我正在尝试在 mvc 项目中创建一个动作。可以将文件和图像上传到我的天蓝色存储。但由于某种原因，它不会正确上传，这就是我的猜测。如果我使用“Azure Storage Explorere”上传图像，它可以正常工作。示例：http ://storage.sogaard.us/company1/wallpaper-396234.jpg 但是如果我尝试上传图片，虽然我的操作不起作用，它会发送 200 表示成功和正确的内容类型，但图片不会加载，我的开发人员工具告诉我我没有从服务器获得数据。示例：http ://storage.sogaard.us/company1/b9206edac188e1d8aa2b3be7cdc4b94a.jpg
我试图将上传的 til 保存到我的本地计算机而不是 azure 存储中，并且在那里运行良好！我根本找不到原因，这一直困扰着我一整天:(
这是我的代码
