HTTPClient调用https请求，通过基本认证用户名密码（Basic Auth）

public static void http() throws Exception {
JSONObject obj = new JSONObject();
obj.put("param", "paramValue");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(AuthScope.ANY,
new UsernamePasswordCredentials(userName, password));
CloseableHttpClient createDefault = HttpClients.custom()
.setDefaultCredentialsProvider(credsProvider)
.build();
HttpPost post = new HttpPost(url);
StringEntity entity = new StringEntity(obj.toString(),"utf-8");
entity.setContentEncoding("UTF-8");
entity.setContentType("application/json");

post.setEntity(entity);
CloseableHttpResponse result = createDefault.execute(post);
int statusCode = result.getStatusLine().getStatusCode();
System.out.println(statusCode);
System.out.println("result：" + EntityUtils.toString(result.getEntity()));
}

//下面是正常http请求，直接发送json格式的作为参数传到服务器

HttpPost post = new HttpPost(url);//post.setHeader("Content-Type","application/json;charset=utf-8");StringEntity entity = new StringEntity(obj.toString(),"utf-8");entity.setContentEncoding("UTF-8");entity.setContentType("application/json");post.setEntity(entity);CloseableHttpClient createDefault = HttpClients.createDefault();CloseableHttpResponse result = createDefault.execute(post);String responseMsg = EntityUtils.toString(result.getEntity(),"UTF-8"));
