Example

var UPYUN = require('upyun');

var upyun = new UPYUN('testbucket', 'operatername', 'md5(operaterpwd)', 'ctcc', 'legacy');

upyun.getUsage(function(err, result) {
    //...
})

Response

In this SDK, every api will return a response in the format:

Normal

{
    statusCode: 200,    // http stats code
    headers: {
        server: 'nginx/1.1.19',
        date: 'Wed, 13 Aug 2014 02:15:27 GMT',
        'content-type': 'application/json',
        'content-length': '24',
        connection: 'close'
    },                  // response header
    data: {
        space: 2501,
        files: 1
    }                   // response body
}

Error catch

When an error occured, the error will be catched, and returned in the response

{
    statusCode: 401,    // http stats code
    error: {
        error_code: 40104,
        request: 'GET /imgtest',
        message: 'Signature error, (signature = md5(METHOD&PATH&DATE&CONTENT_LENGTH&MD5(PASSWORD))).'
    },                  // error message
    headers: {
        server: 'nginx/1.1.19',
        date: 'Wed, 13 Aug 2014 02:19:07 GMT',
        'content-type': 'application/json',
        'content-length': '145',
        connection: 'close',
        'www-authenticate': 'Basic realm="UpYun"'
    }                   // response header
}

The different between these two responses is the error and body.

All responses contain http status code and raw response header for futher usage.
