在从0.10.2更新到0.12.2后，Node.js错误“ReferenceError：global is not defined”

以下代码用于在使用Node.jsredirect控制台的服务器上执行沙盒JavaScript代码。

在我们用Node.js 0.10.2更新Node.js 0.10.2之前，它的function就像一个魅力

 var EOL = require('os').EOL; DataView = undefined; DTRACE_NET_SERVER_CONNECTION = undefined; // DTRACE_NET_STREAM_END = undefined; DTRACE_NET_SOCKET_READ = undefined; DTRACE_NET_SOCKET_WRITE = undefined; DTRACE_HTTP_SERVER_REQUEST = undefined; DTRACE_HTTP_SERVER_RESPONSE = undefined; DTRACE_HTTP_CLIENT_REQUEST = undefined; DTRACE_HTTP_CLIENT_RESPONSE = undefined; COUNTER_NET_SERVER_CONNECTION = undefined; COUNTER_NET_SERVER_CONNECTION_CLOSE = undefined; COUNTER_HTTP_SERVER_REQUEST = undefined; COUNTER_HTTP_SERVER_RESPONSE = undefined; COUNTER_HTTP_CLIENT_REQUEST = undefined; COUNTER_HTTP_CLIENT_RESPONSE = undefined; global = undefined; process.argv = undefined; process.versions = undefined; process.env = { NODE_DEBUG: false }; process.addListener = undefined; process.EventEmitter = undefined; process.mainModule = undefined; process.removeListener = undefined; process.config = undefined; // process.on = undefined; process.openStdin = undefined; process.chdir = undefined; process.cwd = undefined; process.umask = undefined; GLOBAL = undefined; root = undefined; setTimeout = undefined; setInterval = undefined; clearTimeout = undefined; clearInterval = undefined; setImmediate = undefined; clearImmediate = undefined; module = undefined; require = undefined; msg = undefined; delete DataView; delete DTRACE_NET_SERVER_CONNECTION; // delete DTRACE_NET_STREAM_END; delete DTRACE_NET_SOCKET_READ; delete DTRACE_NET_SOCKET_WRITE; delete DTRACE_HTTP_SERVER_REQUEST; delete DTRACE_HTTP_SERVER_RESPONSE; delete DTRACE_HTTP_CLIENT_REQUEST; delete DTRACE_HTTP_CLIENT_RESPONSE; delete COUNTER_NET_SERVER_CONNECTION; delete COUNTER_NET_SERVER_CONNECTION_CLOSE; delete COUNTER_HTTP_SERVER_REQUEST; delete COUNTER_HTTP_SERVER_RESPONSE; delete COUNTER_HTTP_CLIENT_REQUEST; delete COUNTER_HTTP_CLIENT_RESPONSE; delete global; delete process.argv; delete process.versions; delete GLOBAL; delete root; delete setTimeout; delete setInterval; delete clearTimeout; delete clearInterval; delete setImmediate; delete clearImmediate; delete module; delete require; delete msg; var content = ''; process.stdin.resume(); process.stdin.on('data', function(buf) { content += buf.toString(); }); process.stdin.on('end', function() { var inputData = content.trim().split(EOL); var result = code.run(inputData); if (result !== undefined) { console.log(result); } }); var code = { run: function Solve(args) { console.log('works'); } }; 

现在代码抛出一个exception：

 util.js:67 if (isUndefined(global.process)) { ^ ReferenceError: global is not defined at Object.exports.deprecate (util.js:67:19) at net.js:1414:34 at NativeModule.compile (node.js:805:5) at NativeModule.require (node.js:774:18) at tty.js:23:11 at NativeModule.compile (node.js:805:5) at Function.NativeModule.require (node.js:774:18) at process.stdin (node.js:533:34) at Object.<anonymous> (C:\Program Files\nodejs\test.js:75:8) at Module._compile (module.js:460:26) 

我的第75行是：

 process.stdin.resume(); 

这个问题是否与stream程variables有关，如果是这样的话，我怎么能在Node.js 0.12.2中使用stdin / stdout来读/写？

另外如果问题是与process.stdin.resume(); 我怎样才能达到相同的结果使用Node.js 0.12.2？

编辑

正如文件所述

过程对象是一个全局对象，可以从任何地方访问。

哪一个更令人困惑，因为exception是ReferenceError: global is not defined在process.stdin.resume();上ReferenceError: global is not defined process.stdin.resume(); 。

Answer 1

global = undefined;

delete global;

不要这样做。
