以PHP格式從Google雲端存儲中上載和檢索圖片

Question

我對這一切都很新穎。我正嘗試從iPhone應用中上傳圖片，並使用PHP將其存儲到我的Google Cloud Storage存儲桶（gs：// app/users/profile_pics /）中。我可以使用本地文件系統執行此操作，但它不適用於Google雲端存儲。

**iOS Code (this works)** 
... 
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:profile_pic_data]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
... 

**PHP Code to local file system (works using local file system)** 
if($_POST) { 
... 
    //Make user directory to house files 
    $upload_dir = 'user_data/' . $user_id . '/'; 
    $path = mkdir("$upload_dir", 0777); 

    //Save file to newly created folder 
    $file = 'profile_pic.jpg'; 
    $profile_pic_path = $upload_dir . $file; 
    if (move_uploaded_file($_FILES['file']['tmp_name'], $profile_pic_path)) { 
     //Profile pic uploaded, Update profile pic field in database 
     $query = "UPDATE users SET profile_image_path='$upload_path' WHERE email='$user_email'"; 
     if(mysql_query($query)){ 
      echo json_encode(array('success' => 1,'info_message' => "")); // Account fully created! 
     } 
... 

**PHP using Google Cloud Storage (not working, trying the most simple version first)** 
... 
if($_POST) { 
... 
    $gs_name = $_FILES['file']['tmp_name']; 
    move_uploaded_file($gs_name, 'gs://socalityapp/users/profile_pics/profile_pic.jpg'); 
... 

我似乎無法得到它存儲。我知道我的其他PHP正在工作，因爲我正在將配置文件保存到我的Google Cloud SQL數據庫中。

幫助或批評（iOS，PHP等）將非常感激！

雲存儲與appengine不在同一臺機器上。你永遠無法在appengine上使用本地文件系統。

當您通過表單提交收到帖子時，您需要將圖像數據向前傳遞到存儲。我看不到一個PHP示例，但可以引用JSON API與存儲進行交互。你應該能夠使用Buzz做simple upload
