昨天我刚刚在Blazor 3.1应用中解决了这个问题！我选择使用JS Interop，这非常容易.

I just solved this in a Blazor 3.1 app yesterday! I opted to use JS Interop and it was super easy.

我的Web应用程序具有多个前端，包括MVC，Razor Pages和Blazor，因此您可以打开主解决方案文件，然后检出Blazor项目:

My web app has multiple front ends, including MVC, Razor Pages and Blazor, so you can open the main solution file and then check out the Blazor project:

Blazor项目中的注意事项；

Things to note in the Blazor project;

• 我将局部视图实现为剃刀组件
• 在共享"文件夹中查找/_CookieConsentPartial.razor

• MainLayout.razor使用此剃须刀组件

• I implemented the partial view as a razor component
• look for /_CookieConsentPartial.razor in the Shared folder

• MainLayout.razor uses this razor component

_Host.cshtml文件包括我的js互操作文件

The _Host.cshtml file includes my js interop file

js Interop文件包含document.cookie用法

the js Interop file contains the document.cookie usage

剃刀组件使用JSRuntime.InvokeVoidAsync调用JS方法以接受GDPR同意消息并存储cookie

the razor component uses JSRuntime.InvokeVoidAsync to call the JS method to accept the GDPR consent message and store the cookie

希望有帮助！
