前提：本文基于Retrofit + okhttp（下面代码可以直接复制使用！）
一、Retrofit常规使用如下：
OkHttpClient okHttpClient =new Builder()
.readTimeout(READ_TIME_OUT, TimeUnit.SECONDS)
.connectTimeout(CONNECT_TIME_OUT, TimeUnit.SECONDS)
.cache(new Cache(file, NET_CACHE_SIZE))
.cookieJar(new CookiesManager())
.addInterceptor(httpLoggingInterceptor)
.addNetworkInterceptor(new Interceptor() {
@Override
public Responseintercept(Chain chain)throws IOException {
Request original = chain.request();
Request.Builder rb = original.newBuilder();
rb.addHeader("token", filterValue(UserPref.getInstance().getToken()));
return chain.proceed(rb.build());
}
})
.build();
mService =new retrofit2.Retrofit.Builder()
.client(okHttpClient)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.baseUrl(baseUrl)
.build().create(ApiServer.class);
二、给http加密转https无证书需要添加如下代码
OkHttpClient okHttpClient =new Builder()
.sslSocketFactory(SSLSocketFactoryUtil.createSSLSocketFactory(), SSLSocketFactoryUtil.createTrustAllManager())
.hostnameVerifier(new SSLSocketFactoryUtil.TrustAllHostnameVerifier())
三、上面使用到的工具类SSLSocketFactoryUtil如下：
public class SSLSocketFactoryUtil {
/**
* @return
* init SSLSocketFactory
*/
public static SSLSocketFactorycreateSSLSocketFactory() {
SSLSocketFactory sslSocketFactory =null;
try {
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, new TrustManager[]{createTrustAllManager()}, new SecureRandom());
sslSocketFactory = sslContext.getSocketFactory();
}catch (Exception e) {
}
return sslSocketFactory;
}
/**
* @return
* init X509TrustManager
*/
public static X509TrustManagercreateTrustAllManager() {
X509TrustManager trustManager =null;
try {
trustManager =new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType){
//do nothing
}
public void checkServerTrusted(X509Certificate[] chain, String authType){
//do nothing
}
public X509Certificate[]getAcceptedIssuers() {
return new X509Certificate[0];
}
};
}catch (Exception e) {
}
return trustManager;
}
/**
* make TrustAllHostnameVerifier always true
*/
public static class TrustAllHostnameVerifierimplements HostnameVerifier {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
}
}
