我正在实现一个类，该类使用对 Meta API 的请求来处理创建 Facebook 帖子。该过程分为两个阶段，分别针对图像和视频。按照文档，必须为每个图像或视频进行独立上传。随后，使用每个请求响应中返回的 ID，使用 attachment_media 和 {\'media_fbid\':\'image_id|video_id\'} 列表生成数据。当涉及到图像时，任务流程正常运行，没有任何问题。但是，当视频位于 attachment_media 列表中时，就会出现问题。有人知道以下错误的解决方案是什么吗？

我想在 React 中实现一个 SignalR 客户端。
我有一个提供 SignalR Hub 的 aspnet API。使用 C# SignalR 客户端，我可以连接集线器并发送+接收消息。因此，看来 SignalR 服务和 CORS 是正确的。
但是当我想要连接 React 时出现以下错误：
Debug: HubConnection failed to start successfully because of error 'Error: Unable to connect
to the server with any of the available transports.
WebSockets failed:
Error: 'WebSockets' is disabled by the client.
ServerSentEvents failed: Error: 'ServerSentEvents' is disabled by the client.
LongPolling failed: Error: 'LongPolling' is disabled by the client.'.
我的反应代码：
import { HubConnectionBuilder,LogLevel,HttpTransportType } from '@microsoft/signalr';
import { getUserAccessToken } from '../auth/UserManager';
export function ConnectToSignalR(){
return new HubConnectionBuilder()
.withUrl('http://localhost:18198/messagehub',options=> {
options.skipNegotiation=false;
options.transport = HttpTransportType.WebSockets;
options.accessTokenFactory = ()=>getUserAccessToken();
return options;})
.withAutomaticReconnect()
.configureLogging(LogLevel.Trace)
.build();
}
export function startSignalRConnection(signalRConnection){
if (signalRConnection) {
signalRConnection.start()
.then(result => {
console.log('SingnalR','Connected!');
signalRConnection.on('TimeWarningMessage', message => {
console.log(message);
});
})
.catch(e => console.log('SingalR Connection failed: ', e));
}
}
应用程序启动后，通过 useEffect 钩子在 React 应用程序的 App.js（主要组件）中调用代码。
“被客户端禁用”是什么意思？有没有办法禁用这些东西？我测试的浏览器是 Edge 和 Chrome 的最新版本，两者都有同样的问题。React 包的版本是 8.0.7，在 asp net core 端的后端，我使用的是 NET8
