ImageSharp.Web AzureBlobStorageImageProvider 给出 404

Question

按照示例代码，我尝试连接 ImageSharp.Web 的 AzureBlobStorageImageProvider，但所有图像请求都会导致 404。知道我的接线遗漏了什么吗？

查看文档似乎 url 惯例应该是 https://localhost:44336/container-name/file-name.jpg?width=30

在我的 Startup.cs 中，我有以下代码：

public void ConfigureServices(IServiceCollection services)
{
    ...

    services.AddImageSharp()
        .Configure<AzureBlobStorageImageProviderOptions>(options =>
        {
            // The "BlobContainers" collection allows registration of multiple containers.
            options.BlobContainers.Add(new AzureBlobContainerClientOptions
            {
                ConnectionString = "REDACTED",
                ContainerName = "test-container"
            });
        })
        .AddProvider<AzureBlobStorageImageProvider>()
        .Configure<AzureBlobStorageCacheOptions>(options =>
        {
            options.ConnectionString = "REDACTED";
            options.ContainerName = "cache";

            // Optionally create the cache container on startup if not already created.
            AzureBlobStorageCache.CreateIfNotExists(options, PublicAccessType.None);
        })
        .SetCache<AzureBlobStorageCache>();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    ...

    app.UseImageSharp();
}

有什么我可能遗漏的想法吗？

看来您需要先 ClearProviders() 添加 AzureBlobStorageImageProvider。所以代码变成：

.ClearProviders()
.AddProvider<AzureBlobStorageImageProvider>()
