Internet Explorer &Angular 6 错误错误:未捕获(承诺):错误:加载块 [英] Internet explorer & Angular 6 ERROR Error: Uncaught (in promise): Error: Loading chunk
问题描述
我在使用 angular 6 和 IE 11 时遇到问题，应用程序在 chrome & 中运行良好另一个浏览器，但在 Internet Explorer 中，我得到了这个
<块引用>ERROR Error: Uncaught (in promise): Error: Loading chunk默认~app-xxxxx~eb5ba6d4失败的.(缺失:http://localhost:4200/default~app-xxxx.js) 错误:加载块 default~app-xxxx~eb5ba6d4 失败.(丢失的:http://localhost:4200/default~app-xxxx~eb5ba6d4.js)

我的应用路由是
const 路由:Routes = [{小路: ''，loadChildren: 'app/content/pages/pages.module#PagesModule'},{路径:'布局'，loadChildren: 'app/content/layout/layout.module#LayoutModule',},{小路: '**'，重定向到:''}];经过几个小时的努力终于找到了我的解决方案关于 promise((t,n) => ,
的问题- 首先打开src/polyfills.ts文件，取消注释
<块引用>
/** IE9、IE10 和 IE11 需要以下所有 polyfill.**///导入 'core-js/es6/symbol';//导入 'core-js/es6/object';//导入 'core-js/es6/function';//导入 'core-js/es6/parse-int';//导入 'core-js/es6/parse-float';//导入 'core-js/es6/number';//导入 'core-js/es6/math';//导入 'core-js/es6/string';//导入 'core-js/es6/date';//导入 'core-js/es6/array';//导入 'core-js/es6/regexp';//导入 'core-js/es6/map';//导入 'core-js/es6/weak-map';//导入 'core-js/es6/set';=> lambda 表达式在 IE 中不支持，所以我们可以用代码 function() 代替这个表达式.
安装一些包
npm install --save web-animations-js
npm install --save classlist.js
然后我从 npm 包 (fuctbase64/index.js) 之一中发现了 promise 问题
module.exports = 函数(事件){返回新的承诺((解决，拒绝)=> {let reader = new FileReader();让文件 = event.target.files;让 len = files.length;如果 (len > 1) {拒绝(new DOMException("一次只能上传一个文件"));} 别的 {reader.onerror = () =>{reader.abort();拒绝(新的DOMException(解析输入文件时出现问题."))；};让文件 = 文件 [0]reader.onload = (evt) =>{const uint = new Uint8Array(evt.target.result);让字节 = [];uint.map(byte => {bytes.push(byte.toString(16));});const hex = bytes.join('').toUpperCase();让 base64 = reader.result.split(',')[1];文件.base64 = base64;file.binaryFileType = getMimetype(hex);解决(文件)；};reader.readAsDataURL(文件)；}});}用
替换代码module.exports = 函数(事件){返回新的承诺(功能(解决，拒绝){let reader = new FileReader();让文件 = event.target.files;让 len = files.length;如果 (len > 1) {拒绝(new DOMException("一次只能上传一个文件"));} 别的 {reader.onerror = function() {reader.abort();拒绝(新的DOMException(解析输入文件时出现问题."))；};让文件 = 文件 [0]reader.onload = 函数(evt){const uint = new Uint8Array(evt.target.result);让字节 = [];uint.map(函数(字节){bytes.push(byte.toString(16));});const hex = bytes.join('').toUpperCase();让 base64 = reader.result.split(',')[1];文件.base64 = base64;file.binaryFileType = getMimetype(hex);解决(文件)；};reader.readAsDataURL(文件)；}});}I am getting issue while using angular 6 and IE 11, app is working fine in chrome & another browser but in internet explorer, i am getting this
ERROR Error: Uncaught (in promise): Error: Loading chunk default~app-xxxxx~eb5ba6d4 failed. (missing: http://localhost:4200/default~app-xxxx.js) Error: Loading chunk default~app-xxxx~eb5ba6d4 failed. (missing: http://localhost:4200/default~app-xxxx~eb5ba6d4.js)

My app routing is
const routes: Routes = [
{
path: '',
loadChildren: 'app/content/pages/pages.module#PagesModule'
},
{
path: 'layout',
loadChildren: 'app/content/layout/layout.module#LayoutModule',

{
path: '**',
redirectTo: ''
}
];
After investing some hours finally found my solutions Issue about promise((t,n) => ,
- At first, open the src/polyfills.ts file, and uncomment
/** IE9, IE10 and IE11 requires all of the following polyfills. **/ // import 'core-js/es6/symbol'; // import 'core-js/es6/object'; // import 'core-js/es6/function'; // import 'core-js/es6/parse-int'; // import 'core-js/es6/parse-float'; // import 'core-js/es6/number'; // import 'core-js/es6/math'; // import 'core-js/es6/string'; // import 'core-js/es6/date'; // import 'core-js/es6/array'; // import 'core-js/es6/regexp'; // import 'core-js/es6/map'; // import 'core-js/es6/weak-map'; // import 'core-js/es6/set';
=> lambda expression does not support in IE so we can replace with code function() instead of this expression.
Install some packages
npm install --save web-animations-js
npm install --save classlist.js
Then i was found promise issue from one of the npm package (fuctbase64/index.js)
module.exports = function (event) {
return new Promise((resolve, reject) => {
let reader = new FileReader();
let files = event.target.files;
let len = files.length;
if (len > 1) {
reject(new DOMException("Only one file can be uploaded at a time"));
} else {
reader.onerror = () => {
reader.abort();
reject(new DOMException("Problem parsing input file."));
};
let file = files[0]
reader.onload = (evt) => {
const uint = new Uint8Array(evt.target.result);
let bytes = [];
uint.map(byte => {
bytes.push(byte.toString(16));
});
const hex = bytes.join('').toUpperCase();
let base64 = reader.result.split(',')[1];
file.base64 = base64;
file.binaryFileType = getMimetype(hex);
resolve(file);
};
reader.readAsDataURL(file);
}
});
}
Replace code with
module.exports = function (event) {
return new Promise(function(resolve, reject) {
let reader = new FileReader();
let files = event.target.files;
let len = files.length;
if (len > 1) {
reject(new DOMException("Only one file can be uploaded at a time"));
} else {
reader.onerror = function() {
reader.abort();
reject(new DOMException("Problem parsing input file."));
};
let file = files[0]
reader.onload = function(evt){
const uint = new Uint8Array(evt.target.result);
let bytes = [];
uint.map(function(byte) {
bytes.push(byte.toString(16));
});
const hex = bytes.join('').toUpperCase();
let base64 = reader.result.split(',')[1];
file.base64 = base64;
file.binaryFileType = getMimetype(hex);
resolve(file);
};
reader.readAsDataURL(file);
}
});
}
