如何将多个json值发送到服务器。
public class UserVO {
private String userId;
private String firstName;
private String lastName;
private String mobileNumber;
private String stdCode;
private String landlineNumber;
private String countryCode;
private String stateCode;
private String zipcode;
private String status;
private LoginVO loginVO;
private AddressVO addressVO;
private proofVO proofVO VO;
}
next_Edit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new CreateUser().execute();
}
});
class CreateUser extends AsyncTask<String, String, String> {
int success=0;
JSONObject json;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(ConsentActivity.this);
pDialog.setMessage("Registering New User..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args) {
SharedPreferences pref = getSharedPreferences("UserMgmt", Context.MODE_PRIVATE);
String Firstname = pref.getString("FName", "");
String Lastname = pref.getString("LName", "");

boolean Consent_chk_state = pref.getBoolean("ChkBoxConsent", true);
String status_con_chk=String.valueOf(Tc_chk_state);
String status_con=status_con_chk.substring(0,1);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("userId", Userid));
params.add(new BasicNameValuePair("firstName", Firstname));
params.add(new BasicNameValuePair("lastName", Lastname));
params.add(new BasicNameValuePair("identityType", Idproof_typ));

params.add(new BasicNameValuePair("zipcode", Pincod));
params.add(new BasicNameValuePair("status", status_tc));
params.add(new BasicNameValuePair("password", Password));
params.add(new BasicNameValuePair("address", Address));
/*json = jsonParser.makeHttpRequest(url_new_user,
"POST",params);*/
// Log.d("Create Response", json.toString());
JSONArray jsonArray = new JSONArray();
final JSONObject json = new JSONObject();
final JSONObject login = new JSONObject();
final JSONObject address = new JSONObject();
final JSONObject identity = new JSONObject();
HttpResponse response;
HttpClient client = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost post = new HttpPost("http://191.121.1.145:8080/medicine/services/users/createUser");
post.setHeader("Content-type", "application/json");
try {
Log.e("userId",Userid);

jsonArray.put(json);
try{

jsonArray.put(login);
}catch(Exception exception){
exception.printStackTrace();
}
try{
address.put("address",Address);
jsonArray.put(address);
}catch(Exception exception){
exception.printStackTrace();
}
try{
identity.put("identityType",Idproof_typ);
identity.put("identityNumber",Idproof_number);
jsonArray.put(identity);
}catch(Exception exception){
exception.printStackTrace();
}
StringEntity se = new StringEntity( jsonArray.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(se);
response = client.execute(post);
HttpEntity entity = response.getEntity();
if (response.getStatusLine().getStatusCode() == 201){
Log.e("Responce","OK");
}
}
catch(Exception e) {
e.printStackTrace();
//Toast.makeText(getApplicationContext(), "establishment with server failed", Toast.LENGTH_LONG).show();
// createDialog("Error", "Cannot Estabilish Connection");
}
/*try {
success = json.getInt(TAG_SUCCESS);
} catch (JSONException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}*/
return null;
}
protected void onProgressUpdate(Integer... progress) {
}
protected void onPostExecute(String file_url) {
// dismiss the dialog once done
pDialog.dismiss();
/* try {
int success = json.getInt(TAG_SUCCESS);*/
if (success == 1) {
// successfully created a user
Intent i = new Intent(getApplicationContext(), LoginActivity.class);
startActivity(i);
// closing this screen
finish();
} /*else {
// failed to create user
// Log.d("failed to create user", json.toString());
}*/
/*} catch (JSONException e) {
e.printStackTrace();
}*/
}
}
这里upto状态是直接值，在userVO中另外三个VO就像loginVO，AddressVO，proofVO。
在这些VO课程中有5个值。
现在如何使用POST方法将这些详细信息发送到服务器。我完全糊涂了。
请你明确解决这个问题吗？

要将对象转换为JSON，您可以使用GSON library。
Gson是一个Java库，可用于将Java对象转换为 他们的JSON表示。它也可以用于转换JSON 字符串到等效的Java对象。

您可以使用HTTP post方法发送数据。
public void postData(){
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yourdomain.com/post.php");
try {
// Add your data
List nameValuePairs = new ArrayList(1);
// Your user variable which are directly send from here
nameValuePairs.add(new BasicNameValuePair("data1", "dataValue"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
InputStream is = response.getEntity().getContent();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(20);
int current = 0;
while((current = bis.read()) != -1){
baf.append((byte)current);
}
/* Convert the Bytes read to a String. */
text = new String(baf.toByteArray());
txtvw.setText(text);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
另外，我建议您使用非常简单的ION网络库。
您将找到所需的所有信息。

您必须将其作为HTTP发送。 HTTP消息以文本形式发送。因此，您需要创建JSON对象的字符串表示形式。 像
这样的东西{
UserVO: {
userId: "",
firstName: ""
}
}
答案 3 :(得分：0)
您是否尝试使用名称值对???如果没有尝试使用我的以下代码
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("url");
List<NameValuePair> value = new ArrayList<NameValuePair>();
value.add(new BasicNameValuePair("userid", userId)); //the userid which is inside the "" is server variable
//Form as like above for all variable then use below line of code to get response
post.setEntity(new UrlEncodedFormEntity(name));
HttpResponse response = client.execute(post);
BufferedReader rd = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
String line = "";
StringBuilder sb = new StringBuilder();
while ((line = rd.readLine()) != null) {
sb.append(line + "\n");
}
String result = sb.toString();
