.Net Core 2.1 which has been recorded Array or List in query string does not get parsed #7712.

对于临时解决方法，您可以像下面这样设置 FromQuery Name Property:

For a tempory workaround, you could set the FromQuery Name Property like below:

        [HttpGet()]
    [Route("ServicesByCategoryIds")]
    public async Task<IActionResult> ServicesByCategoryIds([FromQuery(Name = "ids")]int[] ids)
    {            
        return Ok();
    }
