http发送post请求，发送参数为实体

public static String post(JSONObject json, String url) {
String result = “”;
HttpPost post = new HttpPost(url);
try {
CloseableHttpClient httpClient = HttpClients.createDefault(); post.setHeader(“Content-Type”, “application/json;charset=utf-8”); post.addHeader(“Authorization”, “Basic YWRtaW46”);
StringEntity postingString = new StringEntity(json.toString(), “utf-8”); post.setEntity(postingString);
HttpResponse response = httpClient.execute(post);
InputStream in = response.getEntity().getContent(); BufferedReader br = new BufferedReader(new InputStreamReader(in, “utf-8”));
StringBuilder strber = new StringBuilder();
String line = null;
while ((line = br.readLine()) != null) {
strber.append(line + ‘\n’); }
br.close();
in.close(); result = strber.toString(); if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
result = “服务器异常”; } } catch (Exception e) { System.out.println(“请求异常”);
throw new RuntimeException(e);
} finally { post.abort(); }
return result; }

EntityDto dto= new EntityDto ();
dto.setUname(“哈哈”);
dto.setAge(18);
dto.setSalary(12000);
String response = HttpUtil2.post((JSONObject) JSONObject.toJSON(autoTestDto), autoTestUrl);
