Android 将音频和视频文件上载到服务器

我想上传音频视频和图像文件到服务器上使用php和android。 我已经阅读了很多代码和示例，但没有找到上传音频和视频的合适示例。 我已经成功完成了图像上传部分，所以请帮助我上传视频和音频部分。我想将上传大小设置为最大10MB音频和视频

这是我尝试上传音频但没有得到的代码

        }
      }
}

我没有这个密码

dos.writeBytes("Content-Disposition: form-data; name="";filename="" + selectedPath + """ + lineEnd);

我应该如何修改此语句

PHP文件

    $target_path = "uploads/";



$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);



if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {

    echo "The file ".  basename( $_FILES['uploadedfile']['name']).

    " has been uploaded";

} else{

    echo "There was an error uploading the file, please try again!";

}

多谢各位

这是logcat

替换这个

dos.writeBytes("Content-Disposition: form-data; name="";filename="" + selectedPath + """ + lineEnd);

与

因为在您的php文件中，您已经通过了

uploadedfile

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

因此，您必须将上载文件作为名称的参数传递

---

希望这能对您有所帮助。

尝试下面的解决方案，让我看看会发生什么？检查我在这里添加的logcat@InnocentKiller在替换这一行后您会遇到此错误吗？@InnocentKiller是的，在替换我遇到此错误的行后，您的服务器目录中是否有名为

uploads

的文件夹。如果没有，则手动创建。

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
