代码示例

 1 　　@Test
 2     public void test09() throws IOException {
 3         String requestUrl = "xxxxx";
 4         CloseableHttpClient httpClient = HttpClients.createDefault();
 5         HttpPost httpPost = new HttpPost(requestUrl);
 6         Person person = new Person("强强", "19");
 7         StringBody stringBody = new StringBody(JSONObject.toJSONString(person), ContentType.APPLICATION_JSON);
 8 
 9         MultipartEntityBuilder builder = MultipartEntityBuilder.create();
10         builder.setCharset(Consts.UTF_8); // 设置编码
11         builder.setContentType(ContentType.create("multipart/form-data", Consts.UTF_8)); // 传递文件
12         builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); // 设置浏览器的模式(否则文件名乱码)
13 
14         // 对于普通的表单字段如果含有中文的话，不能通过addTextBody，否则乱码s
15         builder.addBinaryBody("files",
16                 new FileInputStream(new File("强强.txt")),
17                 ContentType.MULTIPART_FORM_DATA,
18                 "强强.txt");
19         builder.addPart("person", stringBody);
20         HttpEntity build = builder.build();
21         httpPost.setEntity(build);
22         CloseableHttpResponse response = httpClient.execute(httpPost);
23         HttpEntity entity = response.getEntity();
24         if (HttpStatus.SC_OK == response.getStatusLine().getStatusCode()) {
25             System.out.println("请求成功！");
26             for (Header header : response.getAllHeaders()) {
27                 System.out.println(header.getName() + "  " + header.getValue());
28 
29             }
30         }
31         // 确保流关闭
32         EntityUtils.consume(entity);
33         response.close();
34         httpClient.close();
35     }
