HttpClient + TestNG Interface Automatic Test chapter II

The request address is generated by parameter and parameter signatures, for example:

Http://ip/server?method=getPlans&planDate=2014-08-25&cinemaId=101&uid=remote&enc= d0fe8420c641dd87d4165c09fe1d0c70&time_stamp=1408960607250

1. Build URLs

1) First build parameters to

 Public Static Hashmap<string, string> Cinemas () {        HashMapnew hashmap<string, string>();        Params.put ("method", "Getcinemas");        Params.put ("UID", starttest.username);         return params;    }

2) generate parameter pairs that contain parameter signatures

 Public StaticList<namevaluepair> getformparams (hashmap<string, string>params) {List<NameValuePair> Formparams =NewArraylist<namevaluepair>();  for(Entry<string, string>E:params.entryset ()) {Formparams.add (NewBasicnamevaluepair (E.getkey (), E.getvalue ())); } formparams.add (NewBasicnamevaluepair ("Time_stamp", string.valueof (NewDate (). GetTime ())); Formparams.add (NewBasicnamevaluepair ("Enc", Getenc.getenc (Formparams, Starttest.password)); returnFormparams; }

3) Generate Request URL

     Public Static URI getUrl (list<namevaluepair> formparams, String HOST, String PATH) {        null;         Try {            new UriBuilder (). SetScheme ("http"). Sethost (HOST).                    SetPath (PATH). Setparameters (Formparams). build ();         Catch (URISyntaxException e) {            e.printstacktrace ();        }         return uri;    }

2. Send a request after building the URL

 Public StaticHttpentity getentity (hashmap<string, string>params, string HOST, String PATH) {httpentity entity=NULL; Closeablehttpclient httpclient=Httpclients.createdefault (); Try {            //Create a HttpGet request. HttpGet HttpGet =NewHttpGet (GetUrl (Getformparams (params), HOST, PATH)); //perform a GET requestCloseablehttpresponse response =Httpclient.execute (HttpGet); Try {                //put the response into the entity carrierentity =response.getentity (); if(Entity! =NULL) {Entity=Newbufferedhttpentity (entity); if(StartTest.log) {Resultslog.writefile (entityutils.tostring (Entity,"UTF-8"), Starttest.path); }                    }            } finally{response.close (); }        } Catch(clientprotocolexception e) {e.printstacktrace (); } Catch(ParseException e) {e.printstacktrace (); } Catch(IOException e) {e.printstacktrace (); } finally {            //Disconnect Connection            Try{httpclient.close (); } Catch(IOException e) {e.printstacktrace (); }        }        returnentity; }

3. Parse the target JSON data and return the target array

 Public Staticstring[] Targetarray (String Sourcejson, String targetfield) {string targetarray[]=NULL; Jsonobject JS=Jsonobject.fromobject (Sourcejson); if(Sourcejson.contains ("Data") {Jsonarray Datajsonarray= Js.getjsonarray ("Data"); Targetarray=Newstring[datajsonarray.size ()];  for(inti=0; I<datajsonarray.size (); i++) {Targetarray[i]=(Jsonobject.fromobject (datajsonarray.getstring (i))). GetString (Targetfield); }    }  Else{targetarray[0] = js.getstring ("Errcode") + "----" + js.getstring ("ErrMsg"); }    returnTargetarray;}

4. Execute the request URL and parse back the JSON data to get the target value to form the array

     Public StaticString[] Targetvaluearray (hashmap<string, string>params, String Targetfield) {String targetarray[]=NULL; Httpentity Entity=getpost.getentity (params, starttest.round_host, Starttest.round_path); Try{Targetarray=Jsonparsing.targetarray (entityutils.tostring (Entity,"UTF-8"), Targetfield); } Catch(IllegalStateException e) {e.printstacktrace (); } Catch(IOException e) {e.printstacktrace (); }        returnTargetarray; }

Now send GET request from build url-->--parse JSON data get target value completed
