SMJobBless给出错误CFErrorDomainLaunchd Code = 8 [英] SMJobBless gives error CFErrorDomainLaunchd Code=8

问题描述

我正在尝试通过SMJobBless安装帮助程序工具，并且出现以下错误，

I am trying to install a helper tool via SMJobBless and I am getting the following error,

Error Domain = CFErrorDomainLaunchd代码= 8该操作无法完成.(CFErrorDomainLaunchd错误8.)

Error Domain=CFErrorDomainLaunchd Code=8 "The operation couldn’t be completed. (CFErrorDomainLaunchd error 8.)

我验证了代码符号，应用程序和帮助程序工具的清单，在launchServices中复制了该工具，并链接了plists.

I verified the code sign, plist of application and helper tool, copied the tool in launchServices and also linked the plists.

有人可以帮助我吗?

谢谢

推荐答案

验证以下内容:

1.Code

- (BOOL)blessHelperWithLabel:(NSString *)label
                       error:(NSError **)error {   

    BOOL result = NO;

    AuthorizationItem authItem      = { kSMRightBlessPrivilegedHelper, 0, NULL, 0 };
    AuthorizationRights authRights  = { 1, &authItem };
    AuthorizationFlags flags        =   kAuthorizationFlagDefaults              |
    kAuthorizationFlagInteractionAllowed    |
    kAuthorizationFlagPreAuthorize          |
    kAuthorizationFlagExtendRights;

    AuthorizationRef authRef = NULL;

    /* Obtain the right to install privileged helper tools (kSMRightBlessPrivilegedHelper). */
    OSStatus status = AuthorizationCreate(&authRights, kAuthorizationEmptyEnvironment, flags, &authRef);
    if (status != errAuthorizationSuccess) {
        NSLog(@"%@", [NSString stringWithFormat:@"Failed to create AuthorizationRef. Error code: %d", (int)status]);

    } else {
        /* This does all the work of verifying the helper tool against the application
         * and vice-versa. Once verification has passed, the embedded launchd.plist
         * is extracted and placed in /Library/LaunchDaemons and then loaded. The
         * executable is placed in /Library/PrivilegedHelperTools.
         */
        result = SMJobBless(kSMDomainSystemLaunchd, (CFStringRef)label, authRef, (CFErrorRef *)error);
    }
    return result;
}

2.info.plist(主应用程序)中安装后拥有的工具

2.Tools owned after installation field in info.plist(main app)

helper bundle : identifier <Helper Bundle Identifier> and certificate leaf[subject.CN] = "Developer ID Application: xxxxx (YYXSFDHZ6W)"

3.允许客户端添加和删除帮助程序info.plist中的工具字段.

3.Clients allowed to add and remove tool field in helper info.plist.

item 0 : identifier <Main App Bundle Identifier> and certificate leaf[subject.CN] = "Developer ID Application: xxxxxx (YYXSFDHZ6W)"

4.检查xxxxHelperTool-Launchd.plist中归档的MachServices.

4.Check MachServices filed in xxxxHelperTool-Launchd.plist.it should be

helper tool bundle : YES
