returning json from the lastfm api

本文关键字：lastfm api the from json returning | 更新日期: 2023-09-27

所以我试图创建一个jquery/ajax自动完成表单，使用最后一个。fm api自动完成歌曲的标题，无论用户键入，我的问题是，我似乎不能得到最后的fm数据以适当的json格式返回。这是我的jquery插件(链接到自动完成)希望返回的格式:

{
    "suggestions": [
        { "value": "United Arab Emirates", "data": "AE" },
        { "value": "United Kingdom",       "data": "UK" },
        { "value": "United States",        "data": "US" }
    ]
}

这是我在PHP脚本中所做的将json返回给自动完成插件:

                $titleName = "what's my age";
                $limit = 1;
                $results = Track::search($titleName, $limit);
                print_array($results);
                echo "<ul>";
                while ($title = $results->current()) {
                    echo $limit;
                    echo "<li><div>";
                    echo "Artist: " . $title->getArtist() . "<br>";
                    echo "Album: " . $title->getAlbum() . "<br>";
                    echo "Duration: " . $title->getDuration() . "<br>";
                    echo "getWiki: " . $title->getWiki() . "<br>";
                    echo "name: " . $title->getName() . "<br>";
                    echo "</div></li>";
                    $jsonArray['suggestions'] = array('Name'.$limit => $title->getName(), 'Artist'.$limit => $title->getArtist());
                    $limit++;
                    $title = $results->next();
                }
                echo "</ul>";
                print_array($jsonArray);
                echo json_encode($jsonArray);

echo和print语句只是用于测试，但这是json_encode返回的内容:

{"suggestions":{"Name2":"Blink vs. Jay-Z - what's my age again","Artist2":"Dj Tech1"}}

，这是返回的内容(通过echo测试):

1
Artist: Blink 1-82
Album: 
Duration: 0
getWiki: 
name: What's My Age Again?
2
Artist: Dj Tech1
Album: 
Duration: 0
getWiki: 
name: Blink vs. Jay-Z - what's my age again

所以我知道代码是正常工作的，所以是SDK自动完成等。我也明白，在while循环中删除数组每次它循环通过，我还没有解决这个问题，但除了这个问题，json没有返回请求的格式，我似乎找不到正确的方式来构建数组为了得到它在正确的格式，任何想法?

$suggestionsArr['suggestions'] = [];
foreach (range(1,3) as $key => $value) {
    array_push($suggestionsArr['suggestions'], ['name' => 'Song1', 'artist' => 'Artist1']);
}
echo json_encode($suggestionsArr);
