所谓理解，通常不过是误解的总合。——村上春树《斯普特尼克恋人》
安卓调用接口
首先引入依赖
implementation 'com.android.volley:volley:1.1.1'
implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.1.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.3.0'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.3.0'
|
然后编写主配置类
package com.example.interfacecall.net;
import android.util.Log;
import com.android.volley.BuildConfig;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class NetConfig {
public final static String BASEURL = "http://vampireachao.utools.club/";
private static Retrofit.Builder builder;
private static Retrofit retrofit;
public static Retrofit.Builder getRetrofitBuilder() {
if (builder == null) {
Gson gson = new GsonBuilder()
.setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")
.setLenient()
.create();
HttpLoggingInterceptor logging = new HttpLoggingInterceptor(message -> Log.e("OkHttp", ": " + message));
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder okHttpBuilder = new OkHttpClient.Builder();
okHttpBuilder
.readTimeout(15000, TimeUnit.MILLISECONDS)
.connectTimeout(15000, TimeUnit.MILLISECONDS)
.writeTimeout(15000, TimeUnit.MILLISECONDS)
.retryOnConnectionFailure(true);
if (BuildConfig.DEBUG) {
okHttpBuilder.addInterceptor(logging);
}
OkHttpClient httpClient = okHttpBuilder.build();
builder = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create(gson))
.client(httpClient)
.baseUrl(BASEURL);
}
return builder;
}
public static Retrofit getRetrofit() {
if (retrofit == null) {
retrofit = getRetrofitBuilder().build();
}
return retrofit;
}
public static <T> T create(Class<T> t) {
return getRetrofit().create(t);
}
}
|
以及自定义返回处理
package com.example.interfacecall.net;
import android.util.Log;
import com.google.gson.Gson;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;
public abstract class CustomCallBack<T> implements Callback<T> {
@Override
public void onResponse(Call<T> call, Response<T> response) {
Log.e("okhttp: content_result ", new Gson().toJson(response.body()));
if (response.raw().code() == 500) {
failure(new Throwable("500"));
return;
}
if (response.body() == null) {
failure(new Throwable("500"));
return;
}
response(response);
}
@Override
public void onFailure(Call<T> call, Throwable t) {
t.printStackTrace();
failure(t);
}
public abstract void response(Response<T> response);
public abstract void failure(Throwable t);
}
|
定义接口
package com.example.interfacecall.net;
import com.example.interfacecall.bean.User;
import retrofit2.Call;
import retrofit2.http.Body;
import retrofit2.http.GET;
import retrofit2.http.POST;
import retrofit2.http.Path;
import retrofit2.http.Query;
public class ProjectApi {
public interface UserProject {
@GET("user/shout")
Call<AjaxJson> shout();
@GET("user/say")
Call<AjaxJson> say(@Query("word") String word);
@GET("user/say/{word}")
Call<AjaxJson> speak(@Path("word") String word);
@POST("user/login")
Call<AjaxJson> login(@Body User user);
}
}
|
然后调用
package com.example.interfacecall;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import com.example.interfacecall.bean.User;
import com.example.interfacecall.net.AjaxJson;
import com.example.interfacecall.net.CustomCallBack;
import com.example.interfacecall.net.NetConfig;
import com.example.interfacecall.net.ProjectApi;
import com.example.interfacecall.utils.ToastUtils;
import java.util.Optional;
import retrofit2.Call;
import retrofit2.Response;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
speak();
}
private void say() {
findViewById(R.id.hello).setOnClickListener(v -> {
Call<AjaxJson> shout = NetConfig.create(ProjectApi.UserProject.class).say("阿巴阿巴阿巴");
shout.enqueue(new CustomCallBack<AjaxJson>() {
@Override
public void response(Response<AjaxJson> response) {
ToastUtils.showToast(getApplicationContext(), Optional.ofNullable(response.body()).orElse(new AjaxJson()).getData());
}
@Override
public void failure(Throwable t) {
ToastUtils.showToast(getApplicationContext(), "网络异常");
}
});
});
}
private void speak() {
findViewById(R.id.hello).setOnClickListener(v -> {
Call<AjaxJson> shout = NetConfig.create(ProjectApi.UserProject.class).speak("阿巴阿巴阿巴");
shout.enqueue(new CustomCallBack<AjaxJson>() {
@Override
public void response(Response<AjaxJson> response) {
ToastUtils.showToast(getApplicationContext(), Optional.ofNullable(response.body()).orElse(new AjaxJson()).getData());
}
@Override
public void failure(Throwable t) {
ToastUtils.showToast(getApplicationContext(), "网络异常");
}
});
});
}
private void login() {
findViewById(R.id.hello).setOnClickListener(v -> {
User user = new User("rubenHappyAchao", "Ruben8848");
Call<AjaxJson> shout = NetConfig.create(ProjectApi.UserProject.class).login(user);
shout.enqueue(new CustomCallBack<AjaxJson>() {
@Override
public void response(Response<AjaxJson> response) {
ToastUtils.showToast(getApplicationContext(), Optional.ofNullable(response.body()).orElse(new AjaxJson()).getMsg());
}
@Override
public void failure(Throwable t) {
ToastUtils.showToast(getApplicationContext(), "网络异常");
}
});
});
}
private void shout() {
findViewById(R.id.hello).setOnClickListener(v -> {
Call<AjaxJson> shout = NetConfig.create(ProjectApi.UserProject.class).shout();
shout.enqueue(new CustomCallBack<AjaxJson>() {
@Override
public void response(Response<AjaxJson> response) {
ToastUtils.showToast(getApplicationContext(), Optional.ofNullable(response.body()).orElse(new AjaxJson()).getMsg());
}
@Override
public void failure(Throwable t) {
ToastUtils.showToast(getApplicationContext(), "网络异常");
}
});
});
}
}
