如何使用java发送参数以@RequestBody类型接收到的请求。如下使用java的HttpClient写一个样例
依赖
<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore</artifactId><version>4.4.10</version> </dependency><dependency><groupId>commons-httpclient</groupId><artifactId>commons-httpclient</artifactId><version>3.1</version> </dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.6</version> </dependency>
1、接收部分代码
@RequestMapping("/test")public void getAccessToken(@RequestBody String jsonStr) {System.out.println("jsonStr:"+jsonStr);}
2、HttpClient发送的方法
public static String doPostRequestBody(String url, String jsonStr) {try {// 创建HttpClient实例HttpClient client = HttpClients.createDefault();// 创建HttpPost实例，指定URLHttpPost post = new HttpPost(url);// 设置请求头post.setHeader("Content-Type", "application/json; charset=UTF-8");post.setHeader("apiVersion", "v1");// 设置请求体StringEntity entity = new StringEntity(jsonStr, StandardCharsets.UTF_8);post.setEntity(entity);// 发送请求HttpResponse httpResponse = client.execute(post);// 获取响应输入流InputStream inStream = httpResponse.getEntity().getContent();BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "UTF-8"));String line = null;StringBuilder result = new StringBuilder();while ((line = reader.readLine()) != null) {result.append(line);}// 打印响应内容System.out.println("Response: " + result.toString());return result.toString();} catch (Exception e) {e.printStackTrace();}return null;}
3、等同于postMan中的调用
