Question

我正在尝试将Json数据从html页面发布到ASP页面并在函数中接收它。像这样：

        address1 = [["123  Main St", "", "MESA", "AZ", ""],
        ["5088 n  desert ln", "", "PRESCOTT VALLEY", "AZ", "86314"]];
        address1 = JSON.stringify(address1);


        $.ajax({

            url: "Default2.aspx/GetPostData",
            type: "post",
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            data: '{"address1":"' + address1 + '"}',
            traditional : true,
            success: function (data2) {
                alert("success::" + data2.d);

            },
            error: function (response) {
                alert("ERROR:::" + response.d);
            }
        });

并在asp页面中的以下函数中接收它

[System.Web.Services.WebMethod]
public static string GetPostData(String address1)
{
          ------
}

但是数据没有以json格式接收它是作为文本接收的如图所示

123 Main St ,, MESA，AZ ,, 5088 n desert ln ,, PRESCOTT VALLEY，AZ，86314

我想只收到json ..

请说明我在做什么错误。

Answer 1

如果更改函数签名以使用对象，则可以使用JsonConvert将此对象转换为C＃模型。我正在处理的ASP.NET应用程序中的一些示例代码：

[Route("api/inviteuser/{model}")]
[HttpPut]
public HttpResponseMessage InviteUser(Object model)
{
    var jsonString = model.ToString();

    InviteUserModel result = JsonConvert.DeserializeObject<InviteUserModel>(jsonString);

}

InviteUserModel是一个简单的C＃对象：

public class InviteUserModel
{
    public string EmailAddress { get; set; }
    public string Message { get; set; }
    public long CurrentCompId { get; set; }
}

我在这里发现了两个问题：

1-在Ajax调用中，json无效。改为。还可以使您的地址元素更加标准化。

var address1 = [{＆＃34; Street1＆＃34;：＆＃34; 123 Main St＆＃34;，＆＃34; Street2＆＃34;：＆＃34;＆＃34;，＆＃34; City＆＃34;：＆＃34; MESA＆＃34;，＆＃34; State＆＃34;：＆＃34; AZ＆＃34;，＆＃34; Zip＆＃34;：＆＃34;＆＃34; }， {＆＃34; Street1＆＃34;：＆＃34; 5088 n desert ln＆＃34;，＆＃34; Street2＆＃34;：＆＃34;＆＃34;，＆＃34; City＆＃34;：＆＃34; PRESCOTT VALLEY＆＃34;，＆＃34; State＆＃34;：＆＃34; AZ＆＃34;，＆＃34; Zip＆＃34;：＆＃34; 86314＆＃34; }];

$。AJAX（{

            url: "http://localhost:63850/Default.aspx/GetPostData",
            type: "post",
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            data: '{"address1":' + address1 + '}',

            //'{"address1":"' + address1 + '"}',
            traditional: true,
            success: function (data2) {
                alert("success::" + data2.d);

            },
            error: function (response) {
                alert("ERROR:::" + response.d);
            }
        });

2- web meothod参数是字符串，而address1作为数组传递。

Asp.NET为此抛出了这个错误。 {＆＃34;消息＆＃34;：＆＃34;类型\ u0027System.String \ u0027不支持反序列化数组...

创建地址容器类并将Web方法参数设置为List：

   public class Address
    {
        public string Street1 { get; set; }
        public string Street2 { get; set; }
        public string City { get; set; }
        public string State { get; set; }
        public string PostCode { get; set; }
    }

    [System.Web.Services.WebMethod]
    public static string GetPostData(List<Address> addresses)
    {
        // addresses[0].Street1;
        // addresses[0].City;
        return null;
    }

3-如果您不想更改地址javascript数组。

    [System.Web.Services.WebMethod]
    public static string GetPostData(object address1)
    {
        List<string[]> list = new List<string[]>();

        string[][] addresses = new string[2][];

        foreach (var addressList in address1 as object[])
        {
            string[] addressElement = new string[5];
            int index = 0;
            foreach (var temp in addressList as object[])
            {
                addressElement[index++] = (temp != null) ? temp.ToString() : string.Empty;
            }
            list.Add(addressElement);
        }

        return null;
    }

以Json格式接收JSON数据发布到ASP页面
