用Retrofit做GET请求,在onResponse()里面怎么才能获取到返回的JSON数据呢?

[202005021116]

这个URL是可以正常访问的.打印出来的是对象地址值,我已经toString了. 也不能调用response.body.string方法.
1.NetWork.class

public class NetWork {
    private static Retrofit retrofit;
    /**返回Retrofit*/
    public static Retrofit getRetrofit(){
        if(retrofit==null){
            Retrofit.Builder builder = new Retrofit.Builder();//创建Retrfit构建器
            retrofit = builder.baseUrl("http://v.juhe.cn/") //指定网络请求的baseUrl
//            retrofit = builder.baseUrl("http://v.juhe.cn/") //指定网络请求的baseUrl
                    .addConverterFactory(GsonConverterFactory.create())//返回的数据通过Gson解析
                    .build();
        }
        return retrofit;
    }
}

2.NetInterface.class

public interface NetInterface {
//    @GET("mobile/get")
    @GET("toutiao/index?type=top&key=c727cca6fb450ea08b4b0fa220b72eb1")
//    @GET("toutiao/index")
    Call<Bean> getDatas();
}

3.Bean.class

public class Bean {

    private String reason;
    public String phone;
    public String key;
    private String error_code;

    public String getError_code() {
        return error_code;
    }

    public void setError_code(String error_code) {
        this.error_code = error_code;
    }

    public String getReason() {
        return reason;
    }

    public void setReason(String reason) {
        this.reason = reason;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }
}

4.MainActivity.class

    private void doTest() {
        //初始化Retrofit,加载接口
        NetInterface netInterface = NetWork.getRetrofit().create(NetInterface.class);
        netInterface.getDatas()
                .enqueue(new Callback<Bean>() {
                    @Override
                    public void onResponse(Call<Bean> call, Response<Bean> response) {
                        //请求成功
                        Bean bean = response.body();
                        String json = response.body().toString();
                        Log.d(TAG, "2336=   " + json);//这里打印的是com.b.demo8.Bean@8463c78
                        String reason = bean.getReason();
                        String error_code = bean.getError_code();
//                                Log.d(TAG, "2319=   "+reason);
//                                String message = response.message();
//                                Log.d(TAG, "2327=   "+message);
//                                Log.d(TAG, "2312=   "+error_code);
//                                Log.d(TAG, "2304=   "+json);
                    }

                    @Override
                    public void onFailure(Call<Bean> call, Throwable t) {
                        //请求失败
                        Log.d(TAG, "onFailure: ");
                    }
                });
    }

Retrofit在创建的时候可以设置Gson自动转啊，https://blog.csdn.net/haveferrair/article/details/51499274
