I have a Classic ASP page with an <input type="file"/> control. When a file with Chinese filename is being uploaded to the server, it gets garbled into some weird characters.
Original FileName: 你好，你能听到我.jpg
Filename in server: ä½ å¥½ï¼Œä½ èƒ½å¬åˆ°æˆ‘.jpg
Is there a way in which we can restrict this? My requirement is to let the user download the uploaded file later, and the original filename must stay intact.
I have added this in web.config:
<globalization requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8"/>
All my pages have:
<% codepage="65001" %>
<% Response.charset ="utf-8" %>
<% If Form.State = 0 Then
Form.CharSet = Response.CharSet%>
<html>
<head>
<title>Document Upload Wizard</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
I have a first page FileUpload1.asp which has the <input type="file"> and then a Submit button which navigates to FileUpload2.asp where this is how the upload is happening:
Set Directory = Server.CreateObject("ActiveFile.Directory")
Set Post = Server.CreateObject("ActiveFile.Post")
Set Post.Directory = Directory
Directory.Path = "D:\ApplicationDocuments\TEMPFOLDER\Product_Live\"
Post.Upload Directory.Path
In the server I get the filename garbled.

I'm using Javalin to serve my static web pages, which I've never done before. I know it's possible in Nginx to remove the .html from the end of your url but still route to the correct page, for example mysite.com/login would replace mysite.com/login.html but still point towards my login.html file. Is this possible in Javalin?
I've tried looking into the config (StaticFileConfig) but couldn't seem to find anything that would solve this problem
Here are two examples of what was discussed in the comments to the question, for future visitors:
The first example assumes there is a simple HTML file in the application's resources/html folder.
The test.html file:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div>Hello world.</div>
</body>
</html>
The /test handler:
public static void main(String[] args) {
Javalin.create(config -> {
})
.get("/test", ctx -> {
ctx.contentType(ContentType.TEXT_HTML);
InputStream in = App.class.getResourceAsStream("/html/test.html");
ctx.result(in);
})
.start(8080);
}
If you choose to configure Javalin with Thymeleaf, and if you place your HTML file in the default location expected by Thymeleaf (resources/thymeleaf), then you can do this:
.get("/test", ctx -> {
Map<String, Object> model = new HashMap<>();
ctx.render("test.html", model);
})
In this case, the model used by Thymeleaf for rendering is empty because you don't need to make any substitutions in your HTML file (it's not a template). But it's a short step from this to using dynamic Thymeleaf templates.
I followed what andrewJames was saying and that worked for me. I was hoping there would be a cleaner way of doing this, as I'm just copy pasting the same code for every endpoint and changing the file path, but this works.
Trying to determine how to revise the atlas.ioread() function from the Azure Maps tutorial below to read the data locally on my windows machine.
atlas.io.read(window.location.origin + '/Common/data/Gpx/Route66Attractions.xml')
Does the 'window.location.origins +' work with local files?
I have nested the .xml file similarly to the above string, relative to the html file, however, it does reading the file when the map is launched.
Azure Maps Tutorial:
https://github.com/Azure-Samples/AzureMapsCodeSamples/blob/master/AzureMapsCodeSamples/Spatial%20IO%20Module/Load%20spatial%20data%20(simple).html
That function won't be able to access local files directly as the URL must be a http or https URL. There are a couple of approaches you can take.
If you plan to host the file later, you can host it locally on localhost and then have a URL pointing to it.
If you want to access local files, you will first need to load the file into your app using the file input tag and the FileReader class. Once you have the raw file data (text), you can pass that into the atlas.io.read function and it will process if for you. Here is a simple example:
<!DOCTYPE html>
<html>
<head>
<title>Read Text File</title>
<!-- Add references to the Azure Maps Map control JavaScript and CSS files. -->
<link rel="stylesheet" href="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.css" type="text/css" />
<script src="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.js"></script>
<!-- Add reference to the Azure Maps Spatial IO module. -->
<script src="https://atlas.microsoft.com/sdk/javascript/spatial/0/atlas-spatial.min.js"></script>
</head>
<body>
<input type="file" name="inputfile" id="inputfile">
<script type="text/javascript">
window.onload = function() {
var input = document.getElementById('inputfile');
input.addEventListener('change', function() {
var fr = new FileReader();
fr.onload = function(){
atlas.io.read(fr.result).then(function(r){
//r is the parsed data. Do something with it.
});
}
fr.readAsText(input.files[0]);
});
});
</script>
</body>
</html>
I want to use the Wpf webBrowser control to render math equations.
I've downloaded MathJax, and included it in my Visual studio project.
I've tryed to load one of the MathJax example. This is the html code i'm using:
<!DOCTYPE html>
<html>
<head>

