51工具盒子所谓理解，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
|-------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 | hljs gradle 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
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 | hljs java 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 { /** * url */ 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();//使用 gson coverter，统一日期请求格式 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
|------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 | hljs java 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
|------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | hljs java 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(); /** * user/say?word= * @param word * @return */ @GET("user/say") Call<AjaxJson> say(@Query("word") String word); /** * user/say/xxx * @param word * @return */ @GET("user/say/{word}") Call<AjaxJson> speak(@Path("word") String word); /** * requestBody里{username:"xxx",password:"xxx"} * @param user * @return */ @POST("user/login") Call<AjaxJson> login(@Body User user); } } |
然后调用
