我正在尝试通过控制台应用程序与 Azure Blob 存储上的容器进行通信。我无法使用 SDK,因此 REST 是我唯一的选择。语言是 C#,带有 .NET 4.5.2。
我已经尝试过这两个代码并且都返回相同的错误
Azure Rest API 将 blob 放在 StackOverflow 上
Azure Blob 存储第 5 部分(非 StackOverflow)
The error that I receive is 400 Bad Request
还有其他人遇到过同样的问题并成功解决了吗?
我为几乎所有内容添加了带有 (*) 的 CORS 规则
该代码与两个链接完全相同,因此我不会在此处添加它。
