如何在不显示我的 API 键的情况下使此代码工作?我正在 Node 上构建应用程序。js/Angular/Express

How can I make this code work without showing my API keys? I am building as app on Node.js/Angular/Express

此代码适用于我的应用程序,但 process.env 不适用于此函数。有没有一种方法可以让我调用 process.env 而不必显示我的密钥?如果我现在保留代码,API 调用将不起作用,但如果我添加我的密钥,它将起作用。我的选择是什么,或者为什么 process.env 不能像在命令行上那样在此处工作?

function randomString(length, chars) {
    var result = '';
    for (var i = length; i > 0; --i) result += chars[Math.round(Math.random() * (chars.length - 1))];
    return result;
}

var myApp = angular.module('myApp', []);

myApp.controller('MainCtrl', ['$scope', 'MyYelpAPI', '$window', function($scope, MyYelpAPI, $window) {
    $scope.total = [];
    $scope.businesses = [];
    MyYelpAPI.retrieveYelp('', function(data) {
        $scope.businesses = data.businesses
        console.log($scope.businesses)

        var array = $scope.businesses
        var random = Math.floor((Math.random() * array.length) + 1);
        // console.log(array[random])

        var result = array[random]
        console.log(result)

        if (2 > 1) {
            $scope.businesses = [result]
        }
    });

}]).factory("MyYelpAPI", function($http) {
    return {
        "retrieveYelp": function(name, callback) {
            var method = 'GET';
            var url = 'http://api.yelp.com/v2/search?';
            var params = {
                    callback: 'angular.callbacks._0',
                    location: 'New+York',
                    oauth_consumer_key: process.env.yelp_consumer_key, //Consumer Key
                    oauth_token: process.env.yelp_token, //Token
                    oauth_signature_method: "HMAC-SHA1",
                    oauth_timestamp: new Date().getTime(),
                    oauth_nonce: randomString(32, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'),
                    term: 'bakery'
                    // limit: 15
                };
            var consumerSecret = process.env.yelp_consumer_secret; //Consumer Secret
            var tokenSecret = process.env.yelp_token_secret; //Token Secret
            var signature = oauthSignature.generate(method, url, params, consumerSecret, tokenSecret, { encodeSignature: false});
            params['oauth_signature'] = signature;
            $http.jsonp(url, {params: params}).success(callback);
        }
    }
});

您无权访问客户端的 process.env,这只会让您访问 Node 环境。您应该做的是将 api 调用功能移动到应用程序的服务器(节点)部分,并让您的 angular 工厂查询服务器代码提供的端点。在您的服务器中,您可以访问 process.env,并安全地存储您的 env 密钥对,从而永远不会将它们暴露给 public.

一个非常基本的大纲(假设您正在本地开发并在 http://localhost:3000/api 上托管您的 api 可能是:

// client side angular code

.factory("MyYelpAPI", function($http) {
    return {
        "retrieveYelp": function(name, callback) {
            var method = 'GET';
            var url = 'localhost:3000/api/search';
            var params = {
                ...
            };

            ...

            $http.jsonp(url, {params: params}).success(callback);
        }
    }
});

// node/express routing

app.get('/api/search', require('./api.js').search)

// server side i.e. node code (api.js)

module.exports = {
    search: function(req, res) {
        var params = {
            oauth_consumer_key: process.env.yelp_consumer_key, //Consumer Key
            oauth_token: process.env.yelp_token, //Token
        }

        ...

        res.json(something);
    }
}
