Okhttp的Github：[https://github.com/square/okhttp][https_github.com_square_okhttp]

导入依赖

implementation 'com.squareup.okhttp3:okhttp:3.5.0'

创建OkHttpClient

OkHttpClient okHttpClient = new OkHttpClient();

创建请求

Request request = new Request.Builder()
                    .get()
                    .url("http://某服务器地址/HOME_URL.json")
                    .build();

Call call = okHttpClient.newCall(request);

用enqueue这一个

call.enqueue(new okhttp3.Callback() {
                @Override
                public void onFailure(okhttp3.Call call, IOException e) {
                    Toast.makeText(getActivity(), "请检查网络连接", Toast.LENGTH_SHORT).show();
                }
    
                @Override
                public void onResponse(okhttp3.Call call, okhttp3.Response response) throws IOException {
                    Start start = new Gson().fromJson(response.body().string(), Start.class);
    
                }
            });
        }

基本用Okhttp请求就这些

看下具体的代码

OkHttpClient okHttpClient = new OkHttpClient();
            Request request = new Request.Builder()
                    .get()
                    .url("http://某服务器地址/HOME_URL.json")
                    .build();
    
            okhttp3.Call call = okHttpClient.newCall(request);
    
            call.enqueue(new okhttp3.Callback() {
                @Override
                public void onFailure(okhttp3.Call call, IOException e) {
                    Toast.makeText(getActivity(), "请检查网络连接", Toast.LENGTH_SHORT).show();
                }
    
                @Override
                public void onResponse(okhttp3.Call call, okhttp3.Response response) throws IOException {
                    Start start = new Gson().fromJson(response.body().string(), Start.class);//这里是解析
    
                }
            });
        }

别忘了加上网络权限    <uses-permission android:name="android.permission.INTERNET"/>
