Web API server controller doesn't get parametrs - android

I send JSON data from android app. In server side I have issue - Web API server controller doesn't get parametrs. From client side I send json data like this:
{ "TypeID ": "1",
"FullName": "Alex",
"Title": "AlexTitle",
"RegionID": "1",
"CityID ": "1",
"Phone1": "+7(705)105-78-70"
}
Any help appreciated, please if you have some information, idea let me know, thank you!
This is controller
[System.Web.Http.HttpPost]
public HttpResponseMessage PostRequisition([FromBody]string requisition)
{
Requisition postReq = new Requisition();
if (!String.IsNullOrEmpty(requisition))
{
dynamic arr = JValue.Parse(requisition);
//PostReq model = JsonConvert.DeserializeObject<PostReq>(requisition);
postReq.FullName = arr.FullName;
postReq.CityID = Convert.ToInt32(arr.CityID);
postReq.RegionID = Convert.ToInt32(arr.RegionID);
postReq.TypeID = Convert.ToInt32(arr.TypeID);
postReq.UserID = 8;
postReq.Title = arr.Title;
postReq.Date = Convert.ToDateTime(arr.Date, CultureInfo.CurrentCulture);
postReq.Decription = arr.Description;
postReq.Phone1 = arr.Phone1;
postReq.Activate = false;
postReq.ClickCount = 0;
try
{
db.Requisition.Add(postReq);
db.SaveChanges();
Message msg = new Message();
msg.Date = DateTime.Now;
msg.Type = "POST";
msg.Text = "OK";
db.Message.Add(msg);
db.SaveChanges();
return Request.CreateResponse(HttpStatusCode.OK, postReq);
}
catch (Exception ex)
{
Message msg = new Message();
msg.Date = DateTime.Now;
msg.Type = "POST";
msg.Text = "ERROR";
db.Message.Add(msg);
db.SaveChanges();
return Request.CreateResponse(HttpStatusCode.OK, ex.Message);
}
}
else
{
Message msg = new Message();
msg.Date = DateTime.Now;
msg.Type = "POST";
msg.Text = "null";
db.Message.Add(msg);
db.SaveChanges();
return Request.CreateResponse(HttpStatusCode.OK, "null");
}
}

Your problem is simple. You are sending a JSON object but are expecting a string in your POST action. Simple way to fix this is creating a class that maps to your JSON object:
public class RequisitionViewModel
{
public int TypeID {get; set;}
public string FullName {get; set;}
public string Title {get; set;}
public int RegionID {get; set;}
public int CityID {get; set;}
public string Phone1 {get; set;}
}
Then, change your action signature to:
[FromBody]RequisitionViewModel requisition)
You also don't need all the converting in your code:
postReq.FullName = requisition.FullName;
postReq.CityID = requisition.CityID;
//other fields...

