String proxyHost = "代理host";
final String username = "";
final String password = "";
Authenticator proxyAuthenticator = new Authenticator() {
	  @Override public Request authenticate(Route route, Response response) throws IOException {
		   String credential = Credentials.basic(username, password);
		   return response.request().newBuilder()
			   .header("Proxy-Authorization", credential)

	};

OkHttpClient okHttpClient = new OkHttpClient.Builder()  
		.connectTimeout(JDCommonConstant.TIME_OUT, TimeUnit.SECONDS)  
		.readTimeout(JDCommonConstant.TIME_OUT, TimeUnit.SECONDS)  
		.proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort)))
		.proxyAuthenticator(proxyAuthenticator)
		.build();
