使用方法(很简单有木有)
showLoading();
Map<String, String> map = new ArrayMap<>(); map.put("key1", "value1"); map.put("key2", "value2"); map.put("key3", "value3");
addDispose(RxNet.request(ApiManager.getInstance().getCat(map), new RxNetCallBack<List<CatBean>>() {
@Override public void onSuccess(List<CatBean> data) {
hideLoading();
showToast("获取信息成功" + data.get(0).toString());
}
@Override public void onFailure(String msg) {
hideLoading();
showToast(msg);
}
}));它是怎么实现的呢？
(一)RxNet(有三种请求方式，很据需求可增加比如上传、下载):
1：返回数据带有body
{code:"200",
msg:"请求成功",
pwd:"*******"}2：返回数据没有body
{code:"200",
msg:"请求成功"}3：请求返回错误请求码（-1表示请求失败）
{code:"201",
msg:"修改失败"}核心代码如下：
/**
* 一般请求，返回数据带有body
*/
public static <T> Disposable request(Observable<BaseResponse<T>> observable, final RxNetCallBack<T> callBack) { return observable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.onErrorReturn(new Function<Throwable, BaseResponse<T>>() { @Override
public BaseResponse<T> apply(Throwable throwable) {
callBack.onFailure(ExceptionHandle.handleException(throwable)); return null;
}
})
.subscribe(new Consumer<BaseResponse<T>>() { @Override
public void accept(BaseResponse<T> tBaseResponse) { if (tBaseResponse.getCode().equals("200")) {
callBack.onSuccess(tBaseResponse.getData());
} else {
callBack.onFailure(tBaseResponse.getMsg());
}
}
}, new Consumer<Throwable>() { @Override
public void accept(Throwable throwable) {
AppLogUtil.printE("请求错误:" + throwable.getMessage());
}
});
} /**
* 返回数据没有body
*/
public static Disposable requestWithoutBody(Observable<BaseResponse> observable, final RxNetCallBack<String> callBack) { return observable.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.onErrorReturn(new Function<Throwable, BaseResponse>() { @Override
public BaseResponse apply(Throwable throwable) {
callBack.onFailure(ExceptionHandle.handleException(throwable)); return null;
}
})
.subscribe(new Consumer<BaseResponse>() { @Override
public void accept(BaseResponse baseResponse) { if (baseResponse.getCode().equals("200")) {
callBack.onSuccess(baseResponse.getMsg());
} else {
callBack.onFailure(baseResponse.getMsg());
}
}
}, new Consumer<Throwable>() { @Override
public void accept(Throwable throwable) {
AppLogUtil.printE("请求错误:" + throwable.getMessage());
}
});
} /**
* 请求返回错误请求码
* -1表示请求失败
*/
public static <T> Disposable requestForCode(Observable<BaseResponse<T>> observable, final RxNetCallBackForCode<T> callBack) { return observable
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.onErrorReturn(new Function<Throwable, BaseResponse<T>>() { @Override
public BaseResponse<T> apply(Throwable throwable) { // -1表示请求失败
callBack.onFailure("-1", ExceptionHandle.handleException(throwable)); return null;
}
})
.subscribe(new Consumer<BaseResponse<T>>() { @Override
public void accept(BaseResponse<T> tBaseResponse) { if (tBaseResponse.getCode().equals("200")) {
callBack.onSuccess(tBaseResponse.getData());
} else {
callBack.onFailure(tBaseResponse.getCode(), tBaseResponse.getMsg());
}
}
}, new Consumer<Throwable>() { @Override
public void accept(Throwable throwable) {
AppLogUtil.printE("请求错误:" + throwable.getMessage());
}
});
} /**
* 下载和上传
*/（二）实现Retrofit2的全局请求单例
public class ApiManager { private Retrofit client; private ApiManager() {
client = new Retrofit.Builder()
.baseUrl(AppConstants.Base_Url_Test)
.client(initClient())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.build();
} private static volatile AppApi INSTANCE; public static AppApi getInstance() { if (INSTANCE == null) { synchronized (ApiManager.class) { if (INSTANCE == null) {
INSTANCE = new ApiManager().getAppApi();
}
}
} return INSTANCE;
