Retrofit+Rxjava 网络请求的完美封装（二）（观察者模式）
上一篇是Retrofit+Rxjava简单封装，是在MainActivity中构建的请求体，这篇博文是将请求体Request也置入到Rxjava中
Retrofit+Rxjava 网络请求的简单封装（一）（观察者模式）
如果想对RxJava进行简单的了解，可以参考我如下的博文
RxJava响应式编程之初级了解
如果相对Retrofit进行简单的了解学习，可以参考我如下的博文
Retrofit简单封装使用–Post请求封装请求体、Get请求通过参数、map方式构建url
我通过公司一个上线App接口来进行Retrofit+Rxjava 的简单学习
http://x-phone.cn/api/v1.0/DeletePrivateContact当然你直接访问上面的url是无法获取服务器Json数据的，因为是需要封装请求体，如下是在没有封装请求体，返回的错误界面
Method Not Allowed
The method is not allowed for the requested URL.
首先看下请求的Json格式如下
[getJuheResult]requestJsonStr =
{
"contact_ids": [
"1475920950100"
],
"godin_id": "4c59396301ab6274bd7892f0b31df36e",
"imei": "123456789012345",
"phone_num": "18612185929"
}返回的Json格式如下，如下是一种返回的格式：
[getJuheResult.onNext]Head{statuscode='000009', statusmsg='device and user not match'}
这篇博客就对上篇博客的进行Retrofit+Rxjava 简单封装在进行请求体的封装
首先看看上篇博客在MainActivity中封装的HttpRequest请求
ArrayList contact_ids = new ArrayList<>();
contact_ids.add("1475920950100");
HttpRequest httpRequest = new HttpRequest();
httpRequest.setPhone_num("18612185929");
httpRequest.setImei("123456789012345");
httpRequest.setGodin_id("4c59396301ab6274bd7892f0b31df36e");
httpRequest.setContact_ids(contact_ids); 封装之后呢？在上篇博客中，在通过参数传递进来
public void postClickAppInfoParameterJsonBody(HttpRequest request) {
if (request == null) {
throw new NullPointerException("Argument request cannot be null.");
}
Log.d(TAG,"[getJuheResult]requestJsonStr = \n"+gson.toJson(jsonParser.parse(gson.toJson(request))));
FactoryInters.PostClickAppInfoParameterJsonBody server = retrofit.create(FactoryInters.PostClickAppInfoParameterJsonBody.class);
//观察者
Subscriber subscriber = new HttpResultSubscriber("getJuheResult");
server.getJuheResult(request)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(subscriber);
}如上的方式，其实我们可以将它也放到Rxjava中封装起来，通过Rxjava直接传递进来
1、在Rxjava中构建HttpRequest进行传递或者根据业务需要进行转换（当然如果请求业务多了，可以另起一个类统一管理）
/**
* 设置线程
*/
public Observable setThread(Observable observable) {
observable.subscribeOn(Schedulers.from(exector))
.observeOn(AndroidSchedulers.mainThread());
return observable;
}
/**
* 上传服务器删除联系人操作
*/
public void postClickAppInfoParameterJsonBody() {
//被观察者。。。
RxJavaHelper.getInstance().setThread(Observable.create(new Observable.OnSubscribe() {
@Override
public void call(Subscribersuper HttpRequest> subscriber) {
ArrayList contact_ids = new ArrayList<>();
contact_ids.add("1475920950100");
HttpRequest httpRequest = new HttpRequest();
httpRequest.setPhone_num("18612185929");
httpRequest.setImei("123456789012345");
httpRequest.setGodin_id("4c59396301ab6274bd7892f0b31df36e");
httpRequest.setContact_ids(contact_ids);
subscriber.onNext(httpRequest);
}
}))
.subscribe(new Action1() {
@Override
public void call(HttpRequest request) {
RetrofitManger.getInstance().postClickAppInfoParameterJsonBody(request);
}
});
} 2、将HttpRequest传递过来之后，就开始进行Retrofit方面的封装首先看基类RetrofitBase
protected RetrofitBase(){
retrofit = new Retrofit.Builder()
.baseUrl(BASEURL)
.client(client())
