在我的代码中需要更改dropbox api输出 [英] dropbox api output needs to be changed in my code
本文介绍了在我的代码中需要更改dropbox api输出的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用Dropbox Core API提供的php SDK。一切工作正常...但是需要更新输出...我正在获取图像的名称作为输出...但是我需要对图像本身进行播放...
I am using php sdk provided by Dropbox Core API. Everything is working fine... but need to update the output... I am getting image's name as an output... But I need to diaplay images itself...
从以下行编辑此问题：
我面临的问题是我的api仅获取一个文件夹的数据（图像），并且令人惊讶的是，该文件夹是由应用程序本身创建的！！！！我对index.php文件进行了一些更改，以获得所需的输出，但似乎不起作用。请看下面我的index.php（更新文件）：
Editing this question from this line: The problem I am facing is my api is fetching only one folder's data(Images) and surprisingly this folder is created by the app itself...!!! I have made some changes to my index.php file to get my desired output but it seems not working. Please look at my below index.php (Updated file):
