Magento自定义rest API适用于localhost但在服务器上引发内部服务器错误

Question

我们创建了一些在localhost上运行正常的自定义API，但在服务器上，其中一个给出了内部服务器错误。

在错误日志中我们得到了这个：

[Fri Jul 14 16:06:46.397538 2017] [core:error] [pid 7894:tid 139744927274752] [client 5.2.174.151:40133] malformed header from script 'index.php': Bad header: content-type

在API中，我们将标题内容类型设置为application / json

<?php header('content-type','application/json'); ?>

localhost和server上的php版本是相同的5.6.31

这就是htaccess：

DirectoryIndex index.php
