URL url = null

string CorpID = " * * * * * * * * * "； //Account name

string Pwd = " * * * * * * * * * "； //password

string send _ content = URL encoder . encode(content . replace all(" & lt； br/>、“)、“GBK”)； //Send content

URL = new URL("/SDK 2/batch send 2 . aspx？ CorpID = "+CorpID+" & amp； Pwd = "+Pwd+" & amp； Mobile phone = "+mobile phone+"&; content = "+send _ content+" & amp； Cell = & ampsend time = "+send _ time)；

BufferedReader in = nullint inputLine = 0； Try {

System.out.println ("The mobile phone number that started sending short messages is"+mobile ");

in = new buffered reader(new InputStreamReader(URL . openstream()))；

InputLine = new integer (in.readLine ()). int value()；

Catch (exception e) {

System.out.println ("Network abnormal, sending SMS failed!" );

input line =-2；

}

System.out.println ("Return value after sending SMS:"+InputLine); Return to inputLine
