工具介绍
使用:
- AndroidStudio:【compile 'com.squareup.okhttp3:okhttp:3.4.2'】和【compile 'com.zhy:okhttputils:2.6.2'】和【compile 'com.google.code.gson:gson:2.3.1'】
- eclipse:添加okthttp、okio、gson的jar包,复制okhttputils的源码到项目中
封装的功能
- 一般的get请求
- 一般的post请求
- 基于Http Post的文件上传(类似表单)
- 文件下载/加载图片
- 上传下载的进度回调
- 支持取消某个请求
- 支持自定义Callback
- 支持HEAD、DELETE、PATCH、PUT
- 支持session的保持
- 支持自签名网站https的访问,提供方法设置下证书就行
<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />android:name="com.bqt.okhttp.MyApplication"
Application
public class MyApplication extends Application {@Overridepublic void onCreate() {super.onCreate();//对于Https,框架中提供了一个类HttpsUtils,可设置为:可访问所有的https网站、设置具体的证书、双向认证//同样的,框架中只是提供了几个实现类,你可以自行实现SSLSocketFactory,传入sslSocketFactory方法中即可HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(null, null, null);//对于cookie,直接通过cookiejar方法配置,当然也可以自己实现CookieJar接口,编写cookie管理相关代码。//对于持久化cookie,还可以使用https://github.com/franmontiel/PersistentCookieJar.相当于框架中只是提供了几个实现类,你可以自行定制或者选择使用// ClearableCookieJar cookieJar = new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(getApplicationContext()));// CookieJarImpl cookieJar = new CookieJarImpl(new MemoryCookieStore());OkHttpClient okHttpClient = new OkHttpClient.Builder()//.connectTimeout(10000L, TimeUnit.MILLISECONDS)//.readTimeout(10000L, TimeUnit.MILLISECONDS)////对于Log,初始化OkhttpClient时,通过设置拦截器实现,框架中提供了一个LoggerInterceptor,当然你可以自行实现一个Interceptor.addInterceptor(new LoggerInterceptor("TAG"))//// .cookieJar(cookieJar).hostnameVerifier(new HostnameVerifier() {@Overridepublic boolean verify(String hostname, SSLSession session) {return true;}})//.sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager)//.build();//默认情况下,将直接使用okhttp默认的配置生成OkhttpClient,如果有任何配置,记得在Application中调用initClient方法进行设置。OkHttpUtils.initClient(okHttpClient);}}
