Php 使用android将文件上载到服务器
我一直在安卓上开发一款应用程序,它可以从sd卡上抓取一张图像,然后上传到我的服务器上。我能够将pic上传到服务器上,并将其用作示例中给出的uri”。但是,图像不会上传到我的本地主机服务器。我使用的是来自android设备的wifi的本地主机,使用uri 192.1xx.x.xxx/uploadtoserver.php。我收到了服务器响应200和OK 我已经在谷歌上搜索了3天的答案和研究结果,但都没法实现 我的代码: Java部分:Php 使用android将文件上载到服务器,php,android,apache,Php,Android,Apache,我一直在安卓上开发一款应用程序,它可以从sd卡上抓取一张图像,然后上传到我的服务器上。我能够将pic上传到服务器上,并将其用作示例中给出的uri”。但是,图像不会上传到我的本地主机服务器。我使用的是来自android设备的wifi的本地主机,使用uri 192.1xx.x.xxx/uploadtoserver.php。我收到了服务器响应200和OK 我已经在谷歌上搜索了3天的答案和研究结果,但都没法实现 我的代码: Java部分: public class UploadToServer exte

由于它在一台服务器上工作,我认为这是一个服务器端问题
PHP部分
<?php
$target_path1 = "var/www/images/"
$target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
echo "Success";
} else{
echo "fail";}
?>
看起来您引用的是一个相对目录:var/www/images/
,如果您的php文件首先位于/var/www/
中,它将指向/var/www/var/www/images/
,我怀疑您的意图
只需更改
$target\u path1
使其成为绝对路径/var/www/images/
您是否解决了此错误并获得了输出?在我的示例中,它显示“已开始上载”,但在此之后没有失败或成功消息它显示“已开始上载”消息“但是很长一段时间后也没有什么事情发生,我检查了我的网络连接,它很好,我的文件大小也很小。
<?php
$target_path1 = "/var/www/images/"
$target_path1 = $target_path1 . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $target_path1)) {
echo "Success";
} else {
echo "fail";
}
?>
