OS.File设置chown和chmod（创建受信任的启动器 - Ubuntu的）

本文介绍了OS.File设置chown和chmod（创建受信任的启动器 - Ubuntu的）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用下面的代码：

Cu.import（'resource：//gre/modules/FileUtils.jsm'）;
var exe = FileUtils.getFile（'XREExeF'，[]）;
var args ='-P -dev -no-remote';

  var name =mysc; 
 var target = exe; 
 var cmd =[Desktop Entry] \\\
; 
 cmd + =Name =+ name +\\\
; 
 cmd + =Type = Application \\\
; 
 cmd + =Comment = Web Application \\\
; 
 cmd + =Exec =+ target.path ++ args +\\\
; 
 // cmd + =Icon =+ icon.path +\\\
; 
 
 Cu.import（resource：//gre/modules/osfile.jsm）
 var path = OS.Path.join（OS.Constants.Path.desktopDir，'mysc。桌面'）; 
 Services.ww.activeWindow.alert（path）
 
 let encoder = new TextEncoder（）; 
 let array = encoder.encode（cmd）; 
 let promise = OS.File.writeAtomic（path，array，{tmpPath：file.txt.tmp}）; 
 promise.then（
 function（aVal）{
 Services.ww.activeWindow.alert（'success aVal ='+ uneval（aVal））; 
}，
函数（aRejReas）{
 Services.ww.activeWindow.alert（'因为原因被拒绝：'+ uneval（aRejReas））
} 
）

如何设置chown和chmod？

我发现这个代码

  UnixFile .chmod = 
 declareFFI（chmod，ctypes.default_abi，
 * * return * / 
 Types.negativeone_or_nothing，
 / * path * / 
 Types.path ，
 / * mode * / 
 Types.mode_t）; 
 UnixFile.chown = 
 declareFFI（chown，ctypes.default_abi，$ b $ / * return * / 
 Types.negativeone_or_nothing，
 / * path * / 
 Types.path，
 / * uid * / 
 Types.uid_t，
 / * gid * / 
 Types.gid_t）;

有人告诉我设置 chown noi 和 chmod + x ，因为我的桌面路径是： /home/noi/Desktop/mysc.desktop 会修正这个错误：

也许 OS.File.setPermissions ？

我试过这个，但是没有成功：

  var promise2 = OS.File.setPermissions（path，{
 unixMode：OS.Constants.libc.S_IRWXO 
}）; 
 promise2.then（
 function（aVal）{
 console.log（'promise2 success'，'aVal：'，aVal）; 
}，
 function aReason）{
 console.warn（'promise2 rejected'，'aReason：'，aReason）; 
} 
）;

解决方案

我不知道如何设置chown chmod，但我能够创建该文件作为受信任。它是沿着 OS.File.setPermission 的行，但由于某些原因使用 unixMod 和 OSConstants.libc.S_I * 就像推荐的文档不对。

这是我制作一个值得信赖的桌面快捷方式： / p>

  Cu.import（'resource：//gre/modules/FileUtils.jsm'）; 
 Cu.import（resource：//gre/modules/osfile.jsm）
 
 var exe = FileUtils.getFile（'XREExeF'，[]）; 
 var args ='-P dev -no-remote'; 
 
 var name =Mozilla Firefox  -  dev; 
 var target = exe; 
 var icon_path = OS.Path.join（OS.Constants.Path.desktopDir，'beta.png'）; 
 var cmd =[Desktop Entry] \\\
; 
 cmd + =Name =+ name +\\\
; 
 cmd + =Type = Application \\\
; 
 cmd + =Comment = Web Application \\\
; 
 cmd + =Exec =+ target.path ++ args +\\\
; 
 cmd + =Icon =+ icon_path +\\\
; 
 
 
 var path = OS.Path.join（OS.Constants.Path.desktopDir，'mysc.desktop'）; 
 
 let encoder = new TextEncoder（）; 
 let array = encoder.encode（cmd）; 
 let promise = OS.File.writeAtomic（path，array，{tmpPath：file.txt.tmp}）; 
 promise.then（
 function（aVal）{
 console.log（'aVal'，aVal）; 
 var promise2 = OS.File.setPermissions（path，{unixMode： 
 promise2.then（
 function（aVal）{
 console.log（'promise2 success'，'aVal：'，aVal）; 
}，
函数（aReason）{
 console.warn（'promise2 rejected'，'aReason：'，aReason）; 
} 
）; 
}，
函数（aRejReas）{
 Services.ww.activeWindow.alert（'rejected by reason：'+ uneval（aRejReas））
} 
）;

注意 0o4777 而不是 OS.Constants.libc.S_IRWXO ，它的奇怪，我没有想到这一切，只是幸运的搜索github代码库。

I'm trying to create a shortcut that launches a profile on the desktop in Linux.

