我的 json_decode 返回 null，我想我在发布这篇文章之前已经尝试了所有方法。请给我提意见。
我使用 Windows Live REST API 来读取用户相册和照片。json_decode 非常适合解码所有其他 Windows 实时端点的响应，但不能解码来自这个端点的响应:(...
$albums_url = "https://apis.live.net/v5.0/".$albumId."/photos?access_token=" . urlencode($accessToken);
$agent = "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)";
$ch = curl_init($albums_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_REFERER, "my web site domain name here");
curl_setopt($ch, CURLOPT_ENCODING, 'UTF-8');
$albumPhotosResponse=curl_exec($ch);
curl_close($ch);
当 json 响应到达时，它包含很多 \r 和 \n 。甚至是字里行间。所以我把它全部清理干净。
1.修剪
$albumPhotosResponse = trim($albumPhotosResponse);
2.删除所有\n和\r
$albumPhotosResponse = str_replace(array("\n", "\r"),"",$albumPhotosResponse);
3.为了确保没有多余的空格，我这样做
$albumPhotosResponse = preg_replace('!\s+!', '', $albumPhotosResponse);
我搜索了一下，发现对于许多开发人员来说，问题json在于没有UTF-8编码值。所以我也试过这个。
$photoAlbumsResponse = json_decode(utf8_encode($photoAlbumsResponse),true);
Chrome 会正确显示和格式化收到的 json 文档。这告诉我 json 文档的结构没有问题。我可以使用可视化工具折叠和展开 json 对象。json 是正确的。但是当我尝试json_decode()它时。它返回空:(
请告诉我如何解决这个问题。
谢谢你。
这是 JSON 文档本身：