When
<math xmlns="http://www.w3.org/1998/Math/MathML">

there are two solutions to

<mo>+</mo> <mi>b</mi><mi>x</mi>

and they are

Everything is working fine with the following code:
string curDir = Directory.GetCurrentDirectory();
this.webBrowser1.Navigate(new Uri(String.Format("file:///{0}/test-1.html", curDir)));
But if i try this code:
string s = File.ReadAllText(Directory.GetCurrentDirectory() + "\\test-1.html");
this.webBrowser1.NavigateToString(s);
i get a Script Error:
An error has occurred in the script on this page.
Line: 1
Char: 1
Error: Syntax Error
Code: 0
URL: about:MathJax-Reduced/unpacked/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full
What's wrong? It would be really helpful to use something similar to the last code, so i can avoid to save a file just to load it...
Note that the URL in the error is about:MathJax-Reduced/unpacked..., which is an about URL not the file:// URL that you had in the first case. I suspect that is the cause of the problem. That suggests that the NavigateToString function is using about:blank or a similar URL as the base URL for the page, so MathJax is getting the wrong path to itself. Note that you lose the actual page location when reading it from the file and loading it as a string. That means you may have to load MathJax from an absolute URL rather than a relative one (i.e., include the file:// and path to the MathJax-Reduced directory).
I have setup and installed the Composite C1 4.0 beta, along with the latest MVC Player build (from 12/7/2012 nightly), but whenever I call the MVCPlayer function, it outputs additional tags on the page. For example, I am calling a MVCPlayer function for breadcrums. This is the output:
..... before breadcrum content .....
<a name="site-nav" class="screen-reader"></a>
<html xmlns="http://www.w3.org/1999/xhtml">
<head />
<body>
<html>
<head />
<body>
<!-- START BREADCRUM SECTION -->
<ul id="breadcrumbs">
<li>Homep</li>
<li>Events</li>
</ul>
<!-- END BREADCRUM SECTION -->
</body>
</html>
</body>
</html>
<div class="clear"></div>
</div>
..... rest of page .....
As you can see, it is in the middle of the page. The MVCPlayer is returning an XDocument in the render function. So, how do I get rid of the extra tags before the START & END BREADCRUM SECTION comments? The page renders fine, but this is impacting the ability for me to use a page filter to add additional content to the output, such as switching out image tag src's so I can use a jquery script to perform lazy loading images (see http://www.appelsiini.net/projects/lazyload).
Any thoughts?
Thanks!
Chad
The output of the actual breadcrums page is simply <ul><li>...</li></ul>, and there are no errors in the log files. The MVC Player actually adds the additional code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head />
<body>
</body>
</html>
In the Player.cs file, here is the code:
var sbHtml = new StringBuilder();
sbHtml
.Append(#"<html xmlns=""http://www.w3.org/1999/xhtml"">
<head/>
<body>")
.Append(responseWriter.ToString())
.Append(#"
</body>
</html>");
try
{
return XDocument.Parse(sbHtml.ToString());
}
I was able to modify the /Renderers/Page.aspx.cs and changed this line to "strip" out the extra tags:
Original:
xhtml = _renderingContext.FormatXhtml(xhtml);
Updated:
xhtml = _renderingContext.FormatXhtml(xhtml.Replace(#"<html xmlns=""http://www.w3.org/1999/xhtml"">", "").Replace("<html>", "").Replace("<head />", "").Replace("<head></head>", "").Replace("<body>", "").Replace("</body>", "").Replace("</html>", ""));
I'm sure there is a better solution than this? :)
Chad
It could be that somewhere else on the the page you have markup which makes the whole result document and invalid XHTML, and therefore the system cannot process it correctly.
Try to
a) Check the log files to see if there any related warnings
b) validate the output xhtml http://www.xmlvalidation.com/
I’m trying to get special characters like the German Umlaut (ä, ö, ü) working with the Google App Engine, but sadly it dosen't work. The Eclipse text file encoding is set to UTF-8, I use <meta http-equiv="content-type" content="text/html; charset=UTF-8"> in my index.html and the web.xml is also using encoding="utf-8".
If I compile my project locally, the characters are shown correctly. If I deploy it to the google appspot the characters are shown like this: ��. I checked also the Browser encoding, this is set to UTF-8, what did I miss?
Edit
Here is a example which works locally but not online:
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>ä ö ü</title>
</head>
<body>
<form name="profile" action="">
<select name="p" size="1">
<option value="1">ä</option>
<option value="2">ö</option>
</select>
</form>
</body>
Edit2
I could isolate the problem. At the start I use the google channel api to communicate with the clients. Here I write the token to the users. This is the problem. Here is the code:
I guess I have to convert to UTF-8, but where?
FileReader reader = new FileReader("index.html");
CharBuffer buffer = CharBuffer.allocate(16384);
reader.read(buffer);
reader.close();
String index = new String(buffer.array());
index = index.replaceAll("\\{\\{ token \\}\\}", token);
index = index.replaceAll("\\{\\{ user \\}\\}", account);
resp.getWriter().write(index);
Why the characters are not shown correctly online?
FileReader always uses the platform default encoding. Use
InputStreamReader(new FileInputStream("index.html"), "UTF-8")
