安卓okhttp的封装

现在我们项目中对okhttp的封装,跟大家分享一下.我们项目请求的时候是上传的json.后台解析.所有前段就很省事了.直接上代码

            

public classHttpOk {

   /**

     * 连接超时(默认：30秒)

     */

   public static intTimeOut=30;

   private staticOkHttpClient getHttpClient() {

        OkHttpClient client =newOkHttpClient();

        client.setConnectTimeout(TimeOut, TimeUnit.SECONDS);

       returnclient;

    }

   /**

     * 提交json 不检测更新

     *

     *@param url                   请求路径

    *@param requestBean     请求的json

     *@param cb                         回调

     *@param resultClass          返回的实体类型

     *@param tag                    用于区分网络请求

    */

   public static voidpostData(String url, Object requestBean, ACallOkHttp cb, Class<?> resultClass,inttag) {

       if(url.isEmpty()) {

           return;

        }

        Gson gson =newGson();

        String json = gson.toJson(requestBean);

        // LogUtils.i("请求的json="+ json);

        RequestBody formBody =newFormEncodingBuilder()

                .add("data", json)

                .build();

        Request request =newRequest.Builder()

                .url(url)

                .post(formBody)

                .build();

     //给回调返回的实体类

        cb.registerClass(resultClass, tag);

     //开始请求

        cb.onBeforeRequest(tag);

       getHttpClient().newCall(request).enqueue(cb);

    }

   /**

     * 提交json和图片,文本集合

     *

     *@param

    *@param cb

    */

   public static voidpost(String url, Object requestBean, Map<String, String> images, ACallOkHttp cb, Class<?> resultClass,inttag) {

        MultipartBuilder builder =newMultipartBuilder().type(MultipartBuilder.FORM);

       if(images !=null) {

           for(Map.Entry<String, String> entry : images.entrySet()) {

                builder.addFormDataPart(entry.getKey(), entry.getKey(),

                        RequestBody.create(MediaType.parse(guessMimeType(entry.getValue())),newFile(entry.getValue())));

            }

        }

        Gson gson =newGson();

        String json = gson.toJson(requestBean);

      //   LogUtils.d("请求的json", json);

        builder.addFormDataPart("data", json);

       //构建请求体

       RequestBody requestBody = builder.build();

       //构建请求

       Request request =newRequest.Builder()

                .url(url)//地址

               .post(requestBody)//添加请求体

               .build();

        cb.registerClass(resultClass, tag);

        cb.onBeforeRequest(tag);

       getHttpClient().newCall(request).enqueue(cb);

    }

   /**

     * 获取文件类型

     *@param path

    *@return

     */

   private staticString guessMimeType(String path) {

        FileNameMap fileNameMap = URLConnection.getFileNameMap();

        String contentTypeFor = fileNameMap.getContentTypeFor(path);

       if(contentTypeFor ==null) {

            contentTypeFor ="application/octet-scontentTypeFortream";

        }

       returncontentTypeFor;

    }

}

回调类,一个请求开始,请求失败,请求成功:

     

public abstract classACallOkHttp implementsCallback {

   private inttag=0;

   privateClass<?>resultClass=null;

    Handlerhandler=newHandler() {

       @Override

       public voidhandleMessage(Message msg) {

           super.handleMessage(msg);

           switch(msg.what) {

               case1:

                    onResultRequest(msg.arg1, msg.obj);

                   break;

               case2:

                    onErrorRequest(msg.arg1, (String) msg.obj);

                   break;

            }

        }

    };

   @Override

   public voidonFailure(Request request, IOException e) {

        Message message =newMessage();

        message.obj= e.getLocalizedMessage();

        message.arg1=tag;

        message.what=2;

       handler.sendMessage(message);

    }

   @Override

   public voidonResponse(Response response) {

        Gson gson =newGson();

        String json =null;

       try{

            json = response.body().string();

          //   LogUtils.i("返回来的结果="+ json);

            Object bean = gson.fromJson(json,resultClass);

            Message message =newMessage();

            message.obj= bean;

            message.arg1=tag;

            message.what=1;

           handler.sendMessage(message);

        }catch(IOException e) {

            e.printStackTrace();

            onErrorRequest(tag,"JSON解析失败!");

        }

    }

   public voidregisterClass(Class<?> resultClass,inttag) {

       this.resultClass= resultClass;

       this.tag= tag;

    }

   /**

     * 请求开始

     *

     *@param tag 标签

     */

   public abstract voidonBeforeRequest(inttag);

   /**

     * 请求成功

     *

     *@param tag  标签

     *@param bean 实体类对象

     */

   public abstract voidonResultRequest(inttag, Object bean);

   /**

     * 请求失败

     *

     *@param tag 标签

     *@param e   错误信息

     */

   public abstract voidonErrorRequest(inttag, String e);

用法:

     

ConsultAllJson allJson =newConsultAllJson();

     allJson.setPage(1);

     allJson.setSize(100);

 

HttpOk.post(HttpPathUtils.HTTP_URL,allJson,newACallOkHttp() {

   @Override

   public voidonBeforeRequest(inttag) {

         //开始请求,可以显示一个进度条,什么的

    }

    @Override

   public voidonResultRequest(int tag, Object bean) {

//成功之后直接强制一下,就拿到需要的实体类型了.

        ConsultAllJson consultAllJson = (ConsultAllJson) bean;
    }

    @Override
    public void onErrorRequest(inttag, String e) {

    }

},ConsultAllJson.class,1);

上传文本跟这个是一样的用法,就不写出来了.因为我们项目中只有psot请求,所有暂时也就写post请求,post上传文件,关于get请求,下载文件.会在下一章写出来.

   

                     以上只是我个人对okhttp的用法,如果有更好的可以一起指出来.一起探讨才能进步..
