HttpClient x-www-form-urlencoded

1. Submit a POST request using Apache HttpClient

HTTP tool method (need to specify encoding, otherwise error, UTF-8 used here)

 Public StaticString postwithparamsforstring (string URL, list<namevaluepair>params) {HttpClient Client=Httpclients.createdefault (); HttpPost HttpPost=Newhttppost (URL); String s= ""; Try{httppost.setentity (NewUrlencodedformentity (params, "UTF-8")); Httppost.setheader ("Content-type", "application/x-www-form-urlencoded"); HttpResponse Response=Client.execute (HttpPost); intStatusCode =response.getstatusline (). Getstatuscode (); if(statuscode==200) {httpentity entity=response.getentity (); S=entityutils.tostring (entity); }        } Catch(IOException e) {e.printstacktrace (); }        returns; }

Test method

 Public Static voidMain (string[] args) {String Smskey= "AAAAAAA"; String content= "Your order number is: 4322311"; String Phone= "111111"; String Smssecret= "BBBB"; String Smsurl= "Http://iccc/v1/message/content/send"; List<NameValuePair> params =NewArraylist<namevaluepair>(); String timestamp=string.valueof (System.currenttimemillis ()); String signcontent= "appkey=" + Smskey + "&content=" + content + "&mobile=" + Phone + "&timestamp=" + timestamp + "&appsecret=" +Smssecret; String Sign=Digestutils.md5hex (signcontent). toUpperCase (); Namevaluepair pair=NewBasicnamevaluepair ("Appkey", Smskey); Namevaluepair Pair2=NewBasicnamevaluepair ("Content", content); Namevaluepair Pair3=NewBasicnamevaluepair ("mobile", phone); Namevaluepair PAIR4=NewBasicnamevaluepair ("timestamp", timestamp); Namevaluepair PAIR5=NewBasicnamevaluepair ("Sign", sign);        Params.add (pair);        Params.add (PAIR2);        Params.add (PAIR3);        Params.add (PAIR4);        Params.add (PAIR5); String postforstring= Httputil.postwithparamsforstring (Smsurl, params);
}
