改造模型组织

Question

我在Retrofit里遇到了一个可以扔的东西

retrofit.RetrofitError: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 246 path $.suggested.taxonomies[1].payload.scope.

我有什么？

我有一个Payload.class，用于从api获取所有数据，有很多嵌套的东西，但是我尝试实现的是LinkedTreeMap<Object, ScopeModel> scope。

Payload.class：

public class Payload {

    @SerializedName("product_id")
    @Expose
    private String productId;
    @SerializedName("primary_image")
    @Expose
    private String primaryImage;
    @SerializedName("rating")
    @Expose
    private String rating;
    @SerializedName("review_count")
    @Expose
    private String reviewCount;
    @SerializedName("url")
    @Expose
    private String url;
    @SerializedName("scope")
    @Expose //TODO fix this
    private LinkedTreeMap<Object, ScopeModel> scope = new LinkedTreeMap<>();
    @SerializedName("direct_link")
    @Expose
    private String directLink;
    @SerializedName("keyword")
    @Expose
    private String keyword;

    public String getProductId() {
        return productId;
    }

    public void setProductId(String productId) {
        this.productId = productId;
    }

    public String getPrimaryImage() {
        return primaryImage;
    }

    public void setPrimaryImage(String primaryImage) {
        this.primaryImage = primaryImage;
    }

    public String getRating() {
        return rating;
    }

    public void setRating(String rating) {
        this.rating = rating;
    }

    public String getReviewCount() {
        return reviewCount;
    }

    public void setReviewCount(String reviewCount) {
        this.reviewCount = reviewCount;
    }

    public String getUrl() {
        return url;
    }

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

    public LinkedTreeMap<Object, ScopeModel> getScope() {
        return scope;
    }

    public void setScope(LinkedTreeMap<Object, ScopeModel> scope) {
        this.scope = scope;
    }

    public String getDirectLink() {
        return directLink;
    }

    public void setDirectLink(String directLink) {
        this.directLink = directLink;
    }

    public String getKeyword() {
        return keyword;
    }

    public void setKeyword(String keyword) {
        this.keyword = keyword;
    }
}

以及我在LinkedTreeeMap中使用的LinkedTreeeMap

public class ScopeModel {

    @SerializedName("id")
    @Expose
    private String id;

    @SerializedName("name")
    @Expose
    private String name;

    @SerializedName("type")
    @Expose
    private String type;

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
}

我为什么要使用LinkedTreeMap？我不明白为什么(我在android中是新手) :D.我的逻辑是:当我将LinkedTreeMap<Object,ScopeModel> scope更改为Payload中的Object scope;时，我在调试器中找到了这样的东西：

​

正如我所理解的那样，API用我需要的数据返回LinkedTreeMap，因此我试图制作ScopeModel等等。我能用我的代码做什么？

不管怎样，谢谢你，为我的英语道歉！

Answer 1

尝试开关

@SerializedName("scope")
@Expose //TODO fix this
private LinkedTreeMap<Object, ScopeModel> scope = new LinkedTreeMap<>();

至

@SerializedName("scope")
@Expose //TODO fix this
private ScopeModel scope;
