内容包括

这个一个封装好的 okhttp 的库，里面包含了如下：

get方法，可以添加参数
封装好的Gson
下载图片，再自定义图片大小进行压缩后存储
下载文件，并显示进度
多线程下载文件，并显示进度
post发送 key - value
post 发送字符串或者json
post 发送文件，并显示上传进度
post 发送表单，变显示上传进度

2 、怎么使用

Download

Step 1、 Add the JitPack repository in your root build.gradle at the end of repositories:

    allprojects {        repositories {            ...            maven { url 'https://jitpack.io' }        }    }

Step 2. Add the dependency

dependencies {            compile 'com.github.LillteZheng:okhttplib:v1.1'    }

3、初始化

 OkHttpClient okHttpClient = new OkHttpClient.Builder()                    .readTimeout(TIME_OUT, TimeUnit.SECONDS)                    .connectTimeout(TIME_OUT, TimeUnit.SECONDS)                    .writeTimeout(TIME_OUT+TIME_OUT,TimeUnit.SECONDS)                    .cookieJar(new PersistentCookieJar(new SetCookieCache(),new SharedPrefsCookiePersistor(this)))                    .build();        mClient = OkHttpCommonClient.getInstance();        mClient.setOkhttpClient(okHttpClient);

基本使用：

//使用get方法获取数据，        mClient.getBuilder()                .url(Weather_baseurl)                .putParams("key","m9datavogh53ftie")                .putParams("location","shenzhen")                .builder()                .enqueue(new StringResponse() { //使用不同的 response                    @Override                    public void onSuccess(String response) { //返回你需要的值，比如这里的String，或者json等等                        Log.d(TAG, "builder: "+response);                    }                    @Override                    public void onFailure(Object errorObj) {                    }                });

Gson

mClient.getBuilder()                .url(gsonurl)                .builder()                //在这里把json的实体类写在这里即可，比如我的root.class                .enqueue(new JsonResponse(Root.class) { //这里的颜色区域是 jdk1.5的警告，                                                        // 因为用的是泛型,直接关掉即可。                    @Override                    public void onSuccess(Object response) {                        Root root = (Root) response;                        Log.d(TAG, "onSuccess: "+root.getContent());                    }                    @Override                    public void onFailure(Object errorObj) {                    }                });

图片

 mClient.getBuilder()                .url(imgurl)                .builder()                .enqueue(new BitmapResponse(230,150) { //这里可以设置图片的大小，不写则下载原始图片                    @Override                    public void onSuccess(Bitmap response) {                        img.setImageBitmap(response);                    }                    @Override                    public void onFailure(Object errorObj) {                        Log.d(TAG, "onFailure: "+errorObj.toString());                    }                });

文件下载，单线程：

 String path = Environment.getExternalStorageDirectory().getPath();        mClient.getBuilder()                .url(fileurl)                .builder()                .enqueue(new FileResponse(fileurl,path) {                    @Override                    public void onProgress(int progress) {                        Log.d(TAG, "onProgress: "+progress);                    }                    @Override                    public void onSuccess(String response) {                        Log.d(TAG, "onSuccess: "+response);                    }                    @Override                    public void onFailure(Object errorObj) {                        Log.d(TAG, "onFailure: "+errorObj.toString());                    }                });

文件下载，多线程

String path = Environment.getExternalStorageDirectory().getPath();        mClient.getBuilder()                .url(fileurl)                .builder()                .enqueue(new FileMultResponse(fileurl,path,3) {                    @Override                    public void onProgress(int progress) {                        Log.d(TAG, "onProgress: "+progress);                    }                    @Override                    public void onSuccess(String response) {                        Log.d(TAG, "onSuccess: "+response);                    }                    @Override                    public void onFailure(Object errorObj) {                        Log.d(TAG, "onFailure: "+errorObj.toString());                    }                });

4、 post 方法

基本使用

 mClient.postBuilder()                .url(BASEURL+"login")                .putParams("username","zhengshaorui")                .putParams("password","123456789")                .builder()                .enqueue(new StringResponse() {                    @Override                    public void onSuccess(String response) {                        Log.d(TAG, "onSuccess: "+response);                    }                    @Override                    public void onFailure(Object errorObj) {                        Log.d(TAG, "onFailure: "+errorObj.toString());                    }                });

post String

 mClient.postStringBuilder()                .url(BASEURL+"getString")                .addMedieType("text/plain;chaset-utf-8","{username:rachel,password:123}")                .builder()                .enqueue(new StringResponse() {                    @Override                    public void onSuccess(String response) {                    }                    @Override                    public void onFailure(Object errorObj) {                    }                });

Post File 显示上传进度

File file = new File(Environment.getExternalStorageDirectory(),"TvHouseManager.apk");        if (!file.exists()){            Toast.makeText(this, "TvHouseManager.apk" + "文件不存在", Toast.LENGTH_SHORT).show();            return;        }        mClient.postFileBuilder()                .url(BASEURL+"getFile")                .addMedieType("application/vnd.android.package-archive",file)                .builder()                .enqueue(new StringResponse() {                    @Override                    public void onSuccess(String response) {                    }                    @Override                    public void onFailure(Object errorObj) {                    }                    @Override                    public void onUploadProgress(int progress) {                        super.onUploadProgress(progress);                        Log.d(TAG, "onUploadProgress: "+progress);                    }                });

Post form 也显示上传进度

File file = new File(Environment.getExternalStorageDirectory(),"tvlog.jpg");        if (!file.exists()){            Toast.makeText(this, "tvlog.jpg" + "文件不存在", Toast.LENGTH_SHORT).show();            return;        }        mClient.postUploadFile()                .url(BASEURL+"UpdateInfo")                .addFile("mPic","mTestPhone.jpg",file)                .addPart("username","zhengshaorui")                .addPart("password","10086")                .builder()                .enqueue(new StringResponse() {                    @Override                    public void onSuccess(String response) {                    }                    @Override                    public void onFailure(Object errorObj) {                    }                    @Override                    public void onUploadProgress(int progress) {                        super.onUploadProgress(progress);                        Log.d(TAG, "onUploadProgress: "+progress);                    }                });
