This is my first day to have fun with Symfony and drupal 8, so please excuse me if my question is very obvious.
With drupal 7:
drupal_json_output(array('products' => array_values($products)));
exit;
the json output is clean:
{"products":["item_1","item_2",....]}
With drupal 8:
use Symfony\Component\HttpFoundation\JsonResponse;
// some process
print new JsonResponse(array('products' => array_values($products)));
exit;
It outputs with the headers:
HTTP/1.0 200 OK
Cache-Control: no-cache
Content-Type: application/json
Date: Wed, 18 Jul 2012 07:53:26 GMT
{"products":["item_1","item_2",....]}
How do you get rid of those headers?
I am stuck to read the reference here.
Any hint is very much appreciated.
You can get only the "content" of a response by calling $response->getContent().
In your case you could do
use Symfony\Component\HttpFoundation\JsonResponse;
// some process
$response = new JsonResponse(array('products' => array_values($products)));
print $response->getContent();
exit;
However, be aware that this would be a bad practice because you would lose the response headers in the process, and wouldn't tell for example, what the content-type of you response is (in this case: "application/json") etc ...
I do not know how to do this properly with drupal, any tips is appreciated.

I recently discovered the dataforseo api and tryed to call it via R
library(httr)
username <- 'mygmailadress#gmail.com'
password <- 'mypassword'
dataforseo_api <- POST('https://api.dataforseo.com/v2/op_tasks_post/$data',
authenticate(username,password),
body = list(grant_type = 'client_credentials'),
type = "basic",
verbose()
)
This is the message I have received:
<- HTTP/1.1 401 Unauthorized

Do you know where my issue should come? Can you please help?
It looks like you're improperly configuring config. I don't see a config= in your code. The body is also not encoded correctly.
Also, in the API documentation I don't see anything about grant_type. It looks like an array of tasks should go there, e.g. something like:
{882394209: {'site': 'ranksonic.com', 'crawl_max_pages': 10}}
Response:
{'results_count': 1, 'results_time': '0.0629 sec.', 'results': {'2308949': {'post_id': 2308949, 'post_site': 'ranksonic.com',
'task_id': 882394209, 'status': 'ok'}}, 'status': 'ok'}
OK, so first off we need set_config or config=:
username <- 'Hack-R#stackoverflow.com' # fake email
password <- 'vxnyM9s7FAKESeIO' # fake password
set_config(authenticate(username,password), override = TRUE)

That was one thing. Also to POST data they need you to specify it as json, e.g. encode = "json". From their docs:
All POST data should be sent in the JSON format (UTF-8 encoding). The
keywords are sent by POST method passing tasks array. The data should
be specified in the data field of this POST array. We recommend to
send up to 100 tasks at a time.
Further:
The task setting is done using POST method when array of tasks is sent to
the data field. Each of the array elements has the following
structure:
then it goes on to list 2 required fields and many optional ones.
Note also that you can use reset_config() after as a better practice. If you're going to be running this a lot, sharing it, or using more than 1 computer I would also suggest to put your credentials in environment variables instead of your script for security and ease.
Another final word of advice is that you may want to just leverage their published Python client library and large compilation of examples. Since every new API request is something you'll be pioneering in R without their support, it may pay off to just do the data collection in Python.
This is an interesting API. If you get over to the Open Data Stack Exchange you should consider sharing it with that community.
I'm in desperate need for help on this.
I'm the developer of a site (rockalingua.com) that offers subscriptions to a Learning Management system. We have developed the LMS creating several drupal modules.
It's working quite well so far but we are getting reports from some schools that some students (authenticated users) can't access some content (They get messages stating that they don't have permission to see that content)
This seems to be random, but when this happens the site acts as if they where not logged in. If the log-in again they can access the content usually (they report they sometimes have to restart the browser for that to happen)
The pages that have this problem use a REST API created by us for tracking the students progress.
Searching the logs I realized that some time after a class starts using the system a lot of warning and notice messages are dumped to the messages log reporting unauthenticated users trying to use the API from the same IPs and urls seconds or minutes before, authenticated users where accessing it without any problem.
I've examined all the code involved several times and can't find anything wrong with it, specially when it seems to happen randomly.
I know most schools have a proxy that use a cache. But don't know much about proxies or whether they could be affecting this issue.
If so, what could be do to avoid school proxies caching dynamic pages?
UPDATE:
I include the typical response headers we are sending on the typical affected requests, and some relevant code:

And here you have the code for a typical AJAX request that I have seem to behave as described sometimes:
// ...
if($form_state['data']['is_student']) {
$form['submit'] = [
'#type' => 'submit',
'#value' => t('Go back'),
'#attributes' => [
'class' => [$form_state['data']['activity_type']],
],
'#ajax' => [
'callback' => 'activity_modal_form_submit_callback'
],
];
} else {
}
return $form;
}
/* Ajax callback to update the activity item after closing its modal */
function activity_modal_form_submit_callback($form, &$form_state) {
ctools_include('modal');
ctools_include('ajax');
global $user;
$activities_retriever = new student_task_activities($user->uid, $form_state['data']['task_id']);
$activity = $activities_retriever->lms_student_task_activity($form_state['data']['activity_id']);
$activity_data = array(
//'activity_name' => $activity['title'],
'times' => $activities_retriever->lms_student_task_activity_repetitions_assigned($activity['activity_id']),
'task_activity_entity_id' => $activity['activity_entity'],
'type' => $activity['activity_type'],
'title' => $activity['activity_title'],
'status' => $activity['status'],
'progress' => $activity['progress'],
'is_correctness_supported' => $activity['is_game_supported'],
'percent_right' => $activity['percent_right'],
'is_student' => $form_state['data']['is_student'],
);
$item_updated = render_activity_item(
$form_state['data']['activity_id'],
$activity_data,
$form_state['data']['task_id'],
$form_state['data']['is_student'],
$form_state['data']['due_date'], false);
$commands[] = ctools_modal_command_dismiss();
if($activity_data['type'] == 'video' || $activity['activity_type'] == 'song') {
$commands[] = ajax_command_replace('#activity_' . $form_state['data']['activity_id'], $item_updated);
}
print ajax_render($commands);
drupal_exit();
}
As it calls student_task_activities needs the uid on the constructor to retrieve the activity data and in the described situations it receives a 0, the activity array is empty and when trying to render the activity item a notice is dumped to the log warning about the missing information. There is where it says the uid is 0 and that's how I realized the user id was lost somewhere in the process.
I can't unserstand what I am doing wrong, but when I am sending next request with curl, I am getting error:
echo {"id":1,"question":"aaa"},{"id":2,"question":"bbb?"} | curl -X POST --data-binary #- --dump - http://localhost:8529/_db/otest/_api/document/?collection=sitetestanswers

Any ideas? I tied wrap it's to [...]. Nothing do not help.
With [...] validator mark this as valid
Same with D. Here is my code:
void sendQuestionsToArangoDB(Json questions)
{
string collectionUrl = "http://localhost:8529/_db/otest/_api/document/?collection=sitetestanswers";
auto rq = Request();
rq.verbosity = 2;
string s = `{"id":"1","question":"foo?"},{"id":2}`;
auto rs = rq.post(collectionUrl, s, "application/json");
writeln("SENDED");
}

Same issue with vibed.
ArangoDB do not understand JSON if it's come ass array like [...]. It should be passed as key-value. So if you need pass array it should have key mykey : [].
Here is working code:
import std.stdio;
import requests.http;
void main(string[] args)
{
string collectionUrl = "http://localhost:8529/_db/otest/_api/document?collection=sitetestanswers";
auto rq = Request();
rq.verbosity = 2;
string s = `{"some_data":[{"id":1, "question":"aaa"},{"id":2, "question":"bbb"}]}`;
auto rs = rq.post(collectionUrl, s, "application/json");
writeln("SENDED");
}
otest - DB name
sitetestanswers - collection name (should be created in DB)
echo '[{"id":1,"question":"aaa"},{"id":2,"question":"bbb?"}]'
should do the trick. You need to put ticks around the JSON. The array brackets are necessary otherwise this is not valid JSON.
You are trying to send multiple documents. The data in the original question separates the documents by comma ({"id":1,"question":"aaa"},{"id":2,"question":"bbb?"}) which is invalid JSON. Thus the failed to parse json object answer from ArangoDB.
Putting the documents into angular brackets ([ ... ]) as some of the commentors suggested will make the request payload valid JSON again.
However, you're sending the data to a server endpoint that handles a single document. The API for POST /_api/document/?collection=... currently accepts a single document at a time. It does not work with multiple documents in a single request. It expects a JSON object, and whenever it is sent something different it will respond with an error code.
If you're looking for batch inserts, please try the API POST /_api/import, described in the manual here: https://docs.arangodb.com/HttpBulkImports/ImportingSelfContained.html
This will work with multiple documents in a single request. ArangoDB 3.0 will also allow sending multiple documents to the POST /_api/document?collection=... API, but this version is not yet released. A technical preview will be available soon however.
I am attempting to read the results of the executed header.php/footer.php files as a string of html. Here's the scenario:
There are pages in the site that are developed in a .net environment but they want to share common headers/footers across the entire domain. They wish to have WordPress be the repository for this code and any time there is an update have a PHP cURL call to a .net web service and feed it the new HTML for the header/footers.
I tried calling get_header() but that does not return a string (as I anticipated) so then I tried this test solution in functions.php:
function write_header() {
$header_content = file_get_contents(get_bloginfo('wpurl').'/index.php' );
$fp = fopen('c:\header.txt', 'a+');
fwrite($fp, $header_content);//just testing the output, this will be a cURL call eventually.
fclose($fp);
}
add_action( 'wp_update_nav_menu', 'write_header' );
It seems to be a very heavy handed method of getting the HTML since I'll have to do a lot of string manipulation to parse out the pieces I want. Is there a simpler way of doing this that I'm missing?
If get_header() outputs the header for you, try just wrapping it with an ob_start() and ob_get_contents() to extract the header to a string. You can then discard the output with ob_end_clean(). See the PHP output buffering documentation.
ob_start();
get_header();
$header_as_string = ob_get_contents();
ob_end_clean();
There's a couple ways you can approach this problem (both are a bit of kludge, but what isnt...). The first would be to create a template in your theme's directory that will include only the header and footer calls -- the body of the template can contain a delimiter string like an html comment, e.g. <!-- SPLIT HERE -->.
Request the page through CURL into an output buffer, capturing the resulting response, which you can split into it's component parts using the above delimiter. That will give you your header and footer, complete with the fully rendered tags in the header for css,js, etc. It's not pretty, but it does the job.
The second approach would be an adaptation of the first, which, rather than you doing the splitting, have your .net team take care of it on their end if possible.
UPDATE
Okay, so there's actually a third option, which I completely forgot about, and that's to use one of WP's features: wp_remote_get() http://codex.wordpress.org/Function_API/wp_remote_get
Retrieves a URL using the HTTP GET method, returning results in an array. Results include HTTP headers and content.
This is what you should get back (excerpted from the API docs):
Array
(
[headers] => Array
(
[date] => Thu, 30 Sep 2010 15:16:36 GMT
[server] => Apache
[x-powered-by] => PHP/5.3.3
[x-server] => 10.90.6.243
[expires] => Thu, 30 Sep 2010 03:16:36 GMT
[cache-control] => Array
(
[0] => no-store, no-cache, must-revalidate
[1] => post-check=0, pre-check=0
)
[vary] => Accept-Encoding
[content-length] => 1641
[connection] => close
[content-type] => application/php
)
[body] => <html>This is a website!</html>
[response] => Array
(
[code] => 200
[message] => OK
)
[cookies] => Array
(
)
)
All you'd have to do is pass the URL to a page that's using the template I mentioned above, then handle response from wp_remote_get(); extract the html content form [body] and do your string splitting. Pretty much what you want.

by default I use spool mailing solution for sending newsletter in my web page. But I also need to send email immediately. So I have used this solution
If I send newsletter with Spool everything is fine. But when I use
$mailer = $this->get('instant_mailer');
I receive email with some text prepend at the beginning:
HTTP/1.0 200 OK Cache-Control: no-cache Content-Type: text/html; charset=UTF-8 Date: Fri, 07 Sep 2012 16:19:06 GMT
How to remove this?
I bet that you're trying to send a Response object.
new Response();
it goes to __toString ()
public function __toString()
{
$this->prepare();
return
sprintf('HTTP/%s %s %s', $this->version, $this->statusCode, $this->statusText)."\r\n".
$this->headers."\r\n".
$this->getContent();
}
It is because:
$this->render('template.html.twig');
returns Response to avoid that use:
$response = $this->render('template.html.twig');
$text = $response->getContent();
Regards,
Max
Use
$content = $this->renderView('template.html.twig');
instead of
$content = $this->render('template.html.twig');
render returns a response
Other posible solution to the problem is to use templating service instead of $this->render():
<?php
$body = $this->get('templating')->render('template.html.twig');
