asyncHttp 介绍
AsyncHttp
一款为android 网络请求的框架，采用最少的线程，基于AsyncPool 线程池实现的 http请求，支持 post和
get、delete等多种请求，实现请求任务和结果异步获取，支持初中高级开发人员各阶段的代码习惯。底层采用的是主线程管理工作线程的模式，并且维护了自己的请求队列，并且采取了任务的执行和结果的返回采取了不同的线程执行，所以更适用于批量网络请求
AsyncHttp 有哪些功能？
-
基本网络请求
-
文件下载（支持断点下载）
-
单线程下载
-
多线程下载
-
-
自定义头部请求信息
-
含有优先级，防止请求无反应
-
文件上传
使用方法
compile 'com.ml.asynchttp:asynchttp-android:1.0.7'
AsyncHttpUtils.init(new RequestInterceptorActionInterface() { @Override public <T> BaseHttpRequest<T> interceptorAction(BaseHttpRequest<T> baserequest) throws Exception { TelephonyManager tm = (TelephonyManager) BaseApplication.getInstance().getSystemService(Context.TELEPHONY_SERVICE); return baserequest;
}
}, new ResponseInterceptorActionInterface(){
);
LogUtils.setDebug(true);
-
参数1自定义请求处理拦截器，需要实现 RequestInterceptorActionInterface 接口
-
参数2是结果过滤器，可以自定义，只需要 实现 ResponseInterceptorActionInterface 接口
提示 ： 请求拦截器和过滤器可以在框架初始化添加，也可以在创建请求的时候，添加到请求中
普通网络请求
##### 常规写法 String url=Contents.baseURL+"user/"+ machineid +"/getDutyList.do"; Log.e("PaiBanActivity",url); AsyncHttpUtils.json(url, HttpMethod.Post, new HashMap<String, String>(), new JsonRequestLoadingCallback<PaiBanBean>(this) { @Override public void requestFail(Exception e, ResponseBody<String> request) {
e.printStackTrace();
showToast("网络出错,请重试");
} @Override public void requsetFinish() {
} @Override public void requsetStart() {
} @Override public void requestSuccess(PaiBanBean paiBanBean) { Log.e("PaiBanActivity",paiBanBean.toString() ); int status = paiBanBean.getStatus(); if (status==1) {
setPaiBan(paiBanBean);
}else {
showToast("获取数据失败,请重试");
}
}
});
##### 个性写法
###### 步骤一:定义相关的接口 public interface PathBeanTest { @JSONPOST("http://{ip}.26.106.136:8080/rest/common/user/login.do") public CProxyRequester test(@PathParam("ip")String ip, @Param("username")String username, @Param("password")String passwork ); @GET("http://{ip}.26.106.136:8080/rest/common/allFactorys.do") public CProxyRequester getAll(@PathParam("ip")String ip);
} *其中，方法注解包含有：JSONPOST POST GET DELETE PUT ....等 ，JSONPOST和POST无技术上差别，只是为了开发人员辨识清晰 *方法参数注解，包含两种，PathParam,Param ,PathParam表示匹配方法注解上的URL占位符，Param是请求的具体参数 ，注意：
例如上面的 {ip} 方法中@PathParam("ip")String ip 名称要对应 否则,请求失败
###### 步骤二:通过代理实例化接口 PathBeanTest t= ProxyCreater.creator(PathBeanTest.class);
###### 步骤三:设置结果处理线程级别
t.getAll("120").ResultMonitor(MIO.MainThread).Observation(new StringRequestResultCallBack<FactoryTestBean>() { @Override public void requestFail(Exception e, ResponseBody<String> request) {
} @Override public void requestSuccess(FactoryTestBean factoryTestBean) { Log.e("tag",factoryTestBean.getMsg()+" "+factoryTestBean.getData().getList().size());
} @Override public void requsetFinish() {
} @Override public void requsetStart() {
}
});
######MIO.MainThread表示主线程，MIO.IOThread 表示IO线程
文件的下载
写法一： String url="http://scimg.jb51.net/allimg/160815/103-160Q509544OC.jpg"; //必须设置存储路径 String filepath="C:\\Users\\admin\\Pictures\\Camera Roll\\img"+i+".jpg"; FileRequest resReques=new FileRequest(url);
resReques.setFilepath(filepath);
resReques.addHead(new Header("user-agent", "AsyHttp/1.0 ml"));
resReques.setRequestMethod(HttpMethod.Get); TaskHandler taskhandler= AsyncHttp.instance().download(resReques, new FileTest()); //可以调用 taskhandler.stop()方法取消任务 //FileTest 是 继承了 DownProgrossCallback<ResponseBody<T>>的 回掉接口，实现进度的监控，和结果的返回 }
写法二： AsyncHttpUtils.download("http://pic1.sc.chinaz.com/files/pic/pic9/201611/apic24088.jpg", "/sdcard/test/", "file.jpg", new DownProgrossCallback<ResponseBody<File>>() { @Override public void download_current(long current, long total) { Log.e("tag", "current=" + current + " total=" + total); int pr = (int) (current * 100.0 / total);
xiazai_pr.setProgress(pr);
} @Override public void start() { Toast.makeText(getApplication(), "开始下载", Toast.LENGTH_SHORT).show();
} @Override public void finish() { Toast.makeText(getApplication(), "完成", Toast.LENGTH_SHORT).show();
} @Override public void success(ResponseBody<File> result) { Toast.makeText(getApplication(), "成功下载" + result.getResult().getPath(), Toast.LENGTH_SHORT).show();
} @Override public void fail(Exception e, ResponseBody<File> request) {
e.printStackTrace(); Toast.makeText(getApplication(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
