<?php
use Piwik\API\Request;
use Piwik\FrontController;define('PIWIK_INCLUDE_PATH', realpath('../..'));
define('PIWIK_USER_PATH', realpath('../..'));
define('PIWIK_ENABLE_DISPATCH', false);
define('PIWIK_ENABLE_ERROR_HANDLER', false);
define('PIWIK_ENABLE_SESSION_START', false);// if you prefer not to include 'index.php', you must also define here PIWIK_DOCUMENT_ROOT
// and include "libs/upgradephp/upgrade.php" and "core/Loader.php"
require_once PIWIK_INCLUDE_PATH . "/index.php";
require_once PIWIK_INCLUDE_PATH . "/core/API/Request.php";FrontController::getInstance()->init();// This inits the API Request with the specified parameters
$request = new Request('module=API&method=UserSettings.getResolution&idSite=7&date=yesterday&period=week&format=XML&filter_limit=3&token_auth=anonymous
');
// Calls the API and fetch XML data back
$result = $request->process();
echo $result;Here is the output of this script:<?xml version="1.0" encoding="utf-8" ?>
<result><row><label>1920x1080</label><nb_visits>1742</nb_visits><nb_actions>4343</nb_actions><max_actions>89</max_actions><sum_visit_length>349083</sum_visit_length><bounce_count>1135</bounce_count><nb_visits_converted>52</nb_visits_converted><sum_daily_nb_uniq_visitors>1503</sum_daily_nb_uniq_visitors></row><row><label>1366x768</label><nb_visits>1045</nb_visits><nb_actions>2214</nb_actions><max_actions>38</max_actions><sum_visit_length>147636</sum_visit_length><bounce_count>747</bounce_count><nb_visits_converted>26</nb_visits_converted><sum_daily_nb_uniq_visitors>937</sum_daily_nb_uniq_visitors></row><row><label>1680x1050</label><nb_visits>533</nb_visits><nb_actions>1358</nb_actions><max_actions>47</max_actions><sum_visit_length>117723</sum_visit_length><bounce_count>345</bounce_count><nb_visits_converted>11</nb_visits_converted><sum_daily_nb_uniq_visitors>459</sum_daily_nb_uniq_visitors></row>
</result>api调用的方式：
<?php
exit; // REMOVE this line to run the script// this token is used to authenticate your API request.
// You can get the token on the API page inside your Piwik interface
$token_auth = 'anonymous';// we call the REST API and request the 100 first keywords for the last month for the idsite=7
$url = "http://demo.piwik.org/";
$url .= "?module=API&method=Referrers.getKeywords";
$url .= "&idSite=7&period=month&date=yesterday";
$url .= "&format=PHP&filter_limit=20";
$url .= "&token_auth=$token_auth";$fetched = file_get_contents($url);
$content = unserialize($fetched);// case error
if (!$content) {print("Error, content fetched = " . $fetched);
}print("<h1>Keywords for the last month</h1>");
foreach ($content as $row) {$keyword = htmlspecialchars(html_entity_decode(urldecode($row['label']), ENT_QUOTES), ENT_QUOTES);$hits = $row['nb_visits'];print("<b>$keyword</b> ($hits hits)<br>");
}Here is the output of this code:<h1>Keywords for the last month</h1><b>Keyword not defined</b> (16481 hits)<br><b>xxxxxx</b> (80 hits)<br><b>xxx.xxx</b> (9 hits)<br><b>downloads anzeigen</b> (7 hits)<br><b>youtube-downloader.savetubevideo.com / referral</b> (4 hits)<br><b>meine downloads anzeigen</b> (3 hits)<br><b>understanding piwik</b> (3 hits)<br><b>bbw highway .com</b> (2 hits)<br><b>imgsrc</b> (2 hits)<br><b>piwik</b> (2 hits)<br><b>piwik deutsch</b> (2 hits)<br><b>piwik exporting reports</b> (2 hits)<br><b>piwik failed to load html file</b> (2 hits)<br><b>piwik not tracking</b> (2 hits)<br><b>piwik sharepoint</b> (2 hits)<br><b>premature end of data</b> (2 hits)<br><b>vertrag mit piwik zur auftragsdatenverarbeitung</b> (2 hits)<br><b>wp-piwik einrichten</b> (2 hits)<br><b>"edt 2014 x86_64" ext:php</b> (1 hits)<br><b>"failed to load html file" piwik plugins/sitesmanager/templates/index.html</b> (1 hits)<br这篇关于piwik api: 调用api数据的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
