Php Twitter上载媒体-无法验证您的身份

我在尝试将照片上传到twitter时遇到问题。我使用twitteroauth.php进行身份验证，通过api发布tweet或接收数据都没有问题。但是当我想上传一张照片时，我得到了以下错误：{“errors”：[{“message”：“无法验证您的身份”，“code”：32}]}

这是我的代码：

<?php
require_once('../include/initialize.php');

require_once('twitter/twitteroauth.php');

if(isset($_GET['access_token']) && $_GET['access_token'] != ''){
  $accesstoken = $_GET['access_token'];
}else{
  $accesstoken = TWITTER_ACCESS_TOKEN;
}

if(isset($_GET['access_token_secret']) && $_GET['access_token_secret'] != ''){
  $accesstokensecret = $_GET['access_token_secret'];
}else{
  $accesstokensecret = TWITTER_ACCESS_TOKEN_SECRET;
}

$consumerkey = TWITTER_CONSUMER_KEY;
$consumersecret = TWITTER_CONSUMER_SECRET;
$twitter = new TwitterOAuth($consumerkey, $consumersecret, $accesstoken, $accesstokensecret);

$url = $_POST['url'];
$filename = $_POST['filename'];

// function to replace file_get_contents()
function file_get_the_contents($url) {
$ch = curl_init();
$timeout = 5; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}

// original script updated with new function
$imgget = file_get_the_contents($url);

$twitter_api = "https://upload.twitter.com/1.1/media/upload.json?media=".$imgget."&type=photo";

$twitter_img = $twitter->post($twitter_api);

echo json_encode($twitter_img);

对于每个答案，您需要确保将图像数据编码到base 64中。否则，Twitter将返回错误32。您将需要以下内容：

$imgget=base64\u编码（文件获取内容（$url））；
您是否发现了问题所在？这是否回答了您的问题？
