I want to pass an array as parameter like this:
images[] = "Base64String A..."
images[] = "Base64String B..."
images[] = "Base64String C..."
images[] = "Base64String ..."
I'm using Laravel 5.1 on server side.
My controller to handle post data:
public function uploadTempImage(){
if (Input::has('images')) {
$images = Input::get('images');
$barcode_id =Input::get('barcode_id');
$upload_count=0;
foreach($images as $string_image) {
$image = base64_decode($string_image);
$filename = "$barcode_id$upload_count".time().date("d").date("m").date("Y").".jpeg";
$upload_count +=Storage::disk('local')->put("/tempImage/".$filename , $image);
}
return $upload_count;
}else{
return 'no file uploaded';
}
}
i use postman to test my server and its working..
please help me get over this.. thanks
TL;DR using arrays in form data like this is a bit problematic and hardly standardized. Avoid if possible.
Long version
Read this issue on retrofit's github
If the strings won't be too massive, consider using JSON as your transport vehicle, and declare a JSON array to store your base64 strings.

I am building a Cordova app for Android. I have to parse a JSON that consists of posts. Each post has text (title, description, category etc.) and images (an array of images - can be one or more). My aim is to store the JSON data for offline use (save to SQLlite database). Right now the example code below works, but the sequence is not how I expected to be:
request JSON (ok)
Wait for all promises (ok)
Parse JSON (finishes before all the images are downloaded)
Store to database the information but the images still downloading (in background thread - no harm for the UI).
What I would like to have is to store to database, when all the images have been downloaded. I' ve tried many things such as replacing the second for-loop with a recursive function (to handle the async function as stated here) and many other similar approaches but I believe that the problem starts from the 1st for loop which doesn't wait for the checkCache to finish. What do you think? How can I overcome this issue? If you need any further explanation just ask me.
My setup is:
Cordova 4.0.0, Angular 1.3.1 and ImgCache 1.0
My approach is:
1st. Request JSON:
promise1 = $http({method: 'GET', url: baseURL + options1};
promise2 = $http({method: 'GET', url: baseURL + options2};
//...
2nd. Wait for all promises
return $q.all([promise1,promise2,...]).then(function(data){
var promise1size = data[0].data.posts_number;//posts.length;
parseJSON(data[0],promise1size,'category1');
var promise2size = data[1].data.posts_number;//posts.length;
parseJSON(data[1],promise1size,'category2');
//similar for the rest promises
});
3rd. Parse JSON
function parseJSON(respdata,size,category){
console.log("Parsing "+size+" "+category);
for(i=0;i<size;i++){
var item = {};
item ["id"] = respdata.data.object[i].id;
item ["title"] = respdata.data.object[i].title;
item ["description"] = respdata.data.object[i].description;
var jsarray = respdata.data.object[i].categories;
item ["category"] = jsarray[0].title;
item ["catid"] = jsarray[0].id;
//Other JSON keys here similar as above
//Here it starts...
var jsattachement = respdata.data.object[i].attachments;
var atsize = jsattachement.length;
if(atsize>0){
var images=[];
for(j=0;j<atsize;j++){
(function(j){checkCache(jsattachement[j].url)}(j));//here is the problem
multimedia.push({title:item["title"], src:ImgCache.returnCachedURL(jsattachement[j].url), w:400,h:300});
images.push({title:item["title"],src:ImgCache.returnCachedURL(jsattachement[j].url),w:400,h:300});
}
item ["attachement"] = images;
}else
item ["attachement"] = [];
if(category=='category1')
response.category1.push(item);
else if(category=='category2')
response.category2.push(item);
//else if...
//else if...
}
}
};
checkCache function:
function checkCache (imgsrc){
ImgCache.isCached(imgsrc, function(src, success) {
if(!success){
ImgCache.cacheFile(src, function(){});
}
});
};
4th. Store to database
Here I save the parsed information to the database. On step 3 I use the returnCachedURL function for the images (which is not asynchronous) so to have the local path of the image ready even if it might not have been downloaded yet (but eventually will).
I did this:
Similar to you but, use update sql to store the image for every downloaded image. Then, I found that some of my users want to play with me, they disconnect the internet connection in the middle of image downloading! so that I have incomplete record in the sql! Jesus!
then I change to this: I create a temporary global var. e.g. tempvar = {}, then: tempvar.data1 = 'hello', tempvar.preparedatacompleted = true, tempvar.ImagesToBeDownload = 5, tempvar.ImagesDownloaded = 0, tempvar.imagearray = ......
then, everytime image downloaded, add 1 to the number, if that no. = total no., call the function that save all data and images in this tempvar to the sql.
I am sagar, i am trying to implement the Parse Push-Notification in android using REST API (Service), and i am almost got success in implement the Push-Notification in Xamarin-Android using REST API. But i got stuck with one part in sending the Data into REST service. I trying to pass the ParseObject in service, but the in parse table there is a need of Object,(). I have tried to pass the ParseObject as below:
JsonConvert.SerializeObject(ParseUser.CurrentUser)
It convert ParseObject into array and array is not accepted in table and ,i got failed to save it in table. because there i a need of object.