I'm using this code:

Cu.import('resource://gre/modules/FileUtils.jsm');var exe = FileUtils.getFile('XREExeF', []);var args = '-P -dev -no-remote';

var name = "mysc";
var target = exe;
var cmd = "[Desktop Entry]\n";
cmd += "Name=" + name + "\n";
cmd += "Type=Application\n";
cmd += "Comment=Web Application\n";
cmd += "Exec=" + target.path + " " + args + "\n";
//cmd += "Icon=" + icon.path + "\n";

Cu.import("resource://gre/modules/osfile.jsm")
var path = OS.Path.join(OS.Constants.Path.desktopDir, 'mysc.desktop');
Services.ww.activeWindow.alert(path)

let encoder = new TextEncoder();
let array = encoder.encode(cmd);
let promise = OS.File.writeAtomic(path, array, {tmpPath: "file.txt.tmp"});
promise.then(
  function(aVal) {
    Services.ww.activeWindow.alert('success aVal = ' + uneval(aVal));
  },
  function(aRejReas) {
    Services.ww.activeWindow.alert('rejected for reason: ' + uneval(aRejReas))
  }
)

How can i set chown and chmod?

I found this code https://github.com/johnshih/releases-mozilla-aurora/blob/dc29053a4b1765cf94a8562130865036c373038e/toolkit/components/osfile/osfile_unix_back.jsm#L218

UnixFile.chmod =
    declareFFI("chmod", ctypes.default_abi,
        /*return*/
        Types.negativeone_or_nothing,
        /*path*/
        Types.path,
        /*mode*/
        Types.mode_t);
 UnixFile.chown =
    declareFFI("chown", ctypes.default_abi,
        /*return*/
        Types.negativeone_or_nothing,
        /*path*/
        Types.path,
        /*uid*/
        Types.uid_t,
        /*gid*/
        Types.gid_t);

Someone told me to set chown noi and chmod +x on the file because my path to desktop is: /home/noi/Desktop/mysc.desktop will fix this error here:

Maybe OS.File.setPermissions?

I tried this but it didnt work:

    var promise2 = OS.File.setPermissions(path, {
        unixMode: OS.Constants.libc.S_IRWXO
    });
    promise2.then(
        function(aVal) {
            console.log('promise2 success', 'aVal:', aVal);
        },
        function(aReason) {
            console.warn('promise2 rejected', 'aReason:', aReason);
        }
    );

解决方案

I didn't figure out how to set chown and chmod but I was able to create the file as trusted. It was along the lines of OS.File.setPermission but for some reason using unixMod and the flags of OSConstants.libc.S_I* like the docs recommended was not right.

This is how I made a trusted desktop shortcut:

Cu.import('resource://gre/modules/FileUtils.jsm');
Cu.import("resource://gre/modules/osfile.jsm")

var exe = FileUtils.getFile('XREExeF', []);
var args = '-P dev -no-remote';

var name = "Mozilla Firefox - dev";
var target = exe;
var icon_path = OS.Path.join(OS.Constants.Path.desktopDir, 'beta.png');
var cmd = "[Desktop Entry]\n";
cmd += "Name=" + name + "\n";
cmd += "Type=Application\n";
cmd += "Comment=Web Application\n";
cmd += "Exec=" + target.path + " " + args + "\n";
cmd += "Icon=" + icon_path + "\n";


var path = OS.Path.join(OS.Constants.Path.desktopDir, 'mysc.desktop');

let encoder = new TextEncoder();
let array = encoder.encode(cmd);
let promise = OS.File.writeAtomic(path, array, {tmpPath: "file.txt.tmp"});
promise.then(
  function(aVal) {
    console.log('aVal', aVal);
    var promise2 = OS.File.setPermissions(path, {unixMode: 0o4777});
    promise2.then(
     function(aVal) {
       console.log('promise2 success', 'aVal:', aVal);
     },
      function(aReason) {
        console.warn('promise2 rejected', 'aReason:', aReason);
      }
    );
  },
  function(aRejReas) {
    Services.ww.activeWindow.alert('rejected for reason: ' + uneval(aRejReas))
  }
);

Notice the 0o4777 instead of OS.Constants.libc.S_IRWXO, its weird, I didn't expect this at all and just got lucky searching github code base.
