项目中需要做一个短信引擎，将信息验证码推送到短信平台，然后使用第三方短信平台发短信的功能，这是网上找到一个简单的实例，从中了解一二：

本程序是通过使用中国网建提供的SMS短信平台实现的（该平台目前为注册用户提供5条免费短信，3条免费彩信，这足够用于我们测试用了。在使用前需要注册，注册地址为下面是程序源码：

/**
 * @Date 2012-9-18
 */
package com.xxx.mail;

import java.io.IOException;

import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

public class SendMsg_webchinese {
    /**
     * @date Sep 18, 2012
     * @time 9:38:25 AM
     * @param args
     * @throws IOException
     * @throws HttpException
     * @description
     */
    public static void main(String[] args) throws HttpException, IOException {
        HttpClient client = new HttpClient();
        PostMethod post = new PostMethod("http://gbk.sms.webchinese.cn");
        // PostMethod post = new PostMethod("http://sms.webchinese.cn/web_api/");
        post.addRequestHeader("Content-Type",   "application/x-www-form-urlencoded; charset=gbk");
        // 在头文件中设置转码
        NameValuePair[] data = { new NameValuePair("Uid", "dengsilinming"),// 注册的用户名
                new NameValuePair("Key", "72da78da5ff54f450505"),// 注册成功后，登录网站后得到的密钥
                new NameValuePair("smsMob", "12345678900"),// 手机号码
                new NameValuePair("smsText", "这是专用于测试的信息，能否正常发短信呢？") };// 短信内容
        post.setRequestBody(data);

        client.executeMethod(post);
        Header[] headers = post.getResponseHeaders();
        int statusCode = post.getStatusCode();
        System.out.println("statusCode:" + statusCode);
        for (Header h : headers) {
            System.out.println("---" + h.toString());
        }
        String result = new String(post.getResponseBodyAsString().getBytes("gbk"));
        System.out.println(result);
    }
}

需要用到的jar包共三个： 
commons-logging-1.1.1.jar 
commons-httpclient-3.1.jar 
commons-codec-1.4.jar

以下内容摘自中国建网SMS短信通API ：

提示:HTTP调用URL接口时, 参数值必须URL编码后再调用 参数变量 说明 
Gbk编码Url 

  • http://gbk.sms.webchinese.cn/Utf-8编码Url http://utf8.sms.webchinese.cn/Uid 本站用户名（如您无本站用户名请先注册） 
    Key 注册时填写的接口安全密码（可到用户平台修改安全密码 是注册网站的密钥，非用户密码） 
    smsMob 目的手机号码（多个手机号请用半角逗号隔开） 
    smsText 短信内容，最多支持300个字，普通短信70个字/条，长短信64个字/条计费 
    多个手机号请用半角,隔开，如：13888888886,13888888887,1388888888 一次最多对50个手机发送 
    短信内容支持长短信，最多300个字，普通短信70个字/条，长短信64个字/条计费 短信发送后返回值 说明
  • -1 没有该用户账户
  • -2 密钥不正确（不是用户密码）
  • -3 短信数量不足
  • -11 该用户被禁用
  • -14 短信内容出现非法字符
  • -4 手机号格式不正确
  • -41 手机号码为空
  • -42 短信内容为空
  • 大于0 短信发送数量 
    下面是不同的语言调用SMS接口的简单demo：

1.JAVA调用

import java.io.UnsupportedEncodingException;
import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;

public class SendMsg_webchinese {

    public static void main(String[] args)throws Exception
    {

        HttpClient client = new HttpClient();
        PostMethod post = new PostMethod("http://gbk.sms.webchinese.cn"); 
        post.addRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=gbk");
        //在头文件中设置转码
        NameValuePair[] data ={ 
            new NameValuePair("Uid", "本站用户名"),
            new NameValuePair("smsMob","手机号码"),
            new NameValuePair("smsText","短信内容")
            };
        post.setRequestBody(data);

        client.executeMethod(post);
        Header[] headers = post.getResponseHeaders();
        int statusCode = post.getStatusCode();
        System.out.println( "statusCode:"+statusCode );
        for(Header h : headers)
        {
            System.out.println(h.toString());
        }
        String result = new String(post.getResponseBodyAsString().getBytes("gbk")); 
        System.out.println(result);

        post.releaseConnection();

    }
}

jar包下载 

commons-logging-1.1.1.jar 
commons-httpclient-3.1.jar 
commons-codec-1.4.jar

2. ASP 调用例子 
<% 
‘常用函数 
‘输入url目标网页地址，返回值getHTTPPage是目标网页的html代码 

function getHTTPPage(url) 
dim Http 
set Http=server.createobject(“MSXML2.XMLHTTP”) 
Http.open “GET”,url,false 
Http.send() 
if Http.readystate<>4 then 
exit function 
end if 
getHTTPPage=bytesToBSTR(Http.responseBody,”GB2312”) 
set http=nothing 
if err.number<>0 then err.Clear 
end function 
Function BytesToBstr(body,Cset) 
dim objstream 
set objstream = Server.CreateObject(“adodb.stream”) 
objstream.Type = 1 
objstream.Mode =3 
objstream.Open 
objstream.Write body 
objstream.Position = 0 
objstream.Type = 2 
objstream.Charset = Cset 
BytesToBstr = objstream.ReadText 
objstream.Close 
set objstream = nothing 
End Function

‘自已组合一下提交的URL加入自己的账号和密码 

sms_url=”http://sms.webchinese.cn/web_api/?Uid=账号&Key=接口密钥&smsMob=手机号码&smsText=短信内容” 
response.write getHTTPPage(sms_url) 
%>

3.C# 调用

//需要用到的命名空间 
using System.Net; 
using System.IO; 
using System.Text; 
//调用时只需要把拼成的URL传给该函数即可。判断返回值即可 
public string GetHtmlFromUrl(string url) 
{ 
string strRet = null;if(url==null || url.Trim().ToString()==”“) 
{ 
return strRet; 
} 
string targeturl = url.Trim().ToString(); 
try 
{ 
HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(targeturl); 
hr.UserAgent = “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)”; 
hr.Method = “GET”; 
hr.Timeout = 30 * 60 * 1000; 
WebResponse hs = hr.GetResponse(); 
Stream sr = hs.GetResponseStream(); 
StreamReader ser = new StreamReader(sr, Encoding.Default); 
strRet = ser.ReadToEnd(); 
} 
catch (Exception ex) 
{ 
strRet = null; 
} 
return strRet; 
}

4.PHP

$url='http://sms.webchinese.cn/web_api/?Uid=账号&Key=接口密钥&smsMob=手机号码&smsText=短信内容';

echo Get($url);
function Get($url)
{
if(function_exists('file_get_contents'))
{
$file_contents = file_get_contents($url);
}
else
{
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
}
return $file_contents;
}

5.VB.NET

'调用发送短信,NoList接收号码.多个之间用,分开,Memo内容70字
Public Function SendSMS(ByVal NoList As String, ByVal Memo As String) As String 
Dim Url As String =
"http://sms.webchinese.cn/web_api/?Uid=账号&Key=接口密钥&smsMob=手机号码&smsText=短信内容"
Dim webClient As New Net.WebClient()
Try
'Dim responseData As Byte() = 
Dim srcString As String = webClient.DownloadString(Url)
Return srcString
Catch
Return "-444"
End Try

经过测试上面java源码是能够发送成功的，其它语言的没有测试。如果大家有更好的发送短信的方法请告之，谢谢！
