Calculate and obtain a verification code

Send SMS to get generated verification code

String curtime=string.valueof ((New Date (). GetTime ()/1000l));

Set the header of the request
Post.addheader ("AppKey", App_key);
Post.addheader ("Nonce", nonce);
Post.addheader ("Curtime", curtime);
Post.addheader ("CheckSum", CheckSum);
Post.addheader ("Content-type", "application/x-www-form-urlencoded;charset=utf-8");

Set Request parameters

Basicnamevaluepair Basicnamevaluepair = new Basicnamevaluepair ("mobile", phone);
Namevaluepairs.add (Basicnamevaluepair);

Post.setentity (New Urlencodedformentity (Namevaluepairs, "utf-8"));

Execute request
HttpResponse Response=httpclient.execute (POST);
String responseentity= entityutils.tostring (response.getentity (), "utf-8");

To determine if the send was successful, send successful return True
String code = jsonobject.fromobject (responseentity). getString ("code");
if (Code.equals ("200")) {
Return "Success";
}
return "error";
}

Verify that the SMS Verification Code matches
