How do you read a string from DropBox and output it.

Okay, here is what i need to do:
I need the plugin to read the first line of a text file in my dropbox then set it to a variable so i can use it in a broadcast or print it to the console.

Here is my attempt:

Code:

 public void onEnable()
  {
    getLogger().info("To clear the chat do /clearchat");
    saveDefaultConfig();
 
  try { URL e = new URL("https://www.dropbox.com/s/8haw1eivk46759u/ClearChat.txt?dl=0");
    BufferedReader in = new BufferedReader(new InputStreamReader(e.openStream()));
    String str = in.readLine();
    getLogger().info("Test:"+str);
    in.close();}
  catch (IOException e) { }
  }

And this is the output:



How could i make this mumboJumbo of an output be the simple line in my dropbox that says 'test'?

Thankyou for the help!

EDIT:
If i could take the text form the TextFile in the Dropbox and set it into a local file that would be amazing, is there a way i could just download the txt file to the config folder and read it from there?

 

In regards to your edit, maybe something like this:

Code:java

try {
    List<String> tempArray = new ArrayList<String>();
    URL url = new URL(link.to.file);
    URLConnection con = url.openConnection();
    InputStream stream = con.getInputStream();
    String cont = "";
    int ch;
    byte[] bytes = new byte[1];
    while ((ch = stream.read()) != -1) {
        bytes[0] = (byte) ch;
        cont = cont + new String(bytes);
    }
    String[] nl = cont.split("\\/");
    if (nl.length > 0) {
        for (String string : nl) {
            getLogger().info(string);
        }
    }
    stream.close();
} catch (IOException e) {
    e.printStackTrace();
}

 

SleepyDog This might help.

 

Assuming I understand the doc, this is a much better suggestion than mine. xD

Here's how I get text from Dropbox (I set the MOTD with ProtocolLib)

Code:java

 
public static String getMOTD()
{
    URL site;
    StringBuilder motd = new StringBuilder(StringUtil.colour("&0                  &4Crimson &8Deadworks&0                  "));
    try
    {
        site = new URL("[url]https://www.dropbox.com/s/npu53an6sfmtnih/motd.txt?dl=1[/url]");
 
        try (BufferedReader in = new BufferedReader(new InputStreamReader(site.openStream())))
        {
            String line;
            while ((line = in.readLine()) != null)
            {
                motd.append("\n").append(StringUtil.colour(line));
            }
        }
    }
    catch(IOException ex)
    {
        Logger.getLogger(NewsCollector.class.getName()).log(Level.SEVERE, null, ex);
    }
 
    return motd.toString();
}
 

Note that it'll throw an exception if it can't find it, so make sure you check the link is valid too.

 

I got this error:

should the link to file be in ""?

 

Change:

Code:java

import java.awt.List;

to:

Code:java

import java.util.List;

 

How would i make this set the ClearChat.txt to the config?

 

SleepyDog

That depends on what you mean. Do you want to save the text collected to a file, or get the text from the file and do something with it?

 

Know a fix?

Ether, i would rather do something with it, eg. broadcast it
or save it and then load it from the config and broadcast it.
Witch is easier?

Could you rewrite (or show me how to) the code so it will broadcast the content of the .txt?

SleepyDog Personally, I'd just make a scheduled task every half hour or so to "refresh" it. On startup, get it and save it to config, then broadcast it all you want. Then, when the half hour comes around, check from the dropbox file again, replace the saved text with that.

So, there's two ways you can go about this:

1- You can just collect it when you want to broadcast it (If it's in a regular interval)
2- Save it to config, and load it whenever you want (For commands n' stuff)

SleepyDog I'll write it really quick. Didn't see that post

There's nothing really wrong with it. I just forgot to remove that piece of unused code.

Note this will need some changes to reflect your needs.

        @Override
        public void run()
        {
            message = getMOTD();
        }
    }, 0L, ((20*60) * 30 /*  Minutes (Set to 30 minutes here) */));
}
 
public static void broadcast()
{
    Bukkit.broadcastMessage(ChatColor.GREEN + "Scheduled message:");
    Bukkit.broadcastMessage(ChatColor.translateAlternateColorCodes('&', message));
}

And with that code, I even added support for color codes! (&aGreen, &bBlue, &6Gold, etc.)

Thankyou, i will try it. Am i okay to message you in the future if there is something i don't understand about this bit of code?

Where would i put this code?
In then onEnable()?

SleepyDog
It's a snippet of a method. Review the syntax of Java if you are further confused.

 

huh?

 

SleepyDog
The code is a method. You put in in the class. An example of a method is your onEnable. More about methods here: http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html

 

So i would put this in a new class, or would i put it in the current code?

 

SleepyDog
Depends on what you want to do with it. Put in your main class, create a different class, etc.

 

I am new to this, basically i want to ping the ClearChat.txt in my dropbox every hour then set the data in the txt file to a file in the config folder...

 

SleepyDog
Well I can't make all the decisions for you. What works for me might not work well for you.

I suggest creating a class and putting the method in.

 

Server --> Dropbox -->server -->config
I honestly thought this would be easier to do.

How would i put it in a new class? Will this be auto run or do i need to start it?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

SleepyDog
It is easy. The method is already done for you (You need to tweak it so it will work with you asformentioned. I'm just confusing you is the most probable cause on why you do not understand.

To reiterate myself you can put the method anywhere you want (Well not anywhere but in any class). It's up to you.

 

So i made a class:

Do i just paste the code into this?

 

Here's an example to clear things up.

You have your method:

Code:java

public void foo(){
/* Code code code would go go go here */
}

You can put in a class.

Code:java

public class BarClass {
    public void foo(){
 
    }
}

and to invoke, or run, it you would do:

Code:java

BarClass newInstance = new BarClass();
 
newInstance.foo();

 

So how would i start this?

 

SleepyDog
Looks alright.

 

How would i start it though?

 

SleepyDog
Because it is a static method, it belongs to the class and not to the instance. In simple terms, you don't need to make a new instance of the class to run the method.

To run it you would do:

Code:java
