Today to find a few short message platform, actually want to use a sharesdk, use it http api message function, not only low prices, and with a minimum of 100 RMB top-up but too strict review corresponding APP must also integrated their message function, but also want to upload the audit has to more than 20 days, I also just want to find a SMS platform under test, so even if it. Then in baidu casually in good 1 SMS platform www.wasun.cn, temporarily feel it is good, at least it gave the test account to accept SMS speed did not exceed 5 seconds, I looked at 1 is 3 seconds or even faster. Next, I will talk about the method to call the SMS interface, and the problems encountered in the use.
1. Request methods in httprequest mode
He gave DOMO had really good encapsulation method, is to use httpClient request, in before. NET used in this class, and. net also directly HttpWebRequest this class, I look at the code in its function should be encapsulated in the java to URLConnection inside the class, because of the time, packaging method I didn't study is from the Internet to find, but should be. The HttpWebRequest net is a meaning. The following code is pasted, including the code of httpClient of DEMO generation.
package Helper;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;

* Request parameter, request parameter should be name1=value1&name2=value2 In the form.
* @return URL The response result of the remote resource represented
*/
public static String sendGet(String url, String param) {
String result = "";
BufferedReader in = null;
try {
String urlNameString = url + "?" + param;
URL realUrl = new URL(urlNameString);
// Open and URL Connection between
URLConnection connection = realUrl.openConnection();
// Sets the generic request properties
connection.setRequestProperty("accept", "*/*");
connection.setRequestProperty("connection", "Keep-Alive");
connection.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
// Establish the actual connection
connection.connect();
// Gets all the response header fields
Map<String, List<String>> map = connection.getHeaderFields();
// Traverse all the response header fields
for (String key : map.keySet()) {
System.out.println(key + "--->" + map.get(key));
}
// define BufferedReader Input stream to read URL The response of the

connection.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
System.out.println(" send GET Request exception! " + e);
e.printStackTrace();
}
// use finally Block to close the input stream
finally {
try {
if (in != null) {
in.close();
}
} catch (Exception e2) {
e2.printStackTrace();
}
}
return result;
}

public static String sendPost(String url, String param) {
PrintWriter out = null;
BufferedReader in = null;
String result = "";
try {
URL realUrl = new URL(url);
// Open and URL Connection between
URLConnection conn = realUrl.openConnection();
// Sets the generic request properties
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
// send POST The request must be set to the following two lines
conn.setDoOutput(true);
conn.setDoInput(true);
// To obtain URLConnection The output stream corresponding to the object
out = new PrintWriter(conn.getOutputStream());

out.print(param);
// flush Buffering of the output stream

catch(IOException ex){

}
}

} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
}
2. Official DEMO httpClient request code
//import java.io.FileInputStream;
//import java.io.FileNotFoundException;
import java.io.IOException;
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;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
public class sendsms {
private static String Url = "http://121.199.?.178/webservice/sms.php?method=Submit";
public static void main(String [] args) {
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(Url);
//client.getParams().setContentCharset("GBK");
client.getParams().setContentCharset("UTF-8");
method.setRequestHeader("ContentType","application/x-www-form-urlencoded;charset=UTF-8");
String content = new String(" Your verification code is: 7528 . Please do not disclose the captcha to others. ");
NameValuePair[] data = {// Submit SMS
new NameValuePair("account", " The user name "),
new NameValuePair("password", " password "), // Passwords can be either plaintext or used 32 position MD5 encryption
//new NameValuePair("password", util.StringUtil.MD5Encode(" password ")),
new NameValuePair("mobile", " Mobile phone number "),
new NameValuePair("content", content),
};
method.setRequestBody(data);
try {
client.executeMethod(method);
String SubmitResult =method.getResponseBodyAsString();
//System.out.println(SubmitResult);
Document doc = DocumentHelper.parseText(SubmitResult);
Element root = doc.getRootElement();
String code = root.elementText("code");
String msg = root.elementText("msg");
String smsid = root.elementText("smsid");
System.out.println(code);
System.out.println(msg);
System.out.println(smsid);
if(code == "2"){
System.out.println(" SMS submission successful ");
}
} catch (HttpException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DocumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

3. Call the encapsulated httprequest code
String phoneMessageParameter=new String("account=?&password=wxhdcs@456&content= Your check code is: [variable]. Please do not disclose the checksum to others. &mobile=?&stime=2012-08-01%208:20:23&sign=?&type=pt&extno=");
String returnResult=HttpRequest.sendPost("http://121.?.16.178/webservice/sms.php?method=Submit", phoneMessageParameter);
out.println("<script> alert("+returnResult+");</script>");If you use this platform to pay attention to, is the parameter name is wrong in his official documents, send DEMO is right, and his interface was written in webserver, return not json or XML data, but rather a standard html page, and then the content of the need to write in html tag, if is test content message, this parameter must write their rules, otherwise an error, if formal purchase to set their own template content.
