Set header HTTP code in Flightphp - php

im developing an API with FlightPHP microframework and I can't set an HTTP response code for my routes.
I can set this and works perfectly:
header('HTTP/1.0 500 Error');
But I want use the native function http_response_code() from PHP. This one don't do anything.
I want to use this because that I don't have to manually type the error message.

To return a HTTP response code using Flight, you can do it like this :
Flight::route('GET /', function(){
Flight::json($data, $code = 500);
});
Where $data is the variable that leads to the array you want to send in json.
If $code is not set, then the default returned HTTP response code is "200".
https://github.com/mikecao/flight/blob/e25f023d4377a2b99b4be8bf7977f3fc0f8089c8/flight/Engine.php#L500

from flight php
Flight::json($data, [$code], [$encode], [$charset], [$option]) // Sends a JSON response.
Flight::jsonp($data, [$param], [$code], [$encode], [$charset], [$option]) // Sends a JSONP response.

I had a similar problem, to send my own headers, I do so:
$code = 404;
Flight->before('stop', function(&$params) use ($code) {
$params[0] = $code;
});

How to get HTTP status answer from GuzzleHttp response by php Laravel?

I develop at php Laravel.
I receiving GuzzleHttp response from Mailgun as Object and can't to get from it the status.
the Object is:
O:8:"stdClass":2:{s:18:"http_response_body";O:8:"stdClass":2:{s:6:"member";O:8:"stdClass":4:{s:7:"address";s:24:"test_of_json-4#zapara.fr";s:4:"name";s:10:"not filled";s:10:"subscribed";b:1;s:4:"vars";O:8:"stdClass":0:{}}s:7:"message";s:36:"Mailing list member has been created";}s:18:"http_response_code";i:200;}
I need just last data pair:
"http_response_code";i:200;
to get it into variable, like:
$http_response_code = 200;
or even just its value.
To get string as I cited above I use
$result_ser = serialize($result);
but yet can't to extract value of variable.
Also I tried this:
$this->resultString .= \GuzzleHttp\json_decode($result_ser, true);
and get error.
Please, explain me , How to get/extract value I needed?
To take the response status code you can use the function getStatusCode :
$response = $client->request();
$statusCode = $response->getStatusCode();
while to take the body of response you can use :
$contents = $response->getBody()->getContents();
let's consider your request is something like
$response = $client->get("https://example.com");
if ( $object_res->getStatusCode() == 200 ) { // here you are checking your http status code
}
$object_res->getStatusCode() is the method to get http status code.
refer docs, there is simple example in this page.
I found that 'mailgun/mailgun' package uses its own HTTP client which also uses 'RestClient' and these classes are return stdObject.
In that Object there is property 'http_response_code' containing HTTP response code like 200, 400, 401 etc.
This property accessible by standard way $object->property and it's a solution of my query in this case.
For anybody who will read this question and answers I should to explain one thing that I not cleared in question.
I made request to the Mailgun API for subscribing member to mailing list. The API returns stdObject, not JSON or XML data.
But also there is one more strange thing - stdObject returned when request is successful only. If request fails you'll get just Exception thrown with message and without code. This forced me, if fail, to parse message body instead of get and resolve error code.
$responseObj->getStatusCode();

