我的json_decode返回null，我想我在发布这篇文章之前已经尝试了一切。请建议我。
我使用Windows Live REST API来读取用户相册和照片。 json_decode非常适合解码来自所有其他Windows Live端点的响应，但不能解析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，它包含许多\ r和\ n。甚至在线之间。所以我把它全部清理干净了。
1.I修剪它
$albumPhotosResponse = trim($albumPhotosResponse);
2.删除所有\n和\r
$albumPhotosResponse = str_replace(array("\n", "\r"),"",$albumPhotosResponse);
3.只是为了确保没有额外的空间我这样做
$albumPhotosResponse = preg_replace('!\s+!', '', $albumPhotosResponse);
我搜索了一下，发现许多开发人员的问题是json值不是UTF-8编码的。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。杰森是对的。但是当我尝试json_decode()时。它返回null :(
请告诉我如何解决这个问题。
谢谢。
这是JSON文档本身：
