Comment envoyer des données json à la POSTE de service restful

Je veux appeler un repos webservice avec la méthode POST.Ci-dessous est l'url du service et de ses paramètres de qui j'ai besoin de passer

 Rest Service: https://url/SSOServer/SSO.svc/RestService/Login

Json Object {"ProductCode":"AB","DeviceType":"android Simulator","UserName":"","ModuleCode":"AB_MOBILE","DeviceId":"device-id","Version":"1.0.0.19","CustomerCode":"w","Password":""}

Voici mon post de demande de code:

public void sendHttpPost() throws ClientProtocolException, IOException{
        HttpPost httpPostRequest = new HttpPost(url + buildParams());

        //add headers
        Iterator it = headers.entrySet().iterator();
        Iterator itP = params.entrySet().iterator();
        while (it.hasNext()) {
            Entry header = (Entry) it.next();
            httpPostRequest.addHeader((String)header.getKey(), (String)header.getValue());
        }

        HttpClient client = new DefaultHttpClient();
        HttpResponse resp;

        resp = client.execute(httpPostRequest);

        this.respCode = resp.getStatusLine().getStatusCode();
        Log.i(TAG, "response code: " + getResponseCode());
        this.responsePhrase = resp.getStatusLine().getReasonPhrase();
        Log.i(TAG, "error msg: " + getErrorMsg());
        HttpEntity entity = resp.getEntity();

        if (entity != null){
            InputStream is = entity.getContent();
            //Header contentEncoding = resp.getFirstHeader("Content-encoding");
            //Log.i(TAG, "endoding" + contentEncoding.getValue());
            response = convertStreamToString(is);
            //response = response.substring(1,response.length()-1);
            //response = "{" + response + "}";
            Log.i(TAG, "response: " + response);
            is.close();
        }
    }

Ma question est de savoir comment ajouter des données json à cette demande??

    Utiliser en dessous de la classe

    public class RestClient
{
private ArrayList<NameValuePair> params;
private ArrayList<NameValuePair> headers;
private String url;
private int responseCode;
private String message;
private String response;
public String getResponse()
{
return response;
}
public String getErrorMessage()
{
return message;
}
public int getResponseCode()
{
return responseCode;
}
public RestClient(String url) {
this.url = url;
params = new ArrayList<NameValuePair>();
headers = new ArrayList<NameValuePair>();
}
public void AddParam(String name, String value)
{
params.add(new BasicNameValuePair(name, value));
}
public void AddHeader(String name, String value)
{
headers.add(new BasicNameValuePair(name, value));
}
public void Execute(RequestMethod method) throws Exception
{
switch (method)
{
case GET:
{
//add parameters
String combinedParams = "";
if (!params.isEmpty())
{
combinedParams += "";
for (NameValuePair p : params)
{
String paramString = p.getName() + "" + URLEncoder.encode(p.getValue(),"UTF-8");
if (combinedParams.length() > 1)
{
combinedParams += "&" + paramString;
}
else
{
combinedParams += paramString;
}
}
}
HttpGet request = new HttpGet(url + combinedParams);
//add headers
for (NameValuePair h : headers)
{
request.addHeader(h.getName(), h.getValue());
}
executeRequest(request, url);
break;
}
case POST:
{
HttpPost request = new HttpPost(url);
//add headers
for (NameValuePair h : headers)
{
request.addHeader(h.getName(), h.getValue());
}
if (!params.isEmpty())
{
request.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
}
executeRequest(request, url);
break;
}
}
}
private void executeRequest(HttpUriRequest request, String url) throws Exception
{
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters,15000);
HttpConnectionParams.setSoTimeout(httpParameters, 15000);
HttpClient client = new DefaultHttpClient(httpParameters);
HttpResponse httpResponse;
httpResponse = client.execute(request);
responseCode = httpResponse.getStatusLine().getStatusCode();
message = httpResponse.getStatusLine().getReasonPhrase();
HttpEntity entity = httpResponse.getEntity();
if (entity != null)
{
InputStream instream = entity.getContent();
response = convertStreamToString(instream);
//Closing the input stream will trigger connection release
instream.close();
}
}
private static String convertStreamToString(InputStream is)
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try
{
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
}
catch (IOException e)
{
e.printStackTrace();
}
finally
{
try
{
is.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}
return sb.toString();
}
public InputStream getInputStream(){
HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters,15000);
HttpConnectionParams.setSoTimeout(httpParameters, 15000);
HttpClient client = new DefaultHttpClient(httpParameters);
HttpResponse httpResponse;
try
{
HttpPost request = new HttpPost(url);
httpResponse = client.execute(request);
responseCode = httpResponse.getStatusLine().getStatusCode();
message = httpResponse.getStatusLine().getReasonPhrase();
HttpEntity entity = httpResponse.getEntity();
if (entity != null)
{
InputStream instream = entity.getContent();
return instream;
/*   response = convertStreamToString(instream);
//Closing the input stream will trigger connection release
instream.close();*/
}
}
catch (ClientProtocolException e)
{
client.getConnectionManager().shutdown();
e.printStackTrace();
}
catch (IOException e)
{
client.getConnectionManager().shutdown();
e.printStackTrace();
}
return null;
}
public enum RequestMethod
{
GET,
POST
}
}

    Voici le code à utiliser au-dessus de la classe

    RestClient client=new RestClient(Webservices.student_details);
JSONObject obj=new JSONObject();
obj.put("StudentId",preferences.getStudentId());
client.AddParam("",obj.toString());
client.Execute(RequestMethod.GET);
String response=client.getResponse();

    Espère que cela va vous aider à

    • Vouliez-vous dire en POST ou en GET?
    • si tu veux utiliser poste client.Execute(RequestMethod.La POSTE);
    • Qu'est-ce que les Services web.student_details? Est-ce qu'une URL? Et aussi ne vous oublie pas "importer ..." déclarations? Spécialement pour NameValuePair, BasicNameValuePair, HttpGet,...etc.
    • vraiment de réponse complète!

    Q: comment ajouter des données json à cette demande?

    A: Définir votre type de contenu, la longueur et l'écriture de la charge utile.

    Voici un exemple:

     JSONObject titulaire = new JSONObject(); 
... 
JSONObject de données = new JSONObject(); 
... 
//Quelques exemples de paires nom=valeur 
while(iter.hasNext()) { 
Carte.Entrée paires = (Map.D'entrée)iter.next(); 
String clé = (String)paires.getKey(); 
Carte m = (Map)paires.getValue(); 
JSONObject de données = new JSONObject(); 
Itérateur iter2 = m.entrySet().iterator(); 
while(iter2.hasNext()) { 
Carte.Entrée pairs2 = (Map.D'entrée)iter2.next(); 
les données.mettre((String)pairs2.getKey(), (String)pairs2.getValue()); 
} 
le titulaire.put(clé, les données); 
} 
... 
StringEntity se = new StringEntity(titulaire.toString()); 
... 
httpost.setHeader("Accepter", "application/json"); 
httpost.setHeader("Content-type", "application/json"); 
...
    • est-ce une blague???
