c# 生成json数据包
json数据类型，归根到底就是一个字符串，管他里面什么格式，它就是一个字符串来的！
看一个json数据包：
{
"touser":"OPENID",
"template_id":"ngqIpbwh8bUfcSsECmogfXcV14J0tQlEpBO27izEYtY",
"url":"http://weixin.qq.com/download",
"topcolor":"#FF0000",
"data":
{
"User": {
"value":"黄先生",
"color":"#173177"
},
"Date":{
"value":"06月07日 19时24分",
"color":"#173177"
},
"CardNumber":{
"value":"0426",
"color":"#173177"
},
"Type":{
"value":"消费",
"color":"#173177"
},
"Money":{
"value":"人民币260.00元",
"color":"#173177"
},
"DeadTime":{
"value":"06月07日19时24分",
"color":"#173177"
},
"Left":{
"value":"6504.09",
"color":"#173177"
}
}
}
你可以直接赋值一个string对象：
string json = "{\"touser\":\"OPENID\",.......}";
遇到双引号要使用转义“\”进行转义。这样弄出来的一个string对象就是一个json数据包了。
这样直接赋值麻烦，在网上找了找，为了生成上面这样的json，弄到了下面几个类：
PayTemplateHeader.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
namespace tenpay
{
[DataContract]
public class PayTemplateHeader
{
public PayTemplateHeader() { }
public PayTemplateHeader(string template_id, string touser, string url)
{
this.template_id = template_id;
this.touser = touser;
this.url = url;
}
/// <summary>
/// 模板ID
/// </summary>
[DataMember]
public string template_id { get; set; }
/// <summary>
/// 微信接收信息用户的openid
/// </summary>
[DataMember]
public string touser { get; set; }
/// <summary>
/// 信息点击链接
/// </summary>
[DataMember]
public string url { get; set; }
}
}
PayTemplate.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.Serialization;
namespace tenpay
{
/// <summary>
/// 微信充值模板接口请求实体对象
/// </summary>
[DataContract]
public class PayTemplate
{
public PayTemplate() { }
/// <summary>
/// 您好，您已成功进行某游戏币充值。
/// </summary>
[DataMember]
public string first { get; set; }
/// <summary>
/// 帐号：kantzou
/// </summary>
[DataMember]
public string accountType { get; set; }
/// <summary>
/// 帐号：kantzou
/// </summary>
[DataMember]
public string account { get; set; }
/// <summary>
/// 获得游戏币：500点
/// </summary>
[DataMember]
public string productType { get; set; }
/// <summary>
/// 获得游戏币：500点
/// </summary>
[DataMember]
public string number { get; set; }
/// <summary>
/// 充值金额：50元
/// </summary>
[DataMember]
public string amount { get; set; }
/// <summary>
/// 充值状态：充值成功
/// </summary>
[DataMember]
public string result { get; set; }
/// <summary>
/// 祝您游戏愉快。
/// </summary>
[DataMember]
public string remark { get; set; }
}
}
JSONHelper.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace tenpay
{
/// <summary>
/// json转化类
/// </summary>
[Serializable]
public class JSONHelper
{
public static string Serialize<T>(T obj)
{
System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());
MemoryStream ms = new MemoryStream();
serializer.WriteObject(ms, obj);
string retVal = Encoding.UTF8.GetString(ms.ToArray());
ms.Dispose();
return retVal;
}
public static T Deserialize<T>(string json)
{
T obj = Activator.CreateInstance<T>();
MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());
obj = (T)serializer.ReadObject(ms);
ms.Close();
ms.Dispose();
return obj;
}
}
}
public class DataFormat
{
public string value { get; set; }
public string color { get; set; }
}
public class DataFormatList
{
public List<DataFormat> first { get; set; }
public List<DataFormat> accountType { get; set; }
public List<DataFormat> account { get; set; }
public List<DataFormat> productType { get; set; }
public List<DataFormat> number { get; set; }
public List<DataFormat> amount { get; set; }
public List<DataFormat> result { get; set; }
public List<DataFormat> remark { get; set; }
}
/// <summary>
/// 微信充值模板接口json参数整理
/// </summary>
/// <param name="PayTemplate">微信充值模板接口参数实例</param>
/// <returns></returns>
public string getPayTemplateJson(PayTemplateHeader header, PayTemplate template,string color)
{
string jsonH = JSONHelper.Serialize<PayTemplateHeader>(header);
DataFormatList dataformatlist = new DataFormatList();
dataformatlist.first = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.first),color=color}};
dataformatlist.accountType = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.accountType),color=color}};
dataformatlist.account = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.account),color=color}};
dataformatlist.productType = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.productType),color=color}};
dataformatlist.number = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.number),color=color}};
dataformatlist.amount = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.amount),color=color}};
dataformatlist.result = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.result),color=color}};
dataformatlist.remark = new List<DataFormat>(){
new DataFormat(){value=ConvertGBK(template.remark),color=color}};
string jsonD = new JavaScriptSerializer().Serialize(dataformatlist);
string json = jsonH.Insert(jsonH.Length - 1, ",\"data\":" + jsonD.Replace("[", "").Replace("]", ""));
return json;
}
private string ConvertGBK(string p)
{
byte[] byteArray = Encoding.UTF8.GetBytes(p);
return Encoding.GetEncoding("GBK").GetString(byteArray);
}
调用例子：
PayTemplateHeader header = new PayTemplateHeader();
header.template_id = "jrciIIcHIYLJujC7FyqSiKyGGWnLok6VQJ1a81p1HLw";
header.touser = "openid123";
header.url = "http://www.baidu.com/App/Pay/1.aspx";
PayTemplate paytemplate = new PayTemplate();
paytemplate.first = "您好，您已成功进行某游戏币充值。";
paytemplate.accountType = "账号";
paytemplate.account = "k6780384";
paytemplate.productType = "游戏币";
paytemplate.number = "500点";
paytemplate.amount = "50元";
paytemplate.result = "充值成功";
paytemplate.remark = "祝您游戏愉快";
TenpayUtil tenpay = new TenpayUtil();
string post_data = tenpay.getPayTemplateJson(header, paytemplate, "#173177");
Response.Write(post_data);
输出：
哎，乱码了，不管了，只要微信那边不是乱码就好。