How to get list of my users in AppLozic

is it possible to get all of my users without adding them to through contacts. My problem is that I store users in Firebase and they can have invisible profile. I need to get only users with visible profiles. How can I achieve this?
Thanks
You can use the below method code for getting all the user users .You need to pass the users of set type then you will get the response in if(!TextUtils.isEmpty(response)){
public String postUserDetailsByUserIds(Set<String> userIds) {
try {
HttpRequestUtils httpRequestUtils = new HttpRequestUtils(this);
final String userDetailsUrl = "https://apps.applozic.com/rest/ws/user/detail";
if (userIds !=null && userIds.size()>0 ) {
List<String> userDetailsList = new ArrayList<>();
String response = "";
int count = 0;
for (String userId : userIds) {
count++;
userDetailsList.add(userId);
if( count% 60==0){
UserDetailListFeed userDetailListFeed = new UserDetailListFeed();
userDetailListFeed.setContactSync(true);
userDetailListFeed.setUserIdList(userDetailsList);
String jsonFromObject = GsonUtils.getJsonFromObject(userDetailListFeed, userDetailListFeed.getClass());
Log.i(TAG,"Sending json:" + jsonFromObject);
response = httpRequestUtils.postData(userDetailsUrl + "?contactSync=true", "application/json", "application/json", jsonFromObject);
userDetailsList = new ArrayList<String>();
if(!TextUtils.isEmpty(response)){
List<UserDetail> userDetails = (List<UserDetail>) GsonUtils.getObjectFromJson(response, new TypeToken<List<UserDetail>>() {}.getType());
for (UserDetail userDetail : userDetails) {
//Here you will get the user details
Log.i("UserDeatil","userId:"+userDetail.getUserId()) ;
Log.i("UserDeatil","display name:"+userDetail.getDisplayName()) ;
Log.i("UserDeatil","image link:"+userDetail.getImageLink()) ;
Log.i("UserDeatil","phone number:"+userDetail.getPhoneNumber()) ;
}
}
}
}
if(!userDetailsList.isEmpty()&& userDetailsList.size()>0) {
UserDetailListFeed userDetailListFeed = new UserDetailListFeed();
userDetailListFeed.setContactSync(true);
userDetailListFeed.setUserIdList(userDetailsList);
String jsonFromObject = GsonUtils.getJsonFromObject(userDetailListFeed, userDetailListFeed.getClass());
response = httpRequestUtils.postData(userDetailsUrl + "?contactSync=true", "application/json", "application/json", jsonFromObject);
Log.i(TAG, "User details response is :" + response);
if (TextUtils.isEmpty(response) || response.contains("<html>")) {
return null;
}
if (!TextUtils.isEmpty(response)) {
List<UserDetail> userDetails = (List<UserDetail>) GsonUtils.getObjectFromJson(response, new TypeToken<List<UserDetail>>() {}.getType());

How to implement instant messaging Application in android

I am working on an instant messaging android application . I have successfully implemented the chat between my application and web application .I have used compile 'io.socket:socket.io-client:0.6.2' library to implement this.

Get sender mail in gmail-api

I am trying to figure it out went through gmail-api developer guide.The message part in gmail-api does not contain any detail about sender any help is appreciated thanks.
Ok I finally did it.Get message payload and then get headers from payload loop through the headers with name "from"
format of header is of the form header=[name:"somename" value:"somevalue"]
here is my code hope it helps someone
private List<MessageReader> getDataFromApi() throws IOException {
String user = "me";
List<MessageReader> labels = new ArrayList<MessageReader>();
ListMessagesResponse listResponse = mActivity.mService.users().messages().list(user).setQ(query).execute();
//int i=0;
for (Message label : listResponse.getMessages()) {
Message m = mActivity.mService.users().messages().get(user, label.getId()).execute();
String a ="";
try{
List<MessagePart> parts =m.getPayload().getParts();
List<MessagePartHeader> headers = m.getPayload().getHeaders();
MessageReader mreader = readParts(parts);
mreader.setDate(m.getInternalDate());
for(MessagePartHeader header:headers){
String name = header.getName();
if(name.equals("From")||name.equals("from")){
mreader.setSender(header.getValue());
break;
}
}
labels.add(mreader);
}catch(Exception e){
a+="The following error occurred:\n" +
e.getMessage();
}
}
return labels;//extractData(labels);
}
private MessageReader readParts(List<MessagePart> parts){
MessageReader mreader = new MessageReader();
int cnt =0;
for(MessagePart part:parts){
try{
String mime = part.getMimeType();
if(mime.contentEquals("text/plain")){
String s = new String(Base64.decodeBase64(part.getBody().getData().getBytes()));
mreader.setText(s);
}else if(mime.contentEquals("text/html")){
String s = new String(Base64.decodeBase64(part.getBody().getData().getBytes()));
mreader.setHtml(s);
}else if(mime.contentEquals("multipart/alternative")){
List<MessagePart> subparts =part.getParts();
MessageReader subreader = readParts(subparts);
mreader.setText(subreader.getText());
mreader.setHtml(subreader.getHtml());
}else if(mime.contentEquals("application/octet-stream")){
cnt++;
mreader.setNo_of_files(cnt);
}
}catch(Exception e){
// get file here
}
}
return mreader;
}
public class MessageReader {
private String text;
private String html;
int no_of_files;
private String sender;
private long date;
// file data to be made
public String getSender() {
return sender;

