I am using Volley for my HTTP requests and I have an HTTP put URL which looks like below.
http://mycompany.com/favorite/{roomNumber}/count. I am using a JSON object request. How do I make the API work with the extra "/count" in the API? I am passing the parameter room number in the JSON object.
JSON Object request works fine with this type of URL "http://mycompany.com/favorite/{roomNumber}"
JSON Object request
JsonObjectRequest request = new JsonObjectRequest(METHOD_TYPE_PUT, url, jsonObjectParams, responseListener, errorListener)
Can somebody help me with passing the JSON object parameter in the middle of the URL
Thanks.
You can call the API dynamically like this,
private void getTheApiData(int roomNumber){
JsonObjectRequest request = new JsonObjectRequest(METHOD_TYPE_PUT,
"mycompany.com/favorite" + roomNumber + "/count",
jsonObjectParams, responseListener, errorListener)
}
and call the above API dynamically by the method when you get the new data every time like this.
getTheAPiData(20) //if room number is 20
let me know if you have any issue #Shravani
Im using Laravel v7 and i have a question about pagination.
So far im using 2 routes, 1rst to return a view with all rows from database, and 2nd receives an input and returns that view with the rows filtered by that input value.
But im using pagination, and on the 2nd route, when i try to go to 2nd page it gives me an error:
Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException
The GET method is not supported for this route. Supported methods: POST.
I've tried to change my form method to GET but i need that the token doesn't appear on the page URL and beside that, when i go to 2nd page, it returns all the rows again.
Thats my code so far:
Routes:
Route::get('concessions', 'ConcessionController#index')->name('concessions.index');
Route::post('concessions/search', 'ConcessionController#search')->name('concessions.search');
Controller
class ConcessionController extends Controller
{
public function index()
{
$concessions = DB::table('concessions')->paginate(12);
return view('admin.concessions.index', compact('concessions'));
}
public function search(Request $request)
{
$name = $request->name;
$concessions = Concession::where('name', 'like', '%' . $name . '%')->paginate(12);
return view('admin.concessions.index', compact('concessions', 'name'));
}
}
Any way to do that?
Laravel pagination only works with get parameters.
You should use GET method for your search page. POST requests aren't meant for the purpose of displaying data. Why? There are many reasons, but to be short I will give you three examples :
1. When you access the first page, you get the data by GET request,
not POST request. So if you want to use POST request, you
need to access the page as POST request by sending data with
POST method.
2. With GET parameters, let's say you are on 5th page - you can
copy the link and paste it to friend and he will be able to view
the same content as you. With POST this is impossible.
3. You can not use back button with POST requests, if you manage to
get pagination to work.
POST requests are useful when you need to submit data to the server, in order to create new record, for example.
So I suggest you to change your route type to GET.
From my perspective, if you change your route code similar to below code, it will work properly with both methods of GET and POST.
Route::any('concessions/search', 'ConcessionController#search')->name('concessions.search');
I want to pass an array in postman in which there is a image field.
But I am not getting it in to controller.
How Can I do it ?
I am passing the value like as below image.
In Header :
In my controller :
if($request->get('documentObject'))
{
foreach ($request->get('documentObject') as $documentDetails) {
if(Input::file($documentDetails['documentimage']))
{ // i am not getting it
}
How can I get it?
Make sure your form markup contains enctype multipart/form-data. Otherwise, file will be null.
For troubleshooting, you could also dump out the contends of the request to see what the browser is sending: dd($request->all()).
I need to return a json object to my view. I see my subscriptions in tinker:
\App\User::find(1)->with('subscriptions')->where('id', 1)->get();
In my view, I get my user data but the subscriptions array is emply (length: 0)
Issue one, why I could not just \App\User::find(1)->with('subscriptions')->get() This returns all users in my database.
How can I return, as json, the current user with subscriptions? The long way is to make two api calls.
Im using Cashier for the subscriptions
Try to check the query log by running
\DB::enableQueryLog();
$data = \App\User::with('subscriptions')->find(1);
$query = \DB::getQueryLog();
dd($query);
It will show you what queries running behind the seens.
then for the json format try to decode into json and then pass to view.
$json_format = json_encode($data);
return view('user.index')->withJsonFormat($json_format);
Don't know why you want to pass the data with json format. but if you want to pass this into javascript, jquery or angular please create saperate API and call with AJAX.
The correct query is:
App\User::with('subscriptions')->find(1)
It will return User object with this user's subscriptions.
#JsonView
how can use like parameter from request:
#JsonView(header="range")
when response value,read request header range to exclude/include some field
JsonView provides "static" view mapping. so for your dynamic behaviour you can do like this:
// actual request handling is happened here
private ResponseEntity<SomeObject> processRequest();
// request handling with view limit in result
#JsonView(YourDefinedView.class)
#RequestMapping(value = "/request", headers={"range=include"})
public ResponseEntity<SomeObject> processWithView() {
return processRequest();
}
// request handling without view (no headers specified)
#RequestMapping(value = "/request")
public ResponseEntity<SomeObject> processWithoutView() {
return processRequest();
}
this will map your client to same request url, but depending on header it will provide view or not. Than you can create a set of methods, that will be using different #JsonView depending on headers information.
But with this you will limit only the data transfered to client, and the whole data load will happen on server. For example with database and JPA, if you would like not to fetch from database all that data you will end with javax.persistence.NamedEntityGraphs, which will change the general logic of your application - and will at the end of the day produce 2 different methods.
And if you would like to expose custom header with list of fields, to be serialized - custom DTO object, or Map<String, Object> (ugly-ugly-ugly) or custom HandlerMethodReturnValueHandler comes to your help.
