我想发送文本值到服务器，这是名称，电话，位置，备注，但每次每个值都丢失 第一次名称不会，下次拨打电话和下一个位置。 ..我的JSONObject发送空值到服务器

更新：

Jsoncode：

public static String POST(String url, Persoenter code heren person){ 
    InputStream inputStream = null; 
    String result = ""; 
    try { 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 
     String json = ""; 
     JSONObject jsonObject = new JSONObject(); 
     jsonObject.accumulate("name",person.getName()); 
     jsonObject.accumulate("phone", person.getPhone()); 
     jsonObject.accumulate("remarrks",person.getRemarks()); 
     jsonObject.accumulate("credated_dt", person.getCreatedat()); 
     jsonObject.accumulate("emp_code", person.getCreatedby()); 
     jsonObject.accumulate("location", person.getLocation()); 
     jsonObject.accumulate("add_fld1", "Test"); 
     jsonObject.accumulate("add_fld2", "Test"); 
     jsonObject.accumulate("add_fld3", "Test"); 
     json = jsonObject.toString(); 
     StringEntity se = new StringEntity(json); 
     Log.e("sent",""+json); 
     httpPost.setEntity(se); 
     httpPost.setHeader("Accept", "application/json"); 
     httpPost.setHeader("Content-type", "application/json"); 
     HttpResponse httpResponse = httpclient.execute(httpPost); 
     inputStream = httpResponse.getEntity().getContent(); 
     if(inputStream != null) 
      result = convertInputStreamToString(inputStream); 
     else 
      result = "Did not work!"; 
    } catch (Exception e) { 
     Log.d("InputStream", e.getLocalizedMessage()); 
    } 
    return result; 
} 

Httppost

private class sync extends AsyncTask<String, String, String> { 
    InputStream inputStream = null; 
    OutputStream outputStream = null; 
    protected String doInBackground(String... urls) { 
     person = new Person(); 
     person.setName(eName.getText().toString()); 
     person.setPhone(ePhonenumber.getText().toString()); 
     person.setLocation(eLocation.getText().toString()); 
     person.setRemarks(eRemarks.getText().toString()); 
     person.setCreatedby(eCreatedby.getText().toString()); 
     person.setCreatedat(eCreatedat.getText().toString()); 
     return POST(urls[0],person); 
    } 
@Override 
    protected void onPreExecute() { 
     progress.setTitle("Connecting to server"); 
     progress.setMessage("Sending Data.... Please wait!"); 
     progress.setCanceledOnTouchOutside(false); 
     progress.show(); 
    } 
    @Override 
    protected void onPostExecute(String s) { 
       progress.dismiss(); 
       Intent Homeintent = getIntent(); 
Homeintent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION); 
finish(); 
startActivity(Homeintent); 
    } 

输出 1：{ “名称”： “beta33”， “电话”： “33”， “remarrks”： “33”， “credated_dt”：“2017年12月20日11 ：56：32“，”emp_code“：”[email protected]“，”location“：”33“} 2：{”name“：”beta33“，”phone“：”33“，”remarrks“： “33”，“credated_dt”：“2017-12-20 11:56:43”，“emp_code”：“[email protected]”，“location”：“33”} 3：{“name”：“ “，”电话“：”34“，”remarrks“：”34“，”credated_dt“：”2017-12-20 11:56:52“，”emp_code“：”[email protected]“，”位置“ ：“34”}

在尝试了一两次尝试之后，名字不会出现，我不知道为什么......请别人帮我解决这个问题

回答：

try { 
      URL url = new URL("http://-------"); 
      HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection(); 
      httpURLConnection.setDoOutput(true); 
      httpURLConnection.setRequestMethod("POST"); 
      httpURLConnection.setRequestProperty("Content-Type", "application/json"); 
      httpURLConnection.connect(); 
      DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream()); 
      wr.write(inputJson.getBytes()); //your input json in string format 
      wr.flush(); 
      BufferedReader br = new BufferedReader(new InputStreamReader(
        (httpURLConnection.getInputStream()))); 
      StringBuffer bfr = new StringBuffer(); 
      String output = ""; 
      while ((output = br.readLine()) != null) { 
       bfr.append(output); 
      } 
      String serverPostRes = bfr.toString(); 
      wr.close(); 
      httpURLConnection.disconnect(); 
      bfr.delete(0,bfr.length()); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     return serverPostRes; 
    } 

String inputJson = "{ " 
      + "  \"add_fld1\": \"" + ("Test"+ i) + "\"," 
      + "  \"add_fld2\": \"" + ("Test"+ i+1) + "\"," 
      + "  \"add_fld3\": \"" + ("Test"+ i+2) + "\"," 
      + "  \"credated_dt\": \"" + formattedDate + "\"," 
      + "  \"emp_code\": \"" + eCreatedby.getText().toString() + "\"," 
      + "  \"location\": \"" + eLocation.getText().toString() + "\"," 
      + "  \"name\": \"" + eName.getText().toString() + "\"," 
      + "  \"phone\": \"" + ePhonenumber.getText().toString() + "\"," 
      + "  \"remarrks\": \"" + eRemarks.getText().toString() + "\"," 
      + "}";
