首先写getSslsf()方法：
private static SSLConnectionSocketFactory getSslsf() throws NoSuchAlgorithmException, KeyManagementException {
SSLContext sslContext = SSLContext.getInstance("SSL");//sslContext= SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
/*Registry<ConnectionSocketFactory> reg = RegistryBuilder.<ConnectionSocketFactory> create()
.register("http", PlainConnectionSocketFactory.INSTANCE).register("https", sslsf).build();
*/
return sslsf;
}
再次创建HttpClients.custom().setSSLSocketFactory(getSslsf()).build()的httpClient;
CloseableHttpClient httpClient = null;
HttpPost httpPost = null;
try {
httpClient = HttpClients.custom().setSSLSocketFactory(getSslsf()).build();//实例化HttpClients对象
RequestConfig requestConfig = RequestConfig.custom()
.setSocketTimeout(20000).setConnectTimeout(20000).build();//构建RequestConfig对象
httpPost = new HttpPost(url);//构建HttpPost对象
httpPost.setConfig(requestConfig);//设置RequestConfig
/**
* 在请求正文中，可以随意的提交一段字符串给服务器，现在为了数据交换的统一性，所以大家都是提交的一段json串
* 所以body的数据格式{"name":"zhangsan","age":18},如果body是该数据格式，则Content-Type要设置为application/json
* new StringEntity(body)是指利用body构建一个请求正文对象，且StringEntity是支持Content-Type为application/json的，
* 所以，如果用StringEntity对象且body的数据为json串，则无需我们再设置Content-type
*/
httpPost.setHeader("Content-Type","application/json");//setHeader是设置请求头，该句代码是设置Content-Type，要设置其它的请求头,也是setHeader方法
httpPost.setHeader("Connection","keep-alive");
httpPost.setEntity(new StringEntity(body));//设置请求正文，也就是设置json串
// httpPost.setEntity(new StringEntity(body,"application/x-www-form-urlencoded"));//同上面两句代码一个意思
//SSLSocketFactory.getSocketFactory().setHostnameVerifier(new AllowAllHostnameVerifier());
//SSLConnectionSocketFactory sslFactory = new SSLConnectionSocketFactory(sslContext,SSLConnectionSocktFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
CloseableHttpResponse response = httpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();//获取响应正文对象
String result = EntityUtils.toString(httpEntity,"utf-8");
System.out.println("***"+result);
return result;//按编码输出响应正文
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if(httpPost !=null){
httpPost.releaseConnection();
}
if(httpClient !=null){
httpClient.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return null;
