我正在测试 embed.ly 并使用连接的逗号分隔链接字符串通过一个请求请求多个链接的详细信息。
就像是：
http://api.embed.ly/1/oembed?key=_key_&urls=url1,url2,url3
结果包括有关链接的一些详细信息，例如描述、标题、缩略图等。
有时没有 url 字段。在大多数情况下，有一个。该字段包含 url，据我所知，它与请求字符串中的 url 相同。
我将此 url 字段用作外键，我需要清楚地识别结果。
这是我用来从 embed.ly 加载 json 数据的函数。我只是遍历一个数组，其中包含在另一个函数中提取的一些 url，并将它们 implode() 到一个查询字符串。
收到 json 后，我检查错误，如果有错误，我将链接 bbcode 从丰富的 html 恢复为基本链接标记。
但是如果没有回传数据中使用的 url，我应该如何识别数据所属的链接？
private function getOPGdata(){
$linklist = array();
foreach ( $this->_extractions['ogp'] as &$v ) {
$linklist[] = urlencode( $v );
}
$apicall = $this->_embedkey . implode( ',', $linklist );
$data = $this->file_get_contents_curl( $apicall );
$data = json_decode( $data, true );
// we replace ogp tagged links if we don't get results
// and reverse them to normal links
$replace = array();
$replaceWith = array();
unset( $apicall );
unset( $linklist );
unset( $this->_extractions['ogp'] );
foreach ($data as &$v) {
// check for errors
if( isset( $v['error_code'] ) ){
$replace[] = '[ogp]'.$v['url'].'[ogp]';
$replaceWith[] = '[url]'.$v['url'].'[url]';
}
else {
$r = array(
'provider_url' => $v['provider_url'],
'provider_name' => $v['provider_name'],
'title' => $v['title'],
'description' => $v['description'],
'thumbnail_url' => $v['thumbnail_url'],
'html' => $v['html'],
'type' => $v['type']
);
$this->setOPGdata( $v['url'], $r );
}
}
// finally remove links with no results
$this->_text = str_replace( $replace, $replaceWith, $this->_text );
return true;
}
在 embedly.js 中，他们这样做是为了跟踪结果：
// Put everything into batches, even if these is only one.
var batches = batch(valid_urls, options.batch), self = this;
// Actually make those calls.
$.each(batches, function(i, batch){
$.ajax({
url: self.build(method, batch, options),
dataType: 'jsonp',
success: function(data){
// We zip together the urls and the data so we have the original_url
$.each(zip([batch, data]), function(i, obj){
var result = obj[1];
result.original_url = obj[0];
result.invalid = false;
keeper.notify(result);
});
}
});
});
这在 PHP 中意味着什么？
