工具介紹
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，復制okhttputils的源碼到項目中
封裝的功能
- 一般的get請求
- 一般的post請求
- 基於Http Post的文件上傳（類似表單）
- 文件下載/加載圖片
- 上傳下載的進度回調
- 支持取消某個請求
- 支持自定義Callback
- 支持HEAD、DELETE、PATCH、PUT
- 支持session的保持
- 支持自簽名網站https的訪問，提供方法設置下證書就行
<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 {
@Override
public void onCreate() {
super.onCreate();
//對於Https，框架中提供了一個類HttpsUtils，可設置為：可訪問所有的https網站、設置具體的證書、雙向認證
//同樣的，框架中只是提供了幾個實現類，你可以自行實現SSLSocketFactory，傳入sslSocketFactory方法中即可
HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(null, null, null);
//對於cookie，直接通過cookiejar方法配置，當然也可以自己實現CookieJar接口，編寫cookie管理相關代碼。
//對於持久化cookie，還可以使用https://github.com/franmontiel/PersistentCookieJar.相當於框架中只是提供了幾個實現類，你可以自行定制或者選擇使用
// 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)//
//對於Log，初始化OkhttpClient時，通過設置攔截器實現，框架中提供了一個LoggerInterceptor，當然你可以自行實現一個Interceptor
.addInterceptor(new LoggerInterceptor("TAG"))//
// .cookieJar(cookieJar)
.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
})//
.sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager)//
.build();
//默認情況下，將直接使用okhttp默認的配置生成OkhttpClient，如果有任何配置，記得在Application中調用initClient方法進行設置。
OkHttpUtils.initClient(okHttpClient);
