利用 Flickr API 取得原始圖片網址

更新於 2017-05-19 18:53:20

鑒於網站上的空間有限,存放圖片又非常不方便,存本站會耗費空間與流量,存外站就不會。而 Flickr 支持 1 TB 的免費圖片空間!還支援原圖外連,這對我來說,非常好用!

為了把外站同步相簿到本站,需要研讀一下 Flickr API ,請參考:
https://www.flickr.com/services/api/

由於本教學是不需要"簽發授權的",所以原圖只能是上傳者公開,才能取得,否則只能其他解析度的圖片。但拿不到原圖,基本上還是很高清的。

不然只能用Flickr的OAuth取得Token,不過太麻煩我就不講了。可以參考:
https://www.flickr.com/services/api/explore/flickr.photosets.getPhotos

必須要自己設定成公開,API才可以取得原始圖片。

第一步、要先建立應用程式,https://www.flickr.com/services/apps/create/apply/

隨便填一下資料後,可以取得 應用程式的 key 值與金鑰。

然後使用:http://idgettr.com/

輸入自己個人頁面網址,可以取得 自己的 User ID,長得像是: 123456789@N01。

接著用「程式」訪問 Flickr 的 API 特殊網址 (要記得變更網址 { } 大括號夾住部分):

API_KEY,USER_ID 請照上述步驟取得
https://api.flickr.com/services/rest/?method=flickr.photosets.getList&api_key={API_KEY}&user_id={USER_ID}&format=json

可以得到如下圖的頁面:這是JSON格式的資料。請尋找您要取得網址的相簿ID。(長得像是下圖橘色所示)

然後再用程式訪問

{API_KEY},{USER_ID},{PHOTOSET_ID}記得替換
https://api.flickr.com/services/rest/?method=flickr.photosets.getPhotos&api_key={API_KEY}&user_id={USER_ID}&photoset_id={PHOTOSET_ID}&extras=url_o&format=json

就可取得 原始 資料。

範例程式碼:

<textarea name="contents" id="contents" style="resize:vertical;height:150px;font-size:12pt;"></textarea>
<script type="text/javascript">
var http = new XMLHttpRequest("Microsoft.XMLHTTP");
var url_='https://api.flickr.com/services/rest/?method=flickr.photosets.getPhotos&api_key={API_KEY}&user_id={USER_ID}&photoset_id={PHOTOSET_ID}&extras=url_o&format=json';
function connect(){
	http.onreadystatechange = function(){
		if (http.readyState==4){
			if (http.status==200){
				var str = http.responseText.toString();
				str = str.substring(14,str.length-1);
				var obj = JSON.parse(str);
				var html_code_to_load = "";
				for (var i=0;i<obj['photoset']['photo'].length;i++){
					html_code_to_load += obj['photoset']['photo'][i]['url_o'] + "\n";
				}
				document.getElementById('contents').innerHTML=html_code_to_load.substring(0,html_code_to_load.length-1);
			}else{
				//Connect Failed.
			}
		}
	}
	http.open("GET",url_,true);
	http.send();
}
connect();
</script>

PHP string to html characters 字串轉HTML碼

更新於 2016-01-11 20:09:41

緣由:

最近因為裝了PHP7的緣故,又加上有一點點的閒,故研究PHP這塊。尤其是運算耗時方面,因為我本身就是要測試PHP7可以快到何種地步。聽說是快20倍的樣子。

結果,到最後我反而開始寫程式碼,昨天修正BBcode檢查的函數,運行約一萬字的代碼,結果速度慢到極致,被我修改後,倒加速不少,總速度提升82倍,原本12.3秒,修正到0.15秒(如果僅比較檢查BBcode的函數,加快上萬倍。),後來遇上了這個轉HTMLcode的問題,原先寫得太慢了,這是我第三次修正!

