1、先注册账号，一定要填写好签名格式。不填会返回-51错误。   代码信息接口详细==》http://sms.webchinese.cn/api.shtml   。

2、测试代码

package sms;

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_001 {

public static void main(String[] args) throws Exception {
HttpClient client = new HttpClient();
// http://gbk.api.smschinese.cn/?Uid=本站用户名&Key=接口安全秘钥&smsMob=手机号码&smsText=验证码:8888
PostMethod post = new PostMethod("http://gbk.api.smschinese.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", "ybbwxz"),
new NameValuePair("Key", "cdbcf3df444980e9cb12"), //sms短信秘钥
new NameValuePair("smsMob", "173xxxx0975"),
new NameValuePair("smsText", "杨彬彬") };//短息内容
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); // 打印返回消息状态 1代表成功 //返回其他状态请查阅文档

post.releaseConnection();

}

}

3、发送结果