retrofit2 sending a PUT request method is wrong for PHP

I am trying to send a PUT request method from my Android app to my PHP endpoint but in my endpoint the PUT request is not recognized as a PUT request so I return Request method is wrong! message from my endpoint.
Android interface and request execution
Interface for activation
#PUT("device/activate.php")
Call<DeviceRegistry> registryDevice();
Executing the request
DeviceRegistryAPI registryAPI =
RetrofitController.getRetrofit().create(DeviceRegistryAPI.class);
Call<DeviceRegistry> registryCallback = registryAPI.registryDevice();
response = registryCallback.execute();
With this I am expecting a response but I am getting my endpoint error message.
My PHP endpoint
if($_SERVER['REQUEST_METHOD'] == "PUT"){
//doing something with the data
} else {
$data = array("result" => 0, "message" => "Request method is wrong!");
}
I don't know why the $_SERVER['REQUEST_METHOD'] == "PUT" is false but I wonder if I am missing something on Retrofit 2.
More Info.
I am using Retrofit2.
Update 1: Sending json into the body
I am trying to send a json using the body.
It is my json:
{
"number": 1,
"infoList": [
{
"id": 1,
"info": "something"
},
{
"id": 2,
"info": "something"
}
]
}
There are my classes:
class DataInfo{
public int number;
public List<Info> infoList;
public DataInfo(int number, List<Info> list){
this.number = number;
this.infoList = list;
}
}
class Info{
public int id;
public String info;
}
I changed the PUT interface to this:
#PUT("device/activate.php")
Call<DeviceRegistry> registryDevice(#Body DataInfo info);
But I am getting the same problem.
Update 2: Do I need Header
I have this header in my REstfull client:
Accept: application/json
Content-Type: application/x-www-form-urlencoded
Do I need to put this on my request configuration? How do I do that if I need it?
Update 3: checking the request type of my sending post.
Now I am checking the type of the request. Because I am having the same problem with the PUT/POST requests. So If can solved the problem with the put maybe all the problems will be solved.
When I execute the request and asking and inspect the request it is sending the the type (PUT/POST) but in the server php only detect or GET?? (the below example is using POST and the behavior is the same)
Call<UpdateResponse> requestCall = client.updateMedia(downloadItemList);
Log.i("CCC", requestCall .request().toString());
And the output is a POST:
Request{method=POST, url=http://myserver/api/v1/media/updateMedia.php, tag=null}
so I am sending a POST (no matter if I send a PUT) request to the sever but why in the server I am receiving a GET. I am locked!!! I don't know where is the problem.
Update 4: godaddy hosting.
I have my php server hosting on godaddy. Is there any problem with that? I create a local host and everything works pretty good but the same code is not working on godaddy. I did some research but I didn't find any good answer to this problem so Is possible that godaddy hosting is the problem?
PHP doesn't recognize anything other than GET and POST. the server should throw at you some kind of error like empty request.
To access PUT and other requests use
$putfp = fopen('php://input', 'r'); //will be a JSON string (provided everything got sent)
$putdata = '';
while($data = fread($putfp, filesize('php://input')))
$putdata .= $data;
fclose($putfp);
//php-like variable, if you want
$_PUT = json_decode($putdata);
did not tested, but should work.
I guess the problem is that you don't pass any data along with PUT request, that's why PHP recognizes the request as a GET. So I think you just need to try to pass some data using #FormUrlEncoded, #Multipart or probably #Body annotations
To add header in your retrofit2 you should create an interceptor:
Interceptor interceptor = new Interceptor() {
#Override
public okhttp3.Response intercept(Interceptor.Chain chain) throws IOException
{
okhttp3.Request.Builder ongoing = chain.request().newBuilder();
ongoing.addHeader("Content-Type", "application/x-www-form-urlencoded");
ongoing.addHeader("Accept", "application/json");
return chain.proceed(ongoing.build());
}
};
and add it to your client builder:
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.interceptors().add(interceptor);
PHP recognises 'PUT' calls. Extracted from PHP.net:
'REQUEST_METHOD' Which request method was used to access the page;
i.e. 'GET', 'HEAD', 'POST', 'PUT'.
You don't need to send any header if your server isn't expecting any
header.
Prior to use Retrofit or any other networking library, you should check the endpoint using a request http builder, like Postman or Advanced Rest Client. To debug the request/response when running your app or unit tests use a proxy like Charles, it will help you a lot to watch how your request/response really looks.

Use PHP to get JSON data from REST API

I'm new in REST API. I'm building up a test environment and trying to make a handshake between Rest API and Client side PHP.
My JSON data is at
http://localhost:50417/api/device
the data is like:
[
{"Truck_ID":1,"Company":"Food Mall","Distance":2000},
{"Truck_ID":2,"Company":"Food Mall","Distance":4000},
{"Truck_ID":3,"Company":"Food Mall","Distance":3050}
]
I'm trying to act like a client, use PHP to get the data, and put the data in an array. What I tried on client side which is http://localhost:8080 is
<?php
$url = "http://localhost:50417/api/device";
$response = file_get_contents($url);
echo $response;
?>
I also tried js like
<script type="text/javascript">
$(document).ready(function(){
$.getJSON("http://localhost:50417/api/device",
function(data){
alert (data) // this will show your actual json array
});
});
</script>
But no matter what I tried, I always get a "No 'Access-Control-Allow-Origin' header is present on the requested resource." What could be the problem? How clients generally get the data from server using REST API? Thank you.
allow cross origin requests
Enable it in the .htaccess by putting the below line
Header set Access-Control-Allow-Origin "*"
or try from php
<?php
header('Access-Control-Allow-Origin: *');
$url = "http://localhost:50417/api/device";
$response = file_get_contents($url);
echo $response;
?>

