Question

我安装了服务器（VPS）并确保启用了JSON插件。现在，我使用Laravel和一个帮助文件返回文件的代码列表。它在Localhost上工作，但不在HTTPS服务器上工作。

现在，这个echo json_encode（$ enteries）正在使用localhost（MAMP），但不能在肝脏服务器上运行。我使用的是Laravel V5.2 我得到了响应类型：text / html响应服务器。而在localhost上，它来自application / json

提前谢谢。

自己找到答案。 Laravel环境很奇怪，我所做的就是删除原生的PHP对象方法，然后就可以了。

Json在Localhost上工作但不在服务器上工作
