错误改造获取

Question

我无法恢复数据从我的Wordpress API与改造库。错误是：HTTP FAILED：java.net.未知主机异常：无法解决主机"app.divion.fr"：没有地址与主机名关联

ApiClient：

import androidx.appcompat.app.AppCompatActivity;
import retrofit2.Call;
import kotlin.contracts.Returns;
import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class ApiClient extends AppCompatActivity {

//Adresse de l'Api

public static final String BASE_URL = "https://app.divion.fr/wp-json/api/";

//Retrofit Api Client

private static Retrofit retrofit = null;

public static Retrofit getApiClient(){
    HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
    loggingInterceptor.level(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder()
                                .addInterceptor(loggingInterceptor)
                                .build();
    if (retrofit == null){

        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}

}

API接口：

package com.example.allomairie.rest;

import java.util.Map;

import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.QueryMap;

公共接口{

// Retrofit Interface
//JSON --> GSON Library --> Java Object


@GET("homepage_api")
Call<Object> getHomepageApi(@QueryMap Map<String, String> params);

}

显示xml

    <?xml version="1.0" encoding="utf-8"?>

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Thx；）

看起来DNS服务器无法识别您指定的url。您确定https://app.divion.fr/wp-json/api/是一个实际的工作url吗？您可以在网络浏览器中复制和粘贴url，看看它是否打开一个页面进行验证。如果不是有效的url，请使用有效的。
