java 短信平台接口_Java 通过Http请求对接第三方短信平台接口

今天在项目中接到一个小任务要对接第三方短信平台开发，这个之前就写过，正在想拿之前的代码来看时，发现找不到了，索性果断写了一个，并在此记录下来。

/**

public class TestHttpClient {

public static void main(String[] args) {

doPost();

}

public static void doPost(){

String url = "http://test:80/ApiService.asmx/Send?";

String account = "test";

String pwd = "test";

String product = "test";

String phoneNumber = "test";

String content = "测试短信内容";

StringBuilder builder = new StringBuilder(url);

builder.append("account="+account + "&");//添加账号

builder.append("pwd="+pwd + "&");//添加密码

builder.append("product="+product + "&");//添加产品号

builder.append("mobile="+phoneNumber +"&");//添加手机号码

builder.append("message="+content);

URL localURL = null;

URLConnection connection = null;

HttpURLConnection httpURLConnection = null;

InputStream inputStream = null;

try {

localURL = new URL(builder.toString());

connection = localURL.openConnection();

httpURLConnection = (HttpURLConnection)connection;

httpURLConnection.setDoOutput(true);

httpURLConnection.setRequestMethod("GET");

String result = null;

inputStream = httpURLConnection.getInputStream();

result = convertStreamToString(inputStream);

String resultCode = parseResult(result);

} catch (Exception e) {

e.printStackTrace();

}

}

/**

* 拼接请求参数

* @param parameterMap

* @return

*/

public static String translateParams(Map parameterMap){

StringBuffer parameterBuffer = new StringBuffer();

if (parameterMap != null) {

Iterator iterator = parameterMap.keySet().iterator();

String key = null;

String value = null;

while (iterator.hasNext()) {

key = (String)iterator.next();

if (parameterMap.get(key) != null) {

value = (String)parameterMap.get(key);

} else {

value = "";

}

parameterBuffer.append(key).append("=").append(value);

if (iterator.hasNext()) {

parameterBuffer.append("&");

}

}

}

return parameterBuffer.toString();

}

/**

* 将结果流转为字符串

* @param is

* @return

*/

public static String convertStreamToString(InputStream is) {

StringBuilder builder = new StringBuilder();

byte[] bytes = new byte[4096];

int size = 0;

try {

while ((size = is.read(bytes)) > 0) {

String str = new String(bytes, 0, size, "UTF-8");

builder.append(str);

}

} catch (IOException e) {

e.printStackTrace();

} finally {

try {

is.close();

} catch (IOException e) {

e.printStackTrace();

}

}

return builder.toString();

}

/**

* 解析返回结果

*/

public static String parseResult(String xml){

String resultCode = null;

try {

Document document = DocumentHelper.parseText(xml);

Element root = document.getRootElement();

String result = root.getStringValue();

if(result.contains(",")){

resultCode = result.split(",")[0];

}

} catch (DocumentException e) {

e.printStackTrace();

}

return resultCode;

}

}

因为短信接口返回的是一个xml的字符串，具体内容如下：

在这里使用Dom4j 进行解析，解析方法parseResult，而translateParams方法是将Map中的参数进行拼接，一个工具方法。
