Okhttp的简单使用

引入包:implementation 'com.squareup.okhttp3:okhttp:4.9.0'

//建议与单例模式一起使用，此处不做延伸

//1.创建客户端
okHttpClient = new OkHttpClient.Builder()
        //.sslSocketFactory(TrustAllCerts.createSSLSocketFactory(), TrustAllCerts.getX509TrustManager()) https协议才需要ssl
        //.hostnameVerifier(new TrustAllCerts.TrustAllHostnameVerifier())
        .connectTimeout(10, TimeUnit.SECONDS)
        .readTimeout(500, TimeUnit.SECONDS).build();
