首先建立jsonObject，当然你也可以使用xml解析，目前介绍一下我使用的方法。

然后是调用地址 和方法
[csharp] view plaincopyprint?
public int validateNumber(string mobileNo)
{

string result = CommonTools.httpPostByUrl(url, paramsString);
if (!result.Equals(""))
{
JsonObject resultJson = new JsonObject(result);
if (resultJson.Properties<string>("QueryResult").Equals("True") && resultJson.Properties<string>("Province").Equals("江西"))
{
//成功返回0
return 0;
}
else if (result.Equals(""))
{
return 1;
}
//失败返回1
}
return 1;
}
[csharp] view plaincopyprint?
/// <summary>
/// 调用httpPost接口
/// </summary>
/// <param name="url"></param>
/// <param name="paramsString"></param>
/// <returns></returns>
public static string httpPostByUrl(string url, string paramsString)
{
try
{
using (var client = new ExtendedWebClient())
{
client.Timeout = 3000;
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
byte[] postData = Encoding.ASCII.GetBytes(paramsString);
byte[] responseData = client.UploadData(url, "POST", postData);
string result = Encoding.UTF8.GetString(responseData);
Console.WriteLine("httpPost result:" + result);
return result;
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
return "";
}
}
扩展的webCilent
[csharp] view plaincopyprint?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
namespace QinQinGo.Common
{
public class ExtendedWebClient : WebClient
{
public int Timeout { get; set; }
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request != null)
request.Timeout = Timeout;
return request;
}
public ExtendedWebClient()
{
Timeout = 100000; // the standard HTTP Request Timeout default
}
}
}

然后是调用地址 和方法
[csharp] view plaincopyprint?
public int validateNumber(string mobileNo)
{
string url = ServiceConfig.serviceUrl["validateNumber"].ToString();
string paramsString = "m=" + mobileNo + "&output=json";
string result = CommonTools.httpPostByUrl(url, paramsString);
if (!result.Equals(""))
{
JsonObject resultJson = new JsonObject(result);
if (resultJson.Properties<string>("QueryResult").Equals("True") && resultJson.Properties<string>("Province").Equals("江西"))
{
//成功返回0
return 0;
}
else if (result.Equals(""))
{
return 1;
}
//失败返回1
}
return 1;
}
[csharp] view plaincopyprint?
/// <summary>
/// 调用httpPost接口
/// </summary>
/// <param name="url"></param>
/// <param name="paramsString"></param>
/// <returns></returns>
public static string httpPostByUrl(string url, string paramsString)
{
try
{
using (var client = new ExtendedWebClient())
{
client.Timeout = 3000;
client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
byte[] postData = Encoding.ASCII.GetBytes(paramsString);
byte[] responseData = client.UploadData(url, "POST", postData);
string result = Encoding.UTF8.GetString(responseData);
Console.WriteLine("httpPost result:" + result);
return result;
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
return "";
}
}
扩展的webCilent
[csharp] view plaincopyprint?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
namespace QinQinGo.Common
{
public class ExtendedWebClient : WebClient
{
public int Timeout { get; set; }
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request != null)
request.Timeout = Timeout;
return request;
}
public ExtendedWebClient()
{
Timeout = 100000; // the standard HTTP Request Timeout default
}
}
}
