我们在ReactJS中有一个工作应用程序,其中有一部分是不同用户之间的真实的聊天。在reactJs中,我们使用@microsoft/signalR,一切正常。这是代码块:
useEffect(() => {
const ConnectionId = "e48950002479" // user.token;
const newConnection = new HubConnectionBuilder()
.withUrl('https://none_of_your_business/chatHub', {
accessTokenFactory: () => ConnectionId
}) //replace with the URL of your SignalR hub
.configureLogging(LogLevel.Debug)
.build();
setConnection(newConnection);
}, [])
useEffect(() => {
if (connection) {
connection
.start()
.then(() => {
console.log("SignalR Connected!");
connection.on("ReceiveMessage", (message) => {
console.log("Received message:", message);
});
})
.catch((error) => console.log(`SignalR Connection error: ${error}`));
}
}, [connection]);
const sendMessage = async () => {
await connection.invoke('SendMessage', "1626659a57c6", "Heyo", "1626659a57c6");
};
然而,当我为react-native复制相同的代码时(使用相同的库),它并没有发送ConnectionId变量。这真的很奇怪,因为它在reactJS中工作得很完美,但在react-native中却没有。有什么提示吗?
