Returns boolean(false) when try to auth to plex.tv

[vladshoob]

Good time of yours,

thanks for your work, and if I could on my own, I would gladly solve this and contribute. But I can't figure out what is wrong.

For some reason, I can not login to plex.tv, so that login call return empty response.

Maybe POST params for login has been changed.

I just confirmed that I CAN auth with the current version of the code.

Are you able to show a code snippet of how you are trying to use the lib?

[vladshoob]

$client = new PlexApi(LOCAL_SERVER_IP, LOCAL_SERVER_PORT, IS_LOCAL_SERVER_HTTPS); $client->setAuth(LOGIN, PASSWORD); $output = $client->getBaseInfo(); dd($output);

It is as in basic examples. Seems like I am receiving an empty response with login post curl.

I did face the very similar issue, but not with my PC or provider some days ago. I have tried to solve why file_get_contents($path) (or curl as well) receives empty response body ("") from graph facebook after theirs 'terms of use' update.

Hm, it is ok now =(

Probably I just had my plex media server closed or something like that.

Any ideas how to call plex.tv for info, instead of local server?

Thanks in advance!

I experience the same issue, more often than not.

Here is the code:

#!/usr/bin/env php
<?php

define('FAVORITES_TITLE', 'Share Favorites') ;
define('GENERAL_TITLE', 'Movies') ;
define('PLEX_DATABASE_SERVER', 'web') ;
define('PLEX_HOST', 'r2d2.lovelady.com') ;

//######################################################################################
// https://github.com/jc21/plex-api/blob/master/docs/Documentation.md
//######################################################################################

require_once('lovefunctions.php') ;
require_once('vendor/autoload.php') ;

use jc21\PlexApi ;
use jc21\Util\Filter ;

$pdo = $lov->pdoConnect(PLEX_DATABASE_SERVER) ;
// Get the latest login credentials for this host
$sql = <<<EOS
            SELECT cred.hostname, effective, userId, password
            FROM   plexCredentials cred
            WHERE  cred.hostname = ?
               AND effective <= CURRENT_TIMESTAMP
            ORDER BY effective DESC
            LIMIT 1
            EOS ;
$getCredsStmt = $lov->pdoPrepare($pdo, $sql) ;
$getCredsStmt->execute( [ PLEX_HOST ] ) ;
$nbrRows = $getCredsStmt->rowCount() ;
if ($nbrRows == 0) {
    printf("Could not obtain PLEX credentials from database.\nSQL: %s", $getCredsStmt->queryString) ;
    exit(1) ;
    }
elseif ($nbrRows > 1) {
    printf("%d rows returned requesting PLEX credentials from database.\nSQL: %s", $nbrRows, $getCredsStmt->queryString) ;
    exit(1) ;
    }

$creds = $getCredsStmt->fetch(PDO::FETCH_ASSOC) ;
$client = new PlexApi($creds['hostname']);
$client->setAuth($creds['userId'], $creds['password'] ) ;
if (isset($creds['token']))
    $client->setToken($creds['token']) ;

for ($i=0; $i<10; $i++) { // Because sometimes the login just doesn't work, but after several retries all is well.
    $librarySections = $client->getLibrarySections();
    if (is_array($librarySections) && isset($librarySections['Directory']) && count($librarySections['Directory'])>0) {
        break ;
        }
    if ( ! ($token = $client->getToken()))
        printf("Login was not successful.\n") ;
    elseif ($debug)
        printf("No library sections found. (%d)\n", $i) ;
    }
if ( ! ($token = $client->getToken())) {
    printf("Unable to log in.\n") ;
    exit(1) ;
    }
printf("Logged in.\n") ;

And here is sample output from a few executions:

I don't know how to troubleshoot this, to figure out what's gone wrong. How can I diagnose this?

(To get around it, I have saved the token in the database and changed the SELECT accordingly...)

            SELECT cred.hostname, effective, userId, password, token

But it's a sad day when Plex invalidates the token, which it sometimes does.

In addition, I found that when the login fails, this is not detected by PlexApi::call() so the latest curl result covers up the result from the failed login attempt. This code seems to resolve that issue (but of course not the login issue).

public function call($path, $params = [], $method = self::GET, $isLoginCall = false)
{
    if (!$this->token && !$isLoginCall) {
        $this->call('https://plex.tv/users/sign_in.xml', [], self::POST, true);
        if ( ! $this->token) // If login failed, then don't try to execute whatever's next
            return false ;   // Instead, just return false (we will anyway, in the end.
    }

[delovelady]

It looks like Plex may have changed they way a signon request should be organized. The old code:

    if ($isLoginCall) {
        $curlOptArray[CURLOPT_HTTPAUTH] = CURLAUTH_ANY;
        $curlOptArray[CURLOPT_USERPWD]  = $this->username . ':' . $this->password;
    } else {
        $curlOptArray[CURLOPT_HTTPHEADER][] = 'X-Plex-Token: ' . $this->token;
    }

works for me 0% of the time. For me, the following function solves the issue. I have rewritten the building of the curl resource into this function, and now login works for me 100% of the time (when userid and password are valid)

private function createCurlResource(string $path, array $params = [], string $method = self::GET) {

    const PLEX_TV_SIGNIN_URL = 'https://plex.tv/users/sign_in.xml' ;
    ...
    ...
    ...
    $fullURL = $path ;
    if ( ! empty($params))
        $fullURL .= '?' . $this->buildHttpQuery($params) ;
    $resource = curl_init() ;
    $curlOptArray = [
        CURLOPT_URL              => $fullURL
        , CURLOPT_AUTOREFERER    => true                  // suspect
        , CURLOPT_RETURNTRANSFER => true
        , CURLOPT_CONNECTTIMEOUT => $this->timeout        // suspect
        , CURLOPT_TIMEOUT        => $this->timeout        // suspect
        , CURLOPT_FAILONERROR    => true
        , CURLOPT_FOLLOWLOCATION => true                  // suspect
