HttpPost post = new HttpPost("https://....."); BasicHttpEntity paramEntity = new BasicHttpEntity(); paramEntity.setContent(new ByteArrayInputStream(json.getBytes("UTF-8"))); paramEntity.setContentLength(json.getBytes("UTF-8").length); paramEntity.setContentType("application/json"); // setHeader post.addHeader("Content-type","application/json"); // setEntity post.setEntity(paramEntity); // 执行请求并得到返回结果 HttpClient client = HttpClientUtils.client; HttpResponse response = client.execute(post); HttpEntity entity = response.getEntity();
