Question

我正在尝试将图像上传到我尝试过的服务器上
很多方法bt我没有得到准确的结果

我的 php 脚本是：-

<?php  

//include "db.php";  


if(isset($_POST['action']) && isset($_FILES['arch']))  
 {  
    if($_POST['action']==='uploadfilefromapp')   
    {  
        $newfile = basename($_FILES['arch']['name']);  
        if(move_uploaded_file($_FILES['arch']['tmp_name'], "files/".$newfile))  
        {  
            echo 'ok!';  

            /*$userfile_extn = explode(".", strtolower($_FILES['arch']['name']));  
            echo "extension = ".$userfile_extn;  

            $media_id = $_REQUEST['file_id'];  
            mysql_query("UPDATE media SET description= '$userfile_extn' WHERE media_id='$media_id'");    
            */

         }   
         else  
         {  
            echo 'fail!';  
         }  

    }   
    else   
    {  
        echo 'Go away cheater';  
    }  
}

  ?>

Answer 1

我建议将 Retrofit Library 用于 http 请求，因为我觉得您可能会发现它使用起来很简单，它允许多部分请求正文和文件上传。这是一个链接http://square.github.io/retrofit/

Answer 2

类似这样的：

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("action", "uploadfilefromapp"));

    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

进一步：这个网站有很多分段上传的例子。大多数情况下，他们使用“uploaded_file”或“uploadedfile”，而您必须使用“arch”。 'name' 是文件名。

最好的方法是实现一个 IntentService 并使用广播意图通知状态。请从 git 中查看此代码
