Shell脚本作为默认浏览器

我找不到任何已经存在的选项（但仍有可能存在），所以我最终写了一个。基本上，它的作用是告诉系统该应用程序是浏览器，最终将其自身设置为默认浏览器（请参阅参考资料#define SET_AS_DEFAULT_BROWSER），并在接收到正确的事件时最终通过将url发送到my_link_opener位于应用程序包中的脚本来管理url （即是在.app目录中）。bash命令称为：

nohup /path/to/my_link_opener "_an_url_" >& /dev/null &

#import "ZFTAppDelegate.h"

NSString *runCommand(NSString *commandToRun)
{
    NSTask *task;
    task = [[NSTask alloc] init];
    [task setLaunchPath: @"/bin/sh"];

    NSArray *arguments = @[@"-c" ,[NSString stringWithFormat:@"%@", commandToRun]];
    [task setArguments: arguments];

    NSPipe *pipe;
    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];

    NSFileHandle *file;
    file = [pipe fileHandleForReading];

    [task launch];

    NSData *data;
    data = [file readDataToEndOfFile];

    NSString *output;
    output = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
    return output;
}

#define SET_AS_DEFAULT_BROWSER

@implementation ZFTAppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    NSAppleEventManager *em = [NSAppleEventManager sharedAppleEventManager];
    [em setEventHandler:self
            andSelector:@selector(getUrl:withReplyEvent:)
          forEventClass:kInternetEventClass
             andEventID:kAEGetURL];
    [em setEventHandler:self
            andSelector:@selector(getUrl:withReplyEvent:)
          forEventClass:'WWW!'
             andEventID:'OURL'];


#ifdef SET_AS_DEFAULT_BROWSER
    CFStringRef bundleID = (__bridge CFStringRef)[[NSBundle mainBundle] bundleIdentifier];
    LSSetDefaultHandlerForURLScheme(CFSTR("http"), bundleID);
    LSSetDefaultHandlerForURLScheme(CFSTR("https"), bundleID);
#endif


}

- (void)getUrl:(NSAppleEventDescriptor *)event withReplyEvent:(NSAppleEventDescriptor *)replyEvent
{
    NSString *url = [[event paramDescriptorForKeyword:keyDirectObject] stringValue];
    NSString* scriptPath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"my_link_opener"];
    runCommand([NSString stringWithFormat:@"nohup %@ \"%@\" >& /dev/null &", scriptPath, url]);
}

@end

请记住，您应该在应用程序的info.plist中拥有此功能（需要通知操作系统有关您的应用程序处理http / s url的功能）：

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>https</string>
        </array>
        <key>CFBundleURLName</key>
        <string>Secure http URL</string>
    </dict>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>http</string>
        </array>
        <key>CFBundleURLName</key>
        <string>http URL</string>
    </dict>
</array>
