Back then, when we were still a course work student.....the printing quota was around 1K every semester......we`ve already thought that was a lot....

however...after been a research assistance........what the hell.........unbelieveable...
10G internet quota....100K black and whit printing quota and 200 colour printing quota.....

man....now..i felt a little bit regret...i should ask for a research master instead of course work at the very beginning...

damn it...howcome there are so much different.....we pay for exact the same amount of tuition fee...

ah~~~~~~~~~~~~~~~~ look at the place the read arrow is pointing.....

it should be some image AD...however.....MSN failed to parse it....must be the wrong script send from Microsoft.....

-----------------------------------------------------------------------------------------------------------------------

Ok...i have to go back to study......fighting for my last exam....

来澳洲上学快两年了，花了四万多澳币交学费，
没想到最后毕业了，居然有机会赚回学校一笔，
在这里感谢一下我们的 Professor Anna... 拉了个项目，两个多月就能要回10K的学费。。哈哈

想当年出国前，给吉大的教授干了一年半，也只是跟着别人后面发了几篇文章。

唉。。。还是钱好啊。。。。

毕业的晚会。。。全班的cosplay。。。最多的掌声。。。还有最多的欢呼。。。

很快。。。我又要毕业了。。。。

Microsoft is not that friendly to other language`s programer...
it is hard to find out resource how to access Azure storage in anohter language besides C#

This article is show how to access Azure Blob Storage in java, although Steve Marx has already post a artiles on his blog months ago,
but it is still hard to use for beginner.

What i am going to do in this article is that:
i have already got an container call "cantainer" under my account, i am going to put a blob call "abc" into the container.

Let`s begin:
Azure Storage is a REST base database, so i choose to use httpclient from apache, it is not a must that u have to use the same lib as mine...
       <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.0-beta2</version>
        </dependency>


the hard thing when comunicate with azure storage is that, we have to sign our request for authorization

There is a article from microsoft : http://msdn.microsoft.com/en-us/library/dd179428.aspx
list what we should do to sign the request,
e.g blob storage :

StringToSign = VERB + "\n" +
               Content-MD5 + "\n" +    //(optional)
               Content-Type + "\n" +
               Date + "\n" +
               CanonicalizedHeaders + 
               CanonicalizedResource;

In Java :

    public static String ContentType = "Content-Type";
    public static String X_MS_Date = "x-ms-date";

    public static synchronized void Sign(HttpRequestBase request, String account, String key) throws Exception {
        SimpleDateFormat fmt = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss");
        fmt.setTimeZone(TimeZone.getTimeZone("GMT"));
        request.setHeader(X_MS_Date, fmt.format(Calendar.getInstance().getTime()) + " GMT");

        StringBuilder sb = new StringBuilder();
        sb.append(request.getMethod().toUpperCase() + "\n\n");
        sb.append(request.getFirstHeader(ContentType).getValue() + "\n\n");
        sb.append(X_MS_Date + ":" + request.getFirstHeader("x-ms-date").getValue() + "\n");
        sb.append("/" + account + request.getURI().getPath());

        Mac mac = Mac.getInstance("HmacSHA256");
        mac.init(new SecretKeySpec(Base64Coder.decode(key), "HmacSHA256"));
        String finalKey = new String(Base64Coder.encode(mac.doFinal(sb.toString().getBytes("UTF-8"))));
        request.setHeader("Authorization", "SharedKey " + account + ":" + finalKey);
    }

HOWTO use it:

public static void main(String args[]) throws Exception {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPut put = new HttpPut("http://" + YOUR_ACCOUNT + ".blob.core.windows.net/container/abc");
        put.addHeader(PutBlob.ContentType, "text/plain");   // by default is binary, you should specify a qualify MINE TYPE
        put.setEntity(new StringEntity("Hello world!!", "UTF-8"));
        Sign(put, YOUR_ACCOUNT, YOUR_KEY);

        log.debug(EntityUtils.toString(httpclient.execute(put).getEntity()));
    }
