Answer 1

我遇到过同样的问题，我必须将JSONArray传递给注册请求。这是我得到的解决方案。

首先创建一个名为ApiClient的类，如下所示：

    public class ApiClient {

    private static Retrofit retrofit = null;
    private static String BASE_URl = Urls.BASE_URL;


    public static Retrofit getClient() {
        OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
        httpClient.connectTimeout(20 * 1000, TimeUnit.MILLISECONDS);
        httpClient.readTimeout(20 * 1000, TimeUnit.MILLISECONDS);
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        httpClient.addInterceptor(loggingInterceptor);

        if (retrofit == null) {
            retrofit = new Retrofit.Builder()
                    .client(httpClient.build())
                    .baseUrl(BASE_URl)
                    .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
        }

        return retrofit;

    }
}

创建一个接口来调用apiclient类，如下所示：

public interface ApiInterface {

    @POST(Urls.registerUserUrl)
    Observable<LoginResponseEntity> getRegistrationResponse(@Body JsonObject request); // make sure JsonObject should be from com.google.gson
}

现在调用解析器：

ApiInterface apiService =
        ApiClient.getClient().create(ApiInterface.class);
Observable<LoginResponseEntity> call = apiService.getRegistrationResponse(getRegistrationRequestParameters());
call.subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new DisposableObserver<LoginResponseEntity>() {
            @Override
            public void onNext(LoginResponseEntity loginResponseEntity) {
                // handle your response here
            }

            @Override
            public void onError(Throwable e) {

            }

            @Override
            public void onComplete() {
            }
        });



private JsonObject getRegistrationRequestParameters() {
JSONObject commonParameters = UDF.commonParametersForJson(activity);
try {
    JSONObject parentInformation = new JSONObject();
    parentInformation.put("firstname", "" + firstName);
    parentInformation.put("lastname", "" + lastName);
    parentInformation.put("contact", "" + phoneNumber);
    parentInformation.put("password", "" + password);
    commonParameters.put("personalinfo", parentInformation);
    JSONObject childObject = null;
    JSONArray childInformation = new JSONArray();
    for (int i = 0; i < alChildRequestEntity.size(); i++) {
        childObject = new JSONObject();
        childObject.put("childname", alChildRequestEntity.get(i).getName());
        childObject.put("pickupstopcode", alChildRequestEntity.get(i).getPickup_stop());
        childObject.put("dropoffstopcode", alChildRequestEntity.get(i).getDrop_stop());
        childInformation.put(childObject);
    }
    commonParameters.put("childinfo", childInformation);
} catch (JSONException e) {
    e.printStackTrace();
}
JsonParser jsonParser = new JsonParser();
JsonObject gsonObject = (JsonObject) jsonParser.parse(commonParameters.toString());   // make sure JsonObject should be from com.google.gson
return gsonObject;

}

Answer 2

使用以下代码将Arraylist转换为字符串并且其工作正常：

Gson gson = new Gson（）; String customDishListString = gson.toJson（customDishArrayList）;

在请求正文中发送数组不起作用：使用改进2.1.0
