谷歌的reCAPTCHA - systemjs丢失

Question

我正在尝试在角度上实现谷歌的reCAPTCHA this tutorial
我在Angular CLI项目中找不到systemjs.config.js。如何解决这个问题？

你需要创建一个 “systemjs.config.js” 文件，并从index.html的加载它，像楷书

<script src="node_modules/systemjs/dist/system.src.js"></script> 
<script src="systemjs.config.js"></script> 

（!!!重要，你应该包括system.src.js前systemjs.config.js文件）

这是SystemJS.config.js示例文件

/** 
* System configuration for Angular 2 samples 
* Adjust as necessary for your application needs. 
*/ 
(function(global) { 
    // map tells the System loader where to look for things 
    var map = { 
    'app':      'app', // 'dist', 
    '@angular':     'node_modules/@angular', 
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api', 
    'rxjs':      'node_modules/rxjs' 
    }; 
    // packages tells the System loader how to load when no filename and/or no extension 
    var packages = { 
    'app':      { main: 'main.js', defaultExtension: 'js' }, 
    'rxjs':      { defaultExtension: 'js' }, 
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' }, 
    }; 
    var ngPackageNames = [ 
    'common', 
    'compiler', 
    'core', 
    'forms', 
    'http', 
    'platform-browser', 
    'platform-browser-dynamic', 
    'router', 
    'router-deprecated', 
    'upgrade', 
    ]; 
    // Individual files (~300 requests): 
    function packIndex(pkgName) { 
    packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' }; 
    } 
    // Bundled (~40 requests): 
    function packUmd(pkgName) { 
    packages['@angular/'+pkgName] = { main: 'bundles/' + pkgName + '.umd.js', defaultExtension: 'js' }; 
    } 
    // Most environments should use UMD; some (Karma) need the individual index files 
    var setPackageConfig = System.packageWithIndex ? packIndex : packUmd; 
    // Add package entries for angular packages 
    ngPackageNames.forEach(setPackageConfig); 
    var config = { 
    map: map, 
    packages: packages 
    }; 
    System.config(config); 
})(this);
