Envoyer une post-requête avec params en utilisant Retrofit
J'essaie en vain de consommer une API sur Android en utilisant la bibliothèque Retrofit, mais tout en utilisant POSTMAN, je peux voir les résultats attendus.
POSTMAN SETTING
L'URI de l'API (base + contrôleur)
Méthode HTTP définie sur POST
Cliqué sur les données de départ ou x-www-form-urlencoded
Ensuite, je passe les deux paramètres sur les champs clé/valeur.
RÉGLAGE Android RETROFIT
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Query("code") String code,
@Query("monthact") String monthact,
Callback<LandingPageReport> cb);
@FormUrlEncoded
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Field("code") String code,
@Field("monthact") String monthact,
Callback<LandingPageReport> cb);
Aucune de ces options ne fonctionne. Mais je reçois {} comme résultat.
MISE À JOUR
Les mêmes paramètres utilisant la classe standard HttpClient (et HttpPost) fonctionnent bien.
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url);
List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();
urlParameters.add(new BasicNameValuePair("code", "testcode"));
urlParameters.add(new BasicNameValuePair("monthact", "feb-2015"));
post.setEntity(new UrlEncodedFormEntity(urlParameters));
HttpResponse response = client.execute(post);
Pourquoi je ne peux pas faire cette demande et obtenir la réponse correcte dans Retrofit?
PDATE 2
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Query("code") String code,
@Query("monthact") String monthact,
Callback<List<LandingPageReport>> cb);
@FormUrlEncoded
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Field("code") String code,
@Field("monthact") String monthact,
Callback<List<LandingPageReport>>> cb);
Après avoir joué, je pense avoir trouvé la source du problème. J'ai mis à jour mon code de modification pour recevoir List<LandingPageReport>. Mais maintenant cette erreur se produit
retrofit.RetrofitError: com.google.gson.JsonSyntaxException: Java.lang.IllegalStateException: BEGIN_ARRAY attendu mais BEGIN_OBJECT à la ligne 1 colonne 2 chemin $
La raison en est que je consomme 2 api (webapi et wcf). Toutes mes autres réponses json sont des tableaux d'objets. [{}, {}] mais dans cet appel j'ai reçu ceci
{
"GetDetailWithMonthWithCodeResult": [
{
"code": "test",
"field1": "test",
}
]
}
Mais je n'arrive toujours pas à analyser la réponse.
J'ai trouvé la solution. La question était un problème dans la structure de mes classes. Donc je les ai mis à jour comme les exemples suivants.
public class LandingPageReport {
private ArrayList<LandingPageReportItem> GetDetailWithMonthWithCodeResult;
// + Getter Setter methods
}
public class LandingPageReportItem {
private String code;
private String field1;
// + Getter Setter methods
}
Et puis j'utilise cette configuration de rattrapage
@POST("/GetDetailWithMonthWithCode")
void getLandingPageReport(@Field("code") String code,
@Field("monthact") String monthact,
Callback<LandingPageReport> cb);

Ceci est une solution simple où nous n'avons pas besoin d'utiliser JSON
public interface RegisterAPI {
@FormUrlEncoded
@POST("/RetrofitExample/insert.php")
public void insertUser(
@Field("name") String name,
@Field("username") String username,
@Field("password") String password,
@Field("email") String email,
Callback<Response> callback);
}
méthode d'envoi de données
private void insertUser(){
//Here we will handle the http request to insert user to mysql db
//Creating a RestAdapter
RestAdapter adapter = new RestAdapter.Builder()
.setEndpoint(ROOT_URL) //Setting the Root URL
.build(); //Finally building the adapter
//Creating object for our interface
RegisterAPI api = adapter.create(RegisterAPI.class);
//Defining the method insertuser of our interface
api.insertUser(
//Passing the values by getting it from editTexts
editTextName.getText().toString(),
editTextUsername.getText().toString(),
editTextPassword.getText().toString(),
editTextEmail.getText().toString(),
//Creating an anonymous callback
new Callback<Response>() {
@Override
public void success(Response result, Response response) {
//On success we will read the server's output using bufferedreader
//Creating a bufferedreader object
BufferedReader reader = null;
//An string to store output from the server
String output = "";
try {
//Initializing buffered reader
reader = new BufferedReader(new InputStreamReader(result.getBody().in()));
//Reading the output in the string
output = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
//Displaying the output as a toast
Toast.makeText(MainActivity.this, output, Toast.LENGTH_LONG).show();
}
@Override
public void failure(RetrofitError error) {
//If any error occured displaying the error as toast
Toast.makeText(MainActivity.this, error.toString(),Toast.LENGTH_LONG).show();
}
}
);
}
Maintenant, nous pouvons obtenir la demande de publication en utilisant php ou n'importe quel autre script côté serveur.
Vous devriez créer une interface pour ça, comme ça marche bien
public interface Service {
@FormUrlEncoded
@POST("v1/EmergencyRequirement.php/?op=addPatient")
Call<Result> addPerson(@Field("BloodGroup") String bloodgroup,
@Field("Address") String Address,
@Field("City") String city, @Field("ContactNumber") String contactnumber,
@Field("PatientName") String name,
@Field("Time") String Time, @Field("DonatedBy") String donar);
}

et vous pouvez visiter https://github.com/rajkumu12/GetandPostUsingRatrofit
La bonne façon à mon avis est de l'envoyer dans le POST Body _ cela signifie que vous devrez créer un nouveau POJO, mais certains aimeront peut-être le plus cette implémentation.
public interface APIInterface {
@POST("/GetDetailWithMonthWithCode")
List<LandingPageReport> getLandingPageReport(@Body Report report);
}
Faites ensuite votre POJO avec un constructeur, des getters et des setters.
public static class Report {
private String code;
private String monthact;
public Report(String code, String monthact) {
this.code = code;
this.monthact = monthact;
}
// Getters and Setters...
}
Et appelez ça comme ça.
Call<List<Report>> request = apiInterface
.createRetrofitAPIInterface()
.getLandingPageReport(new Report(code, monthact));
