Java读取数据POST内容类型application / x-www-form-urlencoded _读取数据

时人不识凌云木，直待凌云始道高。这篇文章主要讲述Java读取数据POST内容类型application / x-www-form-urlencoded相关的知识，希望能为你提供帮助。
我有一个我正在测试的API。 API接收POST请求并像这样读取它

StringBuffer jb = new StringBuffer(); String line = null; try { BufferedReader reader = request.getReader(); while ((line = reader.readLine()) != null) jb.append(line); System.out.println("jb: "+jb); System.out.println("request.getHeader('content-type'): "+request.getHeader("content-type")); } catch (Exception e) { /*report an error*/ }

当我在“application / json; charset = utf-8”中发送POST请求时，一切正常

httpPost.setHeader("content-type", "application/json; charset=utf-8");

它打印这个：

jb: {"client_domain":"=....); //proper Json data request.getHeader('content-type'): application/json; charset=utf-8

我可以正确地读取数据。
但是我的问题是当我以相同的方式发送数据但我设置了内容类型“application / x-www-form-urlencoded; charset = utf-8”

httpPost.setHeader("content-type", "application/x-www-form-urlencoded; charset=utf-8");

测试是相同的只是内容类型不同但似乎我不再收到任何数据：

jb: request.getHeader('content-type'): application/x-www-form-urlencoded; charset=utf-8

任何的想法？
///更新
这是Spring Controller

@RequestMapping(value = https://www.songbingjia.com/android/{"user/add"}, method = RequestMethod.POST, produces="application/json; charset=utf-8") @ResponseBody public ResponseEntity< String> getNewUserApi(HttpServletRequest request, HttpServletResponse response) throws Exception {Map< String, Object> jsonObj = new HashMap< String, Object> (); StringBuffer jb = new StringBuffer(); String line = null; try { BufferedReader reader = request.getReader(); while ((line = reader.readLine()) != null) jb.append(line); System.out.println("jb: "+jb); System.out.println("request.getHeader('content-type'): "+request.getHeader("content-type")); } catch (Exception e) { /*report an error*/ } ///I create my JSon that will be sent back return JsonUtils.createJson(jsonObj);

//更新2以下是我发送数据的方式

public static void main(String[] args) throws Exception {String url = "http://localhost:8080/child/apiv1/user/add"; CloseableHttpClient client = HttpClientBuilder.create().build(); HttpPost httpPost = new HttpPost(url); httpPost.setHeader("content-type", "application/x-www-form-urlencoded; charset=utf-8"); try { //we had to the parameters to the post request JSONObject json = new JSONObject(); json.put("client_id", "fashfksajfhjsakfaskljhflakj"); json.put("client_secret", "9435798243750923470925709348509275092"); json.put("client_domain", "dummy.localhost.com"); //create the user json object JSONObject userObj = new JSONObject(); userObj.put("email", "johnsmith42@yopmail.com"); userObj.put("name", "Anna Sax"); JSONArray childrenArray = new JSONArray(); JSONObject child1 = new JSONObject(); child1.put("name", "Iphone 6"); child1.put("age", "2"); childrenArray.put(child1); userObj.put("children", childrenArray); json.put("user", childObj); StringEntity params = new StringEntity(json.toString()); httpPost.setEntity(params); System.out.println("executing request: " + httpPost.getRequestLine()); HttpResponse response; response = client.execute(httpPost); //[...]} //End main

我知道创建一个Json并将其发送到“application / x-www-form-urlencoded”并没有多大意义，但只是我们的一个用户无法解决他的问题，它只会发送“application /的X WWW窗体-urlencoded”。
答案【Java读取数据POST内容类型application / x-www-form-urlencoded】@RequestMapping的'produce'属性显示客户端只能接受application / json数据，因此您可以删除它或将其更改为'application / x-www-form-urlencoded'。
