Question

我有以下shell脚本，用于修改cordova应用程序的facebook插件的plist。

#!/bin/bash                                                                                                    

# Put this in /hooks/after_prepare/
PLIST=platforms/ios/*/*-Info.plist                                                                             

cat << EOF |

在cordova hooks guide上，建议在node.js中写入钩子，以便它们是跨平台的。另外，我是一个Windows用户，所以这个脚本在我的系统上不起作用。我提到this文章尝试使用节点将shell脚本转换为javascript但我不完全理解shell脚本。如何将此脚本转换为在节点中执行？

修改我意识到我需要解释脚本中我不理解的内容。前3行，我理解它是将文件放在变量PLIST

中

第4行是here标签。在此之前我可以编写javascript来读取来自platforms / ios / / -Info.plist的文件

var fs = require ('fs');

var PLIST = fs.readFileSync(fileName);

我不明白接下来的几行是做什么的。我理解的唯一部分是删除：LSApplicationQueriesSchemes，它删除一些变量或名为LSApplicationQueriesSchemes的部分，并可能用新值重写。

您可以使用plist包生成/更新plist文件。这是一般流程（已授予，您只有一个.plist文件）：

var fs = require('fs');
var path = require('path');
var glob = require('glob');
var plist = require('plist');
var _ = require('lodash');

var p = path.normalize(__dirname + '/platforms/ios/*/*-Info.plist');
var files = glob.sync(p);

// if you have only one file
var filename = files[0];

// parse the original file
var obj = plist.parse(fs.readFileSync(filename, 'utf8'));

// build an object with everything to add
var objToAdd = {
  NSAppTransportSecurity: {
    NSAllowsArbitraryLoads: true,
    NSExceptionDomains: {
      'fbcdn.net': {
        NSIncludesSubdomains: true,
        NSThirdPartyExceptionRequiresForwardSecrecy: false
      },
      // ...
    }
  }
}

// modify the original loaded data for 'Delete :LSApplicationQueriesSchemes'
obj.LSApplicationQueriesSchemes = [
  'fbapi',
  'fbapi20130214',
  'fbapi20130410',
  // ...
];

// merge the 2 objects
var finalObj = _.merge(obj, objToAdd);

// build the plist
var finalPlist = plist.build(finalObj);

// write back to the file
fs.writeFileSync(filename, finalPlist);

毋庸置疑，您必须仔细比较bash生成的文件和nodejs，以确保您获得相同的结果。
