如何避免在node.js中使用模塊？

Question

這樣做tutorial，我不希望使用device.js只是把一行在它：module.exports = "<a1 ..

怎麼可以把這個設備ID在我的主腳本，並把它傳遞給apnagent對象？試過這個，但我想這就是爲什麼連接沒有建立。

也許而不是module.exports = "<388 ..我需要類似agent.set('something', and here the device ID);？

var pfx = '/var/lib/openshift/555dd1415973ca1660000085/app-root/runtime/repo/pfx.p12'; 
module.exports = "<38873D3B 0D61A965 C1323D6C 0A9F2866 D1BB50A3 64F199E5 483862A6 7F02049C>"; // <----- THIS HERE 

var apnagent = require('apnagent') 
var agent = module.exports = new apnagent.Agent(); 
agent.set('pfx file', pfx); 
// our credentials were for development 
agent.enable('sandbox'); 

console.log('LOG1'); 
console.log(agent); 
agent.connect(function (err) { 

console.log('LOG2'); 
    // gracefully handle auth problems 
    if (err && err.name === 'GatewayAuthorizationError') { 
    console.log('Authentication Error: %s', err.message); 
    process.exit(1); 
    } 

    // handle any other err (not likely) 
    else if (err) { 
    throw err; 
    } 

    // it worked! 
    var env = agent.enabled('sandbox') 
    ? 'sandbox' 
    : 'production'; 

    console.log('apnagent [%s] gateway connected', env); 
});

你可以試試這個：

var pfx = '/var/lib/openshift/555dd1415973ca1660000085/app-root/runtime/repo/pfx.p12'; 
var deviceId = "<38873D3B 0D61A965 C1323D6C 0A9F2866 D1BB50A3 64F199E5 483862A6 7F02049C>"; // <----- THIS HERE 

var apnagent = require('apnagent') 
var agent = new apnagent.Agent(deviceId); 
agent.set('pfx file', pfx); 
// our credentials were for development 
agent.enable('sandbox'); 

console.log('LOG1'); 
console.log(agent); 
agent.connect(function (err) { 

console.log('LOG2'); 
    // gracefully handle auth problems 
    if (err && err.name === 'GatewayAuthorizationError') { 
    console.log('Authentication Error: %s', err.message); 
    process.exit(1); 
    } 

    // handle any other err (not likely) 
    else if (err) { 
    throw err; 
    } 

    // it worked! 
    var env = agent.enabled('sandbox') 
    ? 'sandbox' 
    : 'production'; 

    console.log('apnagent [%s] gateway connected', env); 
}); 

的解釋是這樣的：module.exports是通用模塊輸出的語法。通過這種方式，您可以避免導出模塊並通過在代碼中手動硬編碼deviceId來導入模塊。
