在 ASP.NET 中从 AJAX 读取 JSON

问：

我尝试发送到我的 JSON 文件有问题 ASP.NET

我想读取文件，输出它，并在以后相应地过滤其他函数。

我的脚本看起来像这样：

<script>

var NetworkValues = JSON.parse(localStorage.getItem("NetworkValues"));
var arpValues = JSON.parse(localStorage.getItem("arpValues"));
var addrValues = JSON.parse(localStorage.getItem("addrValues"));
var fsckValues = JSON.parse(localStorage.getItem("fsckValues"));
var vmstatValues = JSON.parse(localStorage.getItem("vmstatValues"));
var freeValues = JSON.parse(localStorage.getItem("freeValues"));
var ServiceValues = JSON.parse(localStorage.getItem("ServiceValues"));
var ProcessValues = JSON.parse(localStorage.getItem("ProcessValues"));
var topValues = JSON.parse(localStorage.getItem("topValues"));
var PortValues = JSON.parse(localStorage.getItem("PortValues"));

function sendValues()
    {var NetworkOutput = NetworkValues;
var arpOutput = arpValues;
var addrOutput = addrValues;
var fsckOutput = fsckValues;
var vmstatOutput = vmstatValues;
var freeOutput = freeValues;
var serviceOutput = ServiceValues;
var processOutput = ProcessValues;
var topOutput = topValues;
var PortOutput = PortValues;

var message = document.getElementById('message');

    $.ajax({
        type: "POST",
        url: "api/FilterSubmit",
        data: 
        {
        NetworkOutput: NetworkOutput,
        arpOutput: arpOutput,
        addrOutput: addrOutput,
        fsckOutput: fsckOutput,
        vmstatOutput: vmstatOutput,
        freeOutput: freeOutput,
        serviceOutput: serviceOutput,
        processOutput: processOutput,
        topOutput: topOutput,
        PortOutput : PortOutput
        },
    success: function(result) 
        {
            message.innerHTML = 'success!' 
            console.log(NetworkOutput)   
            console.log(arpOutput) 
            console.log(addrOutput)   
            console.log(fsckOutput)  
            console.log(vmstatOutput)  
            console.log(freeOutput) 
            console.log(processOutput)
            console.log(serviceOutput)
            console.log(topOutput)
            console.log(PortOutput)
                                                       
        },
        error: function(err) 
        {
       message.innerHTML = 'failed!'
        }
    })
    }  

我在控制器内部尝试了什么：（来源：https://www.stevejgordon.co.uk/sending-and-receiving-json-using-httpclient-with-system-net-http-json）

        public IActionResult ButtonClickSub()
        {
            static async Task<FilteredScripts> GetJsonHttpClient(string uri, HttpClient httpClient)
            {
                try
                {
                    return await httpClient.GetFromJsonAsync<FilteredScripts>(uri);
                }
                catch (HttpRequestException) // Non success
                {
                    Console.WriteLine("An error occurred.");
                }
                catch (NotSupportedException) // When content type is not valid
                {

                }


                return null;
            }
            return Ok();
        }
    }
}

private static async Task<User> GetJsonFromContent(string uri, HttpClient httpClient)
{
    var request = new HttpRequestMessage(HttpMethod.Get, uri);
    request.Headers.TryAddWithoutValidation("some-header", "some-value");

    using var response = await httpClient.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);

    if (response.IsSuccessStatusCode)
    {
        // perhaps check some headers before deserialising

        try
        {
            return await response.Content.ReadFromJsonAsync<User>();
        }
        catch (NotSupportedException) // When content type is not valid
        {
            Console.WriteLine("The content type is not supported.");
        }
        catch (JsonException) // Invalid JSON
        {
            Console.WriteLine("Invalid JSON.");
        }
    }

    return null;
}
