J'utilise Retrofit pour intégrer mes services Web et je ne comprends pas comment envoyer un objet JSON au serveur via une requête POST. Je suis actuellement bloqué, voici mon code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Retrofit retrofit = new Retrofit.Builder().baseUrl(url).
addConverterFactory(GsonConverterFactory.create()).build();
PostInterface service = retrofit.create(PostInterface.class);
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("email", "[email protected]");
jsonObject.put("password", "1234");
} catch (JSONException e) {
e.printStackTrace();
}
final String result = jsonObject.toString();
}
public interface PostInterface {
@POST("User/DoctorLogin")
Call<String> getStringScalar(@Body String body);
}
{
"email":"[email protected]",
"password":"1234"
}
{
"error": false,
"message": "User Login Successfully",
"doctorid": 42,
"active": true
}
Utilisez-les en grade
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.squareup.retrofit2:converter-scalars:2.3.0'
Utilisez ces deux classes POJO ........
LoginData.class
public class LoginData {
private String email;
private String password;
public LoginData(String email, String password) {
this.email = email;
this.password = password;
}
/**
*
* @return
* The email
*/
public String getEmail() {
return email;
}
/**
*
* @param email
* The email
*/
public void setEmail(String email) {
this.email = email;
}
/**
*
* @return
* The password
*/
public String getPassword() {
return password;
}
/**
*
* @param password
* The password
*/
public void setPassword(String password) {
this.password = password;
}
}
LoginResult.class
public class LoginResult {
private Boolean error;
private String message;
private Integer doctorid;
private Boolean active;
/**
*
* @return
* The error
*/
public Boolean getError() {
return error;
}
/**
*
* @param error
* The error
*/
public void setError(Boolean error) {
this.error = error;
}
/**
*
* @return
* The message
*/
public String getMessage() {
return message;
}
/**
*
* @param message
* The message
*/
public void setMessage(String message) {
this.message = message;
}
/**
*
* @return
* The doctorid
*/
public Integer getDoctorid() {
return doctorid;
}
/**
*
* @param doctorid
* The doctorid
*/
public void setDoctorid(Integer doctorid) {
this.doctorid = doctorid;
}
/**
*
* @return
* The active
*/
public Boolean getActive() {
return active;
}
/**
*
* @param active
* The active
*/
public void setActive(Boolean active) {
this.active = active;
}
}
Utiliser l'API comme ceci
public interface RetrofitInterface {
@POST("User/DoctorLogin")
Call<LoginResult> getStringScalar(@Body LoginData body);
}
utiliser appel comme ça ....
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("Your domain URL here")
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
RetrofitInterface service = retrofit.create(RetrofitInterface .class);
Call<LoginResult> call=service.getStringScalar(new LoginData(email,password));
call.enqueue(new Callback<LoginResult>() {
@Override
public void onResponse(Call<LoginResult> call, Response<LoginResult> response) {
//response.body() have your LoginResult fields and methods (example you have to access error then try like this response.body().getError() )
}
@Override
public void onFailure(Call<LoginResult> call, Throwable t) {
//for getting error in network put here Toast, so get the error on network
}
});
MODIFIER:-
mettre ceci dans la
success()
....
if(response.body().getError()){
Toast.makeText(getBaseContext(),response.body().getMessage(),Toast.LENGTH_SHORT).show();
}else {
//response.body() have your LoginResult fields and methods (example you have to access error then try like this response.body().getError() )
String msg = response.body().getMessage();
int docId = response.body().getDoctorid();
boolean error = response.body().getError();
boolean activie = response.body().getActive()();
}
Remarque: - Toujours utiliser les classes POJO, cela supprime l'analyse des données JSON lors de la modernisation.
Cette façon fonctionne pour moi
Ajoutez ceci dans votre note
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.squareup.retrofit2:converter-scalars:2.3.0'
Interface
public interface ApiInterface {
String ENDPOINT = "http://10.157.102.22/rest/";
@Headers("Content-Type: application/json")
@POST("login")
Call<User> getUser(@Body String body);
}
Activité
public class SampleActivity extends AppCompatActivity implements Callback<User> {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ApiInterface.ENDPOINT)
.addConverterFactory(ScalarsConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
ApiInterface apiInterface = retrofit.create(ApiInterface.class);
// prepare call in Retrofit 2.0
try {
JSONObject paramObject = new JSONObject();
paramObject.put("email", "[email protected]");
paramObject.put("pass", "4384984938943");
Call<User> userCall = apiInterface.getUser(paramObject.toString());
userCall.enqueue(this);
} catch (JSONException e) {
e.printStackTrace();
}
}
@Override
public void onResponse(Call<User> call, Response<User> response) {
}
@Override
public void onFailure(Call<User> call, Throwable t) {
}
}
je pense que vous devriez maintenant créer une classe de générateur de service et après celavous devriez utiliser Call pour appeler votre service
PostInterface postInterface = ServiceGenerator.createService(PostInterface.class);
Call<responseBody> responseCall =
postInterface.getStringScalar(requestBody);
alors vous pouvez l'utiliser pour une requête synchrone et obtenir le corps de la réponse:
responseCall.execute().body();
et pour asynchrone:
responseCall.enqueue(Callback);
reportez-vous au lien fourni ci-dessous pour obtenir la procédure complète et savoir comment créer ServiceGenerator:
