How to collect tweets/retweets using GNIP API in php - php

Question

Since twitter has switched to streaming his API, we have to collect the data by ourselves.
How we can do it using GNIP API in php?

Answer 1

Answering this, I’ve just wanted to ensure that I’ve done everything right and maybe to improve my TwitterGnipClient class with your help.
But if there are no answers, let it be FAQ style question.
Main methods see below:
/**
* Add rules to PowerTrack stream’s ruleset.
* #example ['id' => 'url', ...]
* #param array $data
*/
public function addRules(array $data)
{
$rules = [];
foreach ($data as $id => $url) {
$rules[] = $this->buildRuleForUrl($url, $id);
}
$this->httpClient->post($this->getRulesUrl(), [
'auth' => [$this->getUser(), $this->getPassword()],
'json' => ['rules' => $rules]
]);
}
/**
* Retrieves all existing rules for a stream.
* #return \Generator
*/
public function getRules()
{
$response = $this->httpClient->get($this->getRulesUrl(), [
'auth' => [$this->getUser(), $this->getPassword()]
]);
$batchStr = '';
$body = $response->getBody();
while (!$body->eof()) {
$batchStr .= $body->read(1024);
}
$batchArray = explode(PHP_EOL, $batchStr);
unset($batchStr);
foreach ($batchArray as $itemJson) {
yield $this->unpackJson($itemJson);
}
}
/**
* Removes the specified rules from the stream.
* #param $data
*/
public function deleteRules($data)
{
$rules = [];
foreach ($data as $id => $url) {
$rules[] = $this->buildRuleForUrl($url, $id);
}
$this->httpClient->delete($this->getRulesUrl(), [
'auth' => [$this->getUser(), $this->getPassword()],
'json' => ['rules' => array_values($rules)]
]);
}
/**
* Open stream through which the social data will be delivered.
* #return \Generator
*/
public function listenStream()
{
$response = $this->httpClient->get($this->getStreamUrl(), [
'auth' => [$this->getUser(), $this->getPassword()],
'stream' => true
]);
$batchStr = '';
$body = $response->getBody();
while (!$body->eof()) {
$batchStr .= $body->read(1024);
$batchArray = explode(PHP_EOL, $batchStr);
// leave the last piece of response as it can be incomplete
$batchStr = array_pop($batchArray);
foreach ($batchArray as $itemJson) {
yield $this->processBroadcastItem($this->unpackJson($itemJson));
}
}
$body->close();
}
/**
* Process broadcast item data
* #param $data
* #return array
*/
protected function processBroadcastItem($data)
{
if (is_array($data)) {
$url = str_replace('url_contains:', '', $data['gnip']['matching_rules'][0]['value']);
switch ($data['verb']) {
// Occurs when a user posts a new Tweet.
case 'post':
return $this->getMappedResponse($url, 'tweet', 1);
break;
// Occurs when a user Retweets another user's Tweet
case 'share':
return $this->getMappedResponse($url, 'retweet', $data['retweetCount']);
break;
}
}
return [];
}
