封裝安卓的okhttp

標籤：ati   iss   user   col   1.2   build   square   failure   static   

1.封裝了get方法,handler更新主線程,回調的onsuccess,onfailure,onerror等方法

2.設定檔

api ‘com.android.support:recyclerview-v7:26.1.0‘api ‘com.squareup.okhttp3:okhttp:3.9.1‘//fastjsonapi ‘com.alibaba:fastjson:1.2.44‘

 

3.先建立一個http包，建BaseHttpCallback和OkHttpHelper這2個類，以後會加loading...這個東西

 

 

public class OkHttpHelper {    private static OkHttpClient okHttpClient;    private android.os.Handler handler;    private OkHttpHelper(){        okHttpClient =new OkHttpClient();        handler =new android.os.Handler(Looper.getMainLooper());    };    public static OkHttpHelper getInstance(){        return new OkHttpHelper();    }    public void get(String url,BaseHttpCallback baseHttpCallback){        Request request = buildRequest(url,null,HttpMethodType.GET);        doRequest(request, baseHttpCallback);    }    public void post(String url, Map<String,String>params,BaseHttpCallback baseHttpCallback){        Request request = buildRequest(url,null,HttpMethodType.POST);        doRequest(request, baseHttpCallback);    }    public void doRequest(final Request request, final BaseHttpCallback baseHttpCallback){        baseHttpCallback.onRequestBefore(request);        okHttpClient.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                callbackFailure(baseHttpCallback,e);            }            @Override            public void onResponse(Call call, Response response) throws IOException {                if(response.isSuccessful()){                    String s= response.body().string();                    callbackSuccess(baseHttpCallback,response,s);                }else{                    callbackError(baseHttpCallback,response,response.code());                }            }        });    }    private Request buildRequest(String url,Map<String,String> params,HttpMethodType methodType){        Request.Builder builder = new Request.Builder();        builder.url(url);        if(methodType==HttpMethodType.GET){            builder.get();        }else if(methodType==HttpMethodType.POST){        }        return builder.build();    }    enum HttpMethodType{        GET,        POST    }    private void callbackSuccess(final BaseHttpCallback callback, final Response response, final String s){        handler.post(new Runnable() {            @Override            public void run() {                callback.onSuccess(response,s);            }        });    }    private void callbackError(final BaseHttpCallback callback, final Response response, final int code){        handler.post(new Runnable() {            @Override            public void run() {                callback.onError(response,code,null);            }        });    }    private void callbackFailure(final BaseHttpCallback callback, final Exception e){        handler.post(new Runnable() {            @Override            public void run() {                callback.onFailure(e);            }        });    }}

public abstract class BaseHttpCallback {    public abstract void onRequestBefore(Request request);    public abstract void onSuccess(Response response,String string);    public abstract void onError(Response response,int code,Exception e);    public abstract void onFailure(Exception e);}

4. 還另外封裝了個User類

public class User {    public String result;    public List<Data> data;    public class Data{        public String name;        public String age;        public String getName() {            return name;        }        public String  getAge() {            return age;        }    }    public String getResult() {        return result;    }    public List<Data> getDatas() {        return data;    }}

 

5.activity中調用例子

OkHttpHelper httpHelper  =OkHttpHelper.getInstance(); String url = "http://www.baidu.com";        httpHelper.get(url,new BaseHttpCallback(){            @Override            public void onRequestBefore(Request request) {            }            @Override            public void onSuccess(Response response, String string) {            }            @Override            public void onError(Response response, int code, Exception e) {            }            @Override            public void onFailure(Exception e) {                Toast.makeText(MainActivity.this,"當前網路不可用,請檢查網路",Toast.LENGTH_LONG).show();            }        });

 

6.未完善的，沒有post，沒有loading效果,
