Objective C 项目中的 Applescript

Question

我正在尝试在我的 mac 应用程序上通过 applescript 运行此 shell 脚本命令。它在 applescript 编辑器中工作正常，但是当我在 xcode 中运行它时，如下所示，它不起作用。我做错了吗？

NSString *asString = [[NSString alloc] initWithFormat:@"property MACaddr : \"gg:gg:gg:gg:gg:gg\"\n property WAN_IP_address : \"255.255.255.255\"\n property port_number : \"9\"\n "
                    "on run\n set command to \"/usr/bin/php -r \" & quoted form of (\"$mac = \" & quoted form of MACaddr & \"; $porttemp = \" & quoted form of port_number & \";$ip = \" & quoted form of WAN_IP_address & \"; \" & \"" 
                                        "$mac_bytes = explode(\\\":\\\", $mac); "
                                          " $mac_addr = \\\"\\\"; "
                                          " for ($i=0; $i<6; $i++) "
                                          " $mac_addr .= chr(hexdec($mac_bytes[$i]));" 
                                          " $packet = \\\"\\\"; "
                                          " for ($i=0; $i<6; $i++)   "
                                          " $packet .= chr(255); "
                                           "for ($i=0; $i<16; $i++)  "
                                           "$packet .= $mac_addr;" 
                                          " $port = $porttemp; "
                                           "$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);" 
                                           "socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, TRUE);" 
                                           "socket_sendto($sock, $packet, strlen($packet), 0, $ip, $port);" 
                                           "socket_close($sock);\") "
                                           "do shell script command \n"
                                            "end run"   ];
NSLog(@"the applescript %@", asString);
NSAppleScript *asScript = [[NSAppleScript alloc] initWithSource:asString];
[asScript executeAndReturnError:nil];
[asString release];
[asScript release];

这是在我的 Applescript 编辑器中运行良好的确切 applescript。我已经用正确的反斜杠编辑了上面的部分，并且它与我的 applescirpt 的工作原理相同。但是，它在 xcode 中仍然不起作用，并且魔术包没有被发送。 （使用wireshark来监控这一点。）任何想法出了什么问题？我什至添加了运行部分。

property MACaddr : "gg:gg:gg:g4:g5:gg"
property WAN_IP_address : "255.255.255.255"
property port_number : "9"

on run
    set command to "/usr/bin/php -r " & quoted form of ("$mac = " & quoted form of     MACaddr & "; $porttemp = " & quoted form of port_number & ";$ip = " & quoted form of WAN_IP_address & "; " & " 


$mac_bytes = explode(\":\", $mac); 
$mac_addr = \"\"; 
for ($i=0; $i<6; $i++) 
$mac_addr .= chr(hexdec($mac_bytes[$i])); 
$packet = \"\"; 
for ($i=0; $i<6; $i++)  /*6x 0xFF*/ 
$packet .= chr(255); 
for ($i=0; $i<16; $i++) /*16x MAC address*/ 
$packet .= $mac_addr; 

$port = $porttemp; 
$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP); 
socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, TRUE); 
socket_sendto($sock, $packet, strlen($packet), 0, $ip, $port); 
socket_close($sock); 
")
    do shell script command
end run

不管怎样，我终于让它工作了。不知道它到底是什么，但这里的代码是为那些想要通过 PHP 在 Objective C 环境中通过 Applescript 作为 shell 脚本运行 WOL（局域网唤醒）魔术包的 php 脚本的人提供的。是的。这是经过编辑和工作的：

NSString *asString = [[NSString alloc] initWithFormat:@"property MACaddr : \"gg:gg:gg:gg:gg:gg\"\n property WAN_IP_address : \"255.255.255.255\"\n property port_number : \"9\"\n "
                    "on run\n set command to \"/usr/bin/php -r \" & quoted form of (\"$mac = \" & quoted form of MACaddr & \"; $porttemp = \" & quoted form of port_number & \";$ip = \" & quoted form of WAN_IP_address & \"; \" & \"\n" 
                                        "$mac_bytes = explode(\\\":\\\", $mac);\n "
                                          " $mac_addr = \\\"\\\";\n "
                                          " for ($i=0; $i<6; $i++) "
                                          " $mac_addr .= chr(hexdec($mac_bytes[$i]));\n" 
                                          " $packet = \\\"\\\";\n "
                                          " for ($i=0; $i<6; $i++)\n     "
                                          " $packet .= chr(255);\n "
                                           "for ($i=0; $i<16; $i++)\n    "
                                           "$packet .= $mac_addr;\n" 
                                          " $port = $porttemp;\n "
                                           "$sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);\n" 
                                           "socket_set_option($sock, SOL_SOCKET, SO_BROADCAST, TRUE);\n" 
                                           "socket_sendto($sock, $packet, strlen($packet), 0, $ip, $port);\n" 
                                           "socket_close($sock);\")\n "
                                           "do shell script command \n"
                                            "end run"   ];
NSLog(@"the applescript %@", asString);
NSString *script2 = [asString stringByReplacingOccurrencesOfString:@"gg:gg:gg:gg:gg:gg" withString:AirportMAC];
NSAppleScript *asScript = [[NSAppleScript alloc] initWithSource:script2];
[asScript executeAndReturnError:nil];
[asString release];
[asScript release];

非常感谢大家的帮助！

Answer 1

永远不要这样做：

NSLog([asScript stringValue]);

总是这样做：

NSLog("%@",[asScript stringValue]);

将未知格式字符串传递给 NSLog() 是通往崩溃箱的快速路径。

Answer 2

绝对是反斜杠字符的问题。 NSLog 你的 asString 变量并尝试在编辑器中运行打印的代码，你会看到错误。

如果字符串中有引号，则需要三个反斜杠！

"$mac_bytes = explode(\":\", $mac); "

应该是

"$mac_bytes = explode(\\\":\\\", $mac); "

，其他地方也是如此。
