Android OkHttpClient的get和post的同步和异步请求

OkHttpClient的依赖

implementation 'com.squareup.okhttp3:okhttp-ws:3.4.2'

日志拦截器的依赖

implementation 'com.squareup.okhttp3:logging-interceptor:3.12.0'

//同步处理get方式 必须放在子线程里

private void sendNet() {
    new Thread(new Runnable() {
        @Override
        public void run() {

            try {
                //1:学什么都能new出一个对象来
                OkHttpClient okHttpClient = new OkHttpClient();
                //Request就是请求的类
                Request request = new Request.Builder().url(mUrl).build();
                //发送请求newCall方法
                Call call = okHttpClient.newCall(request);
                //通过call去处理给你响应Response
                Response response = call.execute();
                //从相应体里面拿到数据
                String string = response.body().string();
                Log.e("string", string);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

//同步处理POST方式

private void sendPost() {
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                //1:学什么都能new出一个对象来
                OkHttpClient okHttpClient = new OkHttpClient();
                //创建请求体
                RequestBody requestBody = new FormBody.Builder()
                        .add("mobile", "18513426687")//键值对的形式
                        .build();
                //Request就是请求的类
                Request request = new Request.Builder().url(mPostUrl).post(requestBody).build();
                //发送请求newCall方法
                Call call = okHttpClient.newCall(request);
                //通过call去处理给你响应Response
                Response response = call.execute();
                final String string = response.body().string();
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
                    }
                });
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

//异步的Get方式

    private void asyncSend() {
        OkHttpClient okHttpClient = new OkHttpClient();
        final Request request = new Request.Builder().url(mUrl).build();
        Call call = okHttpClient.newCall(request);
        //异步处理
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Log.e("onFailure", "onFailure");
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final String string = response.body().string();
//                Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
                //一个小知识 不建议使用 在子线程直接刷新UI操作
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });
    }

//异步POST

private void asyncPost() {
    OkHttpClient okHttpClient = new OkHttpClient();

    RequestBody body = new FormBody.Builder()
            .add("mobile", "18513426687")
            .add("password", "123456").build();
    //链式调用
    Request request = new Request.Builder().url(mPostUrl).post(body).build();
    okHttpClient.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, IOException e) {
            Log.e("onFailure", "onFailure");
        }

        @Override
        public void onResponse(Call call, Response response) throws IOException {
            final String string = response.body().string();
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
                }
            });
        }
    });
}

OkHttpClient的封装类，可以将这些全部封装起来

public class OkUtils {
    private OkHttpClient okHttpClient;

    private OkUtils() {
        //日志拦截器
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        okHttpClient = new OkHttpClient.Builder()
                .connectTimeout(20, TimeUnit.SECONDS)//响应时间，读取时间
                .readTimeout(20, TimeUnit.SECONDS)
                .callTimeout(20, TimeUnit.SECONDS)
                .addInterceptor(loggingInterceptor)//添加日志拦截器
                .build();
    }

    //静态内部类单例模式
    public static OkUtils getInstance() {
        return OkHolder.okUtils;
    }

    static class OkHolder {
        private static final OkUtils okUtils = new OkUtils();
    }

    //这是同步的get和post
    public String getSync(String url) throws IOException {
        Request request = new Request.Builder().url(url).build();
        return okHttpClient.newCall(request).execute().body().string();
    }

    public String postSync(String url, String key, String value) throws IOException {
        RequestBody body = new FormBody.Builder().add(key, value).build();
        Request request = new Request.Builder().url(url).post(body).build();
        return okHttpClient.newCall(request).execute().body().string();
    }

    //异步的get和post

    public void getAsync(String url, Callback callback) {
        Request request = new Request.Builder().url(url).build();
        okHttpClient.newCall(request).enqueue(callback);
    }

    public void postAsync(String url, Callback callback) {
        RequestBody body = new FormBody.Builder().add("key", "value").build();
        Request request = new Request.Builder().url(url).post(body).build();
        okHttpClient.newCall(request).enqueue(callback);
    }
}
