摘要：
它可以用多种方式书写。
//关于http 须要两个jar包 httpclient-4.0.jar httpcore-4.0.1.jar
private static final HttpClient httpClient = new DefaultHttpClient();
try {
//获得密匙库
KeyStore trustStore = KeyStore.getInstance("jks");
String keyStoreFile = "xxxxx.keystore";
String keyPwd = "xxxxxxx";
FileInputStream instream = new FileInputStream(new File(keyStoreFile));
//密匙库的password
trustStore.load(instream, keyPwd.toCharArray());
//注冊密匙库
SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
//不校验域名
socketFactory.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme sch = new Scheme("https", socketFactory, 443);
httpClient.getConnectionManager().getSchemeRegistry().register(sch);
} catch (Exception e) {
e.printStackTrace();
}
//以下这段是调用代码。能够有非常多种写法。不局限于用HttpPost
HttpPost httpPost = new HttpPost( url );
StringEntity entity = new StringEntity(params);
entity.setContentEncoding("UTF-8");
httpPost.setEntity( entity );
//发送请求
HttpResponse response = httpClient.execute( httpPost );
String jsonStr = EntityUtils.toString( response.getEntity() );
