React Native 31,新 Appdelegate.m 没有要更改的本地主机:网络请求失败 [英] React Native 31, New Appdelegate.m no localhost to change : Network Request Failed
问题描述
我刚刚升级到 react-native 的最新版本 (31),我正在运行的应用程序不再运行了.每次我从 fetch 中收到 Network Request Failed 错误.
I just upgraded to latest version (31) of react-native, my app which was working, is not working anymore. everytime i get Network Request Failed error from fetch.
AppDelegate.m 已更改且没有 localhost 或 127.0.0.1 可更改.
AppDelegate.m is changed and there is no localhost or 127.0.0.1 to change.
它是否放在其他地方?
AppDelegate.m :
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
或者我应该更改 RCTWebSocketExecutor.m 吗?
or should i change 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;
}
推荐答案
我找到了解决方案.允许任意加载"以某种方式从 info.plist 中删除.它应该被添加到 info.plist 并且值应该是YES",否则应用程序无法访问互联网.
I found the solution. "Allow Arbitrary Loads" was removed from info.plist somehow. it should be added to info.plist and value should be "YES" otherwise app cannot access internet.
