任何类型的文件从Android设备上传到php服务器
我的代码只是将文件转换为任何类型的文件从Android设备上传到php服务器,php,android,file-upload,Php,Android,File Upload,我的代码只是将文件转换为字节数组，然后再次将其转换为Base64编码格式，这样我们就可以将其作为参数发布到URL。在服务器端，我们将其解码并将其写入文件。使用volley库与服务器建立连接。此代码应该是共享，因为我花了3天时间才找到android文件上传的解决方案 此代码有效 config.php <?php /*** * @Source: devshed * @author E-Oreo * http://forums.devshed.com/php-faqs-stickies-167
