Answer 1

Hier ist ein gutes Beispiel für die Verwendung der PHP-API mit cURL von WikiMedia selbst.

Zuerst Anmeldung:

/** 
* Configuration 
* ------------------------------------------------- 
*/ 
// Start session 
session_start(); 

// Login 
$app['username'] = "Example"; 
$app['password'] = "mypassword"; 

// Version 
$app["version"] = "0.0.1-dev"; 

// Last modified 
date_default_timezone_set("UTC"); 
$app["lastmod"] = date("Y-m-d H:i", getlastmod()) . " UTC"; // Example: 2010-04-15 18:09 UTC 

// User-Agent used for loading external resources 
$app["useragent"] = "My First Tool " . $app["version"] . " (LastModified: " . $app["lastmod"] . ") Contact: myfirsttool (at) example (.) com"; 

// Cookie file for the session 
$app["cookiefile"] = tempnam("/tmp", "CURLCOOKIE"); 

// cURL to avoid repeating ourselfs 
$app["curloptions"] = 
    array(
     CURLOPT_COOKIEFILE => $app["cookiefile"], 
     CURLOPT_COOKIEJAR => $app["cookiefile"], 
     CURLOPT_RETURNTRANSFER => 1, 
     CURLOPT_USERAGENT => $app["useragent"], 
     CURLOPT_POST => true 
    ); 

$app["apiURL"] = "http://www.mediawiki.org/w/api.php"; 

dann die Anmeldung, die Cookies zu tun:

/** 
* Login 
* ------------------------------------------------- 
*/ 

// Info: http://www.mediawiki.org/wiki/API:Login 

$postdata = http_build_query([ 
    "action" => "login", 
    "format" => "php", 
    "lgname" => $app["username"], 
    "lgpassword" => $app["password"], 
]); 

$ch = curl_init(); 
    curl_setopt_array($ch, $app["curloptions"]); 
    curl_setopt($ch, CURLOPT_URL, $app["apiURL"]); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); 
    $result = unserialize(curl_exec($ch)); 
    if(curl_errno($ch)){ 
     $curl_error = "Error 003: " . curl_error($ch); 
    } 
curl_close($ch); 
//print_r($result);//die;//DEBUG 

// Basic error check + Confirm token 
if ($curl_error){ 
    $domain_error = $curl_error; 

} else if ($result["login"]["result"] == "NeedToken") { 

    if (!empty($result["login"]["token"])) { 
     $_SESSION["logintoken"] = $result["login"]["token"]; 

     $postdata = http_build_query([ 
      "action" => "login", 
      "format" => "php", 
      "lgname" => $app["username"], 
      "lgpassword" => $app["password"], 
      "lgtoken" => $_SESSION["logintoken"], 
     ]); 

     $ch = curl_init(); 
      curl_setopt_array($ch, $app["curloptions"]); 
      curl_setopt($ch, CURLOPT_URL, $app["apiURL"]); 
      curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); 
      $result = unserialize(curl_exec($ch)); 
      if(curl_errno($ch)){ 
       $curl_error = "Error 004: " . curl_error($ch); 
      } 
     curl_close($ch); 
     //print_r($result);//die;//DEBUG 

    } else { 
     $other_error = "Error 006: Token error."; 
    } 

} 


// Check for all documented errors 
// Source: http://www.mediawiki.org/wiki/API:Login#Errors 
// Date: 2010-04-17 
if ($curl_error){ 
    $domain_error = $curl_error; 

} else if ($result["login"]["result"] == "Success") { 
    $_SESSION["login_result"] = $result["login"]["result"]; 
    $_SESSION["login_lguserid"] = $result["login"]["lguserid"]; 
    $_SESSION["login_lgusername"] = $result["login"]["lgusername"]; 

} else if ($result["login"]["result"] == "NeedToken") { 
    $other_error = "Error 005: Token error."; 

} else if ($result["login"]["result"] == "NoName") { 
    $username_error = "The username can not be blank"; 

} else if ($result["login"]["result"] == "Illegal") { 
    $username_error = "You provided an illegal username"; 

} else if ($result["login"]["result"] == "NotExists") { 
    $username_error = "The username you provided doesn't exist"; 

} else if ($result["login"]["result"] == "EmptyPass") { 
    $password_error = "The password can not be blank"; 

} else if ($result["login"]["result"] == "WrongPass" || $result["login"]["result"] == "WrongPluginPass") { 
    $password_error = "The password you provided is incorrect"; 

} else if ($result["login"]["result"] == "CreateBlocked") { 
    $username_error = "Autocreation was blocked from this IP address"; 

} else if ($result["login"]["result"] == "Throttled") { 
    $other_error = "You've logged in too many times in a short time. Try again later."; 

} else if ($result["login"]["result"] == "mustbeposted") { 
    $other_error = "Error 004: Logindata was not send correctly"; 

} else if ($result["login"]["result"] == "Blocked") { 
    $username_error = "This account is blocked."; 

} else if ($result["login"]["result"]){ 
    $other_error = "Error 001: An unknown event occurred."; 
} else { 
    $other_error = "Error 002: An unknown event occurred."; 
} 

// The tool you use may log or display the variables: 
// $other_error, $username_error and $password_error in the appropiate place 
// Such as near a login form, or in a specific debug/logfile 
// by default the errors are not outputted 
if($_SESSION["login_result"] !== "Success"){ 
    die("Login error. Have you defined app[username] and app[password] ?"); 
} 

Beispiel für den Aufbau einer Abfrage:

/** 
* Get userinfo 
* ------------------------------------------------- 
*/ 

$postdata = http_build_query([ 
    "action" => "query", 
    "format" => "php", 
    "meta" => "userinfo", 
    "uiprop" => "rights|hasmsg", 
]); 

$ch = curl_init(); 
    curl_setopt_array($ch, $app["curloptions"]); 
    curl_setopt($ch, CURLOPT_URL, $app["apiURL"]); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); 
    $result = unserialize(curl_exec($ch)); 
    if(curl_errno($ch)){ 
     Death("Error 003: " . curl_error($ch),"API connection failed."); 
    } 
curl_close($ch); 
//print_r($result);//die;//DEBUG 

// Check for usermessages 
if (isset($result['query']['userinfo']['messages'])) { 
    $api['hasmsg'] = true; 
    $api['hasmsghtml'] = '<div class="usermessage">You have new messages !</div>'; 
} else { 
    // User does not have new messages 
} 

Und schließlich, wie man sauber up die Sitzung:

Answer 2

Ich habe versucht, das, und es funktioniert entweder

 public function callWiki($url) 
{ 
$ch = curl_init(); 
curl_setopt_array($ch, array(
CURLOPT_URL => $url, 
CURLOPT_RETURNTRANSFER => true, 
CURLOPT_SSL_VERIFYPEER => false, 
CURLOPT_SSL_VERIFYHOST => 2 
)); 
$result = curl_exec($ch); 
curl_close($ch); 
return $result; 
} 


public function getAllCategories() 
{ 

    $api = 'https://en.wikipedia.org/w/api.php? action=query&titles=watch&prop=categories&format=json'; 
    //get query result 
    $api_response = $this->callWiki($api); 
    $results = json_decode($api_response, true); 

}
