简单的PHP cURL文件上传到Azure存储blob

Question

我有问题来创建一个新的/简单的PHP脚本/函数与cURL上传简单文件（image.jpg）从本地服务器到Azure存储 - 使用共享密钥身份验证的blob容器。我不希望（由于其他原因）使用SDK和/或多个文件/库。我只需要一个函数 - fileUpload - 就是这样。

文档没有提供用文件覆盖上传（POST）的完整示例。 https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/authentication-for-the-azure-storage-services

目前还不清楚什么是必需的标题，以及对签名/认证属性需要哪些标题。 （多MSDN网站有不同的标题，例如 - https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/put-blob

是否有人对这个简单的例子，就是想分享

<?php 
error_reporting(E_ALL); 
ini_set('display_errors', 'On'); 
date_default_timezone_set('UTC'); 

$destinationURL = 'https://mystorage.blob.core.windows.net/blob1/image.jpg'; 
$accesskey = "qJXTMmw2Esal8/tXgfWk0RLwMNJ6OQKEt0E8EMZ8VhQrzGi5uqJqeKvi1l7iqnOddp7bdtai5rPpC6ynHttl1w=="; 
$storageAccount = 'mystorage'; 
$filetoUpload = realpath('./image.jpg'); 

function upload($filetoUpload, $storageAccount,$destinationURL,$accesskey) { 
    $currentDate = date("D, d M Y H:i:s"); 

    $postFields = array(
     'extra_info' => '123456', 
     'file_contents'=>'@'.$filetoUpload 
    ); 

    $headerText="" 
     ."x-ms-version: 2015-02-21\n" 
     ."x-ms-date:" .$currentDate." GMT\n" 
     ."Content-Type: text/plain; charset=UTF-8\n" 
     ."x-ms-blob-content-disposition: attachment; filename=".$filetoUpload."\n" 
     ."x-ms-blob-type: BlockBlob\n" 
     ."x-ms-meta-m1: v1\n" 
     ."x-ms-meta-m2: v2\n" 
     ; 

    $hash = hash_hmac('sha256', $headerText, base64_decode($accesskey), true); 
    $sig = base64_encode($hash); 

    $headerText.="Authorization: SharedKey ".$storageAccount.":".$sig."\n"; 
    $headerText.="Content-Length: 280"; 
    $headers = explode("\n", $headerText); 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); 
    curl_setopt($ch, CURLOPT_URL, $destinationURL); 
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
    $result = curl_exec($ch); 
    echo ('Result<br/>'); 
    print_r($result); 
    echo ('Error<br/>'); 
    print_r(curl_error($ch)); 
    curl_close ($ch); 
return; 
} 

upload($filetoUpload, $storageAccount,$destinationURL,$accesskey);

你可以试试下面的代码片段
