从json响应中获取数据。 [英] Get data from json response.

问题描述

大家好，

我需要从给定的json响应中检索id等事务详细信息。

Hi all,
I need to retrieve the transaction details like id from given json response.

{
  "id": "PAY-85619955UR925572LKJLINZY",
  "create_time": "2013-10-10T10:52:23Z",
  "update_time": "2013-10-10T10:52:59Z",
  "intent": "sale",
  "payer": {
    "payment_method": "paypal",
    "payer_info": {
      "email": "[e-mail]",
      "first_name": "Sujeet",
      "last_name": "Singh",
      "payer_id": "HCN5UA7K9PPJJ"
    }
  },
  "transactions": [
    {
      "amount": {
        "currency": "USD",
        "total": "2345.00",
        "details": {
          "subtotal": "2345.00"
        }
      },
      "description": "Transaction description.",
      "related_resources": [
        {
          "sale": {
            "id": "57J06778HJ9237740",
            "create_time": "2013-10-10T10:52:23Z",

              "currency": "USD",
              "total": "2345.00"
            },
            "state": "pending",
            "parent_payment": "PAY-85619955UR925572LKJLINZY",
            "links": [
              {
                "href": "https://api.sandbox.paypal.com/v1/payments/sale/57J06778HJ9237740",
                "rel": "self",
                "method": "GET"
              },
              {
                "href": "https://api.sandbox.paypal.com/v1/payments/sale/57J06778HJ9237740/refund",
                "rel": "refund",
                "method": "POST"
              },
              {
                "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-85619955UR925572LKJLINZY",
                "rel": "parent_payment",
                "method": "GET"
              }
            ]
          }
        }
      ]
    }
  ],
  "state": "pending",
  "links": [
    {
      "href": "https://api.sandbox.paypal.com/v1/payments/payment/PAY-85619955UR925572LKJLINZY",
      "rel": "self",
      "method": "GET"
    }
  ]
}

这是我得到json的字符串。



String json =（String ）CurrContext.Items [ResponseJson];



任何帮助都会真正贬值。

谢谢

And this is the string where i am getting json.

String json = (String)CurrContext.Items["ResponseJson"];

Any help will really apreciated.
Thanks

推荐答案

您可以使用 DataContract 序列化技术将 JSON 序列化和反序列化为编程对象。



你必须构造一个适当的类来反序列化。以下主题应该有所帮助。

You can serialise and de-serialise JSON to programming objects using DataContract serialisation techniques.

You have to construct an appropriate class to de-serialise to. The following topics should help.

谢谢大家。我自己解决了这个问题。这是代码...



CS： -



CurrContext.Items.Add（ ResponseJson，JObject.Parse（executedPayment.ConvertToJson（））。ToString（Formatting.Indented））;

String json =（String）CurrContext.Items [ResponseJson];

hdnPassValue.Value = json;

Page.ClientScript.RegisterStartupScript（this.GetType（），alert，initialize（）;，true）;



JQuery： -

函数initialize（）{

var jsO =

Thank you all. I have solve this myself. And this is the code...

CS:-

CurrContext.Items.Add("ResponseJson", JObject.Parse(executedPayment.ConvertToJson()).ToString(Formatting.Indented));
String json = (String)CurrContext.Items["ResponseJson"];
hdnPassValue.Value = json;
Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "initialize();", true);

JQuery:-
function initialize() {
var jsO =

（＃ <％= hdnPassValue.ClientID％>）。val（）;

var obj = eval（'（'+ jsO +'）'）;

var tId = obj.transactions [0] .related_resources [0] .sale.id;

alert（tId）;

}

("#<%=hdnPassValue.ClientID%>").val();
var obj = eval('(' + jsO + ')');
var tId=obj.transactions[0].related_resources[0].sale.id;
alert(tId);
}
