从我的VB.net应用程序上传到我的网站 [英] Upload to my website from my VB.net application
问题描述
我正在设计一个网站,我将从VB.net程序中将内容上传到该网站.我还设置了内容,以便您可以从以下页面之一上传内容:
I'm designing a site that I'll be uploading content to from my VB.net program. I've also set up the stuff so you can upload content from one of the pages:
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
Choose a file to upload: <input name="uploaded_file" type="file" />
<input type="submit" value="Upload" />
</form>
除了我的VB.net程序之外,是否可以使用相同的方法进行上传?我正在使用VB.net,因此所有.net示例和解决方案都是可以接受的:)
Is there any way to upload using this same method, but with my VB.net program? I'm using VB.net so all .net examples and solutions are acceptable :)
这是upload.php的副本:
Here is a copy of what upload.php is:
<?php
//Check that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
//Check if the file is JPEG image and it's size is less than 350Kb
$filename = basename($_FILES['uploaded_file']['name']);
$ext = substr($filename, strrpos($filename, '.') + 1);
if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&
($_FILES["uploaded_file"]["size"] < 350000)) {
//Determine the path to which we want to save this file
$newname = dirname(__FILE__).'/uploads/'.$filename;
//Check if the file with the same name is already exists on the server
if (!file_exists($newname)) {
//Attempt to move the uploaded file to it's new place
if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {
echo "It's done! The file has been saved as: ".$newname;
} else {
echo "Error: A problem occurred during file upload!<br /><br /><a href='index.php'>Try Uploading Again</a>";
}
} else {
echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists! That's our fault. Please be patient while we fix it :)<br /><br /><a href='index.php'>Try Uploading Again</a>";
}
} else {
echo "Error: Only .jpg images under 350Kb are accepted for upload<br /><br /><a href='index.php'>Try Uploading Something Smaller</a>";
}
} else {
echo "Error: No file uploaded";
}
?>
推荐答案
正如评论中所说,您需要System.Net.WebClient
.您的问题可能是由于没有正确的标题引起的
As was said in comments you need System.Net.WebClient
. Your problems can be caused by not having proper headers
.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)")
.Headers.Add(System.Net.HttpRequestHeader.ContentType, "application/x-www-form-urlencoded")
.Headers.Add(System.Net.HttpRequestHeader.ContentLanguage, "en-gb")
或通过不正确处理cookie的方法: 可以完成!:WebClient:处理Cookie
Or by not handling cookies properly: It Could Be Done!: WebClient: Handling Cookies
