如何将标记img src转换为外部存储ASP net Core2中的url？

private readonly IWebHostEnvironment _env;

public YourController(IWebHostEnvironment env)
{
    _env = env;
}

<img src="@Url.Content("~/path/to/image.jpg")" alt="Image">

using COSXML;
using COSXML.Auth;
using COSXML.Model.Object;

// 创建COSXML客户端
var config = new CosXmlConfig.Builder()
    .SetRegion("your-region") // 设置存储桶所在的地域
    .SetDebugLog(true) // 是否开启调试日志
    .Build();

var cosXml = new CosXmlServer(config, new DefaultQCloudCredentialProvider("your-secret-id", "your-secret-key"));

// 上传图片
var request = new PutObjectRequest("your-bucket", "path/to/image.jpg", "local/path/to/image.jpg");
var result = cosXml.PutObject(request);

// 获取图片URL
var url = cosXml.GenerateSignURL("your-bucket", "path/to/image.jpg", 3600); // 生成一个1小时有效期的URL
