在我的 angular2 应用程序中,我试图从不同的服务器加载 typescript 编译的 javascript。当我尝试加载不带 .js 扩展名的 javascript 文件时,它会进行不带 .js 扩展名的休息调用并给出 404 错误。
error
VM9887:1274 GET http://localhost:9099/OfferFinder7oct/app/app.module 404 (Not Found)
in detail the error is the systemjs is trying to load http://localhost:3000/app/app.module as "./app.module" but unable to reach http://localhost:3000/app/main.js
System.import('app').catch(function(err){ console.error(err); });
//system.config.js
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',

'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
'@angular/upgrade': 'npm:@angular/upgrade/bundles/upgrade.umd.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular-in-memory-web-api': 'npm:angular-in-memory-web-api',
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
最佳答案
将 defaultExtension: 'js'
添加到您的配置主要部分。您的配置不理解没有任何扩展名的文件的默认扩展名。
新配置看起来像这样
(function (global) {
System.config({
defaultExtension: 'js',
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
