Android 改型无法解析JSON:BEGIN\u数组，但它是带有hackernews api的BEGIN\u对象

这是JSON fron

这是我的密码

使用www.jsonschema2pojo.org创建的文章POJO

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
    "title",
    "url",
    "id",
    "commentCount",
    "points",
    "postedAgo",
    "postedBy"
})
public class Article {

@JsonProperty("title")
private String title;
@JsonProperty("url")
private String url;
@JsonProperty("id")
private Integer id;
@JsonProperty("commentCount")
private Integer commentCount;
@JsonProperty("points")
private Integer points;
@JsonProperty("postedAgo")
private String postedAgo;
@JsonProperty("postedBy")
private String postedBy;
private String image;
@JsonIgnore
private Map<String, Object> additionalProperties = new HashMap<String, Object>();


public String getImage() {return image;}
public void setImage(String image){this.image = image;}
@JsonProperty("title")
public String getTitle() {
    return title;
}

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

public Article withTitle(String title) {
    this.title = title;
    return this;
}

@JsonProperty("url")
public String getUrl() {
    return url;
}

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

public Article withUrl(String url) {
    this.url = url;
    return this;
}

@JsonProperty("id")
public Integer getId() {
    return id;
}

@JsonProperty("id")
public void setId(Integer id) {
    this.id = id;
}

public Article withId(Integer id) {
    this.id = id;
    return this;
}

@JsonProperty("commentCount")
public Integer getCommentCount() {
    return commentCount;
}

@JsonProperty("commentCount")
public void setCommentCount(Integer commentCount) {
    this.commentCount = commentCount;
}

public Article withCommentCount(Integer commentCount) {
    this.commentCount = commentCount;
    return this;
}

@JsonProperty("points")
public Integer getPoints() {
    return points;
}

@JsonProperty("points")
public void setPoints(Integer points) {
    this.points = points;
}

public Article withPoints(Integer points) {
    this.points = points;
    return this;
}

@JsonProperty("postedAgo")
public String getPostedAgo() {
    return postedAgo;
}

@JsonProperty("postedAgo")
public void setPostedAgo(String postedAgo) {
    this.postedAgo = postedAgo;
}

public Article withPostedAgo(String postedAgo) {
    this.postedAgo = postedAgo;
    return this;
}

@JsonProperty("postedBy")
public String getPostedBy() {
    return postedBy;
}

@JsonProperty("postedBy")
public void setPostedBy(String postedBy) {
    this.postedBy = postedBy;
}

public Article withPostedBy(String postedBy) {
    this.postedBy = postedBy;
    return this;
}

@Override
public String toString() {
    return ToStringBuilder.reflectionToString(this);
}

@Override
public int hashCode() {
    return HashCodeBuilder.reflectionHashCode(this);
}

@Override
public boolean equals(Object other) {
    return EqualsBuilder.reflectionEquals(this, other);
}

@JsonAnyGetter
public Map<String, Object> getAdditionalProperties() {
    return this.additionalProperties;
}

@JsonAnySetter
public void setAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
}

public Article withAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
    return this;
}

}

我用这个得到了json

ApiClient.getUnlockApiClient().getArticles(new Callback<List<Article>>(){
        @Override
        public void success(List<Article> articles, Response response) {
            for (Article article : articles) {
                 Log.i(TAG,article.toJSON());
            }

        }

知道如何解决这个问题吗？

您试图解析一个项目数组，但响应只是一个对象。因此，为了使其正常工作，您可以创建一个新类

Response

，该类将有两个字段

nextId

和

List

，为它们添加适当的注释，希望这能起到作用

之后，您可以从

响应

对象中检索

文章

的列表

}

private static UnlockApiInterface unlockService;

public static UnlockApiInterface getUnlockApiClient(){
    if(unlockService==null){
        RestAdapter restAdapter = new RestAdapter.Builder()
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .setEndpoint("http://api.ihackernews.com")
                .build();
        unlockService = restAdapter.create(UnlockApiInterface.class);
    }
    return unlockService;
}

ApiClient.getUnlockApiClient().getArticles(new Callback<List<Article>>(){
        @Override
        public void success(List<Article> articles, Response response) {
            for (Article article : articles) {
                 Log.i(TAG,article.toJSON());
            }

        }
