从C锋利客户端应用程序上传到PHP服务器 [英] Upload to PHP server from c sharp client application

问题描述

目前我有一个C锋利的应用程序（客户端应用程序）。和Web应用程序编写PHP。我想，只要在​​客户端执行特定操作来传输一些文件。下面是客户端代码把文件上传到PHP服务器..

 私人无效的button1_Click（对象发件人，EventArgs五）
 {
 System.Net.WebClient客户端=新System.Net.WebClient（）; 
 
 Client.Headers.Add（内容类型，二进制/八位字节流）; 
 
字节[]结果= Client.UploadFile（HTTP：//localhost/project1/upload.php，POST，
 @C：\test\a。 JPG）; 
 
字符串s = System.Text.Encoding.UTF8.GetString（结果为0，result.Length）; 
} 
  

下面是upload.php的文件，将文件移动..

  $ uploads_dir ='./files/'; //目录保存来自客户端应用程序的文件。 
的foreach（$ _FILES [图片] [错误]为$关键=> $错误）{
如果（$错误== UPLOAD_ERR_OK）{
 $ tmp_name的值= $ _FILES [图片] [tmp_name的值] [$关键]; 
 $ NAME = $ _FILES [图片] [名称] [$关键]; 
 move_uploaded_file（$ tmp_name的值，$ uploads_dir / $名称）; 
} 
  

我没有从上面的代码中得到任何错误。但它似乎并不奏效。为什么？我这么想吗？

解决方案

您当前的PHP代码是处理的多个文件上传，但你的C＃代码仅上传有一个文件。

您需要稍微修改你的PHP代码，删除的foreach 循环：

<预类=郎PHP prettyprint-覆盖> < PHP
$ uploads_dir ='./files'; //目录保存来自客户端应用程序的文件。
如果（$ _FILES [文件] [错误] == UPLOAD_ERR_OK）{
$ tmp_name的值= $ _FILES [文件] [tmp_name的值];
$ NAME = $ _FILES [文件] [名称];
move_uploaded_file（$ tmp_name的值，$ uploads_dir / $名称）;
}
>？;


您还需要确保 ./文件目录存在。

我已经测试过上面的PHP代码与C＃代码它完美地工作。

• 有关处理文件上传的更多信息，请参考PHP文档。




• 有关上传的详细信息 多个的 C＃和PHP文件，这里有一些有用的链接：

  
  
  

  上传与HttpWebRequest的（的multipart / form-data的）文件

  
  
  

  使用数组中的HTML表单变量

  如果你想要的东西简单的上传多个文件，你才刚刚上传一个文件来一次上传。 PHP 在C＃循环。

Currently i have a c sharp application (Client app). and a web application written php. I want to transfer some files whenever a particular action is performed at client side. Here is the client code to upload the file to php server..

private void button1_Click(object sender, EventArgs e)
{
    System.Net.WebClient Client = new System.Net.WebClient();

    Client.Headers.Add("Content-Type", "binary/octet-stream");

    byte[] result = Client.UploadFile("http://localhost/project1/upload.php", "POST",
                                      @"C:\test\a.jpg");

    string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length); 
}

Here is the upload.php file to move the file..

$uploads_dir = './files/'; //Directory to save the file that comes from client application.
foreach ($_FILES["pictures"]["error"] as $key => $error) {
  if ($error == UPLOAD_ERR_OK) {
     $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
     $name = $_FILES["pictures"]["name"][$key];
     move_uploaded_file($tmp_name, "$uploads_dir/$name");
 }

I'm not getting any errors from above code. but it does not seem to be working. Why is it? Am i missing something?

解决方案

Your current PHP code is for handling multiple file uploads, but your C# code is only uploading one file.

You need to modify your PHP code somewhat, removing the foreach loop:

<?php
$uploads_dir = './files'; //Directory to save the file that comes from client application.
if ($_FILES["file"]["error"] == UPLOAD_ERR_OK) {
    $tmp_name = $_FILES["file"]["tmp_name"];
    $name = $_FILES["file"]["name"];
    move_uploaded_file($tmp_name, "$uploads_dir/$name");
}
?>

You also need to ensure that the ./files directory exists.

I have tested the above PHP code with your C# code and it worked perfectly.

• For more information on handling file uploads, refer to the PHP documentation.

• For more information on uploading multiple files with C# and PHP, here are some helpful links:

  Upload files with HTTPWebrequest (multipart/form-data)

  Use Arrays in HTML Form Variables

  PHP: Uploading multiple files

  If you want something simple for uploading multiple files, you just just upload one file at a time to upload.php in a C# loop.
