function sendPost($url,$postData){ $postdata = http_build_query($postData); $options = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-type:application/x-www-form-urlencoded', 'content' => $postdata, 'timeout' => 15 * 60 // 超时时间(单位:s)) ); $context = stream_context_create($options); $result = file_get_contents($url, false, $context); return $result; }$url = "http://chepiao.sinaapp.com/api.php?act=remain";$data = array( "date"=>"20131220", "startStation"=>"北京", "arriveStation"=>"天津");$result = sendPost($url, $data); $obj = json_decode($result);$result就是返回来的数据,就是解析不了,用json_decode($result);解析成的是NULL
回复讨论(解决方案)
来人帮解析一下
打印下$result看下结果
真够可以的
gbk环境看到
{"title":"北京 - 天津 ??0娆¤溅锛?","errMsg":"????ㄥ?锛??绋????璇??"}
utf-8环境看到
{"title":"???? - ??
连csdn都不能接受这种字符集的错乱
utf-8环境看到
真奇葩
echo json_last_error();
结果是4,说明格式不正确
于是把返回的东西扔http://jsonlint.com/检测,报错,发现是换行的问题
print_r(json_decode(str_replace("\n"," ",$result)));
结果就好了。
多谢各位 json_last_error没学会用,结贴了

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
