创建Picasa相册并使用PHP和cURL将图像上传到它

我发现创建Picasa相册和上传图片的所有教程都使用了我尚未研究的Zend Framework.

可以使用PHP和cURL上传图片并创建相册吗？

我的图像存储在目录e：/ images中,图像信息存储在MysqL表中,如下所示：

SET sql_MODE="NO_AUTO_VALUE_ON_ZERO";
CREATE TABLE IF NOT EXISTS `picasaimage` (
  `id` bigint(1) unsigned NOT NULL AUTO_INCREMENT,`title` varchar(255) COLLATE utf8_unicode_ci NOT NULL,`content` varchar(255) COLLATE utf8_unicode_ci NOT NULL,`tags` varchar(255) COLLATE utf8_unicode_ci NOT NULL,`license` varchar(50) COLLATE utf8_unicode_ci NOT NULL,`image_path` varchar(150) COLLATE utf8_unicode_ci NOT NULL,`width` int(4) COLLATE utf8_unicode_ci NOT NULL,`height` int(4) COLLATE utf8_unicode_ci NOT NULL,PRIMARY KEY (`id`),) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=0 ;

我使用以下代码获取Google客户端身份验证码：

<?PHP  
$ch = curl_init();  

curl_setopt($ch,CURLOPT_URL,"https://www.google.com/accounts/ClientLogin");  
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);  

$data = array('accountType' => 'GOOGLE','Email' => 'youremailaddress@gmail.com','Passwd' => 'yourpassword','source'=>'PHI-cUrl-Example','service'=>'lh2');  

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);  
curl_setopt($ch,CURLOPT_POST,true);  
curl_setopt($ch,CURLOPT_RETURNTRANSFER,CURLOPT_POSTFIELDS,$data);  

$hasil = curl_exec($ch);  

echo $hasil;  
//SID=DQA...oUE  
//LSID=DQA...bbo  
//Auth=DQA...Sxq  
?>

任何人都可以为创建一个名为test并将图像上传的专辑提供一些指导？

EDIT1：

当我用PHP脚本上传照片时如何添加照片许可？

参考http://commons.wikimedia.org/wiki/Commons:Picasa_Web_Albums_files

检查从api获取相册照片的响应数据,应该有这样的东西：

"gphoto$license":{
           "$t":"ATTRIBUTION_NON_COMMERCIAL_NO_DERIVATIVES","id":3,"name":"Attribution-Noncommercial-No Derivative","url":"http://creativecommons.org/licenses/by-nc-nd/3.0"
        },

以下是创建相册的一些代码.我们将接收cURL呼叫进行身份验证.

//This is the cURL call to authenticate. We'll splitting out the return values 
//to more easily get the auth code.
$ret = explode("\n",curl_exec($ch));  

//Save all of the return values to an array so we can get them more easily later
$gvals = array();
foreach($ret as $item) {
    $flds = explode("=",$item);

    if(count($flds) > 1) {
        $gvals[$flds[0]] = $flds[1]; 
    }
}

//This is the authentication header we'll need to pass with each successive call
$authHeader = 'Authorization:  GoogleLogin auth="' . $gvals['Auth'] . '"';
$userId = "THE PICASA USER ID GOES HERE";
$FeedUrl = "https://picasaweb.google.com/data/Feed/api/user/$userId";

//This is the XML for creating a new album.
$rawXml = "<entry xmlns='http://www.w3.org/2005/Atom'
                xmlns:media='http://search.yahoo.com/mRSS/'
                xmlns:gphoto='http://schemas.google.com/photos/2007'>
              <title type='text'>Test album from PHP</title>
              <summary type='text'>This is a test album</summary>
              <gphoto:location>Louisville</gphoto:location>
              <gphoto:access>public</gphoto:access>
              <gphoto:timestamp>1152255600000</gphoto:timestamp>
              <category scheme='http://schemas.google.com/g/2005#kind'
                term='http://schemas.google.com/photos/2007#album'></category>
            </entry>";

//Setup our cURL options
//Notice the last one where we pass in the authentication header
$options = array(
            CURLOPT_URL=> $FeedUrl,CURLOPT_SSL_VERIFYPEER=> false,CURLOPT_POST=> true,CURLOPT_RETURNTRANSFER=> true,CURLOPT_HEADER=> true,CURLOPT_FOLLOWLOCATION=> true,CURLOPT_POSTFIELDS=> $rawXml,CURLOPT_HTTPHEADER=> array('GData-Version:  2',$authHeader,'Content-Type:  application/atom+xml')
        );
curl_setopt_array($ch,$options);

//This call will create the Picasa album.
//The return value is XML with a bunch of information about the newly created album.
$ret = curl_exec($ch);

上传照片的工作方式类似：

http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_protocol.html#PostPhotos

以下是无需元数据上传图片的功能代码：

$userId = "USER ID GOES HERE";
$albumId = "ALBUM ID GOES HERE";
$albumUrl = "https://picasaweb.google.com/data/Feed/api/user/$userId/albumid/$albumId";
$imgName = $_SERVER['DOCUMENT_ROOT'] . '/picasa/cute_baby_kitten.jpg';

//Get the binary image data
$fileSize = filesize($imgName);
$fh = fopen($imgName,'rb');
$imgData = fread($fh,$fileSize);
fclose($fh);

$header = array('GData-Version:  2','Content-Type: image/jpeg','Content-Length: ' . $fileSize,'Slug: cute_baby_kitten.jpg');
$data = $imgData; //Make sure the image data is NOT Base64 encoded otherwise the upload will fail with a "Not an image" error

$ret = "";
$ch  = curl_init($albumUrl);
$options = array(
        CURLOPT_SSL_VERIFYPEER=> false,CURLOPT_POSTFIELDS=> $data,CURLOPT_HTTPHEADER=> $header
    );
curl_setopt_array($ch,$options);
$ret = curl_exec($ch);
curl_close($ch);

以下是使用元数据上传照片的一个例子(最后！)：

$albumUrl = "https://picasaweb.google.com/data/Feed/api/user/$userId/albumid/$albumId";
$imgName = $_SERVER['DOCUMENT_ROOT'] . '/picasa/cute_baby_kitten.jpg';

$rawImgXml = '<entry xmlns="http://www.w3.org/2005/Atom">
              <title>plz-to-love-realcat.jpg</title>
              <summary>Real cat wants attention too.</summary>
              <category scheme="http://schemas.google.com/g/2005#kind"
                term="http://schemas.google.com/photos/2007#photo"/>
            </entry>';

$fileSize = filesize($imgName);
$fh = fopen($imgName,$fileSize);
fclose($fh);

$dataLength = strlen($rawImgXml) + $fileSize;
$data = "";
$data .= "\nMedia multipart posting\n";
$data .= "--P4CpLdIHZpYqNn7\n";
$data .= "Content-Type: application/atom+xml\n\n";
$data .= $rawImgXml . "\n";
$data .= "--P4CpLdIHZpYqNn7\n";
$data .= "Content-Type: image/jpeg\n\n";
$data .= $imgData . "\n";
$data .= "--P4CpLdIHZpYqNn7--";

$header = array('GData-Version:  2','Content-Type: multipart/related; boundary=P4CpLdIHZpYqNn7;','Content-Length: ' . strlen($data),'MIME-version: 1.0');

$ret = "";
$ch  = curl_init($albumUrl);
$options = array(
        CURLOPT_SSL_VERIFYPEER=> false,$options);
$ret = curl_exec($ch);
curl_close($ch);
