Question

当我尝试从cmd行执行js文件时，出现此错误。我不确定是否可以提供这样的钥匙。

const App42 = require('./js/App42-all-1.6.min');
const mod = require('./js/buddy');

module.exports = {

var API_KEY = '014883a05a4902889c860272b3c4*******568072cf82cfc31a42c165f0f8cc6';
var SEC_KEY = 'b3b2df57b86a7fdabe66a96a*******7e04fbd95c6ddef942a3c844878eafbf05';


App42.initialize(API_KEY,SEC_KEY); 

hello: function() {
  return "Hello";
}
}

我遇到的错误是：

LB.js:6
    var APIKEY = '014883a05a4902889c860272b3c2170ae145*****2cf82cfc31a42c165f0f8cc6';
        ^^^^^^

在放弃投票之前，可以有人说解决方案。这不是您对尝试学习js的新用户的反应。

您正在导出对象，但是对象语法无效：

module.exports = {
//Shouldn't be using var here as it's just a property of an object
var API_KEY = '014883a05a4902889c860272b3c4*******568072cf82cfc31a42c165f0f8cc6';
var SEC_KEY = 'b3b2df57b86a7fdabe66a96a*******7e04fbd95c6ddef942a3c844878eafbf05';

//Shouldn't be calling a function here as it's also in the object definition
App42.initialize(API_KEY,SEC_KEY); 

hello: function() {
  return "Hello";
}
}

您应该只导出对象的键和值。因此，根据您要实际“导出”的内容，您可以尝试

API_KEY:'014883a05a4902889c860272b3c4*******568072cf82cfc31a42c165f0f8cc6',
SEC_KEY:'b3b2df57b86a7fdabe66a96a*******7e04fbd95c6ddef942a3c844878eafbf05',
App42.initialize(API_KEY,SEC_KEY); 
module.exports = {

 API_KEY:API_KEY,
 SEC_KEY:SEC_KEY,
 App42: App42,



hello: function() {
  return "Hello";
}
}

然后require这个文件时，您可以访问各种属性和功能，例如

const foo = require('./myfile');
console.log(foo.App42);
console.log(foo.hello());
console.log(foo.API_KEY);

这里的问题是，您直接在对象声明（module.exports）内部声明变量并运行函数，这就是为什么它不编译。

您应该执行以下操作：

const App42 = require('./js/App42-all-1.6.min');
const mod = require('./js/buddy');

const API_KEY = '014883a05a4902889c860272b3c4*******568072cf82cfc31a42c165f0f8cc6';
const SEC_KEY = 'b3b2df57b86a7fdabe66a96a*******7e04fbd95c6ddef942a3c844878eafbf05';
App42.initialize(API_KEY,SEC_KEY); 

module.exports = {
  hello: function() {
    return "Hello";
  }
}

js给出了意外的标识符