You could first list messages, to get the id of messages.
Request:
GET https://www.googleapis.com/gmail/v1/users/me/messages
Response:
{
"messages": [
{
"id": "1504f80fcf4ceb5f",
"threadId": "1504f80fcf4ceb5f"
}, ...
]
}
Then, you could ask for the sender of these messages in a second request, by getting the actual message.
Request:
format = metadata
metadataHeaders = From
fields = payload/headers
GET https://www.googleapis.com/gmail/v1/users/me/messages/1504f80fcf4ceb5f?format=metadata&metadataHeaders=From&fields=payload%2Fheaders
Response:
{
"payload": {
"headers": [
{
"name": "From",
"value": "YouTube <noreply#youtube.com>"
}
]
}
}
Assuming that you already got message id using ListMessagesResponse,
here is how you can get sender, i.e. From field:
public String getFrom(String userId, String messageId) throws IOException {
Message message = mService.users().messages().get(userId, messageId).execute();
List<MessagePartHeader> headers = message.getPayload().getHeaders();
String from="";
for (MessagePartHeader header:headers){
if(header.getName().equals("From")){
from=header.getValue();
break;
}
}
return from;
}
From documentation we can know that Users.messages will give us the message with following properties
{
"id": string,
"threadId": string,
"labelIds": [
string
],
"snippet": string,
"historyId": unsigned long,
"internalDate": long,
"payload": {
"partId": string,
"mimeType": string,
"filename": string,
"headers": [
{
"name": string,
"value": string
}
],
"body": users.messages.attachments Resource,
"parts": [
(MessagePart)
]
},
"sizeEstimate": integer,
"raw": bytes
}
From the above properties we can use payload.headers[] to know the Sender mail.
The payload.headers[] will contain array of dictionaries of form {"name":string , "value":string}. To get the sender's mail, we have to find the dictionary with name == 'From' and its corresponding value will give us the sender's mail
I am attaching my python code for reference
#Call the Gmail API
#Before calling the API you have to create service using User credentials
results = service.users().messages().list(userId='me',labelIds = ['INBOX']).execute()
msgs = results.get('messages',[])
for msg in msgs:
mg = service.users().messages().get(userId='me', id=msg['id']).execute()
msg_headers = mg['payload']['headers']
for k in range(len(msg_headers)):
if msg_headers[k]['name'] == 'From':
print(msg_headers[k]['value'])
print("\n")

Hebrew letters are empty

I am building an app which needs to support Hebrew letters (שלום). I am sending a message thru GCM (Google Cloud Messaging). Whenever my OnMessage is called the string (Hebrew) that I am receiving is empty.
Is there any easy workaround for this? Thanks in advance!
protected void onMessage(Context context, Intent intent) {
String message = intent.getStringExtra(GCM_COMMAND);
String action = intent.getAction();
if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) {
message = intent.getStringExtra(GCM_COMMAND);
String s = message.toString();
ItemBean ib =parseJson(s,context);
}
private ItemBean parseJson(String text,Context con) {
ItemBean item = null;
if (text != null) {
JSONObject temp;
try {
temp = new JSONObject(text);
String itemMessage = temp.get(GCM_MESSAGE).toString();
//This String is Empty!
String itemDate = temp.get(GCM_DATE).toString();
long currentTime = System.currentTimeMillis();
item = new ItemBean(currentTime,itemMessage,itemDate);
sendNotification(con,itemMessage,itemDate);
}
}
return item;
}
Server code from NetBeans
JSONObject json = new JSONObject();
System.out.println("******גגגגגגשלום*********");
json.put(GCM_MESSAGE, ib.getmMessage());
//This is hebrew no problem!
json.put(GCM_DATE, ib.getmDate());
Message.Builder builder = new Message.Builder();
Message message = builder.build();
MulticastResult result = sender.send(message, listOfRegisteredDevices, 5);
int success = result.getSuccess();
Can you try :
String itemMessage = temp.getString(GCM_MESSAGE);
and also
json.put(GCM_MESSAGE, JSonObject.quote( ib.getmMessage() ) );
