Android OkHttp简单封装

一、浅辄OkHttp

Okhttp现在来说应该算很厉害的网络请求的框架了。
当然，这也是拾人牙慧，我特么第三方框架都用上了还管什么拾人牙慧。

开搞！！！！！

推荐个鸿洋大神的http://blog.csdn.net/lmj623565791/article/details/49734867

1. 一般的get请求
2. 一般的post请求
3. 文件上传(如：头像、背景图片等)
4. 文件下载(如：APK) 待更…

1、一般的GET请求

先上一个回调接口，只有两个简单的方法;

/**
 * @auther Fsnzzz
 * @date 2018.11.20
 * @param onSucceed() ： 成功回调
 * @param onFailure() ： 失败回调 
 */
public interface NetCallBack {
    void onSucceed(Response response);
    void onFailure(String msg);
}

同步get请求

    /**
   	 * call.execute();
     * 同步GET请求   因为是耗时操作，要在子线程里执行 new Thread(new Runnable())
     * @param url 请求链接
     * @param netCallBack
     * @throws IOException
     */
    private void onSyncGet(String url,NetCallBack netCallBack) throws IOException {
   		 //创建okHttpClient对象
		OkHttpClient mOkHttpClient = new OkHttpClient();
        Request request = new Request.Builder()
                .get()//默认get,可省略
                .url(url)
                .build();
        Call call = mOkHttpClient.newCall(request);
        //请求加入调度
        Response response = call.execute();
        netCallBack.onSucceed(response);
        // response.body().string();
    }
    

异步get请求

   /**
     * On async get. 异步GET请求
     * call.enqueue()
     * @param netCallBack the net call back
     * @author Fsnzzz
     */
    private void onAsyncGET(String url, final NetCallBack netCallBack) {
   		 //创建okHttpClient对象
		OkHttpClient mOkHttpClient = new OkHttpClient();
        Request request = new Request.Builder()
                .get()//默认get,可省略
                .url(url)
                .build();
        Call call = mOkHttpClient.newCall(request);
        //请求加入调度
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
            	// 请求失败的回调
                netCallBack.onFailure(e.getMessage().toString());
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
            	//成功的回调
                netCallBack.onSucceed(response);
                 // response.body().string();
            }
        });
    }

2、一般post请求

回调的接口还是那个接口

	public interface NetCallBack {
 	   void onSucceed(Response response);
 	   void onFailure(String msg);
}

同步post请求 带参

 /**
     * 同步POST请求 
     * @param url
     * @param bodyParams 
     * @return
     */
    private Response onSyncPostBody(String url, Map<String,String> bodyParams) throws IOException {
        RequestBody body = getBodyParams(bodyParams);
        Request.Builder builder = new Request.Builder();
        Request request = builder.post(body)
                .url(url)
                .build();
        Call call = mOkHttpClient.newCall(request);
        //请求加入调度
        Response response = call.execute();
        return response;
    } 

  /**
     * 设置bodyParams
     * @param bodyParams
     * @return RequestBody
     */
    private RequestBody getBodyParams(Map<String,String> bodyParams){
        RequestBody body = null;
        FormBody.Builder formBody = new FormBody.Builder();
        if (bodyParams != null){
            Iterator<String> iterator = bodyParams.keySet().iterator();
            String key = "";
            while (iterator.hasNext()){
                key = iterator.next().toString();
                formBody.add(key,bodyParams.get(key));
            }
        }
        return formBody.build();
    }

post请求的时候是要携带参数的，参数是包含在请求体中的；所以我们通过FormBody.Builder。添加多个String键值对，然后去构造RequestBody，最后完成我们Request的构造。

异步post请求带参

  /**
     * 异步post请求
     * @param url
     * @param bodyParams
     */
    
    private void onAsyncPOST_Body(String url,Map<String,String> bodyParams,NetCallBack netCallBack){
        Request.Builder builder = new Request.Builder();
        Request request = builder.post(getBodyParams(bodyParams))
                .url(url)
                .build();
        Call call = mOkHttpClient.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                netCallBack.onFailure(e.getMessage());
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                netCallBack.onSucceed(response);
            }
        });
    }

3、图片上传

由于公司后台给的接口不需要进行传参，所有图片上传到同一个后台文件夹内，上传成功后返回一个图片链接，然后再把图片链接上传到相关的后台。

    /**
     * 图片上传  不带参数的上传，
     * @param url
     * @param body
     * @param imgs
     * @param netCallBack
     */
    public void onUpImage(String url, JSONObject data,NetCallBack netCallBack){
        MultipartBody.Builder builder = new MultipartBody.Builder();
        if (data != null){
            Iterator<String> keys = data.keys();
            while (keys.hasNext()){
                File file = null;
                try {
                    String key = keys.next();
                    file = new File(data.getString(key));
                    builder.addFormDataPart(key, file.getAbsolutePath(), RequestBody.create(MediaType.parse("multipart/form-data"), file));
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }
        
        builder.setType(MultipartBody.FORM);
        MultipartBody multipartBody = builder.build();
        Request request = new Request.Builder()
                .url(url)
                .post(multipartBody)
                .build();
        mOkHttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                netCallBack.onFailure(e.getMessage());
            }
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                netCallBack.onSucceed(response);
            }
        });

    }
