washapp

Web Api Self Host App

This template program is written in VB.Net. You can just change the content as you need.

Main page is html/first.html. Css files should be put in css/ folder. Javascript files should be put in js/ folder. Images files(.jpg, .png, .gif) should be put in img/ folder. Plugins files should be put in plugins/ folder.

Have fun!

Change

1. Add StaticController to serve static file at any folder.
2. Add PluginsController to serve plug-in functionality.
3. Server read port setting from config.json.

Introduction

Http Port

WASHApp will serve http function at port 32767 by default or read setting from config.json.

Security

If you run under win7 or win server 2008, following command need to be executed to allow port to be

opened.

netsh http add urlacl url=http://+:32767/ user=machine\username

Configuration

config.json give simplest configuration that can define window width and height, static file type, and plugin function.

{
  "window.w":800,
  "window.h":400,
  "port":32767,
  "static_support":{
    ".txt":"text/text",
    ".log":"text/text",
    ".js":"text/javascript",
    ".png":"image/png",
    ".jpg":"image/jpg",
    ".gif":"image/gif"
  },
  "plugins":{
    "plugins_test.py":"1"
  }
}

Static file

Because some reason, path can not support ".." as parent folder. I walked around to serve file in other folder by assign special string. For example:

static/p/plugins/list_parent_dir.txt

is point to:

static/../plugins/list_parent_dir.txt

Plug-in

Plugin functionality is provided by execute an executable file like .exe or .py. In order to do this, config.json should add a section plugins as following:

"plugins":{
    "plugins_test.py":"1"
}

Inside plugins, It should be a name/value pair list. Name is executable name that washapp will call by using another process. Value is indicate whether washapp wait execution complete or not. 1 means wait while 0 means no wait.

Typically, call executable and get result like following code:

function get_plugins_test() {
    $.get("static/p/plugins/list_parent_dir.txt", function (data) {
    
        var y = "";
        data = data.split('\n');
        for (x in data) {
            y += x + ' ** ' + data[x] + '<br />';
        }
        $('#display').html(y);
    }, 'text');
}

$.get("plugins/plugins_test.py", function (data) {
    get_plugins_test();
}, 'json');
