Question

我正在将json对象转换为java对象，但我一直在收到错误 com.google.gson.JsonSyntaxException：com.google.gson.stream.MalformedJsonException：第1行第20行的未终止对象路径$ [0] .urlToImage

这是我的代码

public void onResponse(JSONObject response) {
            JSONArray recArticles = new JSONArray();
            try {
                recArticles = response.getJSONArray("articles");
                for (int i=0;i<recArticles.length();i++) {
                    JSONObject jsonObject = recArticles.getJSONObject(i);;

                    String author = jsonObject.getString("author");
                    String title = jsonObject.getString("title");
                    String description = jsonObject.getString("description");
                    String url = jsonObject.getString("url");
                    String urlToImage = jsonObject.getString("urlToImage");
                    HashMap<String, String> singleArticle = new HashMap<String, String>();
                    singleArticle.put("author", author);
                    singleArticle.put("title", title);
                    singleArticle.put("description", description);
                    singleArticle.put("url", url);
                    singleArticle.put("urlToImage", urlToImage);
                    mArticleList.add(String.valueOf(singleArticle));
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
            Gson gson = new Gson();
            Type articleListType = new TypeToken<Collection<RecArticle>>() {}.getType();
            Log.d(TAG, "onResponse: " + mArticleList);
            Log.d(TAG, "onResponse: " + String.valueOf(mArticleList));
            mArticles = gson.fromJson(String.valueOf(mArticleList), articleListType);
            mArticleAdapter = new RecommenderAdapter(getContext(), mArticles);
            mRecyclerView.setAdapter(mArticleAdapter);

            mAviLib.hide();
            mRefreshLayout.setRefreshing(false);
        }

您的Json回复似乎是正确的。

但是为什么你要用gson和其他一半手动解析你的一半？完全没有逻辑。

使用它就像那样：

<强> Article.java

package com.example;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class Article {

@SerializedName("author")
@Expose
private String author;
@SerializedName("title")
@Expose
private String title;
@SerializedName("description")
@Expose
private String description;
@SerializedName("url")
@Expose
private String url;
@SerializedName("urlToImage")
@Expose
private String urlToImage;
@SerializedName("publishedAt")
@Expose
private String publishedAt;

public String getAuthor() {
return author;
}

public void setAuthor(String author) {
this.author = author;
}

public String getTitle() {
return title;
}

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

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public String getUrl() {
return url;
}

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

public String getUrlToImage() {
return urlToImage;
}

public void setUrlToImage(String urlToImage) {
this.urlToImage = urlToImage;
}

public String getPublishedAt() {
return publishedAt;
}

public void setPublishedAt(String publishedAt) {
this.publishedAt = publishedAt;
}

}

ResponseModel.java

package com.example;

import java.util.List;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class ResponseModel {

@SerializedName("status")
@Expose
private String status;
@SerializedName("source")
@Expose
private String source;
@SerializedName("sortBy")
@Expose
private String sortBy;
@SerializedName("articles")
@Expose
private List<Article> articles = null;

public String getStatus() {
return status;
}

public void setStatus(String status) {
this.status = status;
}

public String getSource() {
return source;
}

public void setSource(String source) {
this.source = source;
}

public String getSortBy() {
return sortBy;
}

public void setSortBy(String sortBy) {
this.sortBy = sortBy;
}

public List<Article> getArticles() {
return articles;
}

public void setArticles(List<Article> articles) {
this.articles = articles;
}

}

并解析如下：

public void onResponse(JSONObject response) {

            Gson gson = new Gson();
            ResponseModel responseModel = gson.fromJson(response.toString(), ResponseModel.class);
            List<Article> articles = responseModel.getArticles();
            mArticleAdapter = new RecommenderAdapter(getContext(), articles);
            mRecyclerView.setAdapter(mArticleAdapter);

            mAviLib.hide();
            mRefreshLayout.setRefreshing(false);
        }
