在Java中使用JSON进行HTTP POST

这是你需要做的：

1. 获取Apache HttpClient，这将使你能够发出所需的请求
2. 使用它创建一个HttpPost请求，并添加标题“ application / x-www-form-urlenpred”
3. 创建一个StringEntity，将JSON传递给它
4. 执行通话

代码大致看起来像（你仍然需要对其进行调试并使之正常工作）

//Deprecated//HttpClient httpClient = new DefaultHttpClient(); HttpClient httpClient = HttpClientBuilder.create().build(); //Use this instead try {    HttpPost request = new HttpPost("http://yoururl");    StringEntity params =new StringEntity("details={"name":"myname","age":"20"} ");    request.addHeader("content-type", "application/x-www-form-urlenpred");    request.setEntity(params);    HttpResponse response = httpClient.execute(request);    //handle response here...}catch (Exception ex) {    //handle exception here} finally {    //Deprecated    //httpClient.getConnectionManager().shutdown(); }
