大家好，又见面了，我是你们的朋友全栈君。

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);
            }
        });

    }

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();
            }
        });
    }

下载显示进度条

//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();
            }
        });
    }

上传显示进度条

//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));
            }
        });
    }

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();
            }
        });
    }

1.自定义回调接口

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);
                            }
                        });