//目前我寫的最快的版本。

function string_to_utf16_ascii_HTML_new2($str){
	$str=mb_convert_encoding($str, 'ucs-2', 'utf-8');
	for($i=0;$i<strlen($str);$i+=2){
		$str2.='&#'.str_pad((ord($str[$i])*256+ord($str[$i+1])),5,'0',STR_PAD_LEFT).';';
	}
	return $str2;
}

//稍慢的版本(舊版)

function string_to_utf16_ascii_HTML_new($str){
	for ($i=0;$i<strlen($str);$i++){
		$k=ord($str[$i]);
		if ($k >= 192 and $k <= 223){
			$k=$k-192;
			$k2=ord($str[$i+1])-128;
			$c=$c.'&#'.str_pad($k*64+$k2,5,'0',STR_PAD_LEFT).';';
		}elseif ($k >= 224 and $k <= 239){
			$k=$k-224;
			$k2=ord($str[$i+1])-128;
			$k3=ord($str[$i+2])-128;
			$c=$c.'&#'.str_pad($k*4096+$k2*64+$k3,5,'0',STR_PAD_LEFT).';';
		}elseif ($k >= 128 and $k <= 191){
		}else{
			$c=$c.'&#'.str_pad($k,5,'0',STR_PAD_LEFT).';';
		}
	}
	return $c;
}

//極慢的版本(初版)

function string_to_utf16_ascii_HTML($str){
	for ($i=0;$str[$i]!="";$i++){
		$b[]=ord($str[$i]);
	}
	$str2=',';
	for ($i=0;$str[$i]!="";$i++){
		$xa=str_pad(decbin($b[$i]),8,'0',STR_PAD_LEFT);
		if (substr($xa,0,3) == "110"){
			$xb=str_pad(decbin($b[$i+1]),8,'0',STR_PAD_LEFT);
			$xx1=substr($xa,3);
			$xx2=substr($xb,2);
			$c=$c.$str2.str_pad(bindec($xx1.$xx2),5,'0',STR_PAD_LEFT);
		}elseif (substr($xa,0,4) == "1110"){
			$xb=str_pad(decbin($b[$i+1]),8,'0',STR_PAD_LEFT);
			$xc=str_pad(decbin($b[$i+2]),8,'0',STR_PAD_LEFT);
			$xx1=substr($xa,3);
			$xx2=substr($xb,2);
			$xx3=substr($xc,2);
			$c=$c.$str2.str_pad(bindec($xx1.$xx2.$xx3),5,'0',STR_PAD_LEFT);
		}elseif (substr($xa,0,2) == "10"){
		}else{
			$c=$c.$str2.str_pad($b[$i],5,'0',STR_PAD_LEFT);
		}
	}
	return substr($c,1);
}

//將HTMLcode轉回UTF-8字串。

function utf16_ascii_HTML_to_string($str){
	return mb_convert_encoding($str, 'UTF-8', 'HTML-ENTITIES'); 
}

/********

使用方法:

*********

$str='這是測試123';
$encode_str=string_to_utf16_ascii_HTML_new2($str);
echo $encode_str;

//output:
//&#36889;&#26159;&#28204;&#35430;&#00049;&#00050;&#00051;
//以瀏覽器顯示,等同於「這是測試123」。

echo utf16_ascii_HTML_to_string($encode_str);

//output:
//這是測試123

程式設計缺陷足以修改Header偽造IP

No Comments
-
更新於 2017-05-19 18:59:14

這其實是個老梗,很久以前就知道了。今天又突然想到,發篇文章好了。

很多網站上的程式教學都是錯誤的,取得IP方法用get Header 的 Client-IP 及 X-Forwarded-For

真的是禍害,Header是可以給用戶隨意變更的。

我修改了 Header 在網站上隨意搜尋 What is my ip ?。

結果大部分網站都有問題!

我怎麼改,網站就怎麼顯示,怎麼都對。如果今天我把Header改成<script>標籤,不就造成了XSS攻擊漏洞?改成SQL語法,造成SQL注入漏洞。

只是剛好想到,之前也沒發過類似的文章,補發。
