Question

我正在尝试将文件上传到Azure Blob存储。出于某种原因，当我尝试在存储中放入新的块blob时，它告诉我资源不存在。我确信这是我想念的傻事。

根据文件：

Put Blob操作会创建新的块blob或页blob，或更新现有块blob的内容。更新现有块blob会覆盖blob上的所有现有元数据。 Put Blob不支持部分更新;现有blob的内容将被新blob的内容覆盖。要执行块blob内容的部分更新，请使用Put Block List（REST API）操作。

CORS已经设置好了。

当我做预检并得到这个时：

但是当我发出PUT请求时，这些就是结果。

您的请求必须经过身份验证才能上传blob。有关将共享访问签名与CORS一起使用的详细信息，请参阅我们的Windows Azure Storage: Introducing CORS博文。

Azure Rest API PUT Block Blob返回“指定的资源不存在”。 CORS
