Android 对okhttp的封装

不废话，需求：根据服务器API封装网络请求，怎么办？

简单封装okhttp的get,post，put,delete请求：

        PersistentCookieJar cookieJar = new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(getApplicationContext()));        HttpUtils.okHttpClient = new OkHttpClient.Builder()                .cookieJar(cookieJar)                .build();

   /**     * 为HttpGet 的 url 方便的添加多个name value 参数。     *     * @param url     * @param params     * @return     */    public static String attachHttpGetParams(String url, LinkedHashMap params) {        Iterator keys = params.keySet().iterator();        Iterator values = params.values().iterator();        StringBuffer stringBuffer = new StringBuffer();        stringBuffer.append("?");        for (int i = 0; i < params.size(); i++) {            String value = null;            try {                value = URLEncoder.encode(values.next(), "utf-8");            } catch (Exception e) {                e.printStackTrace();            }            stringBuffer.append(keys.next() + "=" + value);            if (i != params.size() - 1) {                stringBuffer.append("&");            }        }        return url + stringBuffer.toString();    }    public static void HTTP_GET_IMPROVE(final String url, final HTTPInterface httpInterface, final int count) {        Request request = builder.url(url).method("GET", null).build();        //3.创建一个call对象,参数就是Request请求对象        Call call = okHttpClient.newCall(request);        //4.请求加入调度，重写回调方法        call.enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                httpInterface.onFailure(call, e);

               }            }        });    }    public static void HTTP_POST_IMPROVE(final String url, RequestBody requestBody, final HTTPInterface httpInterface, final int count) {        //1.创建OkHttpClient对象//        OkHttpClient okHttpClient = new OkHttpClient();

               }            }        });    }    public static void HTTP_PUT_IMPROVE(final String url, RequestBody requestBody, final HTTPInterface httpInterface, final int count) {        //1.创建OkHttpClient对象//        OkHttpClient okHttpClient = new OkHttpClient();

               }            }        });    }    public static void HTTP_DELETE_IMPROVE(final String url, RequestBody requestBody, final HTTPInterface httpInterface, final int count) {        //1.创建OkHttpClient对象//        OkHttpClient okHttpClient = new OkHttpClient();

           }            @Override            public void onResponse(Call call, Response response) throws IOException {                int code = response.code();                int myCount = count - 1;                if (code != 200 && count > 0) {                    HTTP_GET_IMPROVE(url, httpInterface, myCount);                } else {                    httpInterface.onResponse(call, response);                }            }        });    }    /**     */    public static void HTTPUploadImage(final String url, final String imagePath, final HTTPInterface httpInterface, final int count) {        Log.e("imagePath", "HTTPUploadImage " + imagePath);        File file = new File(imagePath);        RequestBody image = RequestBody.create(MediaType.parse("image/png"), file);        RequestBody requestBody = new MultipartBody.Builder()                .setType(MultipartBody.FORM)                .addFormDataPart("files", imagePath, image)                .build();        Request request = new Request.Builder()                .url(url)                .post(requestBody)                .build();        Call call = okHttpClient.newCall(request);        call.enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {            }            @Override            public void onResponse(Call call, Response response) throws IOException {                int code = response.code();                int myCount = count - 1;                if (code != 200 && count > 0) {                    HTTPUploadImage(url, imagePath, httpInterface, myCount);                } else {                    httpInterface.onResponse(call, response);                }            }        });    }

根据服务器的API封装：

  public static void outProduct(String token, String product_id, HttpUtils.HTTPInterface httpInterface) {        RequestBody requestBody = new FormBody.Builder()                .add("token", token)                .add("product_id", product_id)                .build();        String url = HttpUtils.OUT_PRODUCT;        HttpUtils.HTTP_POST_IMPROVE(url, requestBody, httpInterface, HttpUtils.HTTP_TOTAL_COUNT);    }

这样的好处是网络请求的API与具体的界面分离了，我之前写代码，每次写完界面，再做界面的请求，导致很多界面有同样的网络请求，不停复制，修改代码，浪费时间。封装代码也是一个程序员技术提升的体现。
