从Android应用程序发送到nodejs服务器通过HTTP发送后，我的JSON看起来不同
当我试图通过HTTP发送一个JSON作为一个string到一个nodejs服务器，当我试图loggingrequest.body它看起来不同，我不能访问任何领域。
我的类发送请求到服务器：
public class SendData extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... strings) { String data = ""; HttpURLConnection httpURLConnection = null; try{ httpURLConnection = (HttpURLConnection)new URL(strings[0]).openConnection(); httpURLConnection.setRequestMethod("POST"); httpURLConnection.setDoOutput(true); DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream()); wr.writeBytes(strings[1]); wr.flush(); wr.close(); InputStreamReader inputStreamReader = new InputStreamReader(httpURLConnection.getInputStream()); int inputStreamData = inputStreamReader.read(); while (inputStreamData != -1){ char current = (char) inputStreamData; inputStreamData = inputStreamReader.read(); data += current; } } catch (Exception e){ e.printStackTrace(); } finally { if(httpURLConnection != null){ httpURLConnection.disconnect(); } } return data; } } 服务器代码：
app.post('/', function (req, res) { var a = req.body; console.log(a); res.send(a); })
和JSON看起来像这样：
{ '{"name":"ffffc","email":"asdxx","password":"ffv","tel":"111"}': '' }
但应该看起来像这样：
{"name":"ffffc","email":"asdxx","password":"ffv","tel":"111"}
您的Java代码需要将它的Content-Type设置为application/json ，如下所示：
httpURLConnection.setRequestProperty("Content-Type", "application/json");
