我在使用 cURL 创建一个新的/简单的 PHP 脚本/函数以将简单文件 (image.jpg) 从本地服务器上传到 Azure 存储时遇到问题 - 使用共享密钥身份验证的 blob 容器。我不想(出于其他原因)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
还不清楚需要哪些标头,以及签名/身份验证属性需要哪些标头。(例如,具有不同标头的多个 MSDN 站点 - https://docs.microsoft.com/en-us/rest/api/storageservices/fileservices/put-blob
有人想分享这个简单的例子吗?
