java - 如何更改API请求？

Question

我是 Android 开发新手。我有一个来自 github here 的例子。此示例展示了一种与服务器交互以获取查询建议的方法。目前请求正文有以下形式:

{
  "query": "mosc",
  "count": 10
}

我需要像这样编辑正文:

{
  "query": "mosc",
  "from_bound": { "value": "region" },
  "to_bound": { "value": "region" },
  "count": 10
}

提出请求时仅向我显示区域，而不是完整地址。

一段代码，其中请求如果形成:DaDataRestClient.java

RestAdapter restAdapter = new RestAdapter.Builder()
                .setLogLevel(BuildConfig.DEBUG ? RestAdapter.LogLevel.FULL : RestAdapter.LogLevel.NONE)
                .setEndpoint(BASE_URL)
                .setRequestInterceptor(new RequestInterceptor() {
                    @Override
                    public void intercept(RequestFacade request) {
                        request.addHeader("Content-Type", "application/json");
                        request.addHeader("Accept", "application/json");
                        request.addHeader("Authorization", "Token ".concat(BuildConfig.DADATA_API_KEY));
                    }
                })
                .setConverter(new GsonConverter(gson))
                .build();
apiService = restAdapter.create(DaDataService.class);

和 ServerUtils.java:

if (queryRealmResults.size() == 0) {
                        RealmDaDataSuggestion suggestion = null;
                        try {
                            // Synchronously get the answer from DaData
                            suggestion = DaDataRestClient.getInstance().suggestSync(new DaDataBody(queryFromUser, 10));
                            ...

和 DaDataBody 类:

public class DaDataBody {
    private String query;
    private int count;

    public DaDataBody(String query, int count) {
        this.query = query;
        this.count = count;
    }

    public String getQuery() {
        return query;
    }

    public void setQuery(String query) {
        this.query = query;
    }

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}

我已经花了很多时间，但对我来说没有任何作用:(请帮助我，我该如何编辑此请求？提前致谢!

PS:最终我想创建两个 EditText，一个用于区域，第二个用于城市。

P.P.S.:抱歉我的英语)

如下所示更新您的模型类

public class DaDataBody{

    @SerializedName("from_bound")
    private Property fromBound;

    @SerializedName("query")
    private String query;

    @SerializedName("count")
    private int count;

    @SerializedName("to_bound")
    private Property toBound;

    public void setFromBound(Property fromBound){
        this.fromBound = fromBound;
    }

    public Property getFromBound(){
        return fromBound;
    }

    public void setQuery(String query){
        this.query = query;
    }

    public String getQuery(){
        return query;
    }

    public void setCount(int count){
        this.count = count;
    }

    public int getCount(){
        return count;
    }

    public void setToBound(Property toBound){
        this.toBound = toBound;
    }

    public Property getToBound(){
        return toBound;
    }

    public class Property {

        @SerializedName("value")
        private String value;

        public void setValue(String value){
            this.value = value;
        }

        public String getValue(){
            return value;
        }


    }
}

为 API 调用创建请求正文

        DaDataBody body=new DaDataBody();
        body.setQuery("your query");
        body.setCount(10);
        //set if you have value for tobound
        body.setToBound(new Property("your value"));

        //set if you have value for frombound
        body.setFromBound(new Property("your value"));

如果没有值，请不要为 tobound 和 frombound 设置值或设置 null。因为 gson 在生成 json 时不包含空值键的键和值。
