Implement or show how to upload files to your sketch #7
Description
Hi! :) I was wondering if it's possible to upload files to the server?
I tried this:
import http.*;
import java.util.Map;
SimpleHTTPServer server;
void setup() {
SimpleHTTPServer.useIndexHtml = false;
server = new SimpleHTTPServer(this);
TemplateFileHandler templateHandler = new ResultFromPost("index.ftl");
server.createContext("", templateHandler);
}
class ResultFromPost extends TemplateFileHandler {
public ResultFromPost(String templateFileName) {
super(templateFileName);
}
void createMap() {
Map<String, String> params = queryToMap();
println(params.get("image"));
}
}
And this is the ftl
<!DOCTYPE html>
<html>
<header></header>
<body>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="image">
<input type="submit" value="Upload" />
</form>
</body>
</html>
The data is there printed in the console, so that part works, but the data must be decoded. Does SimpleHTTPServer come with any helper functions for this?
A nice Example for this feature would be a tiny image gallery. Allow uploading images, and then show them as thumbnails in the html. Maybe convert them to black and white in Processing before saving them :)
Here some info about the decoding part:
