Spring Boot调用api post接口
示例
public static String sendPost(String url, JSONObject jsonObject) { log.info("请求地址:{}", url); String body = ""; // 创建httpclient对象 CloseableHttpClient client = HttpClients.createDefault(); CloseableHttpResponse response = null; // 创建post方式请求对象 HttpPost httpPost = new HttpPost(url); // 装填参数 StringEntity s = new StringEntity(jsonObject.toString(), "utf-8"); s.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json")); // 设置参数到请求对象中 httpPost.setEntity(s); log.info("请求参数:{}", jsonObject.toString()); // 设置header信息, 指定报文头【Content-type】 【User-Agent】 httpPost.setHeader("Content-type", "application/json"); httpPost.setHeader("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)"); try { // 执行请求操作,并拿到结果(同步阻塞) response = client.execute(httpPost); log.info("response 返回状态码:{}", response.getStatusLine().getStatusCode()); if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK){ // 获取结果实体 HttpEntity entity = response.getEntity(); if (entity != null) { // 按指定编码转换结果实体为String类型 body = EntityUtils.toString(entity, "utf-8"); log.info("响应body:", body); } // 关闭流 EntityUtils.consume(entity); }else{ log.error("response 返回状态码异常:{}", response.getStatusLine().getStatusCode()); } // 释放链接 response.close(); } catch (IOException e) { log.error("调用amf-sub api异常,{0}", e); e.printStackTrace(); } finally { if (client != null) { try { client.close(); } catch (IOException e) { log.error("关闭http client异常,{0}", e); e.printStackTrace(); } } if (response != null) { try { response.close(); } catch (IOException e) { log.error("关闭http response异常,{0}", e); e.printStackTrace(); } } } return body; }
