Node-Webkit无法打开文件

Question

First I'd like to say thanks for taking the time to read this. I am trying to open a JSON file that is in the following directory structure:

#--> Root Folder
   --> App.exe
  #--> Configuration
      ---> JSON File

So I used the Code:

var ConfigFile = "./Configuration/JSON.json";

Followed by:

var fs = require('fs');
var file_content = fs.readFileSync(ConfigFile);
var content = JSON.parse(file_content);
   // Manipulate the Data

For some odd reason, Node-Webkit seems to be looking for the folder in a Temp Directory located in:

C:\\Users\\User\\AppData\\Local\\Temp\\nw9740_14956\\Configuration

The file is not there, and thus in the Console I get the following Error:

Uncaught Error: ENOENT: no such file or directory, open 'C:\\Users\\User\\AppData\\Local\\Temp\\nw9740_14956\\Configuration\\JSON.json'

I am running Windows (as you can tell), and I would like for fs to pull the file from the Folder (Configuration) that is adjacent to the app.exe.

Any help is appreciated

I've only done this once, so I may be wrong, but it looks like you're bundling your app content into the exe? If you do this, node-webkit will extract the app contents into the %TEMP% folder and then run the content from there.

Try checking the command line arguments to see if arg[0] will point you to the actual node-webkit exe that's running the app. From there, you should be able to construct a path to your configuration data.
