前言
学习Retrofit2+RxJava时间不长,大概知道怎么用。根据需求简单的封装一下。
1.接口
public interface GankIO{
@GET("App/10/{index}")
Call getApp(@Path("index") String index);
}
@POST 请求方式
("819-1") URL地址
@QueryMap MapcityId 请求参数
ResponseBody 返回数据
2.网络请求类#
public class HttpManager {
public final static int CONNECT_TIMEOUT =5;
public final static int READ_TIMEOUT=5;
public final static int WRITE_TIMEOUT=5;
//服务器地址
private static final String BASE_URL = "";
private static Retrofit retrofit;
private static Retrofit getRetrofit() {
if (retrofit == null) {
//网络缓存路径文件
// File httpCacheDirectory = new File(BaseApplication.getInstance().getExternalCacheDir(), "responses");
//通过拦截器设置缓存,暂未实现
//CacheInterceptor cacheInterceptor = new CacheInterceptor();
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(CONNECT_TIMEOUT, TimeUnit.SECONDS)
.readTimeout(READ_TIMEOUT, TimeUnit.SECONDS)
.writeTimeout(WRITE_TIMEOUT, TimeUnit.SECONDS)
.addInterceptor(new MyInterceptors())
.build();
retrofit = new Retrofit.Builder()
.client(client)
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
}
return retrofit;
}
}
3.拦截器 MyInterceptors#
public class MyInterceptors implements Interceptor {
private static final String TAG = "MyInterceptors";
@Override
public Response intercept(Chain chain) throws IOException {
//封装headers
Request request = chain.request().newBuilder()
.addHeader("model","24037") //手机型号
.build();
Headers headers = request.headers();
//打印
System.out.println("phoneModel is : " + headers.get("phoneModel"));
String requestUrl = request.url().toString(); //获取请求url地址
String methodStr = request.method(); //获取请求方式
RequestBody body = request.body(); //获取请求body
String bodyStr = (body==null?"":body.toString());
//打印Request数据
Log.d(TAG, "intercept: Request Url is :" + requestUrl + "\nMethod is : " + methodStr + "\nRequest Body is :" + bodyStr + "\n");
Response response = chain.proceed(request);
if (response != null) {
//byte[] str = Base64.decode(response.body().string(), Base64.DEFAULT);
// s1 = Base64Decoder.decode(response.body().string());
//s1 = new String(str);
} else {
System.out.println("Respong is null");
}
Log.d(TAG, "intercept: response "+response.body().toString());
return response;
}
}
4.调用
Api.getRetrofit().create(GankIO.class).getApp(index).enqueue(new Callback() {
@Override
public void onResponse(Call call, Response response) {
//请求成功处理
}
@Override
public void onFailure(Call call, Throwable t) {
//请求失败处理
}
});
