React Native 31，New Appdelegate.m no localhost to change：networking请求失败

我刚刚升级到react-native的最新版本（31），我的应用程序正在工作，不再工作了。 每次我得到networking请求失败错误从提取。

AppDelegate.m被更改，没有本地主机或127.0.0.1更改。

它放在别的地方吗？

AppDelegate.m：

#import "AppDelegate.h" #import "RCTBundleURLProvider.h" #import "RCTRootView.h" @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSURL *jsCodeLocation; jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil]; RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation moduleName:@"OpenCampus" initialProperties:nil launchOptions:launchOptions]; rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1]; self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; UIViewController *rootViewController = [UIViewController new]; rootViewController.view = rootView; self.window.rootViewController = rootViewController; [self.window makeKeyAndVisible]; return YES; } @end 

或者我应该改变RCTWebSocketExecutor.m？

 if (!_url) { NSUserDefaults *standardDefaults = [NSUserDefaults standardUserDefaults]; NSInteger port = [standardDefaults integerForKey:@"websocket-executor-port"] ?: 8081; NSString *host = [[_bridge bundleURL] host]; if (!host) { host = @"localhost"; } NSString *URLString = [NSString stringWithFormat:@"http://%@:%zd/debugger-proxy?role=client", host, port]; _url = [RCTConvert NSURL:URLString]; } _jsQueue = dispatch_queue_create("com.facebook.react.WebSocketExecutor", DISPATCH_QUEUE_SERIAL); _socket = [[RCTSRWebSocket alloc] initWithURL:_url]; _socket.delegate = self; _callbacks = [NSMutableDictionary new]; _injectedObjects = [NSMutableDictionary new]; [_socket setDelegateDispatchQueue:_jsQueue]; NSURL *startDevToolsURL = [NSURL URLWithString:@"/launch-js-devtools" relativeToURL:_url]; [NSURLConnection connectionWithRequest:[NSURLRequest requestWithURL:startDevToolsURL] delegate:nil]; if (![self connectToProxy]) { RCTLogError(@"Connection to %@ 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`.", _url); [self invalidate]; return; }

我find了解决scheme。 “允许任意负载”以某种方式从info.plist中删除。 它应该被添加到info.plist和值应该是“是”否则应用程序无法访问互联网。
