问题描述

我有一个客户创建 JSON对象，它有如下值：

<$p$p><$c$c>{"Title":"Mr","FirstName":"S","LastName":"J","Birthday":"01/01/2011","Address":[{"Line1":"Line1","Line2":"Line2","City":"City","State":"State","Zip":"00000","County":"0000"},{"Line1":"Line11","Line2":"Line21","City":"City1","State":"State1","Zip":"11111","County":"1111"}],"Email":[{"Email":"[e-mail]","EmailType":"Personal"},{"Email":"[e-mail]","EmailType":"Work"}],"Phone":[{"Phone":"1231231234","PhoneType":"Mobile"},{"Phone":"1231232345","PhoneType":"Work"}]}

我需要在处理程序中该数据/ CustomerHandler.ashx做一些数据库操作。 我的AJAX调用如下：

  $。阿贾克斯（{
        键入：POST，
        的contentType：应用/ JSON的;字符集= UTF-8，
        网址：处理程序/ CustomerHandler.ashx
        数据：客户，
        数据类型：JSON，
        成功：insertCustomerCallback
    }）;
 

昏暗customerJSON的String = HttpContext.Current.Request.Form（客户）显示为空。

解决方案

您可以发送客户为使用JSON.stringify方法从的 json2.js ：

  VAR的客户= {标题：先生，姓：S，姓氏：J，生日：01/01/2011 ，地址：[{1号线：1号线，2号线：2号线，城市：城市，国家：国家，邮编：00000，县：0000}，{线路1：Line11，2号线：Line21，城市：City1，国家：状态1，邮编：11111，县：1111}]，电子邮件：[{电子邮件：[e-mail]，EmailType：个人}，{电子邮件：[e-mail] EmailType：工作}]，手机：[{手机：1231231234，PhoneType：手机}，{手机：1231232345，PhoneType：工作} ]};
$阿贾克斯（{
    键入：POST，
    的contentType：应用/ JSON的;字符集= UTF-8，
    网址：处理程序/ CustomerHandler.ashx
    数据：JSON.stringify（客户），
    数据类型：JSON，
    成功：函数（结果）{

    }
}）;
 

和在通用处理器从请求流中读取它：

 暗淡客户=新的字节（context.Request.InputStream.Length  -  1）{}
context.Request.InputStream.Read（客户，0，customer.Length）
昏暗customerJSON = Encoding.UTF8.GetString（客户）
// TODO：反序列化JSON回Customer对象
 

正如你可以使用脚本替代启用的WebMethod

I have a Customer JSON object created which has value as below:

{"Title":"Mr","FirstName":"S","LastName":"J","Birthday":"01/01/2011","Address":[{"Line1":"Line1","Line2":"Line2","City":"City","State":"State","Zip":"00000","County":"0000"},{"Line1":"Line11","Line2":"Line21","City":"City1","State":"State1","Zip":"11111","County":"1111"}],"Email":[{"Email":"[e-mail]","EmailType":"Personal"},{"Email":"[e-mail]","EmailType":"Work"}],"Phone":[{"Phone":"1231231234","PhoneType":"Mobile"},{"Phone":"1231232345","PhoneType":"Work"}]}

I need to get this data in the Handlers/CustomerHandler.ashx to do some DB operations. My AJAX call is as follows:

  $.ajax({
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "Handlers/CustomerHandler.ashx",
        data: Customer,
        dataType: "json",
        success: insertCustomerCallback
    });

Dim customerJSON As String = HttpContext.Current.Request.Form("Customer")is shown as empty.

解决方案

You might send the customer as a JSON object using the JSON.stringify method from json2.js:

var Customer = { "Title": "Mr", "FirstName": "S", "LastName": "J", "Birthday": "01/01/2011", "Address": [{ "Line1": "Line1", "Line2": "Line2", "City": "City", "State": "State", "Zip": "00000", "County": "0000" }, { "Line1": "Line11", "Line2": "Line21", "City": "City1", "State": "State1", "Zip": "11111", "County": "1111"}], "Email": [{ "Email": "[e-mail]", "EmailType": "Personal" }, { "Email": "[e-mail]", "EmailType": "Work"}], "Phone": [{ "Phone": "1231231234", "PhoneType": "Mobile" }, { "Phone": "1231232345", "PhoneType": "Work"}] };
$.ajax({
    type: "POST",
    contentType: "application/json; charset=utf-8",
    url: "Handlers/CustomerHandler.ashx",
    data: JSON.stringify(Customer),
    dataType: "json",
    success: function (result) {

    }
});

and on the generic handler read it from the request stream:

Dim customer = New Byte(context.Request.InputStream.Length - 1) {}
context.Request.InputStream.Read(customer, 0, customer.Length)
Dim customerJSON = Encoding.UTF8.GetString(customer)
// TODO: deserialize the JSON back to a Customer object

As an alternative you could use a script enabled WebMethod.
