如何在PHP中包含/调用此Javascript文件？

Question

我正在编写一个PHP脚本，它使用Twitters API来获取JSON中的推文响应。 然后我在这个JSON中使用id作为Twitter的widgets.createTweet（）函数中的参数。

官方Twitter文档可以在这里找到。

我相信问题是我试图在我的PHP脚本中包含Twitter widgets.js文件。

这是我的整个PHP脚本，其中包含我的密钥和令牌：

<?php

echo "<h2>Simple Twitter API Test</h2>";
require_once('TwitterAPIExchange.php');

$settings = array(
    'oauth_access_token' => ""
    'oauth_access_token_secret' => ""
    'consumer_key' => ""
    'consumer_secret' => ""
)

$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$requestMethod = "GET";
if (isset($_GET['user']))  {$user = preg_replace("/[^A-Za-z0-9_]/", '', $_GET['user']);}  else {$user  = "iagdotme";}
$getfield = "?screen_name=$user&count=$count";
$twitter = new TwitterAPIExchange($settings);
$string = json_decode($twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest(),$assoc = TRUE);
if(array_key_exists("errors", $string)) {echo "<h3>Sorry, there was a problem.</h3><p>Twitter returned the following error message:</p><p><em>".$string[errors][0]["message"]."</em></p>";exit();}

$number_tweets = count($string['statuses']);

//                  THIS IS THE PROBLEM AREA      ///////////

echo "<script sync src='https://platform.twitter.com/widgets.js'></script>"

echo "<div class='cols'>";
foreach ($tweet_array['statuses'] as $tweet ) {
  $id = $tweet["id"];
  echo "<div class='grid-item'><div id='container-$id'></div></div>";
$js_array[] = "twttr.widgets.createTweet('$id', document.getElementById('container-$id'));";
}
echo "</div>";
echo '<script>';
$t = 1;
foreach ($js_array as $js) {
  echo $js;

  $t++;
}
echo '</script>';
?>

我相信问题是我试图在https://platform.twitter.com/widgets.js中包含js文件

在我看来，这里的其他一切都应该有效。 当我尝试在浏览器中打开它时，这个php文件没有给我任何错误。 我被卡住了。

我要对这段代码做些什么：

• 对Twitter进行API调用并检索一组推文
• 使用这些推文中的id来传递

我该怎么做呢：

• 使用php我在一个开源的php库/ api包装器的帮助下对Twitter进行了成功的API调用。

• 将JSON响应存储在一个数组中，循环遍历该数组获取tweet id（json中每条推文的属性）

• 使用这些id作为twitter的createTweet函数的参数

我的问题是：

我认为问题是，当我使用twttr.widgets.createTweet（） js函数时，我的代码不知道我的意思，因为没有正确包含htts：//platform.twitter.com/widgets.js。

重申一下，这是我试图包含该文件的地方：

echo "<script sync src='https://platform.twitter.com/widgets.js'></script>"

这件作品是否包括在内？ 如果是这样，还有其他东西突然出现错误吗？

以下是来自twitter API调用的JSON响应示例。

如果你想知道运行时使用的是什么语法错误，请使用phpstorm。

我修复错误，现在代码看起来像这样，你的脚本将在php文件中连接。

<?php

echo "<h2>Simple Twitter API Test</h2>";
require_once('TwitterAPIExchange.php');

$settings = [
    'oauth_access_token' => "",
    'oauth_access_token_secret' => "",
    'consumer_key' => "",
    'consumer_secret' => ""
];

$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$requestMethod = "GET";
if (isset($_GET['user'])) {
    $user = preg_replace("/[^A-Za-z0-9_]/", '', $_GET['user']);
} else {
    $user  = "iagdotme";
}

$getfield = "?screen_name=$user&count=$count";
$twitter = new TwitterAPIExchange($settings);
$string = json_decode($twitter->setGetfield($getfield)
    ->buildOauth($url, $requestMethod)
    ->performRequest(),$assoc = TRUE);
if(array_key_exists("errors", $string)) {
    echo "<h3>Sorry, there was a problem.</h3><p>Twitter returned the following error message:</p><p><em>".$string["errors"][0]["message"]."</em></p>";exit();
}

$number_tweets = count($string['statuses']);

?>
<script sync src='https://platform.twitter.com/widgets.js'></script>

<?php

echo "<div class='cols'>";
foreach ($tweet_array['statuses'] as $tweet ) {
    $id = $tweet["id"];
    echo "<div class='grid-item'><div id='container-$id'></div></div>";
    $js_array[] = "twttr.widgets.createTweet('$id', document.getElementById('container-$id'));";
}

echo "</div>";

?>
