Okhttp框架搭建及拦截器

来源：互联网发布：java工程师转行编辑：程序博客网时间：2024/05/19 01:30

本代码是由借鉴他人博客并加以改进所成

拦截器需要添加依赖：

compile 'com.squareup.okhttp3:logging-interceptor:3.9.0'

代码

public class OkhttpUtils {    //声明客户端    private OkHttpClient client;    //防止多个线程同时访问所造成的安全隐患    private volatile static OkhttpUtils utils;    //定义提交类型Json    private static final MediaType JSON = MediaType.parse("application/json;charset=utf-8");    //定义提交类型String    private static final MediaType STRING = MediaType.parse("text/x-markdown;charset=utf-8");    //子线程    private Handler handler;    //构造方法    private OkhttpUtils(){        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();        logging.setLevel(HttpLoggingInterceptor.Level.BODY);        client=new OkHttpClient.Builder()        .addInterceptor(logging)                .build();        handler=new Handler(Looper.getMainLooper());    }    //单例模式    public static OkhttpUtils getInstance(){        if(utils==null){            //线程同步锁            synchronized (OkhttpUtils.class){                if(utils==null){                    utils=new OkhttpUtils();                    utils=utils;                }            }        }        return utils;    }    //网络请求    public void syncJsonStringByUrl(String url, final FuncJsonString callback){        Request request=new Request.Builder().url(url).build();        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                Log.i("TAG", "解析失败");            }            @Override            public void onResponse(Call call, Response response) throws IOException {                if(response!=null&&response.isSuccessful()){                    OnSuccessJsonString(response.body().string(),callback);                }            }        });    }    //post提交表单数据    public void sendDataForClicent(String url, Map<String,String> params, final Class clazz, final FuncJsonString callback){        //表单对象，包含input开始的操作        FormBody.Builder from=new FormBody.Builder();        if(params != null && !params.isEmpty()){            for (Map.Entry<String,String> entry:params.entrySet()){                //装载表单值                from.add(entry.getKey(),entry.getValue());            }        }        RequestBody body=from.build();        //post提交        Request request=new Request.Builder().url(url).post(body).build();        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                Log.i("TAG", "解析失败");            }            @Override            public void onResponse(Call call, Response response) throws IOException {                if(response!=null&&response.isSuccessful()){                    Gson gson=new Gson();                    final BaseBean b= (BaseBean) gson.fromJson(response.body().string(),clazz);                    OnSuccessJsonString(b.code,callback);                }            }        });    }    //返回json字符串的接口    public interface FuncJsonString{        void onResponse(String result);    }    //请求的返回是json字符串    private void OnSuccessJsonString(final String jsonValue, final FuncJsonString callback){        handler.post(new Runnable() {            @Override            public void run() {                if(callback!=null){                    try {                        callback.onResponse(jsonValue);                    }catch (Exception e){                    }                }            }        });    }}
