我正在做一个教程,涉及iframe src属性的设置:
<iframe width="100%" height="300" src="{{video.url}}"></iframe>
这会抛出一个异常:
Error: unsafe value used in a resource URL context
at DomSanitizationServiceImpl.sanitize...
我已经尝试使用[src]绑定,但没有成功。

当前回答
说实话,所有的答案似乎都是错的。使用this. saniizer . bypasssecuritytrustresourceurl (url)仅绕过安全性,并将url视为SafeResourceUrl。但是,给定的url仍然可能是恶意的,导致安全违规。医生也这么说:https://angular.io/api/platform-browser/DomSanitizer#bypassSecurityTrustResourceUrl
一个解决方案是首先调用sanitizer,然后将sanitizer的返回值传递给bypassSecurityTrustResourceUrl,如下所示:
this.sanitizer.bypassSecurityTrustResourceUrl (this.sanitizer.sanitize (SecurityContext。URL、URL))
通过这种方式,您可以清除任何恶意代码,然后绕过表示这确实是一个安全url的安全性。
其他回答
这样我就可以使用Angular 5.2.0了
fileName.Component.ts
import { Component, OnInit, Input } from '@angular/core';
import { DomSanitizer, SafeResourceUrl } from '@angular/platform-browser';
@Component({
selector: 'app-sample',
templateUrl: './fileName.component.html',
styleUrls: ['./fileName.component.scss']
})
export class FileName implements OnInit {
@Input()
url: string = "https://www.mmlpqtpkasjdashdjahd.com";
urlSafe: SafeResourceUrl;
constructor(public sanitizer: DomSanitizer) { }
ngOnInit() {
this.urlSafe= this.sanitizer.bypassSecurityTrustResourceUrl(this.url);
}
}
fileName.Component.html
<iframe width="100%" height="100%" frameBorder="0" [src]="urlSafe"></iframe>
伙计们,就这些!!
这对我很有用
我在iframe中定义了一个id
<iframe id="embeddedPage"></iframe>
在组件中,我使用了这段代码
export class YourComponent implements OnInit {
constructor() {}
ngOnInit(): void {
const iframe = document.getElementById('embeddedPage') as HTMLIFrameElement;
iframe.contentWindow.location.replace('your url');
}
}
我也遇到过这个问题,但为了在我的angular模块中使用安全管道,我安装了安全管道npm包,你可以在这里找到。仅供参考,这在Angular 9.1.3中是有效的,我还没有在其他版本的Angular中尝试过。下面是如何一步一步地添加它:
Install the package via npm install safe-pipe or yarn add safe-pipe. This will store a reference to it in your dependencies in the package.json file, which you should already have from starting a new Angular project. Add SafePipeModule module to NgModule.imports in your Angular module file like so: import { SafePipeModule } from 'safe-pipe'; @NgModule({ imports: [ SafePipeModule ] }) export class AppModule { } Add the safe pipe to an element in the template for the Angular component you are importing into your NgModule this way:
<element [property]="value | safe: sanitizationType"></element>
下面是一些在html元素中使用safePipe的具体例子:
<div [style.background-image]="'url(' + pictureUrl + ')' | safe: 'style'" class="pic bg-pic"></div>
<img [src]="pictureUrl | safe: 'url'" class="pic" alt="Logo">
<iframe [src]="catVideoEmbed | safe: 'resourceUrl'" width="640" height="390"></iframe>
<pre [innerHTML]="htmlContent | safe: 'html'"></pre>
祝贺!¨^ ^ 我有一个简单有效的解决方案给你,是的!
<iframe width="100%" height="300" [attr.src]="video.url"></iframe
[attr。Src]而不是Src ”视频。而不是{{video.url}}
伟大的,)
我通常添加单独的安全管道可重用组件如下
# Add Safe Pipe
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Pipe({name: 'mySafe'})
export class SafePipe implements PipeTransform {
constructor(private sanitizer: DomSanitizer) {
}
public transform(url) {
return this.sanitizer.bypassSecurityTrustResourceUrl(url);
}
}
# then create shared pipe module as following
import { NgModule } from '@angular/core';
import { SafePipe } from './safe.pipe';
@NgModule({
declarations: [
SafePipe
],
exports: [
SafePipe
]
})
export class SharedPipesModule {
}
# import shared pipe module in your native module
@NgModule({
declarations: [],
imports: [
SharedPipesModule,
],
})
export class SupportModule {
}
<!-------------------
call your url (`trustedUrl` for me) and add `mySafe` as defined in Safe Pipe
---------------->
<div class="container-fluid" *ngIf="trustedUrl">
<iframe [src]="trustedUrl | mySafe" align="middle" width="100%" height="800" frameborder="0"></iframe>
</div>
