Question

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:	esta.jpg");

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

这里是上载。网址是:www.un.org。

$uploads_dir =  ./files/ ; //Directory to save the file that comes from client application.
foreach ($_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");
 }

我不会从上述法典中发现任何错误。但它似乎没有发挥作用。为什么? 哪怕是失踪?

Answer 1

您目前的PHP代码是处理多种文档上载,但您是 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");
}
?>

您还需要确保有<代码>/files的名录。

我已经用你的C#代码测试了上述PHP代码,并做了完美的工作。

For more information on handling file uploads, refer to the PHP documentation.
关于上载<>、、 和C#和PHP的文档的更多信息,这里有一些有用的链接:

Upload file with HTTPWebrequest (multipart/form-data)

用超文本格式Variables使用射线

PHP: 重载多卷

如果你想用一些简单的办法来上载多份档案,那么你只是把一个文件上载到upload.php in a C# loop。

您的《加拿大法典》似乎正确,但你试图利用全球“国际会计准则”的“假设”钥匙查阅文件。看来,这在你的碎石法中并未具体指明。我不知道如何这样做。您可以设法了解如何在您的实验室中点名,具体做法是,在全球或利用阵列“钥匙”功能,对您进行打印。
