OKGO

一. get请求

public void getString(){ OkGo.<String>get("http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1").execute(new StringCallback() { @Override public void onSuccess(Response<String> response) { String body = response.body(); Toast.makeText(MainActivity.this, ""+body, Toast.LENGTH_SHORT).show(); } @Override public void onError(Response<String> response) { super.onError(response); } }); }

二.post请求

//post请求数据 public void dopost(){ HashMap<String, String> map = new HashMap<>(); map.put("phone","18233790750"); map.put("passwd","345"); OkGo.<String>post("https://www.apiopen.top/createUser?key=00d91e8e0cca2b76f515926a36db68f5&").params(map).execute(new StringCallback() { @Override public void onSuccess(Response<String> response) { Toast.makeText(MainActivity.this, ""+response.body(), Toast.LENGTH_SHORT).show(); } }); }

三.下载文件显示进度条

//get下载文件 public void getFile(){ OkGo.<File>get("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4") .execute(new FileCallback("/sdcard/","aaaaa.mp4") { @Override public void onSuccess(Response<File> response) { File body = response.body(); } @Override public void onStart(Request<File, ? extends Request> request) { super.onStart(request); } @Override public void downloadProgress(Progress progress) { super.downloadProgress(progress); //progress.fraction 获得当前上传进度 范围0-1 bar.setProgress((int) (progress.fraction*100)); } @Override public void onError(Response<File> response) { super.onError(response); } @Override public void onFinish() { super.onFinish(); } }); }

四.上传文件显示进度条

//post上传文件 private void upload() { OkGo.<String>post("http://172.21.79.88/hfs/").isMultipart(true).params("file",new File("/sdcard/来自天堂的魔鬼.mp3"),"ass.mp3") .execute(new StringCallback(){ @Override public void onSuccess(Response<String> response) { Toast.makeText(MainActivity.this, ""+response.body(), Toast.LENGTH_SHORT).show(); } @Override public void uploadProgress(Progress progress) { super.uploadProgress(progress); //progress.fraction 获得当前上传进度 范围0-1 bar.setProgress((int) (progress.fraction*100)); } }); }

五.请求图片

//get请求图片 public void getBitmap(){ OkGo.<Bitmap>get("https://ss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=486958716,243120904&fm=26&gp=0.jpg").execute(new BitmapCallback() { @Override public void onSuccess(Response<Bitmap> response) { Bitmap bitmap = response.body(); Toast.makeText(MainActivity.this, ""+bitmap.getByteCount(), Toast.LENGTH_SHORT).show(); } }); }

六.okGo简单的json封装

public abstract class JsonCallBack<T> extends AbsCallback<T> { private Type type; private Class clazz; public JsonCallBack(Type type) { this.type = type; } public JsonCallBack(Class t) { this.clazz = t; } public JsonCallBack() { } /** * 该方法是子线程处理，不能做ui相关的工作 * 主要作用是解析网络返回的 response 对象，生成onSuccess回调中需要的数据对象 */ @Override public T convertResponse(Response response) throws Throwable { ResponseBody body = response.body(); if (body == null) return null; T data = null; Gson gson = new Gson(); String string = body.string(); if (type != null) data = (T) gson.fromJson(string , type); if (clazz != null) data = gson.fromJson(string , clazz); return data; } }

2.使用

OkGo.<Cai>get("http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1") .execute(new JsonCallBack<Cai>(Cai.class) { @Override public void onSuccess(Response<Cai> response) { Cai body = response.body(); Log.d("cai", "onSuccess: "+body); } });
