Javascript对象传递给ASP.NET Handler

Question

如何将JavaScript对象传递给ASP.NET Handler并解析值？

我创建了一个复杂类型对象,如:

function AccountObjCreate() {
var AccountsView = {};
AccountsView.Username = null;
AccountsView.Email = null;
AccountsView.Password = null;

return AccountsView;
}

并填写该对象,如:

var aView = AccountObjCreate();
aView.Username = $('#tbUserName').val().trim();
aView.Email = $('#tbEmail').val().trim().toLowerCase();
aView.Password = $('#tbPassword').val().trim();

然后我打电话给:

$.post("/Handlers/AccountHandler.ashx", { obj: aView },
        function (results) {
            if (results.isSuccess) {
                alert(results.msg);
            } else {
                alert(results.msg);
            }
        }, "json");

当我在控制台中查看它时,我将aView中的所有数据视为json.

我的ASP.NET处理程序页面是

context.Response.ContentType = "application/json";
context.Response.ContentEncoding = Encoding.UTF8;
string obj = context.Request["obj"];

但是obj是NULL.

为了通过你应该序列化到一个字符串的服务器来获取对象(可以使用所描述的方法在这里或包括JSON JavaScript库在这里),然后使用.NET反序列化JavaScriptSerializer类.

JS代码.

var data = {
    obj: JSON.stringify(aView)
};
$.post("/Handlers/AccountHandler.ashx", data, function(results) {
    if (results.isSuccess) {
        alert(results.msg);
    } else {
        alert(results.msg);
    }
}, "json");?

然后在服务器处理程序上,您可以使用提到的JavaScriptSerializer类解析JSON字符串.

public class AccountsView {
    public string Username;
    public string Email;
    public string Password;
}

public void ProcessRequest(HttpContext context)
{
    JavaScriptSerializer serializer = new JavaScriptSerializer();
    string value = context.Request["obj"];
    var aView = serializer.Deserialize(value, typeof(AccountsView));

    context.Response.ContentType = "application/json";
    context.Response.ContentEncoding = Encoding.UTF8;
}