} private AppApi getAppApi() { return client.create(AppApi.class);
} private static OkHttpClient initClient() {
OkHttpClient.Builder builder = new OkHttpClient.Builder(); //声明日志类
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() { @Override
public void log(String message) {
AppLogUtil.printE(message);
}
}); //设定日志级别
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY); //延时
builder.addInterceptor(httpLoggingInterceptor) //设置参数加密
//.addInterceptor(new EncryptParamInterceptor())
.connectTimeout(10, TimeUnit.SECONDS)
.readTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS); return builder.build();
}
}ps:参数加密的步骤：拦截带有请求参数的请求，对参数进行加密后 ，重新组装成请求体，再进行请求,
核心代码如下：
**
* 加密请求参数
*/public class EncryptParamInterceptor implements Interceptor { @Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request();
Map<String, String> mapForJson = new ArrayMap<>(); if (request.method().equals("GET")) { for (int i = 0; i < request.url().querySize(); i++) {
mapForJson.put(request.url().queryParameterName(i), request.url().queryParameterValue(i));
}
} else if (request.method().equals("POST") && (request.body() instanceof FormBody)) {
FormBody oldFormBody = (FormBody) request.body(); for (int i = 0; i < oldFormBody.size(); i++) {
mapForJson.put(oldFormBody.name(i), oldFormBody.value(i));
}
}
Gson gson = new Gson();
String json = gson.toJson(mapForJson);
String pwdText = null; try { //这里是你自己的加密方式(和后台人员商定)
// pwdText = AESUtil.encrypt(json);
pwdText = "****************";
} catch (Exception e) {
e.printStackTrace();
} //防止服务器"+"被编码成空格
if (!TextUtils.isEmpty(pwdText)) {
pwdText = pwdText.replace("+", "%2B");
}
FormBody.Builder bodyBuilder = new FormBody.Builder();
FormBody formBody;
formBody = bodyBuilder
.addEncoded("param", handlePwdTextXx(pwdText))
.build();
Request newRequest = request.newBuilder()
.post(formBody)
.build(); return chain.proceed(newRequest);
} /**
* 处理密文中的0x 0X
* 防止解密失败
*/
private static String handlePwdTextXx(String pwdText) { if (TextUtils.isEmpty(pwdText)){ return "";
} if (pwdText.contains("0x")) {
pwdText = pwdText.replace("0x", "0x");
} if (pwdText.contains("0X")) {
pwdText = pwdText.replace("0X", "0X");
} return pwdText;
}
}(三)addDispose()方法
先看代码：
@SuppressLint("Registered")public class BaseActivity extends AppCompatActivity implements BaseView { //........................
//添加当前类名(lin.frameapp.xxx)的dispose
public void addDispose(Disposable disposable) {
RxDisposeManager.get().add(getClass().getName(), disposable);
} @Override
protected void onDestroy() { super.onDestroy(); //移除dispose
RxDisposeManager.get().cancel(getClass().getName());
} //........................}用RxDisposeManager去管理每个请求的disposable，在适当的时候去dispose，防止内存泄露
RxDisposeManager也是用单例实现：
public class RxDisposeManager { private static volatile RxDisposeManager sInstance = null; private ArrayMap<Object, Disposable> maps; public static RxDisposeManager get() { if (sInstance == null) { synchronized (RxDisposeManager.class) { if (sInstance == null) {
sInstance = new RxDisposeManager();
}
}
} return sInstance;
} private RxDisposeManager() {
maps = new ArrayMap<>();
} public void add(Object tag, Disposable disposable) {
maps.put(tag, disposable);
} public void remove(Object tag) { if (!maps.isEmpty()) {
maps.remove(tag);
}
} public void removeAll() { if (!maps.isEmpty()) {
maps.clear();
}
} public void cancel(Object tag) { if (maps.isEmpty()) { return;
} if (maps.get(tag) == null) { return;
} if (!maps.get(tag).isDisposed()) {
maps.get(tag).dispose();
maps.remove(tag);
}
} public void cancelAll() { if (maps.isEmpty()) { return;
}
Set<Object> keys = maps.keySet(); for (Object apiKey : keys) {
cancel(apiKey);
}
}
}