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
}
private OkHttpClient client(){
LauncherTrust launcherTrust = new LauncherTrust();
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.connectTimeout(TIMEOUT, TimeUnit.MILLISECONDS)
.readTimeout(TIMEOUT,TimeUnit.MILLISECONDS)
.sslSocketFactory(sslSocketFactory(launcherTrust),launcherTrust)
.hostnameVerifier(new AllowAllHostnameVerifier())
.build();
return okHttpClient;
}3、我们看下Retrofit通过特有的注解方式，配置请求HttpRequest，返回HttpResult的代码接口，跟Rxjava结合起来，然后在第4步操作中，通过Rxjava的观察者模式进行响应操作
public interface FactoryInters {
//http://x-phone.cn/api/v1.0/DeletePrivateContact
interface PostClickAppInfoParameterJsonBody{
@Headers({"Content-Type: application/json","Accept: application/json"})
@POST("DeletePrivateContact")
Observable<HttpResult> getJuheResult(@Body HttpRequest request);
}
}4、然后看Retrofit主类，主要处理请求返回数据的传递，异步响应操作
/**
* {"phone_num": "18612185929", "imei": "123456789012345", "godin_id": "4c59396301ab6274bd7892f0b31df36e", "contact_ids": ["1475920950100"]}
*/
public void postClickAppInfoParameterJsonBody(HttpRequest request) {
if (request == null) {
throw new NullPointerException("Argument request cannot be null.");
}
Log.d(TAG,"[getJuheResult]requestJsonStr = \n"+gson.toJson(jsonParser.parse(gson.toJson(request))));
FactoryInters.PostClickAppInfoParameterJsonBody server = retrofit.create(FactoryInters.PostClickAppInfoParameterJsonBody.class);
//观察者
Subscriber subscriber = new HttpResultSubscriber("getJuheResult");
server.getJuheResult(request)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(subscriber);
}
private class HttpResultSubscriber extends Subscriber<HttpResult>{
private String method;
public HttpResultSubscriber(String methodTag){
this.method = methodTag;
}
@Override
public void onCompleted() {
Log.i(TAG, "onCompleted");
}
@Override
public void onError(Throwable e) {
StringBuffer sb = new StringBuffer();
sb.append("[").append(method).append(".onError]").append(e);
Log.e(TAG,sb.toString());
}
@Override
public void onNext(HttpResult httpResult) {
StringBuffer sb = new StringBuffer();
sb.append("[").append(method).append(".onNext]")
.append(httpResult.getHead().toString());
Log.i(TAG,sb.toString());
}
}如下的代码，就是Rxjava观察者模式的使用，就是通过传递HttpRequest，获取HttpResult结果，然后在通过构建被观察者，观察者进行事件传递，响应操作和处理
server.getJuheResult(request)
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(subscriber);最后再次看下请求体，响应结果如下：
11-03 14:48:23.526 31285-31285/? D/RetrofitManger: [getJuheResult]requestJsonStr =
{
"contact_ids": [
"1475920950100"
],
"godin_id": "4c59396301ab6274bd7892f0b31df36e",
"imei": "123456789012345",
"phone_num": "18612185929"
}
11-03 14:48:23.758 31285-31285/? I/RetrofitManger: [getJuheResult.onNext]Head{statuscode='000009', statusmsg='device and user not match'}纠错
/**
* 设置线程
*/
public Observable setThread(Observable observable) {
observable.subscribeOn(Schedulers.from(exector))
.observeOn(AndroidSchedulers.mainThread());
return observable;
} 这个经过测试，是运行在主线程的，应该将其拿出来，放到分线程中