写法三： public interface DownloadTest { @DOWNLOAD("http://pic6.nipic.com/20100426/1687102_082357914928_2.jpg") public CProxyRequester<File> down(@Param String path);
} DownloadTest downloadTest=ProxyCreater.creator(DownloadTest.class);
downloadTest.down("/sdcard/test/file2.jpg").ResultMonitor(MIO.MainThread).Observation(new DownProgrossCallback<ResponseBody<File>>() { @Override public void download_current(long current, long total) {
} @Override public void start() {
} @Override public void finish() {
} @Override public void success(ResponseBody<File> result) {
} @Override public void fail(Exception e, ResponseBody request) {
}
});
多线程下载文件
String urls="http://img.taopic.com/uploads/allimg/130711/318756-130G1222R317.jpg"; String name=urls.substring(urls.lastIndexOf("/")+1,urls.length()); String filepath="C:\\Users\\admin\\Pictures\\Camera Roll\\"+name;
download s= new download(new RecordEntity(urls,filepath));
s.setTaskPriority(TaskPriority.LOWEST.getValue());//设置优先级 TaskHandler t= AsyncHttp.instance().download(s, new DownProgrossCallback<ResponseBody<RandomAccessFile>>() { @Override public void download_current(long current, long total) { // TODO Auto-generated method stub // System.out.println("当前 "+e+" current=="+current+" total="+total); } @Override public void fail(Exception e1,ResponseBody<RandomAccessFile> response) { // TODO Auto-generated method stub super.fail(e1,response); System.out.println("任务 "+ e+" ="+ Utils.getNowTime()+" e1="+e1.getMessage());
} @Override public void start() { // TODO Auto-generated method stub super.start(); System.out.println("任务 "+ e+" startTime="+ Utils.getNowTime());
} @Override public void finish() { // TODO Auto-generated method stub super.finish(); System.out.println("任务 "+ e+" endTime="+ Utils.getNowTime());
}
});
上传文件 (单线程)
#####一般写法1 String url="http://192.168.1.33:8080/StrutsDemo2/upload.action"; UploadRequest resReques=new UploadRequest(url);
resReques.addParam(new FileParamPart("upload", new File("C:\\Users\\admin\\Pictures\\Camera Roll\\img10.jpg"),Constents.TYPE_IMAGE));
resReques.setRequestMethod(HttpMethod.Post); AsyncHttp.instance().newRequest2(resReques, new uploadTest()); //uploadTest是 继承了 UploadProgrossCallback<ResponseBody<T>>的 回掉接口，实现进度的监控，和结果的返回 #####一般写法2 AsyncHttpUtils.upload("http://120.26.106.136:8080/rest/common/user/uploadAvatar.do", "/sdcard/test/test.jpg", "file", new UploadProgrossCallback<ResponseBody<String>>() { @Override public void upload_current(long current, long currentFileTotal, long total) { int pr = (int) (current * 100.0 / total); Log.e("tag", "current=" + current + " currentFileTotal= " + currentFileTotal + " total=" + total);
progressBar_shangchuan.setProgress(pr);
} @Override public void start() { Toast.makeText(getApplication(), "开始上传", Toast.LENGTH_SHORT).show();
} @Override public void finish() { Toast.makeText(getApplication(), "完成", Toast.LENGTH_SHORT).show();
} @Override public void success(ResponseBody<String> result) { Log.e("tag", result.getResult());
} @Override public void fail(Exception e, ResponseBody<String> request) { Toast.makeText(getApplication(), e.getMessage(), Toast.LENGTH_SHORT).show();
e.printStackTrace(); Log.e("tag", request.getResult());
}
});
#####个性写法 public interface UploadTest { @UPLOAD("http://120.26.106.136:8080/rest/common/user/uploadFile.do") public CProxyRequester<UploadResultBean> upload(@Param("file") String filepath);
} UploadTest uploadTest= ProxyCreater.creator(UploadTest.class);
uploadTest.upload("/sdcard/test/file.jpg").ResultMonitor(MIO.MainThread).Observation(new UploadRequestResultCallBack<UploadResultBean>(){ @Override public void upload_current(long current, long currentFileTotal, long total) { int pr = (int) (current * 100.0 / total); Log.e("tag", "current=" + current + " currentFileTotal= " + currentFileTotal + " total=" + total);
progressBar_shangchuan.setProgress(pr);
} @Override public void requestFail(Exception e, ResponseBody<String> request) {
e.printStackTrace();
} @Override public void requestSuccess(UploadResultBean uploadResultBean) { Log.e("tag",uploadResultBean.getMsg()); Toast.makeText(getApplicationContext(),uploadResultBean.getData().getName(),Toast.LENGTH_LONG).show();
} @Override public void requsetFinish() {