I need solution or suggestion from developer guys. Yours help will be appreciated. I am trying the below code to achieve the result.
public static void RegisterPush(string regristrationId)

maven
I found the solution in , parse xamarin docs, in one query , the way is simple, but i little bit hard to found out.
The issue is with the data passing in json format in REST, to pass any pointer using REST API, use as below.
The solution is as below:
`{
"user":{
"__type":"Pointer",
"className":"_User",
"objectId":"qYvzFzGAzc"
},
"owner":"qYvzFzGAzc",
"deviceType":"android",
"GCMSenderId":"123456789",
"appName":"NiceApp",
"pushType":"gcm",
"deviceToken":"APA91bFeM10jdrCS6fHqGGSkON17UjEJEfvJEmGpRM-d6hq3hQgDxKHbyrqAIxMnEGgbLEZf0E9AllHxiQQQCdEFiNMF1_A8q0n9tGpBE5NKhvS2ZGJ9PZ7585puWqz_1Z1EjSjOvgZ1LQo708DeL2KzA7EFJmdPAA"
}`
It looks like your column user is set up wrong. It should show as a Pointer<_User> not Pointer
If you load this class in your Data Browser, is the "user" key defined as a string, or a Pointer <_User>
This error seems to indicate that this is a string column, which is why the Parse.User object is not being accepted as a valid value. You might have tried setting a string on this key before, which in turn type-locked the "user" key as a string column.
Found it on the examples given on this page - https://www.parse.com/docs/rest
Have you check your REST API connection while passing ParseObject?
Because your error says:
Error:{"code":111,"error":"invalid type for key user, expected *_User, but got array"}
Here "code":111This error code comes when server refuse for connection
I have a Groovy/Grails website that is being used to send data to Android clients via JSON. I have created both the Android client and the Groovy/Grails website; and they can output the same objects in JSON.
I can successfully create the respective objects in Android by mapping the JSON output to Java objects, however I was wondering if it's possible to use the JSON output to create a new domain object in Groovy/Grails? Is there a way of passing the JSON output to a controller action so that object will be created?
Here is an example of the JSON that I'd like to send;
{
"class":"org.icc.callrz.BusinessCard.BusinessCard",
"id":1,
"businessCardDesigns":[],
"emailAddrs":[
{
"class":"org.icc.callrz.BusinessCard.EmailAddress",
"id":1,
"address":"chris#krslynx.com",
"businessCard":{
"_ref":"../..",
"class":"org.icc.callrz.BusinessCard.BusinessCard"
},
"index":0,
"type":{
"enumType":"org.icc.callrz.BusinessCard.EmailAddress$EmailAddressType",
"name":"H"
}
},
{
"class":"org.icc.callrz.BusinessCard.EmailAddress",
"id":2,
"address":"cb#i-cc.cc",
"businessCard":{
"_ref":"../..",
"class":"org.icc.callrz.BusinessCard.BusinessCard"
},
"index":1,
"type":{
"enumType":"org.icc.callrz.BusinessCard.EmailAddress$EmailAddressType",
"name":"W"
}
}
]
}
The "class" matches to the Domain I'd like to save to, the ID is the ID of the Domain, then each item within the businessCardDesigns and emailAddrs needs to be saved using similar methods (in the Domain the businessCardDesigns and emailAddrs are ArrayLists). Many thanks in advance!
SOLUTION:
#RequestMapping(method = RequestMethod.POST, headers = "Accept=application/json")
public ResponseEntity<String> createFromJson(#RequestBody String json) {
Owner.fromJsonToOwner(json).persist();
return new ResponseEntity<String>(HttpStatus.CREATED);
}
Using the built-in Grails JSON converter makes this easier than the other answers, in my opinion:
import grails.converters.JSON
class PersonController {
def save = {
def person = new Person(JSON.parse(params.person))
person.save(flush:true)
}
}
The other benefits are:
There's no need to muck around in any config files
The resulting JSON object can be manipulated, if necessary, before assigning properties
It's far clearer in the code what's happening (we're parsing a JSON object and setting the properties on the Person entity)
I know you already accepted an answer but if I'm reading your question right, there's a built in "Grails" way to do this.
Create an entry for your action in URLMappings.groovy and turn on request parsing. For example, I create RESTful mappings like so:
"/api/bizCard/save"(controller: "businessCard", parseRequest: true) {
action = [POST: "save"]
}
And then in you controller
def save = {
def businessCardInstance = new BusinessCard(params.businessCard)
....
businessCardInstance.save(flush:true)
}
this might work for you

I am currently developing an Android application using Flex 4.5.1 and I am having an issue when trying to pass data that I have stored in a SharedObject array to my Web Service for a Database query. the code below shows how I am storing the data in the SharedObject:
var so:SharedObject = SharedObject.getLocal("app");
public var prefsArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefsArray.source.push(getFrsByIDResult.lastResult.id);
so.data.prefs = [prefsArray];
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
I have tested the SharedObject to see if the information is being entered into it correctly and all seems fine. Now I have used the code below in order to retrieve the data from the SharedObject and try and send it to the PHP web Service to run the DB query.
var so:SharedObject = SharedObject.getLocal("app");
var arrCol:ArrayCollection = new ArrayCollection(so.data.prefs);
var str:String = new String(arrCol.toString());
protected function list_creationCompleteHandler(event:FlexEvent):void
{
getPrefsByprefIdsResult.token = prefsService.getPrefsByPrefIds(so.data.prefs);
}
I have tested the Webservice in Flex and have it configured to recieve an Array of Ints (int[]) and it works when i run a test operation on it with two dummy values. However when I try to use the code above to pass the Web Service the Shared Object data I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert []#97e97e1 to mx.collections.ArrayCollection.

