Bonjour à tous !

Pour un projet, j'ai besoin de récupérer les articles du NY Times grâce à leur API.

J'ai utilisé JSONschema pour créer mes class qui de/serialize les données du JSON.

Voici le JSON en l'état brut :

{
  "status": "OK",
  "copyright": "Copyright (c) 2018 The New York Times Company. All Rights Reserved.",
  "section": "home",
  "last_updated": "2018-01-18T04:29:08-05:00",
  "num_results": 46,
  "results": [
    {
      "section": "Briefing",
      "subsection": "",
      "title": "Angela Merkel, Brexit, Winter Olympics: Your Thursday Briefing",
      "abstract": "Here’s what you need to know to start your day.",
      "url": "https://www.nytimes.com/2018/01/17/briefing/angela-merkel-brexit-winter-olympics.html",
      "byline": "By PATRICK BOEHLER",
      "item_type": "Article",
      "updated_date": "2018-01-18T00:13:23-05:00",
      "created_date": "2018-01-17T23:59:53-05:00",
      "published_date": "2018-01-17T23:59:53-05:00",
      "material_type_facet": "",
      "kicker": "",
      "des_facet": [],
      "org_facet": [],
      "per_facet": [],
      "geo_facet": [],
      "multimedia": [
        {
          "url": "https://static01.nyt.com/images/2018/01/18/briefing/18amBriefiing-Europe-core-container-gif-trypt/18amBriefiing-Europe-ss-slide-IIW6-thumbStandard.jpg",
          "format": "Standard Thumbnail",
          "height": 75,
          "width": 75,
          "type": "image",
          "subtype": "photo",
          "caption": "",
          "copyright": "Doug Mills/The New York Times'"
        },
.......

 Les différentes class générées par JSONSchema :

public class TopStoriesMain {

    @SerializedName("status")
    @Expose
    private String status;
    @SerializedName("num_results")
    @Expose
    private Integer numResults;
    @SerializedName("results")
    @Expose
    private List<TopStoriesResult> results = null;

        this.status = status;
    }

    public Integer getNumResults() {
        return numResults;
    }

    public void setNumResults(Integer numResults) {
        this.numResults = numResults;
    }

    public List<TopStoriesResult> getResults() {
        return results;
    }

    public void setResults(List<TopStoriesResult> topStoriesResults) {
        this.results = topStoriesResults;
    }

}

public class TopStoriesResult {

    public String getSection() {
        return section;
    }

    public void setSection(String section) {
        this.section = section;
    }

    public String getSubsection() {
        return subsection;
    }

    public void setSubsection(String subsection) {
        this.subsection = subsection;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAbstract() {
        return _abstract;
    }

    public void setAbstract(String _abstract) {
        this._abstract = _abstract;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getByline() {
        return byline;
    }

    public void setByline(String byline) {
        this.byline = byline;
    }

    public String getPublishedDate() {
        return publishedDate;
    }

    public void setPublishedDate(String publishedDate) {
        this.publishedDate = publishedDate;
    }

    public List<Object> getDesFacet() {
        return desFacet;
    }

    public void setDesFacet(List<Object> desFacet) {
        this.desFacet = desFacet;
    }

    public List<Object> getOrgFacet() {
        return orgFacet;
    }

    public void setOrgFacet(List<Object> orgFacet) {
        this.orgFacet = orgFacet;
    }

    public List<Object> getPerFacet() {
        return perFacet;
    }

    public void setPerFacet(List<Object> perFacet) {
        this.perFacet = perFacet;
    }

    public List<Object> getGeoFacet() {
        return geoFacet;
    }

    public void setGeoFacet(List<Object> geoFacet) {
        this.geoFacet = geoFacet;
    }

    public List<TopStoriesMultimedia> getMultimedia() {
        return multimedia;
    }

    public void setMultimedia(List<TopStoriesMultimedia> topStoriesMultimedia) {
        this.multimedia = topStoriesMultimedia;
    }

}

public class TopStoriesMultimedia {

    @SerializedName("url")
    @Expose
    private String url;
    @SerializedName("caption")
    @Expose
    private String caption;

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getCaption() {
        return caption;
    }

    public void setCaption(String caption) {
        this.caption = caption;
    }

}

A noter que j'ai supprimé (dans les fichiers générés par JSONSchema) les informations dont je n'avais pas besoin.

Et voici l'erreur :

E/TAG: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

La traduction n'est pas bien compliquée mais au niveau du code j'avoue ne pas trouver l'erreur ...

En vous remerciant d'avance pour vos réponse !

Bonjour, comment avez-vous résolu ce problème ?

Je rencontre le même en ce moment
