[warn][tid:com.facebook.React.WebSocketExecutor][RCTWebSocketExecutor.m:128] WebSocket connection failed with error Error Domain=NSPOSIXErrorDomain Code=61 "Connection refused"
[warn][tid:com.facebook.react.RCTBridgeQueue][RCTWebSocketExecutor.m:71] Connection to http://localhost:8081/debugger-proxy timed out. Are you running node proxy? If you are running on the device, check if you have the right IP address in `RCTWebSocketExecutor.m`.
[error][tid:main] socket closed
[error][tid:com.facebook.React.WebSocketExecutor] socket closed
解決:
在RCTWebSocketExecutor.m文件中修改setup函數(shù)中的localhost為你電腦的IP地址(例如:192.168.0.104)
修改前代碼:
- (void)setUp
{
if (!_url) {
NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
NSInteger port = [standardDefaults integerForKey:@"websocket-executor-port"] ?: 8081;
NSString *URLString = [NSString stringWithFormat:@"http://localhost:%zd/debugger-proxy", port];
_url = [RCTConvert NSURL:URLString];
}
// 此處省略后面代碼
}
修改后代碼:
- (void)setUp
{
if (!_url) {
NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults];
NSInteger port = [standardDefaults integerForKey:@"websocket-executor-port"] ?: 8081;
NSString *URLString = [NSString stringWithFormat:@"http://192.168.0.104:%zd/debugger-proxy", port];
_url = [RCTConvert NSURL:URLString];
}
// 此處省略后面代碼
}
題外話:在終端檢測Node.js所啟動服務(wù)的端口是否為默認的8081