I have replaced certain filenames and locations with *'s to protect the work i am doing, but can someone please help me with this issues as I believe it has to be something simple???
Thanks
ok so let me explain in more detail. This is being designed for an Android app like I said, but image what I am trying to do is to store Bookmarks persistently using the Local Shared Object.
The first chunck of code you see above is designed to create the LSO attribute for the bookmark i want to create and imagine that there can be more than one bookmark set at different times like in a web browser. The only way i could find to do this was to store these items/details in an array which I retrieve and then update before saving back to the LSO and saving.
The second piece of code related to imagine a "Bookmarks Page" with a list of all the content that I have bookmarked. Now what I wanted to happen was thta I would be able to call up the LSO attribute which held the id's of the bookmarks and then load up thier details in a list format.
I have managed to create the LSO and store the bookmark deatils in and allow them to be updated and entries added. Also I have made sure that the PHP code that I have pulls back all the database objects relating to the array of id's and this has been tested using flex. The only thing that I cant seem to do is to pass the id's to the PHP web service file. The code in the Web Service file is below if that helps:
public function getPrefsByPrefIds($PrefIds) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE $this->tablename.id IN(" .implode(",", $PrefIds). ")");
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
$rows = array();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
while (mysqli_stmt_fetch($stmt)) {
$rows[] = $row;
$row = new stdClass();
mysqli_stmt_bind_result($stmt, $row->id, $row->name, $row->desc);
}
mysqli_stmt_free_result($stmt);
mysqli_close($this->connection);
return $rows;
}
Yes I had already tried that but thanks. I have made some more progress on my own as I have been experimenting with the different types of objects that can be stored in SharedObjects. I have managed to get the solution part working with this code:
This code is designed to capture the boomark info and store it in an arrayCollection before transferring it to a bytesArray and saving
var so:SharedObject = SharedObject.getLocal("app");
public var prefArray:ArrayCollection = new ArrayCollection(so.data.prefs);
protected function prefs_btn_click(event:MouseEvent):void
{
prefArray.source.push(getCompaniesByIDResult.lastResult.id);
so.data.prefs = [prefArray];
var bytes:ByteArray = new ByteArray();
bytes.writeObject(prefArray);
so.data.ac = bytes;
var flushStatus:String = so.flush();
if (flushStatus != null) {
switch(flushStatus) {
case SharedObjectFlushStatus.PENDING:
so.addEventListener(NetStatusEvent.NET_STATUS,
onFlushStatus);
break;
case SharedObjectFlushStatus.FLUSHED:
trace("success");
break;
}
}
}
protected function onFlushStatus(event:NetStatusEvent):void
{
trace(event.info.code);
}
This next code is the designed to retrieve that information from the SahredObjects bytesArray and put it back into an Array Collection
var so:SharedObject = SharedObject.getLocal("app");
var ba:ByteArray = so.data.ac as ByteArray;
var ac:ArrayCollection;
protected function list_creationCompleteHandler(event:FlexEvent):void
{
ba.position = 0;
ac = ba.readObject() as ArrayCollection;
getPrefsByPrefIdsResult.token = prefsService.getPrefsByPrefIds(ac);
}
however as I have said this works in a small way only as if I store only one Bookmark (id) for an item and then go to the bookmarks list the details for that bookark are successfully retrieved, however if I save more than one Bookmark(2 or more id's) the page will not load the details, i do not get an error but I believe it is hanging because it is looking for say id's "1,2" instead of "1" and "2" but i dont know why this is or how to resolve this. I appreciate the advice I have been given but am finding it hard there is no one who can help me with this issue and I am having to do various experiemnts with the code. Can someone please help me with this I would really appreciate it :-) Thanks
i'm working on a API, and i want to take the json data that is display in an adress like this : https://api.empireavenue.com/profile/info/?apikey=YOURAPIKEY&username=TICKER&password=PASSWORD
and take this data to display it on my app .
Thanks.
The input to the parseJson method should be whatever you get back from the HTTP request. This also assumes the format is something like:
{"rootKey":{"intVal":1}}
You will have to modify the order in which you query objects depending on the structure.
private static final ROOT_JSON_KEY = "rootKey";
private static final INT_VALUE_NAME = "intVal";
public void parseJson(String webServiceResponse) {
JSONObject json = new JSONObject(webServiceResponse);
JSONObject rootObject = json.getJSONObject(ROOT_KEY);
int intValues = rootObject.getInt(INT_VALUE_NAME);
}
EDIT: Sorry, stupid coding error.
