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。

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!!

更新v8

下面回答工作,但暴露您的应用程序的XSS安全风险! 与其使用this. domsaniizer . bypasssecuritytrustresourceurl (url),不如使用this. domsaniizer .sanitize(SecurityContext. sanitize)。URL, URL)

更新

对于RC.6^版本使用DomSanitizer

砰砰作响

一个好的选择是使用纯管道:

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer} from '@angular/platform-browser';

@Pipe({ name: 'safe' })
export class SafePipe implements PipeTransform {
  constructor(private domSanitizer: DomSanitizer) {}
  transform(url) {
    return this.domSanitizer.bypassSecurityTrustResourceUrl(url);
  }
} 

记得把你的新SafePipe添加到AppModule的declarations数组中。(详见文件)

@NgModule({
   declarations : [
     ...
     SafePipe
   ],
})

html

<iframe width="100%" height="300" [src]="url | safe"></iframe>

砰砰作响

如果你使用嵌入标签,这可能对你很有趣:

旧版RC.5

你可以像这样利用DomSanitizationService:

export class YourComponent {
  url: SafeResourceUrl;
  constructor(domSanitizationService: DomSanitizationService) {
    this.url = domSanitizer.bypassSecurityTrustResourceUrl('your url');
  }
}

然后在模板中绑定到url:

<iframe width="100%" height="300" [src]="url"></iframe>

不要忘记添加以下导入:

import { SafeResourceUrl, DomSanitizationService } from '@angular/platform-browser';

砰砰作响的样本

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,)

constructor(
 public sanitizer: DomSanitizer, ) {

 }

我已经挣扎了4个小时。问题出在img标签。当你使用方括号的'src' ex: [src]。你不能使用这个角表达式{{}}。你只要直接从下面的实物例子给出。如果你给出角表达式{{}}。你会得到插值误差。

首先,我用ngFor来迭代国家 *ngFor="让国家中的国家" 然后你把这个放到img标签里。就是它了。 < img (src) = " sanitizer.bypassSecurityTrustResourceUrl (country.flag)” Height ="20" width="20" alt=""/> .

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>
