我找到了一个PHP脚本,我试图用来从博客帖子中获取评论,似乎一切都在那里,但我无法弄清楚它为什么不能正常工作。我一直收到这个错误
Warning: Invalid argument supplied for foreach() in /Applications/MAMP/htdocs/AP-Get.php on line 33
这是脚本:
<?php
ini_set('display_errors', 'on');
$key="KEY-OMITTED";
$forum="amandapalmer";
$thread = '1009158814';
$limit = '100';
$endpoint = 'http://disqus.com/api/3.0/threads/listPosts.json?api_key='.urlencode($key).'&forum='.$forum.'&limit='.$limit.'&cursor='.$cursor;
$j=0;
listcomments($endpoint,$cursor,$j);
function listcomments($endpoint,$cursor,$j) {
// Standard CURL
$session = curl_init($endpoint.$cursor);
curl_setopt($session, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($session);
curl_close($session);
// Decode JSON data
$results = json_decode($data);
if ($results === NULL) die('Error parsing json');
// Comment response
$comments = $results->response;
// Cursor for pagination
$cursor = $results->cursor;
$i=0;
foreach ($comments as $comment) {
$name = $comment->author->name;
$comment = $comment->message;
$created = $comment->createdAt;
// Get more data...
echo "<p>".$name." wrote:<br/>";
echo $comment."<br/>";
echo $created."</p>";
$i++;
}
// cursor through until today
if ($i == 100) {
$cursor = $cursor->next;
$i = 0;
listcomments($endpoint,$cursor);
/* uncomment to only run $j number of iterations
$j++;
if ($j < 10) {
listcomments($endpoint,$cursor,$j);
}*/
}
}
?>
我想也许这是我的API密钥,但是我已经用Disqus的其他更基本的脚本检查了几次,它在这些脚本上工作正常。
答案 0 :(得分:1)
主要问题是'threads / listPosts'API端点要求您指定线程,因此存在失败响应。我修复了脚本的其他一些潜在问题并使其正常工作(参见下面的代码)。
请注意,此版本使用您的密钥。要使用您的公钥,请将“api_secret”更改为“api_key”。
<?php
ini_set('display_errors', 'on');
$key="API-SECRET-KEY";
$forum="amandapalmer";
$thread = '1009158814';
$limit = '100';
$endpoint = 'http://disqus.com/api/3.0/threads/listPosts.json?api_secret='.urlencode($key).'&forum='.$forum.'&limit='.$limit.'&thread='.$thread;
$j=0;
listcomments($endpoint,$cursor,$j);
function listcomments($endpoint,$cursor,$j) {
// Standard CURL
$session = curl_init($endpoint.$cursor);
curl_setopt($session, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($session);
curl_close($session);
// Decode JSON data
$results = json_decode($data);
if ($results === NULL) die('Error parsing json');
// Comment response
$comments = $results->response;
// Cursor for pagination
$cursor = '&cursor=' . $results->cursor->next;
$i=0;
foreach ($comments as $comment) {
$name = $comment->author->name;
$comment = $comment->message;
$created = $comment->createdAt;
// Get more data...
echo "<p>".$name." wrote:<br/>";
echo $comment."<br/>";
echo $created."</p>";
$i++;
}
// cursor through until today
if ($i == 100) {
$cursor = $cursor->next;
$i = 0;
listcomments($endpoint,$cursor,$j);
/* uncomment to only run $j number of iterations
$j++;
if ($j < 10) {
listcomments($endpoint,$cursor,$j);
}*/
}
}