Calling ASP.NET Web Api method with PHP

I have the following web method in my web api controller
public HttpResponseMessage PostMakeBooking(FacilityBookingRequest bookingRequest)
{
var returnStatus = HttpStatusCode.OK;
var json = new JavaScriptSerializer().Serialize(bookingRequest);
var response = Request.CreateResponse<CardholderResponse>(returnStatus, cardholderResponse);
return response;
}
When I make this call from my .NET app, my json string appears correctly when I seralize it
{"correlationId":null,"RequestId":"7ec5092a-342a-4e32-9311-10e7df3e3683","BookingId":"BK-123102","CardholderId":"123456","BookingFrom":"\/Date(1370512706448)\/","BookingUntil":"\/Date(1370523506449)\/","DeviceId":"ACU-01-R2","Action":"Add","LoginId":"tester","Password":"tester"}
However, when I made to call from my php script
public function web_request(){
$guid =self::getGUID();
$replace = array("{","}");
$guid = str_replace($replace, "", $guid);
$client = new Zend_Rest_Client("http://203.92.72.221");
$request= new myZendCommon_FacilityBookingRequest();
$request->RequestId =$guid;
$request->BookingFrom ="27/03/2013 05:30";
$request->BookingUntil ="27/03/2013 06:30";
$request->CardholderId ="E0185963";
$request->DeviceId ="ACU-B2-01-R1";
$request->BookingId ="111";
$request->Action ="Add";
$request->LoginId ="tester";
$request->correlationId ="(null)";
$request->Password ="tester";
$request = json_encode($request);
$response = $client->restPost("/ibsswebapi/api/facilitybooking",$request);
print_r($response);
exit();
The call goes to my web method, but when I serialize it using JavaScriptSerializer().Serialize(bookingRequest)
{"correlationId":null,"RequestId":null,"BookingId":null,"CardholderId":null,"BookingFrom":"\/Date(-62135596800000)\/","BookingUntil":"\/Date(-62135596800000)\/","DeviceId":null,"Action":null,"LoginId":null,"Password":null}
All the values are null.
Is something wrong with the script?
I believe Kiran is right. Not sure why some one has felt his answer is not useful. Anyways, my understanding is that you are creating a JSON string and doing a form post of the same. I guess in this case the content type is sent as application/www-form-urlencoded but request body is a JSON string. You can use Fiddler to see how the request is being sent by the PHP script. I don't have the PHP knowledge to tell you how you can post JSON but my guess is that if you just remove the JSON encoding line $request = json_encode($request);, it should be okay.
From ASP.NET Web API point of view, if the request has Content-Type: application/json header and the body has the right JSON or if the request has Content-Type:application/www-form-urlencoded header and the body has the form url encoded content like RequestId=7ec5092a-342a-4e32-9311-10e7df3e3683&BookingId=BK-123102 and so on, web API will absolutely have no problem in binding. Currently, the request is not being sent in the right format for web API to bind.
Are you sending the header Content-Type:application/json in your request?
Also add the following piece of code to catch any model state validation errors:
.
if (!ModelState.IsValid)
{
throw new HttpResponseException(
Request.CreateErrorResponse(HttpStatusCode.BadRequest, this.ModelState));
}

RESTful API Error Handling

I have a simple function that makes a cURL request to my RESTful API, and it returns data as it should when a successful request is made. My problem is, when a user perhaps gives the API wrong data or the API can't do what is requested, I don't know how to return error responses (e.g. 404s, 500s).
How would I go about doing this?
At the moment I have the following. In my API client
class Awesome_Api {
static function request($url, $data, $method)
{
// cURL stuffs here...
if (successful)
{
return (success response)
}
else
{
return (error response)
}
}
}
and
$response = Awesome_Api::request($url, $data, $method);
Now how do I return an error response code from the API, and handle it in the client end?
Use the header function to return error codes, like this:
header('HTTP/1.1 500 Internal Server Error');
or
header('HTTP/1.1 404 Not found');
It is very important that you make sure nothing has been written to the output before calling this function, otherwise it will not work as you expect.
In your client API, you can use the curl_error() and curl_errno() functions to retrieve information about the error number and message returned from the server.
