retrofit+gson+okhttp使用的简单记录

1.引用：

compile 'com.squareup.retrofit2:retrofit:2.1.0'      //retrofit2compile 'com.squareup.retrofit2:converter-gson:2.1.0'   //gson适配器compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'    //  rxjava适配器compile 'com.squareup.okhttp3:okhttp:3.3.1'        //okhttp

2.定义接口类：

 public interface WeatherApi {    @GET("onebox/weather/query?cityname=深圳")    Call<WeatherDataBean>  getWeather(@Query("key") String key);    @GET("index/")    Call<WeatherDataBean>  getWeather(@QueryMap Map<String ,String> params );}

3.编写解析类，gsonformat这个插件挺好用的：Mac下快捷键 ： command+N。

           private String date;            public String getTemperature() {                return temperature;            }            public void setTemperature(String temperature) {                this.temperature = temperature;

4.简单的基本路径和接口定义的拼接 get固定参数使用.
baseurl

Retrofit  retrofit=new Retrofit.Builder()        .baseUrl("http://gank.io/")        .addConverterFactory(GsonConverterFactory.create())        .build();GnakApi gnakApi=retrofit.create(GnakApi.class);Call<GnakBean>  call=gnakApi.getAndroidInfo();call.enqueue(new Callback<GnakBean>() {    @Override    public void onResponse(Call<GnakBean> call, Response<GnakBean> response) {        GnakBean.ResultsBean bean=response.body().getResults().get(0);        String result="<<"+bean.getImages()+"\n"+bean.getCreatedAt();        Log.i("result",result);        Toast.makeText(MainActivity.this,result,Toast.LENGTH_LONG).show();    }    @Override    public void onFailure(Call<GnakBean> call, Throwable t) {    }});

5.get动态参数

Retrofit  retrofit1=new Retrofit.Builder()        .baseUrl("http://op.juhe.cn/")        .addConverterFactory(GsonConverterFactory.create())        .build();WeatherApi  weatherApi=retrofit1.create(WeatherApi.class);   //124ac971e272bed4354d9c6b9b4e9de2Call<WeatherDataBean>  call1=weatherApi.getWeather("124ac971e272bed4354d9c6b9b4e9de2");call1.enqueue(new Callback<WeatherDataBean>() {    @Override    public void onResponse(Call<WeatherDataBean> call, Response<WeatherDataBean> response) {                WeatherDataBean.ResultBean  bean=response.body().getResult();               String  resultweather=bean.getToday().getTemperature()+"<<";        Log.i("result",resultweather);        Toast.makeText(MainActivity.this,resultweather,Toast.LENGTH_LONG).show();    }    @Override    public void onFailure(Call<WeatherDataBean> call, Throwable t) {    }});

6.get参数请求

Retrofit  retrofit2=new Retrofit.Builder()        .baseUrl("http://gank.io/")        .addConverterFactory(GsonConverterFactory.create())        .build();GnakApi gnakApi2=retrofit2.create(GnakApi.class);Call<GnakBean>  call2=gnakApi2.getAndroidInfo(10,1);call2.enqueue(new Callback<GnakBean>() {    @Override    public void onResponse(Call<GnakBean> call, Response<GnakBean> response) {        GnakBean.ResultsBean bean=response.body().getResults().get(0);        String result="<<"+bean.getImages()+"\n"+bean.getCreatedAt();        Log.i("result",result);        Toast.makeText(MainActivity.this,result,Toast.LENGTH_LONG).show();    }    @Override    public void onFailure(Call<GnakBean> call, Throwable t) {    }});

7.Get参数拼接

Retrofit retrofit3=new Retrofit.Builder()        .baseUrl("http://v.juhe.cn/weather/")      //http://v.juhe.cn/weather/index?format=2&        .addConverterFactory(GsonConverterFactory.create())        .build();WeatherApi weatherApi3=retrofit3.create(WeatherApi.class);Map<String ,String> params=new HashMap<>(); params.put("cityname","深圳");params.put("format","1");params.put("key","124ac971e272bed4354d9c6b9b4e9de2");Call<WeatherDataBean> call3=weatherApi3.getWeather(params);call3.enqueue(new Callback<WeatherDataBean>() {    @Override    public void onResponse(Call<WeatherDataBean> call, Response<WeatherDataBean> response) {            if (response.errorBody()==null){                WeatherDataBean.ResultBean  bean=response.body().getResult();                String  resultweather=bean.getToday().getTemperature()+"<<";                Log.i("result",resultweather);                Toast.makeText(MainActivity.this,resultweather,Toast.LENGTH_LONG).show();            }else {                Toast.makeText(MainActivity.this,response.errorBody().,Toast.LENGTH_LONG).show();            }    }    @Override    public void onFailure(Call<WeatherDataBean> call, Throwable t) {    }});
