百度编辑器ueditor全网搜不到解决方案的问题，ueditor配置文件中php/controller.php一个接口文件，请求没有返回，竟然下载了。

Question

thinkphp5开发的cms系统，部署在百度虚拟主机nginx操作系统

今天把程序放在了百度虚拟主机上，访问前后台都正常，就是ueditor配置出了问题，ueditor下面有个php/controller.php文件，这个文件其实是个返回数据的文件(如图)

正常之前放在西部数码上的，请求这个文件（链接为：http://www.0000.com/static/admin/plugins/ueditor/php/controller.php?action=config）返回的是一个json（如图）

但是刚在百度虚拟主机上，访问同个链接竟然自动下载controller.php(如图)

，所以这个问题一直导致报错信息后台配置项返回格式出错，上传功能将不能正常使用！，我搜了一下好像是nginx操作系统不识别.php，但是其他.php文件都可以访问，就是ueditor的这个.php没有，网上找了一天了。没找到相关问题的解决方法，请求给解答一下？急啊

Answer 1

已经解决，由于是nginx操作系统，存在拦截器读取.php文件失败。想到另一个办法，在ueditor配置文件的php/controller.php，移到正常项目的路径，本来这就是个返回接口的文件，我是TP5。在admin/contrlooer新建Ueditor.php，把controller.php复制放在里面，注意修改namespace之类的。再次访问就可以正常访问返回json了。然后这个文件就作为编辑器上传文件的接口了，修改里面的一下验证size,后缀的，自己去写就行了。在初始化ueditor编辑器的时候，增加一个参数

serverUrl:"{:url('Ueditor/index')}",

就行了。
注意有个config.json的文件，用它的绝对路径就行了。
下面是ueditor.php，上部（在admin/contrlooer新建Ueditor.php）
